Keeping your phone charged when you're out and about isn't always easy so it's no wonder portable chargers and power banks are such a popular investment.
I was not sure exactly of the prices before but I know they were not far off this, Super Sneeky!!! Any recommendations on power banks people???
I prefer mi power bank form xiaomi that was a good quality

I know xiaomi power bank is good.But it is too hard to purchase origianl
If you are from US, Anker power banks have no competition and still #1 rated/selling product on amazon.

I myself now using xiaomi power bank, well. I cannot recognize whether it is the original one though it is declared to be. If I have to get another power bank, this time I'd prefer a solar one. Solar charger is more convenient to use. Can be both charged with USB adapter and solar energy. Some are even water-resistant. You can consider that as well.:laugh:

I would not recommend pure solar chargers. Even if you get it in a direct sunlight, due to a small surface area with solar cells you will not get higher charging power than 0.5A which is a joke comparing to most of the smartphones and tablets requiring 2A of charging. I even tried large solar panel folding chargers and was never able to get 1A of charging current out of them. Plus, you have to be in a direct sun light and open space without any shade.
If you have one of those regular external batteries with a solar charger on top of it, so you can charger it either from a sun or from AC wall adapter, it's better since you can store a charge into the internal battery. But again, it will take you MANY hours to fill it up because it chargers as painfully slow rate.
Just for the reference, if you are using your phone or even idle with apps running in the background, you can be easily discharging at higher rate than 0.5A that your solar charger will provide.
Bottom line, solar chargers are a nice to keep your calculator running For a modern smartphone or a tablet with 3000-5000mAh internal battery - it will not be useful.

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
I don't know about you but I was surprised when I saw for the first time rugged power bank.
Obviously now it's time for other gadgets like power banks to became resistant like Borg
From what I can see EasyAcc is the first company which has introduced rugged power bank with codename TP20000-BG.
IP rating
EasyAcc TP20000-BG have IP 67 rating so in other words it is waterproof, dustproof and shockproof.
So it can be underwater for 30 minutes maximum 1 meter. In my opinion these kind of power bank are
ideal for adventurers, athletes. Also for example you can easily ride the bike without thinking about whether power bank might fall in mud or something similar.
Design and build
As you can see on photos these power bank looks tough and in reality it is really strong because it is made
from high quality industrial-grade plastic, so in other words it is prepared for every potential danger. Also according
to the company EasyAcc TP20000-BG has CE, FCC, RoHS certificates. I think mostly people will like these kind of army design,
also in my opinion it looks really cool. All ports including buttons are located on the front side, it has two available USB ports
for charging and one micro USB port for charging itself. There is also a led light which is actually really strong and it can be used as lamp.
Fast charging
These days fast charging is indispensable function because for many reasons, but of course the main reason is definitely
faster charging and less time to get fully charged phone or tablet. Depending on what you will charge this power bank
can charge 5V 2.4A max. As I said earlier it has two USB ports for charging and you can charge at the same time two different or the same devices.
Equally these power bank have huge capacity of 20000mAh and because of that they have allowed also fast charging for
itself and he can receive maximum 5V 2A. So if you will use maximum charging input then it needs approximately 12 hours to get fully charge from zero.
Battery capacity
EasyAcc TP20000-BG has 20000 mAh capacity which allows you in theory charge seven times Galaxy S6 according to
company. I think they did not exaggerated because according to my tests it has approximately 19000 mAh which is definitely fine.
Conclusion
In my opinion these power bank can satisfy almost all requirements because the battery has high-capacity,
the case is made from high quality plastic and it has IP 67 rating and because of that if these waterproof,
dustproof and shockproof which is definitely an advantage. For more information you can visit Majordroid or their official site.
So I'm in my junior year of electrical engineering and seeing the incredible things done with smartphones is something I really would like to be a part of one day. I wanted to discuss, considering the limits of current technology, if it would be possible to create a safe Dash Charging power bank for this device? For those who don't know how dash charging works I'll post a few links and my understanding of how it works and if I'm wrong at any point feel free to correct me.
Dash Charging - The Technology
The way dash charging works, as I understand it, is that the USB-C cable wires are made wider in diameter to accommodate a larger amount of current being passed through to the battery. The charger plugged into the wall takes on the burden of the extra voltage pushing the current through the wire and keeping it away from the phone's internal battery (which is brilliant). That means that the charger takes on the extra heat which isn't a problem because passive components are often more tolerant of heat than batteries are.
Links:
http://www.phonearena.com/news/How-it-works-Dash-Charge-fast-charging-on-the-OnePlus-3_id82646
http://www.trustedreviews.com/opinions/what-is-dash-charge-oneplus-3
The Issues
A dash power bank could be charged up exactly like the phone; with the dash charger it could fill extremely fast. However, using the battery pack to charge the phone means that the internal Li-Ion batteries of that charger will be taking on the extra heat from within the case which could:
a) shorten the power bank's life span
b) Possibly lead to unsafe power banks if it got too hot
I also see there being limitations with the power bank's ability to maintain a full speed charge similar to wall charging along with what types of batteries would be needed to provide the power output similar to the dash charger.
The Solutions
So in my limited knowledge I think that the biggest enemy here is heat generated in the power bank. I feel like the rest could be overcome with a fairly large bank of 18650 batteries. It is possible to have a passive cooling system built into the power bank for heat dissipation but that might make the battery bank difficult for users to hold on their Pokemon Go outings. Also, reducing Dash Charging specifications just a little, decreasing the speed at which it could charge the device, would alleviate some of the concern. So while you might not get 60% in 30 minutes from the wall, perhaps aiming for 45-50% charge in that amount of time would increase the power bank lifespan and total amount of charges.
What do you all think? I'll readily admit I don't understand completely how current battery bank internals work to limit over-current and over-voltage scenarios as I've never taken one apart. If anyone wants to educate me and say whether they think Dash Charging is possible I'd love to hear about it. This is the kind of stuff I imagine the OnePlus engineers are sitting around working on every week.
i think that would be too expensive to make for consumers, u figure if a dash charge block is almost $30.00 this thing would be well over $500.00 which would be too much for a regular consumer to purchase just to have a portable charger, maybe in about the 3rd or 4th generation of this technology we could see one in about 5 years, they would rather make a ton of 30.00 purchases and have you buy their charge block opposed to very little purchases of about 500.00 for power bank
It's actually already there in the market,
named "OPPO VOOC Powerbank"
attached is mine, working fine with OP3 Dash,
Price is around $45-50 - 6000mAH
Charging rate is 3,5A
and it DOES charge my device up to 60-70% in 30 Minutes
it heat up though, especially near the plug (USB C end)
this is why i use the metal based USB C adapter, so it release the heat faster

Here,
the information page from the maker itself :
http://www.oppo.com/en/accessory-vooc-power-bank
and where to get it :
https://www.amazon.co.uk/OPPO-VOOC-Flash-Charge-Power-White/dp/B00SINEEXA
I'm going to build power bank using Dash Charge car charger. The power banks higher voltage (12V if using car charger) means less current for individual cell while charging. I have bought battery holder case 10 x 1,5V for AA batteries. http://r.ebay.com/vpShFJ (I already have plenty of Eneloop AA batteries for other accessories.) Each Eneloop has at least 1,5Ah (1500mAh) capacity while retaining voltage at or over 1,2V. http://lygte-info.dk/review/batteries2012/CommonAAcomparator.php I'm going to attach 12V socket to the battery holder case so I can use my car charger both in car as well while at camping.
Battery bank consisting of 10 x AA Eneloop has a total capacity of: 12V*1,5Ah=18Wh.
Dash chargers input is rated at 12V/2.5A so each individual Eneloop would have about 250mAh discharge rate.
My old Galaxy Note 3 had 3,8V 3200mAh battery and the capasity was ~12,2Wh. I don't know the nominal voltage of OP's battery but I would estimate it's about the same as Samsung's so the capacity should be lower than in Note 3. Maybe around: 3,8V*3000mAh=11,4Wh.
10x Eneloop batteries has a capacity to give energy for charging OP3 from 0% TO 100% at least. (18Wh/11,4Wh = ~1,6)
I think in India it's not available

We're going to need a hardware XDA for people like you. I never would have thought to string together Eneloops to make an external charger since most of your power banks contain 18650 with overcharge protection and stuff built in. The wall dash charger is spec'ed to run 5V at 4A and the car charger loses half an amp to land in at 3.5A max. Car charger voltage varies between 3.4~5V from what I can tell probably based on the car's cigarette lighter specs.
What kind of case are you using with the eneloops and what are you using for overcurrent/voltage protection?

So... can you tell me if a normal VOOC charger block charge the OP3 as fast as the original dash charger in package?
I saw it is the same current rate, but the technology, is it interchangeable?
Just wait oneplus is planning to release a dash charge powerbank with 10000mAh so stay connected no need to buy oppo 6kmAh one

You are right, the car charger uses lower current and is probably a bit slower. When I receive my car charger I will do some testing and will report back.
The voltage variation is needed on all chargers. When the battery is almost full the charging voltage drops.

I have ordered a case like this: http://r.ebay.com/vpShFJ
The car charger has been designed to be used as it is. The charger itself does not require additional overcurrent protection but in case of a short circuit a 5A fuse is needed to protect the wiring and Eneloops. Overvoltage is not a problem as the maximum voltage with Eneloops is going to be under 15V.

Yes it is. I've posted it in another thread as eell. Just check through my post history.
This is pure logical, since Oneplus is just a subsidiary company of OPPO, so they surely can share few technologies between each other, and VOOC/DASH is one of it,
Just make sure your usb c adapter quality is good when you decide to use it with VOOC charger.
For review today, I have an Aukey PB-Y14 Powerbank rated at 20000 mAh. Overall I really like this Powerbank. It is very versatile in so much that it can be charged with a lightning plug, USB-C, or Micro-USB. For outputs it has 3 USB-B plugs and the lone USB-C is also an output. Charging speeds are slow being that this powerbank doesn’t support Quallcom’s QuickCharge in any way. Having said that it still does a great job. I already owned another Aukey powerbank (Model PB-T10) which does support QuickCharge 3.0 and it is very fast. Once depleted, the PB-Y14 takes quite a while to charge, but to be fair it is a pretty large battery. It has only needed to be charged once since I’ve received it, and so far it has charged my Note 9 twice and my Chromebook once, battery life as indicated by the row of LED’s on the side shows 50%, so it seems to be holding its own quite well and I like the battery display on this unit much better than that of the PB-T10 which shows you a colored led and you must remember which color coincides with what power range. In summary the PB-Y14 is a very good power bank but would not be my only choice. I like it quite a lot, but I also like my PB-T10 an equal amount. I will continue to keep the PB-T10 in my daily carry bag and perhaps keep the PB-Y14 around home for emergency power in case of outage or possibly to be a mobile power supply for a small computer such as a raspberry pi. My recommendation would be to weigh out your needs as these are both high quality and very affordable. If you must have fast charging, go for a different model such as Aukey’s PB-T10. If you have a need to charge more than 2 devices (the PB-T10 only has 2 outputs) or greater versatility for charging your powerbank (the PB-T10 only has lightning and micro-usb inputs) go for a PB-Y14.
