QuickCharge 2.0 Z3 Compact - Not working

Hi,
I bought the incipio QC 2.0 car charger.
I got a Z3 Compact and I cannot seem to get the QC 2.0 working.
I charges about 1% /min which is the same speed as the EP880 charger that came with the box. Batterymonitor tells me it pulls about 1700Ma from the charger.
However, according to other threads QC 2.0 should be charging about 2% /minute up to about 70% of battery. I'm using the original cable and connect to USB port, not the magnetic port.
Is it possible to know if the phone is charging at 5v or 9v? according to QC 2.0 it should be charging at 9V. But if that was the case then I should be getting more than 1%/minute.
Has anyone verified that this works ?

I don't own a quick charger but with my charger the phone pulls 5.3v and 2100mah. I'm using a USB power monitor to get the readout. It's very fast at charging maybe these 2%/min..
Could you provide me a link to that 9v charging? Never heard about this before...

Hi,
Since I'm a new member on XDA I cannot post links.
But search for Qualcomm quick charge 2.0 and you find the qualcomm site.
Qualcomm lists the Z3 Compact as a QuickCharge 2.0 enabled device as long as you have a certified Quickcharge 2.0 charger.
I got this repsonse from Incipio support, which is the manufacturer of the charger.
"Hello
Thank you for your email. The quick charge will output 5V unless the device you are using is quick charge 2.0 compatible. If you are using a device that is quick charge 2 compatible, the charger will then output 9V. I am unaware if the Z3 compact has qucik charge capabilities, but if it does, there is no special cable required. I hope this helps! If you have additional questions, please let us know.
Kind Regards, "

Try charging the phone when the battery is below 10%. The quick charge will not work once the battery reaches a certain level. I think once the battery reaches 30-40%, quick charging stops and regular charging begins. It could be different for different phones and I am just making an estimate here.
I don't see why you bought a third party one when the EP880 is a quick charger. Did you face any issues with the EP880?

The EP880 is indeed a quickcharger (QuickCharge 1.0 spec, 5v, 1.5A), but not a QuickCharge 2.0 charger.
De big difference is that a QuickCharge 2.0 charger will charge the phone twice as fast as the EP880(QC 1.0). The other difference is that a quickcharge 2.0 charger will output 5v, 9v or 12v depending on what device is connected.
The Z3 Compact is compatible with QuickCharge 2.0 according to Qualcomm and should charge at 9v if connected to a certified QC 2.0 charger.
Hope that explains why I bought a third party charger.

i recently bought the tenergy quick charge 2.0 charger.. here's the link http://www.ebay.com/itm/390960208671?_trksid=p2059210.m2749.l2649&ssPageName=STRK:MEBIDX:IT i got it for 20 uss.. now is 60 uss btw its a certified quick charge 2.0
some test i did with the usb cable... first when i plugged in the charge is really fast!.. later in 60 or 70% the charge reduced a lot.. in 1 hour charged from 5% to 70%

this is the voltage specification of the charger... 5v 2A normal charge (blue led indicator) 9v2A is quick charge 1.0 (blue led indicator) and when you connect a compatible device is a green led indicator 12v 1.5 is quick charge 2.0..
Pros: - Fast charge 0 - 70 % in a 1h10min
cons: - doesn't recognize the cellphone with the magnetic charging cable as a quick charge 2.0 (only indicates with the blue led indicator as a normal device :crying: )

Yea I wished quick charging worked with the magnetic adapter but I only charge at night anyways. Though when I do need a boost fast I will use USB. I got my tenergy for $20 on amazon.

you can use this charger... but its not a quick charge.. because quick charge 2.0 use a different voltage output.. 12V 1.5A

0 - 70% in 1h10min is what I get with the EP880 charger. If the charger is truly using QuickCharge 2.0 you should go from 0-60% in 30mins.

i think 0-60% is with the phone off... ill try it.

Just got my own quickcharger 2.0 and I can confirm it doesn't work on the magnetic port. This is no surprise, as QC 2.0 needs the data ports of the USB port that the magnetic port doesn't have.
I'll play with it a little bit more later but with the actual USB cable plugged in to the mini-usb connector I saw 7.5V and 0.7Amps being pulled in, so that's definitely Quickcharge 2.0. although it was only about 5W going in. Charge was around 80% so that must be why it was not pulling in more juice at the end of charge.
I'm on the USA stock firmware, latest version.

Hi,
Im located in Sweden with firmware 23.0.1.A.5.77
The thing is that the phone pulls about 1800mA from the QC 2.0 charger (according to battery monitor).
Even with this new firmware it charges about 1%/minute. (0-60% in ~55minutes).
This is not the "QC 2.0" speed. Sony doesn't seem to have any official information about it.

today i tested charging from 0% with the phone off.. 0-30 min only 37%... next i turned on the phone and charge 30-60 min to 65%, 60-90min 90% and 90-120min 98% pretty dissapointed about the quick charge 2.0 ;(

My thoughts is that.
1. QC 2.0 is not fully supported by Z3 compact, or at least by the latest generic firmware
2. Maybe it will come a future FW update that will support this
3. It could be that the hardware (battery?) does not support QC 2.0 and therefore Sony didn't implement it.
4. It could be that other revisions of Z3 has slightly different hardware and some has QC 2.0 capability and others do not.
so many questions, so few answers

I don't have hard data, but I recent bought (and have since returned!) a Power Partners PEAW30-12-USB QC 2.0 charger and saw NO decrease in charge time compared to the stock Sony charger. Very disappointing. No potential of QC 2.0 functionality thru the magnetic charger sucks anyway.

I got myself a QC 2.0 from amazo (Aukey) which is Qualcom certified.
charging mij Z3Cwith the QC2 goes just as fast as my 5port 40W charge station (2A / port) @ 1355mA
when plugged my z3 Tablet Compact into the QC2 charger it charges upto 2677mA !
so short to say, Z3 compact is not QC2 ready
Z3 Tablet compact is
hopefully they enable this with some FW upgrade

For your information EP881 is not a QC 2.0 charger.
Done some testing and the Z3 Compact pulls 9v , 1A from the QC 2.0 charger. According to voltage the handshake between the QC 2.0 charger and the Z3 Compact seems to be working as the phone pulls 9v and not 5v from the QC 2.0 charger.
I would love to see it charge at 9v, 2A which is the true QC 2.0 speed.
Sony can't explain why it's only pulling 9v, 1A. Hopefully we will get an answer within the next months or so

Review of Aukey Quick Charge 2.0 wall charger (adaptive fast charging) w/pics!!!

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.

OnePlus Two Charging Analysis

Hi Guys
Today we will show you the charging analysis for the popular OnePlus Two smartphone.

You should read a lot of OPT reviews from different site, but as a brand which offer chargers, we will only focus on the charging analysis for OPT2. We will test the original power adapter, suggest for how to quick charge your device, and help to pick up the correct alternative chargers. Here we go:
First, Let’s check the original power adapter and Usb to Type c cable:
The charger is regular 5V/2A power adapter, the specification on the charger is:
Model: AY0520
Input: 100-240V 50-60HZ 0.3A
Output: 5V/ 2A
The cable is interesting, Oneplus redesigned the usb port again,which make you never worry which side to insert, and the other port is USB type C, this cable can be used for charging and data transfer. The total length is about 3.5ft.
So this charger don’t support higher volt,(9V or 12V) and We can confirm that, even the OPT2 use the Qualcomm Snapdragon 810 processor, however, the OnePlus Two don’t support Quick Charge 2.0 Technology, We test with our chargers which support QC2.0, It just can get 5V volt, never get higher at 9V. You should read this news from different source, It’s a pity that they drop this amazing features, but We still want to give it a test for how the charging performance.
First we test the no-load voltage of their original power adapter:
I don’t connect any device to the charger, just use the ammeter to test the volt is 5.13V. It’s in the normal range ( the normal range for the charger should be 4.75V-5.25V, any chargers’ no-load voltage exceed this range will have problems), and then we make the oneplus two battery to 0% and begin our test: Here is our test result with original oneplus two 5v/2a power adapter, and usb type c cable:
Time Baterry Current
4:40pm-4:50pm 0％-17% From 1.89A to 1.85A
4:50pm-5:10pm 17%-33% Keep at 1.85A
5:10pm-5:40pm 33%-60% Still at 1.85A
5:40pm-6:40pm 60%-98%
6:40pm-6:50pm 98%-100%
From the above tablet, we can see, in the first 10 mins, the oneplus two get very fast charging, battery charged from 0%-17% in the first 10 mins, and we check the charging current, it is from 1.89A at first, then become smaller till to 1.85A. And then in the first 30 mins, it get about 33% battery. ( compare with the quick charge technology, about 60% battery in 30 mins, the oneplus two charging is slow). But the total charging performance is not that BAD, It take about 2 hours 10 mins to get the full charge (from 0%-100%). check the current tablet, before 60% battery, it get charged always @1.85A high current, and after 60%, the current will change smaller, from 1.85A to 1.83a and 1.79a, and smaller, because that change is fast, we don’t record every current.
Now we begin to test the charging performance with our chargers:
no-load voltage for tronsmart wall charger and car charger ( all of our tronsmart chargers are conform with the international standard)
Use the Tronsmart Wall charger and Tronsmart USB Type C cable to charge the Oneplus Two:
The charging current is the same as the original power adapter. The oneplus two don’t support QC2.0, so our chargers can’t give it faster charging speed, but at least,we offer the same good quality as the original power adapter.
In our testings, we found some interesting things:
1 If you make the screen on, the charging current will directly reduce to under 1amp, and with screen off, the charging current can reach 1.9a.
With screen off:
With Screen On:
2 If you use a low quality charger which can ‘t offer enough 5V volt, the OnePlus Two charging current won’t higher than 1amp, the charging speed will be super slow.
So how to make the charging speed faster on OnePlus Two, here are our suggestions:
1 Use the original or high quality power adapter and high quality USB type c cable;
2 Don’t use your phone all the time when you charge it, with screen on, we can see the charging current is really small.
Why Choose Tronsmart chargers:
All of Tronsmart Chargers are get certified by CE, ROHS, FCC and other certifications, all of our quick charges are certified by Qualcomm(you can find our name in the Qualcomm quick charge list), and we are also proud to be the featured quick charge brand in Qualcomm Official site. So You don’t need to worry the quality of Tronsmart chargers.
More and more flagship smartphone will support quick charge 2.0 technology, Samsung, Sony ,LG, Moto, all of these brand flag ship support quick charge, Tronsmart offer the world’s most abundant quick chargers. From 1 port usb wall charger to 5 port and from 1 port usb car charger to 4 port.
All of your families can get the fastest charging speed no matter what device they are using!
And more Tronsmart design a unique USB Typc C car charger for Oneplus two users, check it here:
Traditional, You need to prepare a high quality car charger, and high quality USB type C cable to charge your Oneplus Two in your car, but with Tronsmart USB Type C car charger, Never bother of this, plug our car charger , and charge your Oneplus anytime. also we offer another port which support quick charge 2.0 for your family’s Samsung, Sony, LG, Moto etc.
So above is our charging analysis for OnePlus Two, if you have any questions, feel free to leave comment below.

Good Job! Very professional! Look forward to more analysis such like this post.:good::good::good::good:

@GeekEric
What do you think of the below combination of components, will it achieve faster charging times for our oneplus 2 ?????
1.BlueRigger Rapid Charge Micro USB Cable - 6 Feet (does not support data transfer)
2.ImagineDesign USB Type-C Adapter : USB Type C To Micro USB
3.Amkette USB Wall Charger Duo for Mobiles & Tablets
I do not need your confirmation about any test results.
In theory, should the combination achieve faster charge times or not ??????

It charges from empty to full in 2 hours! why would anyone want faster than that? There's very little chance that a battery will be zeroed in normal use so charging times will be less anyway. Don't waste time and money trying to get a few seconds faster, just charge the thing overnight. Carry a power pack if you really need more than the battery can provide in a day.

Are you using the original cable and powerbrick? Some third party cables don't support higher currents, which slows down the charging.

4:50pm-5:10pm17%-33%Keep at 1.85A
5:10pm-5:40pm33%-60%Still at 1.85A
5:40pm-6:40pm60%-98%
6:40pm-6:50pm98%-100%
From the above tablet, we can see, in the first 10 mins, the oneplus two get very fast charging, battery charged from 0%-17% in the first 10 mins, and we check the charging current, it is from 1.89A at first, then become smaller till to 1.85A. And then in the first 30 mins, it get about 33% battery. ( compare with the quick charge technology, about 60% battery in 30 mins, the oneplus two charging is slow). But the total charging performance is not that BAD, It take about 2 hours 10 mins to get the full charge (from 0%-100%). check the current tablet, before 60% battery, it get charged always @1.85A high current, and after 60%, the current will change smaller, from 1.85A to 1.83a and 1.79a, and smaller, because that change is fast, we don’t record every current.
Now we begin to test the charging performance with our chargers:
no-load voltage for tronsmart wall charger and car charger ( all of our tronsmart chargers are conform with the international standard)
Use the Tronsmart Wall charger and Tronsmart USB Type C cable to charge the Oneplus Two:
The charging current is the same as the original power adapter. The oneplus two don’t support QC2.0, so our chargers can’t give it faster charging speed, but at least,we offer the same good quality as the original power adapter.
In our testings, we found some interesting things:
1 If you make the screen on, the charging current will directly reduce to under 1amp, and with screen off, the charging current can reach 1.9a.
With screen off:
With Screen On:
2 If you use a low quality charger which can ‘t offer enough 5V volt, the OnePlus Two charging current won’t higher than 1amp, the charging speed will be super slow.
So how to make the charging speed faster on OnePlus Two, here are our suggestions:
1 Use the original or high quality power adapter and high quality USB type c cable;
2 Don’t use your phone all the time when you charge it, with screen on, we can see the charging current is really small.
Why Choose Tronsmart chargers:
All of Tronsmart Chargers are get certified by CE, ROHS, FCC and other certifications, all of our quick charges are certified by Qualcomm(you can find our name in the Qualcomm quick charge list), and we are also proud to be the featured quick charge brand in Qualcomm Official site. So You don’t need to worry the quality of Tronsmart chargers.
More and more flagship smartphone will support quick charge 2.0 technology, Samsung, Sony ,LG, Moto, all of these brand flag ship support quick charge, Tronsmart offer the world’s most abundant quick chargers. From 1 port usb wall charger to 5 port and from 1 port usb car charger to 4 port.
All of your families can get the fastest charging speed no matter what device they are using!
And more Tronsmart design a unique USB Typc C car charger for Oneplus two users, check it here:
Traditional, You need to prepare a high quality car charger, and high quality USB type C cable to charge your Oneplus Two in your car, but with Tronsmart USB Type C car charger, Never bother of this, plug our car charger , and charge your Oneplus anytime. also we offer another port which support quick charge 2.0 for your family’s Samsung, Sony, LG, Moto etc.

What do you think of the below combination of components, will it achieve faster charging times for our oneplus 2 ?????
1.BlueRigger Rapid Charge Micro USB Cable - 6 Feet (does not support data transfer)
2.ImagineDesign USB Type-C Adapter : USB Type C To Micro USB
3.Amkette USB Wall Charger Duo for Mobiles & Tablets
I do not need your confirmation about any test results.
In theory, should the combination achieve faster charge times or not ??????

I have bought 2 of the cables. They are very nice. Until they break. Which usually happens within 6-8 weeks.
I usually stick to Anker or Kopi (Kopi is getting hard to find).

Yup. Everything original OnePlus.

[Official] ✘ This is how we ROCK ✘ ~ OnePlus Homescreen set-up's!!
Wow what a pro writeup... Thanks for going in-depth!

So this points out a major issue: it takes 4 times as long to charge if screen is on. That means +8 hours until full! What the ****, oneplus... Hopefully this is something we can fix with a custom kernel.

Nice and in details.. thanks

Amazingly detailed OP well done.
I have noticed that the Nexus 6p and Nexus 5x also have the same USB-C v2.0 so my question is, why do the Nexus phones charge faster? I believe the Nexus 6p used a 5v/3A charger versus the 5v/2A OnePlus2 charger.
With this in mind, would the OnePlus2 charge faster if we were to use a 5v/3A charger? Since it's using the same USB-C v2.0 standard?
Thanks

RAVPower 20100mAh Quick Charge 3.0 Power Bank – Unboxing & Review

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?

What power bank are you using for fast charging on your Tab S4? QC 2.0 not working

I have two fast charge power banks, one Anker PowerCore+ QC 2.0 and an iWalk Secretary. Neither will fast charge the Tab S4. Nor will plugging in the Tab S4 into the 3.0 and 2.0 quick charge ports on my Anker and Aukey multi port charging stations. The maximum charge (using AccuBattery app) I'm getting on these fast chargers is 500 ma and pretty up and down not really consistent. When I connect to a standard port it goes up to 900 ma without any dips. When I connect my Note 9 to the same fast chargers I'm getting 1300 ma.
Is this a Snapdragon issue?
Are you getting 800+ ma charging consistently with your power bank? If so which one are you using?

i never ever charge via fast charge as it destroy the battery in the long run, but i own an Belkin 15000 milliamp power bank.. i have just switched on fast charge for you I’m getting 1375ma charge that’s what AccuBattery is saying I’m averaging that of my power bank..
I hope that answers your question? pp.’s never i have heard of iwalk bit of advice avoid unknown brands! Anker is good but I don’t know about iwalk, get the Belkin one that I own.. I have charged my Note 9 twice in the last few weeks once full and once around 70% and I have charged my Tab S 8.4 LTE fully once and I still got 3 led lights left on the Belkin power bank..
Mate this Belkin power bank is a beast!

I will have to install accubattery but I have a Anker PowerCore 20000 with Qualcomm Quick Charge 3.0 and it works pretty well for what I need. but looking to upgrade to more power but smaller in size.
https://www.amazon.com/Anker-PowerC...re+20000+3.0&qid=1550676139&s=gateway&sr=8-13

These tabs support QC2.0 which allows for a theoretical 5V/2A or 9V/2A. In practice I've never seen it above 9v/1.7A. Does your accubattery app actually indicate the negotiated voltage? Or just the amperage?
The only way I've found to reliably check chargers, cables or devices is with a hardware ammeter like this:
Mini USB Tester DC Digital Voltmeter Ammeter LCD Display Current Voltage Meter Detector Power Bank Charger indicator Amperimetro
https://s.click.aliexpress.com/e/3rPyJb6
I've got one like this (reads 9volts despite the spec sheet stating otherwise):
| LCD USB Detector Voltmeter Ammeter Mobile Power Charger Capacity Tester Meter Voltage Current Charging Monitor 3V-7V DC 3-7V
