Introduction
RAVPower has launched an impressive concentrate of portable power that features Quick Charge 3.0, the latest technology available from Qualcomm to charge QC 3.0 compatible devices much faster than using conventional charging technology, and even an USB Type-C port, that is becoming a standard nowadays with latest devices.
This is the RAVPower Turbo+ QC 3.0 20100mAh Battery Pack.

This is the updated version of the Power Bank from RAVPower with QC 3.0 (Turbo+) support instead of the previous QC 2.0 (Turbo, without the "+" character). Luckily I had the possibility to compare both versions, so I’ll show you both.
Unboxing
Packaging (eco-friendly) comes with two Slim Micro-USB cables (~26cm & ~66cm), a Protective Pouch, a small Multilanguage Quick Start Guide, a Warranty Card and the Power Bank (of course).
Both versions come with the same accessories, only packaging is different.
I must admit that this Power Bank impressed me because it seems bulky, but in reality it is pretty lightweight and small enough to be handled easily in your bag without sacrifying too much space. I like its clean design, with rounded borders and opaque painting.
Don’t forget that this is a 20100mAh Battery Pack, so if you are going to buy it so must consider that it isn’t as portable as less powerful ones. (Batteries technology is improving day-by-day though so in the future we might be able to get smaller – but not less powerful – batteries)
It weighs 376g, its chassis is made of Plastic (feels strong though) and on the front side there are 4 Blue LEDs used to check battery remaining charge with a power button. The power button is only used to check battery remaining charge so you don’t have to press it to turn on the power bank. It turns on automatically when you connect a device whatever port you are using.
It comes with multiple USB ports:
- 1x Micro-USB port that support also Quick Charge
- 1x USB Type-C port that can be used in both ways (Input and Output)
- 2x Full-Size USB Ports (1x with Quick Charge support)
As regards its performance, I am able to charge my Galaxy S4 (GT-I9500, Exynos Variant) at the same speed as with the Original Samsung Charger (with 2.0A output) without any voltage stability issue. (I have tested both USB Ports). I have also tried to charge a Galaxy S4 (GT-I9505, Qualcomm Variant) that comes with Quick Charge 1.0 technology support and it managed to charge the device in more or less 45 minutes. Also, I have tried the USB Type-C port with a Nexus 6P (luckily i have a friend at University that has it), and it does seem to work as good as with the Original Nexus Charger.
Battery Life
Battery Life is simply amazing, it is hard to discharge the power bank completely in less than 1 week, especially if you need to charge only one smartphone that doesn’t come with a large battery. There is always some juice left even if there is only one LED lighted up (so it means less than 25% of available battery). When the battery level is extremely low, the LED starts to blink but I managed to charge a Sony PSVita (2210 mAh) nearly completely after the LED started to blink so this is pretty good.
This is a GIF that i made, unfortunately XDA doesn't support GIF playback so i had to convert and upload it on YouTube.
Efficiency
I made some tests using an USB Tester with the included USB Cable (short variant), as you can see it is able to provide 1.9A without major issues (maybe a bit low voltage, but using another cable it is higher). I don’t have a 3A resistor so I won’t be able to show you a test under higher load, but I have stressed both USB ports at the same time and I can confirm you that it is able to handle more than 3A load without any issue at all.
Charging
I’m using a RAVPower Turbo+ QC 3.0 Charger to charge the battery. (Best Combo)
I left the battery connected to the charger at 23:30, and when I got up (08:15) the battery was fully charged and cold, so I can say that it took more or less 8 hours (probably 7 hours, because both battery & charger were cold) to charge completely. Remember that even if Qualcomm Quick Charge makes the whole charging process faster, it is also temperature controlled so if battery gets hot current output gets reduced to cool down the battery without causing damage.
Power Output seems to be extremely efficient here, voltage is much higher at 2A than using the Battery.
It is a bit heavy, but extremely powerful and feels pretty well made.
This is the best charger i have ever tried. I can recommend it even if you have to charge other kind of devices.
Conclusions
This battery is one of the most complete available on the market, so if you need a full-optional and powerful Power Bank, then this is the right choice. I know, it isn’t easy to carry everywhere because it doesn’t fit in your pocket, so this is something useful if you carry a bag with you or if you have anything else where to fit the battery, but actually no other power banks offer so many USB ports, Quick Charge 3.0 support and Quality Battery Cells inside.
If you don’t need Quick Charge 3.0 support, I recommend you to get the QC 2.0 version to save some money. Also, i recommend you to get also the RAVPower Turbo+ QC 3.0 Charger (or Turbo QC 2.0) for best results.
I’ll add an additional review about reliability in 6 months more or less to let you know if I find any kind of issue during full-term usage.

20100 mah = 20100x3.7= 74Watt hours
If it was fully charged in 7 hours, thats around 12W going into the power bank. This is slow.
I would have expected it to charge full within 5 hours which would be at least 15W or more going in.
The charger i have and what i find curious about it is if you look at the specs they are actually QC2.But it says QC3.0/2.0 on the charging port. Not on qualcom's list of certified QC3 chargers.
if you look at the battery specs they are QC3 and is on qualcom's list as certified QC3.
Would be good if you can get a double digit meter so we can see how much power that charger is actually putting into the pack.
Also have you been able to test with a QC3 phone and measure how long it took.

It is something that i'll do as soon as possible.
Also, remember that you can't completely base your opinion on technical specs, because there are many other factors such as Temperature that might increase charging times.

Cool, quote or @ me when you do.
If you see here the times, with qc2 charger its 5.5 hrs.
With QC3 it should be better. Why your ravpower charger cannot do it ?
Would also request you to upgrade your usb meter and re-test with this power bank and charger.

I do not speak Italian but i understood he is saying that meter works with xiaomi mi5 and qc3
PS: best of luck to your Azzuri tonight
Real Battery Capacity after 3 Months of Usage. Consider that the battery wasn't completely dead, with flashing low-battery leds, this might be a bit lower.
I haven't measured battery charging times this time because i had to use the Standard 5V charger in order to get the correct mAh value, next recharge will be made using the QC Charger.
Thanks for your post

Looks pretty close to stated capacity.
Can your power meter show two digits? Charge times is not so clear.
Cool review. It is useful . Have you found it is similar to Anker core 20100?

This is a review of Anker Astro E7 25600 mAh external battery. http://www.amazon.com/Ultra-High-Capacity-25600mAh-External-Technology/dp/B00M3073L4/
About a week ago we were expecting a big snow storm. Thank God it turned out to be nothing, but in preparation I went through my usual routine of getting extra food and water, getting extra gasoline for our generator, and.... making sure all my Anker batteries are charged up! I often talk about external batteries as a boost source on the go when you want to have something small and pocket friendly. But if you want to be prepared for any emergency or planning to be away from a power source for days - you want to have a battery with a big enough capacity, and that's what 2nd gen Astro E7 delivers with its enormous 25600 mAh. Here is more about it.
After reviewing so many different Anker batteries, I'm already used to their environmentally friendly packaging and typical accessories of a high quality usb to micro-usb cable and storage pouch. But it's always a surprise to see how big the battery turns out to be based on the advertised capacity. You have to realize that increased capacity comes at a price of increased size and additional weight. It's a simple math - higher capacity means more internal battery cells. That is why I never trust some of the budget ebay and other retailers small battery bricks claiming 20k mAh in a footprint of 10k battery. Out of the box, you will definitely feel the weight of E7 at almost 16oz (450g), but it's still manageable thanks to its slick rectangular shape with rounded edges which is easy to handle. With a dimensions of 166 × 80 × 22mm (6.5 × 3.1 × 0.9in) it can actually slip into your front pocket or cargo pants side pocket without a problem, though it will be noticeable. The whole intent of this battery is not to be a small portable back up charger but rather a portable charging power station to give your phones and tablets a boost with up to10 combined charges.
The design is similar to their other 2nd gen E-models, just scaled up in size. You still get a slick piano finish plastic body, very sturdy, no flex. Also a power button on the side to turn the battery on/off, though I found it starts charging automatically as soon as it detects attached device. Another function of power button is to turn built-in white LED by holding and pressing this button. LED functionality is a welcome bonus, especially in emergency situation to use as a portable flashlight or to lit up usb ports so you can connect the cable in the dark. The top of the battery has 4 LEDs to indicate remaining power or to display charging power. These indicate 25% per LED, not as accurate as a regular Astro line with 10-led indicators, but for bulk charging this should be sufficient. I also prefer led indicators over some other batteries that use LCD display which drains the battery. And speaking for that, I can confirm that all of my 2nd gen Anker batteries hold the charge for multiple months when not in use.
E7 model comes with one micro-usb input charging port and 3 full size usb power output ports, each equipped with PowerIQ feature that automatically adjusts current supply per attached device requirement. So if you have an old Android phone, it will source only 1A, while newer phones will get 2A, and your latest iPad will be charging at full 2.4A. Just have to keep in mind that a total combined current can't exceed 4A. Another very important feature is 2A charging input. With a capacity of 25,600 mAh it will take you over a day to charge this battery from empty using a typical 1A charger. Here with 2A wall charger you can juice it up to 100% in approximately 12-13 hours. Also, it's very important to keep in mind that with any battery you have to take into account the convergence efficiency since you are going between 3.7V cells and 5V usb interface. Anker converters are usually very efficient and deliver only 10-12% drop, bringing it closer to 90% efficiency. In comparison, a lot of other batteries are struggling around 80%. With Anker E7 battery you can get about 23,000 mAh of the actual charging capacity.
Overall, I'm always impressed with power products from Anker and consider their external batteries to be among the best. You don't have to take my word for it or to tell me that I'm biased, just search our community for all the positive feedback or look on Amazon where it's #1 best seller in every category with thousands of 5-star reviews. The combination of top quality LG battery cells, durable design, super fast input charging without a need to use proprietary connectors (just a standard micro-usb), bonus of LED light, high efficiency and huge storage capacity, and their 18-months warranty and excellent support - makes this battery my top recommendation, despite a price tag of $80 (just factor in combined cost of smaller capacity batteries).

Hi,
Great review. I have the same pack at home. I charge my oneplus-two with it. Normally I should get at least 7 charges out of it but I can get only 4 or sometimes 5 at max. Do you have this too?
@CounterC Not really sure what you mean. You used exactly the same battery with the same capacity to charge the same phone 7 times, and not it's only 4-5 times? If that is a case, maybe your phone is discharging too fast while you charging it up, so you get less # charges. Or maybe you were using a different phone or different charger before when you got 7 full charges? To make a true A/B comparison, everything has to be equal

I have a OnePlus 2 that has 3300mah battery.
So in theory I should be able to charge the device 7,75 times. Unfortunately I get only half of the charges. I explained this to Anker and they just refunded me so now I have a free battery pack [emoji1] [emoji1]. You also see this behavior with your pack?

It doesn't work like a simple math. Just because battery has 25600 mAh capacity it doesn't mean it will charge your 3300 mAh battery 7 times. This capacity is based on the cells inside, and you have 25.6 Ah at 3.7V. You usb charging port is rated at 5V, and there is a converter at the output from 3.7V to 5V from your battery. Your phone micro-usb port is 5V but internal battery is probably 3.8V, so you have to convert it internally back from 5V to 3.8V. Every time you do the conversion, you loose power due to efficiency. So by the time it gets to charging your phone battery with external battery, you loose a chunk of capacity where instead of 7 times you can charge only 5-6 times. Now, the charging cable is another bottleneck. If you have a thick high quality usb to micro-usb cable with good connector, there is less lose. But if it's an older cable or connector is loose, you - will loose more charging capacity, down to 4-5 charges which you are seeing now.
So, enjoy your free battery
This is a review of Aukey Quick Charge 2.0 (Qualcomm certified) wall charger. http://www.amazon.com/dp/B00QEX83LA/ ($16.99), product page: http://www.aukey.com/product/pau28-qualcomm-quick-charge-usb-adapter
This is going to be a quick review since we are talking about a wall charger, though it's not an ordinary one but rather featuring Qualcomm Quick Charge 2.0 technology implemented in our Galaxy Note 4 as part of an adaptive fast charging. I see more of these wall chargers starting to pop up, but want to be sure you guys/gals don't fall for ebay scams and rather go with a trusted brand names that has been around for awhile and offer a solid warranty and tech support. The idea of Quick Charger 2.0 tech is to implement a higher voltage adaptive charging (at 9V or 12V instead of typical 5V) to accelerate charging of your smartphone battery. A number of new phones and tablets can take advantage of this adaptive fast charging already, while this product is also backward compatible with older phones to charge at 5V. Furthermore, you have to keep in mind that max current rating doesn't mean that your older phone will be drawing more current, it shouldn't sink more than it's maximum current rating. Therefore this particular charger from Aukey is universal to work with newer phones and also backward compatible with older ones, even those that can't take advantage of 2A charging.
The product itself arrived in a small environmentally safe box with just a charger and user manual. It would have been good if they would include usb to micro-usb cable, but I guess Aukey assumed that we already have plenty of those laying around. Just please keep in mind, for a higher voltage/current fast charging make sure to use a higher quality thicker usb cables. Thinner "data" usb cable are not intended for high current, and as a matter of fact can current-limit charge resulting in overheating.
Overall, this Aukey Quick Charger 2.0 performed exactly the same as Samsung Galaxy Note 4 original fast charger, which makes it a great replacement or a second set to keep in your office or when traveling. The build quality is good, feels solid in my hand, didn't overheat - no complaints here!

Thanks a lot for the review. I also bought two along with a pack of 4 usb cables from Aukey for 32 euros and its working great. I would never pay 35 euros for a single charger when all quickcharge 2.0 certified chargers work the same
Vectron, another great review. Thank You.
What glass screen protector are you currently using?
What a great review. even though there is no cable included
Priced dropped to $14.99.
The Samsung fast charger looks sleeker
It does but it costs 3 times more

Qualcomm quick charging 2, does that mean that it only works for the snapdragon version? Or would it work on the exynos version (N910C) too?
NICE!

it will "work" in the same way any charger for the exynos will, as a 5.3V 2A charger. It will not Quick charge. so you are probably looking at ~1:45-2hrs to charge vs ~1:15-1:30 for a full charge on the stock battery.
Quick charge doesn't really do anything for the extended batteries since there is a limitation (firmware maybe) of 3320 MAH after that the charger stops charging. So quick charging has to be disabled to charge the larger batteries. Quick charging worked perfectly with an anker 6400 battery that I now have. Apparently this is a zerolemon limitation
I have this charger as well. I do think it charges slightly faster that the stock charger although that could be wishful thinking on my part. There really is no way to compare them since they both charge so quickly (normally right around an hour from 20%-full) so a minute or two could be simply what the phone is doing in the background.
I also have the tenergy, anker, verizon quick chargers and with all of them the charge is very fast.
How hot does it get? I had a 2A charger that sometimes got too hot to touch... at some point it died.

Mine dosent. The phone does a little, especially during the first half of the battery
I just bought a 5-port version (with 4 Ai ports and 1 QuickCharge port) http://www.amazon.com/Qualcomm-Certified-Aukey-Charging-Included/dp/B00UV4HCL0
OP's review covered the QuickCharge port. How about the other 4 ports? Does the Ai really work?
Thanks!
Hmm... I've received mine today with one USB port, but it's strange that micro usb don't go all the way to my Note 4 F version, and don't seem to charge fast as well? When Samsung charger is plug in there is a notification "Fast charger connected" but with Aukey there is no such information. Is it possible that I've bought fake/faulty one? When plugged my Note 4 to Aukey charger I didn't see any changes of battery percentage (when plug in was 8%) after about 5min was the same with Samsung went from 8% to about 11%. Any ideas?
I have the aukey one with three USB ports. When I plug on the fast charge, the screen does say fast charge.

So in my case I've got fake one or faulty one. I'll post pictures how my charger look like.

This is a Review of Anker PowerCore+ Mini 3350 mAh �lipstick� external battery. http://www.ianker.com/product/A1105011.
When it comes to external batteries, bigger capacity doesn�t necessary mean a better battery. Yes, we always look for the best price/performance/capacity ratio, but with batteries you need to figure out the capacity per need ratio. When you are at home and need a backup battery, get the largest capacity you can find � there is no need to drag it around so it could be as heavy as it comes. When you are traveling, maybe a compromise of a smaller capacity in exchange for a lighter weight is the better way to go. But for everyday portable use where you need an emergency backup � the smallest footprint with the largest capacity you can find is what you should be looking for. Even so Astro is already small and portable, it will be hard to beat Anker�s latest �lipstick� PowerCore+ Mini with 3,350 mAh.
I know some will say capacity of only 3,350 mAh?!? We get spoiled quickly with 10,000 mAh or 20,000 mAh external batteries, but when you take a look at this tiny 95 x 23 x 23mm (3.7 x 0.9 x 0.9in) size lipstick cylinder in a quality aluminum drop-tested shell with a weight of only 3oz � you will really appreciate size/capacity ratio. On top of that, it comes with Anker�s typical drawstring small storage pouch and a quality usb to micro usb cable. And since it�s available in a variety of colors, including some colorful pink and blue finishes, this battery can also be used as a �fashionable� accessory for the ladies.
The design itself is very minimalistic and elegant. I already mentioned about aluminum shell finish which feels very solid in your hand and gives you extra peace of mind if you accidentally drop it. The shell covers the entire cylinder in one solid piece, leaving only the top open where you have full size USB port to connect cable to your phone or tablet, micro USB port to charge this battery, and a small led/power button. To display the charging capacity, led has 3 colors to indicate: green 50%-100%, yellow 20%-50%, and red 5%-20%. It�s obviously not as accurate as Astro�s 10-led indicator with 10% increments, but considering this small footprint � it works fine. Plus keep in mind, most of the time you will probably get one or two full charges from this battery, so accuracy is not as important.
In terms of performance, Anker mentions it uses a premium Panasonic cell which is always a plus. The battery itself has a rather high efficiency of almost 92% (confirmed) which means you still get a solid 3,080 mAh of charging from this battery after internal 5V conversion through usb port. Most of the other lipstick batteries are typically in 80% efficiency range due to less efficient converters. The charging of the battery itself will not be lighting fast since input port is 5V at 1A, so expect a little over 3hrs of charging from empty. The ext charging port is only able to supply 1A of output power at 5V, though I actually confirmed it to provide 1.2A with my Note 4. It does offer PowerIQ intelligent charging current adjustment, but it doesn't matter since you are not going between 1A, 2A, or 2.4A charging speed. Most likely it will run around 1A-1.2A which is OK for emergency charging when you are on a go.
Overall, if you are looking for a super portable external battery for your phone or tablet, and need the smallest compact footprint to put it in your shirt pocket or a purse without adding too much weight, and still want to have enough capacity for emergency fast charging � this new Anker PowerCore+ Mini might be the one for you. 3,350 mAh is a pretty good capacity for on-the-go emergency charging, and if you factor in high efficiency, quality build with aluminum solid shell, included travel pouch and usb cable, and Anker�s 18-months warranty � this is one cool gadget to keep with you in a pocket for under $20.
Here are the pictures.

I have two of these, neither achieves anywhere near that efficiency with either Galaxy S4 or Note 5, with the cable provided, which the phone entirely turned off.
Both provide around 2300-2500mAh effectively, that is efficiency net of battery, powercircuit, cable and phone charging circuit losses, or around 70%.
Anker officially also confirms an efficiency of around 70% or, quote: "an almost one full charge to a Galaxy S6" (< 2550mAh), respectively.
So I am not just making this up. I tested this with an inline USB meter as well as with Battery Monitor Widget.
In their English that is almost one full charge for my Galaxy S4, or about 3/4 charge for my Note 5 (phones off while charging, duh!)
This is still a handy little thing to have, but Anker is very shy to openly say how efficient their devices are. All about that sale and Amazon tags after all.

Are you sure you are not talking about PowerCore Mini, rather than their latest PowerCore+ Mini? "+" is an updated version.
Yes, Anker PowerCore+ mini 3350mAh. I got one for my Note 5 thinking should be a full charge, but wasn't the case.
After that, I went to the reviews on Amazon and also http://www.ianker.com/support/A1104041, they actually say it's 70-80%, mine was more around 70-75% with the Note 5 off while charging.
It's not Anker-specific though, Anker is doing relatively well, Aukey 5000mAh is only around 65%...
Also, either way, for 10 GBP it's really not bad. Just love how 90% of customers incl myself buy something without knowing better b/c it's all in the fineprint.
The quote from ianker website:
The efficiency of this powercore is around 70%-80%. The internal circuit board is 92% efficient, accounting for power lost through circuit heat and voltage conversion, which is up to 5% above the industry average. Energy is also lost within the charging cable and the device being charged (approximately 15-20%). Additionally, the efficiency can be affected by the cable length and the age of the device being charged.
Where the efficiency of conversion under ideal condition is over 90%. They trying to be conservative saying overall it could drop to 70%-80% depending on your phone model, internal battery age, and the most important - cables which can overheat (if they are cheap thin with loose connection). In one of my reviews testing battery charge monitor and different cables I demonstrated variation of different cables which could affect efficiency as well.
But anyway. This lipstick battery is for emergency boost (not a reliable full charge, but a boost to keep you afloat ) and doesn't even allow a fast charging. If you really need a backup, get a higher capacity more advanced battery from Anker with PowerIQ chip.

And what about a cable supplied with this device?
Bought one yesterday, did 2 full charge-uncharge cycles:
1) Razr Maxx XT910 +35% (65->91%) and Nexus 9 +12% (27->40%)
2) Nexus 9 +33% (27->60%). Charging current was 1.25A.
A chinese device showed that Anker got about 3200ma*h from power supply. And it delivered about 2200 ma*h to Nexus 9, which really looks like 33% of its 6700mah battery.

I have tested 3 of these.....
multiple charge/discharge cycles gave similar results....
My usb monitor shows. for full discharge (100-0)%....
Capacity: 1.657Ah ( @5v ) , 8.622Wh := 2.23Ah (@3.7v) ...or 2230mah
This is almost identical to what you got.
Charging(from usb power -->> anker mini ) : 15.858Wh = 3170mah .....from (0-100)%
also similar to what you got..... confirmation of your results ( and mine).
Yes, it's only useful as a partial boost......

This is a review of Anker PowerCore+ 20100 mAh USB/USB-C external battery. http://www.ianker.com/product/A1371011, also available on Amazon http://www.amazon.com/gp/product/B014ZO46LK/
It has been awhile since I reviewed external batteries because a lot of these new product releases became redundant. There was nothing new or exciting until QC2.0 was introduced. When you look on-line, there are multiple dozens of unknown re-branded external batteries, while only a handful of trusted manufacturers who stand behind their product with quality control, extended warranty, and adequate tech support. I always hold Anker in high regard and was a bit surprised they didn't jump on QC2.0 bandwagon right away. But now I quickly realized they were aiming higher, at the new USB-C standard.
USB-C topic has been a buzz for a while now, and we are finally starting to see more devices supporting it. What makes it stand out is the reversible connector which you can plug in either way by flipping it. It resembles micro-usb, but adds symmetrical layout which you can flip. No more trying to jam the connector upside down in the dark. Plus, USB-C will support 1.5A and 3A at 5V, depending on the device sinking the current. And speaking of devices, there are already a number of those that support USB-C standard, including 2015 MacBook, Google's Chromebook Pixel, and upcoming Nexus 5x and Nexus 6P. I personally don't have any of these devices yet, but still was excited to take a look into this next gen Anker external battery.
Unboxing.
Arrived in a nice sturdy cardboard box, I noticed that Anker changed their packaging. Still environmentally safe and without any non-recyclable plastic, but now with a little less generic look. There is no battery image on the cover, but the back has a clear message of "The Future of USB Connectivity has Arrived", listing different USB-C product solutions offered by Anker.
Inside of the box you have a partitioned area for the battery and accessories box.

Accessories.
Beside the actual battery, included accessories are USB to micro-USB cable, USB to USB-C cable, and a storage pouch. Considering battery enclosure is all metal (aluminum), storage pouch is always a plus even while using the battery, so it creates an extra friction with a surface or keeps surface away from scratches. Now with support of USB-C, you have an option to charge other devices supporting this connector as well as using this cable to charge the battery. My only comment here, I wish two USB-C cables where included since you will always need to use one for charging of the battery because input is usb-c, and you need another one to charge devices with usb-c. But I'm sure it won't be a problem to buy a spare cable.
Design.
Considering 20100 mAh capacity of this new PowerCore+ battery, there shouldn't be any expectations of portable design. The battery dimensions are 185mm x 60mm x 23mm with a heft of 460g! The weight comes from the battery cells that hold this enormous charging capacity, and Anker usually open about using premium Panasonic cells. What I like about this battery, despite a noticeable weight, the design is very slim and elongated, making handling of this battery very easy with a comfortable grip. And even so the body is all aluminum shell, it feels very solid with no flex due to a reinforcement layer underneath. Also, the shell provides a good heat dissipation which enhances the efficiency of the battery.
The usb ports are located on one side where you have 2x full size USB Power IQ output ports, and one USB-C input port. Input power supports 2.4A @5V charging which can also accept QC2.0 from corresponding wall charger. Keep mind, you have to use usb-to-usb-C cable to charge this battery, thus my comment about having a spare one. The output USB ports do NOT support QC2.0, but they can source up to 2.4A at 5V. As a matter of fact, combined outputs are rated at 6A.
The only other control is a combined Power button with LED meter wheel, or as Anker refers to LED Power Wheel. In the last few years LED meter indicators undergone quite an evolution. Everybody was using 4-LED indicators for 25% increment charging/capacity. Then, some went for 5-LEDs to have a more "granular" 20% increment. There was also some with LCD display showing the actual percentage, but that added a drain to the battery itself. Anker was among first with 10-led circle indicator, but their designs required shaking to turn the power on or bringing up LED status. This new battery has a round power push-button with 10-led segments built into it - the BEST design to date. You don't need to shake anything, push button has a nice tactile response, and 10 bright LED dots give you an excellent visual feedback of the charging status or the battery capacity in more accurate 10% increments.
Charging.
Charging of the battery itself is very straight forward, and you have to keep in mind that large capacity takes a while to get fully charged. Even so you can use your regular 2A wall charger, it will take you half a day to charge it up. With QC2.0 wall charger, you can re-charge PowerCore+ itself in about 5 hours.
When it comes to charging of your devices, smartphone or tablet or laptops supporting usb-c, the current draw is dependent on your device and PowerIQ chip will determine the optimal charging speed. For example, my Note 4 can be charged at 2A rate, but connected to this battery it was only drawing 1.65A which is still fast enough.
The efficiency of the battery is over 90% meaning you will get over 18100 mAh, actually closer to 19000 mAh. The battery is very efficient, and it also has an advanced surge protection and short circuit prevention, especially important when charging high current usb-c devices.
Conclusion.
Even if you don't take into consideration USB-C support, this is one high quality and high capacity battery at a very reasonable price with 18-month of warranty and bulletproof build quality. Quite amazing that about a year ago 20k mAh capacity batteries used to be close to $100, while this PowerCore+ is under $60. The only real negative here is that battery can't charge other devices at QC2.0 quick charge rate. Other than that, you are getting an all aluminum shell construction, USB-C input/output port support, advanced power button with 10-led meter, rapid charging of the battery itself, 2 output ports supporting up to 6A of current and being compatible with both standards USB and USB-C, and a huge 20k mAh capacity. Definitely recommend this PowerCore+ if you want to future-proof your external battery.
A great review of this product. I would definitely look at it as an option in the future.
"The output USB ports do NOT support QC2.0, but they can source up to 2.4A at 5V. As a matter of fact, combined outputs are rated at 6A."
I can't recall can someone tell me how much quicker the quick charge 2.0 standard is compared to this 2.4A at 5V please?

QC2.0 works at higher voltage. So for example while I was able to charge my Note 4 with a regular charger at 1.7A @5.1V, QC2.0 charges it at 1.6A @6.6V. We are not talking about significantly faster but noticeably enough.
Why do we need to buy extra cables?

You don't need to buy any extra cables, everything is included. I'm just saying it would be convenient to use one cable to charge the battery itself, and another one to charge your devices. Just less wear on a cable
Someone should test if it can recharged at 2.4 amps (Input side) and it definitely will not support 3A at 5V (Output side) !
It's better to stay away from this item, as Anker will soon release the real USB-C PD charger. The real USB-C spec should support 3A at 5V both Input & Output side.

What makes you say it "definitely will not support" 3A @5V? Did you test it with the latest Nexus or MacBook using charging meter to confirm that? I only mentioned in my review they are compliant with USB-C standard because Anker works directly with a lot of manufacturers and they have access to all the latest chipsets.
I don't want to mislead anybody and honestly tell you what I can and can't test, thus relying on you guys to reply back to share your own experience to either confirm or not if there is a problem. If you make a bold statement that it "will not" do something, please support it with your own test results. Ok bud?
@vectron : Because Anker says @ Amazon "Capable of charging the new MacBook at 5V/2.4A" , so why should we believe it will charge 3A at 5V
I have tested Anker 60W and the result was UNDERPERFORMED and we have discussed it before

The charger is a source which can supply up to the max rated amount of the current. It's up to a target, your smartphone or tablet or laptop, to sink (draw) this amount of current. My Note 4 is rated at 2A but can only draw 1.7A. Not the issue of the charger, but my phone.
Like I said, the only way to find out is for someone to test it. And if a vendor makes false claims, nobody going to buy from them. So far, Anker has been doing pretty good

You're right, the device only draws what is required.
The problem is looks like the Anker 60W is not compatible with Xiaomi Power banks, it could not charged at 2 amps (tested). Let see when my PowerPort 4 arrives.

Choetech 10400 QC 3.0 Enabled Battery Pack:
Overview
Choetech took their old QC 2.0 battery and made some improvements to it while also adding QC 3.0.
Ports/Charging:
There are a variety of ports offered on this battery which serve different functions. First the battery can be charged on of two ways: you can either use a microUSB cable (like the one included in the box), or a lightning cable if you happen to also have an Apple device. Both cables will allow the battery to be charged at 5V/2.4A; however, I found the battery charges via QC 2.0. I tested it via my multimeter which show the battery drawing ~9V/1.8A which is closer to 16.2 W of power. I’m not sure why the battery doesn’t list this as an input because it certainly takes all of the power.
On the output side you are given the option of using 2 USB-A standard ports. One of these ports will charge at 5V/1A which is also known as QC 1.0, while the second one charges via QC 3.0. The voltage range is variable as is the current. The ranges for the QC 3.0 port are: 5V/3A (15W), 9V/2A (18W), 12V 1.5A (15W). All of these outputs are consistent with the QC 3.0 standard which allows the voltage to step in smaller increments thus reducing the overall heat and increasing charging efficiency.
Design/Build Quality:
This battery has a very nice, solid aluminum housing that really makes it feel nice. The top/bottom edges are chamfered, while the sides are black anodized aluminum. This is the perfect pairing for the HTC 10 given its nice chamfered edge, and similar aluminum construction. I have another Choetech battery pack that is equally well made and feels like a tank. I don’t foresee this battery buckling under normal use, or even some drops given how well made it feels.
To use the battery, you first need to hit the power button that in turn lights up a series of 4 bright LED’s. These LED’s will indicate the current charge left on the battery while also looking great. When you are charging the battery pack the LED indicating its current level of charge will blink as an indication of how much power is currently store in the battery.

Charging Ports:
Here is breakdown of the voltages/rates the battery can be charged at:
Output: 5V/1A (5W)
QC 3.0 Port: 5V/3A (15W), 9V/2A (18W), 12V/1.25A (15W) [/SIZE]
Battery I/O Rating Pictures
Given the battery’s two output ports, you will be able to charge two devices simultaneously, although I would only use it to charge one at a time personally.
Overall This is a great small QC 3.0 enabled battery pack that will keep everything working on the go. I own battery packs from EasyACC, Choetech, Aukey, and Anker, but this one is still one of my favorites for what it offers. I plan on using this battery to charge my HTC 10 while at school, and on the go in general.
Nice review, I've done a similar thing on amazon, also found the charger to be great. I did a quick charging test and it was averaging around 1500mA, whereas the htc one main plugs charger was 1600mA, so to charge that close to a main plugs socket is great. Specially for a portable charger where you want it charging fast!

This battery will output the rated (18W) if the phone can handle that much current. I posted a picture in my review using a multimeter to measure the power (16.8W at the moment I took the picture). I don't know what the phones peak input current is, but I know it's higher than than S7 Edges 15.03W input, and Neuxs 6P's 15W. I've seen similar ranges of 15-17W using the stock HTC charger which means this battery is outputting the proper current for the phone to charge as fast as it possible can via the QC 3.0 port.

If you account for the efficiency external batteries have (not very high due to heat losses) the 2 full charges is about right in my experience.

Yup when looking at mah of portable batteries I always take off about 30%. Assuming it's good quality that about what you get. I. E in this case 10400mah you get about 7000mah actually usable. Obviously that goes down with time too.

Plus when quick charging you could lose some of the ~7000 you might expect, regardless of that I still find it to work as well as my other 1000mAh battery packs.
Things I miss in your review:
How much does it cost, and how are competitive products placed?
How long does it take to charge the Battery with a QC2.0 Charger?
How much is really inside?
You'd have to use a constant 1.5A load and check How long it lasts... ?
Except from that. Nice review Thanks.
Choetech has stated they're using Samsung Li-Ion cells so they're likely these. I'll crack open mine when I receive it, haven't ordered it yet.

-26H is the successor to -26F

I personally have these -26H's inside my 4x18650 5V2A power bank case.
They're great cells for indoor use and low current draw (per cell) use.
They'll happily dump over 90% of the specified Whours even at a full 5A discharge. (which is 2600*3.63/1000=9.44Wh)
At a more sane discharge current of 1A/2A they'll be able to provide ~ 99/96% of the specified Whours.
So how much is really inside? Spec sheet says 10200mAh's assuming 0.2C discharge and 2.75V cut-off.
In practice? ~10200-10600mAh's depending on the discharge current. (this is of course fresh cells, capacity will drop over time)
This of course does not take into account the power loss which occurs when you boost the voltage up.
Assuming a nice, above average 90% efficiency inside the power bank you'd be looking at ~9200mAh's.
Then taking into account the voltage stepdown happening inside the phone, let's assume 90% efficiency again and we'd be looking at ~8150mAh's.
Aaand then taking into account the cable loss (- connector losses), let's assume you have an average 26AWG 1 meter cable and you transfer 18W of power at 9V2A, loss is 6%.
We're down to ~7550mAh's.
Saying it can charge a 3000mAh battery twice plays nice with that calculation.
One thing to note though and like I said, great for indoor use but if you look at the spec sheet, you can see the capacity vs temperature table.

tl;dr if you wish to extract every little ounce of power you can from these cells (or this power bank)
if you go hiking in really cold weather, make sure it stays close to room temp (25C), so not in the outermost compartment of your backpack but neither touching your body which could then warm it up higher than room temp - no es bueno.
if it's a really warm, sunny summer day and you go have a beer outside sitting in the porch, don't leave the power bank in direct sunlight, place it in shade instead
This is pretty much business as usual and has to do with the design of the cell and cathode material used.
Cells [like the -26H] intended for laptops, power banks etc. are going to have different discharge characteristics compared to cells [like INR18650-25R] intended for electric vehicles, power tools and so on.
So it's good that the power bank has an aluminium chassis. It's going to be able to dump some of that heat generated by the boost circuitry in to the air and so on and so forth.
The cells themselves won't really heat up that much. You know, there's 4 of them in there and they are in parallel = current load is being split pretty much equally.
At 3V under load which is pretty close to fully discharged (cut-off = ~2.75V), if the power bank circuitry is prodiving 18 watts of power and drawing 21.6 watts (18+20%) from the 1S4P battery pack because of inefficiencies, it would still be just 7.2A of current total and 1.8A per cell.
Well within the capabilities of these Samsung cells and so low power wise per cell they're not heating up much.
I recently added this one to my arsenal and now prefer it over others I have. I can charge it off anyone's charger i'm with on longer trips so cable management is nill. Love the fact you can tell it's in qc mode versus normal charge mode.
Just recently got this power bank for my hTc 10 - as from my experience 10Ah looks impressive on the computer screen - but in real life we actually need 20Ah backup battery .. ?
Spoiler
And it states that output is 12V x 1.5A what actually implies 18W... ?

Well, not exactly nil, right? You can charge from micro-usb or from lightning, which is a great addition, but you can't actually charge from the cable you're most likely to be carrying with your HTC 10, which is a USB C cable, right? I looked at the description on Amazon, and thought that was an interesting omission.

It can be charged via a microusb cable that is included. Since they are as common as can be I don't see how that would be an issue. I have piles of them laying around, spare one in my car etc.. I know it's not ideal to have more than one type of cable, but I use them to charge my S7 Edge, Bose QC 20's , LG Tone Platinum's etc.. that's why I personally have them just about everywhere. I also have a time of Type-C, C-C/A-C cables because of my Nexus 6P. Ideally I would like 4 type c poets for in/out but no one makes anything close yet.

I never suggested it would be hard to find a cable to charge the battery pack.
But dottat wrote that cable management issues were nil, so I was merely pointing out that for those of us with HTC 10s that really isn't quite the case, since if we want to travel with a single cable, the single cable we are going to travel with -- a USB C cable -- can't charge the battery. This means bringing two cables, at a minimum.
This was not a huge complaint or indictment of the product. I was just making a point. The product would be even better if it could charge via a USB C cable.

I completely agree, unfortunately there are only a handful of battery packs that support QC 3.0 and even fewer that offer Type-C (if any yet) on top of that. The interesting part is their QC 2.0 version has a Type-C port to charge the battery along side the microusb. I'm not sure why they changed that (maybe to appeal to a larger crowd), but it's odd nonetheless. I can post a picture of it later today since its 0103 right now so the lighting wouldn't be ideal to see it.

But within a large company someone is definitely with iPhone - what somehow suggests carrying one more cable.. ?
I opted to carry my original hTc 10 Type C cable and a small interface which converts Type C into the lightning connector.. ?

They make one that charges via Type-C as I mentioned earlier; however, it uses QC 2.0 as opposed to QC 3.0
Has anyone compared this Choetech 10400 QC3 (currently unavailable on Amazon) with the Anker 20000 QC3? Pros? Cons?
