Hello,
I have noticed that everytime - no matter if the phone is charging when On or charging when Off - original HTC charger charging U11 with range 0% to 75-80% with 7V and 2A which gives 14W. It's not QC 3.0 but more likely QC 2.0.
Do you have the same results when charging U11?
What is interesting when I connect to original HTC charger other device which supports QC 3.0 like i.e. powerbank - then I get during charge output 12V and 1,6A which gives ~19W.
What happened with U11 that charging is much bellow results I get when charge powerbank?
I think you confused the definition of QC 3.0.
The Maxi power of both QC 2.0 & 3.0 is 18W, so you can't tell the QC version by judging the charging power.
The 3.0 version big upgrade is the dynamic charging voltage compares to only 4 modes of 2.0.
It's maybe HTC limited the maximum charging power, while your power bank does not. But they are both QC 3.0. All the difference you might get from these 2 chargers is a few minutes difference from 0% to reach 100%. To me it's not a problem at all.

According the specification out V10 supports Quick Charge 2.0.
Does this mean any charge that support Quick Charge 2.0 should work? or it more hit or miss?
I purchased this http://www.amazon.com/gp/product/B0144S0PDK
and when I connect it I don't see it indicating quick charge.
thanks
This one is tricky. Regular high-amp (2.1A) chargers don't seem to do the trick; its more about amps AND volts on this phone. The only other charger I've gotten 'fast charging' to work with is the Motorola Turbocharger I got with my Nexus 6. I suppose if you found a charger that outputs the same amperage and voltage as the LG charger it would work, in theory.
The charger that came with mine is a fast charge charger. It shows fast charge when I plug it in.
The charger that comes with does indicate quick charging when I plug it in to it.
But the car charger that I purchased that claims quick charging support does not indicate quick charging when I plug it in.
Was looking for others experience to decide if I should return and complain.
Unless the chargers say that they are Quick Charge 2.0 or 3.0 they don't quick charge our phones. AC or Cigarette lighter charger. Now, there is at least one brand of charger out there that @ 5 volts DC used to charge my Note 2 at 1800mA, but it was smart not quick.

It does..i bought a quick charger for my htc one m9 before and it shows the fast charging when i tether the v10 to it
The phone will detect if it will quick charge when connected to a QC 2.0, you don't get a QC when you plug it in instantly, it will also depend on how much power you already have in the phone.
Aukey is a authorized with QC 2.0 and is listed in Qualcomm site.
I've got the power..

What RDI said.
"Quick Charge" is not "Fast Charge" or "Adaptive Charge" - All of my 2.4amp Fast Chargers do not charge the G4 or v10 any faster than an old iphone power cube. YMMV
The V10 is Quick Charge qc (Qualcomm) 2.0.
There are already a couple of threads on the subject. here and here
@ZEROLEMON_OFFICIAL makes one of the best IMHO. Anker, Aukey/Tronsmart, and Motorola Turbo Chargers have qc 2.0 compatible ones. (always a sale on groupon or slickdeals)
Our phone, like the LG G4 switches to Quick Charge when the main screen is off. And tones it down to standard charging speed if you have the main screen on. The v10 Quick Charges at about 2850mA, slightly faster than the G4 at 2000~2200mA, but slower than the Nexus 6 at 2700~3200mA.
Attached are results by CoNsPiRiSiZe on this AT&T variant, and mine on Tmobile variant. Also included is my USB Doctor Sleeve using a Motorola Turbo Charger plugged into the v10 with screen off.
I am using the Samsung adaptive car charger while driving and it shows fast charging on the lockscreen

Turns out I had a bad aukey charger, I bought another for my wife and it works fine, show quick charge.
Returning the bad one and getting another.

I have paid version with notificaion ebabled. But you can run it, leave phone alone so it can meassure. Then turn on screen and screenshot results. It takes a few seconds before it drops or remeassures.
Do these really charge all that much faster than a 2.1a charger? Debating if it's worth it to go invest into a few of these QC chargers.
Thanks

QC 2.0 allows up to a maximum of 3A of current. Every QC 2.0 enabled device will vary slightly in how much power they can draw due to internal circuitry. The V10 charges at about 2.85A as shown by Clockcyle so yes, a QC 2.0 charger will charge faster than a standard 2.1A charger.
Excellent, thank you! Going to pick up some of them now then.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Mi A2 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
The phone ships with a quick charge 2.0 charger. The phone supports 3.0 and also 4.0 for India markets. Mine is Malaysian so it's 3.0. With stock charger it takes 1 hour 20mins + to get fully charged. Not too bad. With a QC 3.0 charger (Using my mi max 2 charger) it takes about less than an hour to get fully charged based on estimates. Charges quite quickly to 70% so stock charger is actually fine.
I think it supports USB PD as well, I used my pixel 2xl charger and it showed that the phone is charging rapidly, will do another full test and post results!

If it's the global version, it should be QC3.0 . QC4.0 is only for India if I am not wrong.

Oh that's sad. Is it worth buying a QC 4.0 charger anyway? Or is that wasted money?

I don't think QC 3.0 is that much slower compared to QC 4.0. It's not like Oppo's new charge system, now that's quick haha. QC 3.0 is fine. I am still using QC 2.0 and it's all good no issues with it.

Phone supports quick chargers from xiaomi only. I have tried 2 different qc 3.0 certified chargers and both get 1800mah to my A2. My charger from my old Mi5s plus works fine and gives 2400mah.

I got the cheapest qc 3.0 from Amazon, tycipi or something like that. According to ampere app it is providing 2400 mah, it charges the phone quickly
I got the global version, so only QC3.0.
I have an Aukey PA-T8, 8 ports 5V 2.4A, 2 QC3.0 ports.
On 2.4A port, Ampere say 1800mA.
On QC3.0 port, Ampere say 2300mA.

If you own a Global Version, your device will only support QC 3.0. Only Indian Variants support QC 4.0
My A2 unit is behaving quite strange, first let me say that Ampere is not so reliable as a USB power monitoring device, which I have (this unit gets you also the voltage which is being supplied to the phone).
MY measurements (with supplied USB-C cable) are:
- Stock charger: 1,6A voltage 5V
- QC 3.0 charger: up to 2,4A voltage 6,5V
- QC 2.0 Charger (works with Asus Zenfone 2 and Galaxy S8 on quick) - sometimes ZERO - just shuts down after a minute
Other 2A 5V chargers often not more than 0,6A (depending on cable)
So, A2 is very sensitive with cables and charging electronics and probably cannot accept 9V.
Global version.
Sometimes the phone when plugged in charger shows "Charging slowly" and sometimes "Charging Rapidly", What's up with that?

With a Power Delivery 3.0 charger and smartphone off, it can surely be charged with a voltage of about 9V.
I don't know if it's possible also in other cases.
Is the QuickCharge 4.0 a software or a hardware feature in the Indian version? Just wondering if QC 4.0 can be "unlocked" in the global version through future software tweaks?
With the stock charger , it's charged after 3 hours it's normal ?

Does Xperia X supports Quick Charge 3.0? What happens if we use 3.0 charger?
prob it will work at qc 2.0 speed
QuickCharge is backwards compatible with the previous versions. I use an Aukey PA-T9 QuickCharge 3.0 charger on my Xperia X and it charges way faster than the standard charger even through Xperia X is certified for QC 2.0 only...

The original Xperia X charger doesnt have QuickCharge 2.0 (at least mine didnt had) thats why is faster with your PA-T9 charger , i think if u take a QuickCharge 2.0 and a 3.0 and test them on Xperia X it will charge at the same speed (QC 2.0)

Xperia X shipped with a Quick Charger only in a handful of countries, I also got a standard 5V @ 1.5A charger with mine.
Also, I'm not implying that QC 3.0 is faster than QC 2.0, I'm just assuring the OP that Xperia X can get fast charged with a QC 3.0 charger even through it's certified only for QC 2.0.
I think I broke something on my end. So yesterday I charged Samsung Tab 4 with my "new" QC3 UCH12 charger from ebay( before I charged my phone and it was fast) and now my phone can't charge more than 0.7A and it says it's on 4V. But in the mean time I connect my standart UCH20 5V @ 1.5A it charges at 1.5A but sometimes it goes to 1 or 0.7A but then goes back to 1.5A. Any tips?
Also sometimes it just won't charge my phone. Like it would connect for a second and then disconnect.
I would really like to get some help

QC charges depending on how much battery u have left in your phone and some nonbrand chargers are pretty bad and they dont work as intended with some phones.
Hi i read that redmi 5 plus support qc so i had aquired samsung quick charger.When plugged phone shows quick charging but when i mesure mA while charing with qc and with normal charger there is no big difference according mesuring software.So what is real truth about qc?

Redmi 5 Plus supports QC (3.0 to be exact, as it's Snapdragon 625). Apps measuring charge rate won't show you real current, it's only approximation.
I've tested my charger, which supports QC 3.0, my 5+ uses 9Volts at almost 2Amps (when charging from 15-20%). Measuring software won't show you voltage that you are using to charge so you may not see the difference. But doing quick math - 5V*2A=10W (standard charging brick) whereas QC charger will use 9V*2A=18W. That means you are charging with 80% more power.
Keep in mind that charging with QC will get your phone a bit warmer, so phone will start to throttle the current, meaning that you won't be charging from 0% to 100% at full 18W
Yes. It charges with 9v and 1,7 amp max. (9v is static, amp is variable, that means it has only QC 2.0 mode.)
Its way faster than standart charger. I have Tronsmart QC 3.0 charger. But you can go with QC 2.0 charger.
Hi, I would like to ask about SuperDart 65W (10V, 6.5A) from Realme 7 Pro. It charges every of its two batteries at 5V and 6.5A (32.5W each) but I found information that it suppots Power Delivery and Quick Charge 18W as well. With PD and QC you can charge the battery at 9V , 12V, 15V etc. but not 10V. Does anyone know at what voltage the smartphone will be charged if you use PD or QC charger?
Is it safe to charge it with higher/less voltage? (e.g. 2x4.5V or 2x6V if 5V is needed for one battery)
And what about the standard 5V chargers and usb 3.1 (e.g laptop)? Is it possible to charge 7 Pro with it?
Generally, all fast charges will drop ther voltage when the connected phone doesn't support it.
With lower voltage you wont have any problems other than the speed of charging, which will obviously decrease
Standard 5V chargers will work just fine
Normal laptop usb will work just fine, in fact you will be lucky if the laptop supports any sort of fast charging at all
You are 100% safe to charge with pretty much any charger to my understandment
