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.

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.
I have htc 10 charger s8 charger and transmort QC3.0. When i charge my phone with those i only get normal charging. Whick charger should i get to fast charge it.

Use fast charger provided by Huawei. its kirin chipset, so QC will not work.
Aren't all chargers that are 2 amps "fast chargers"?
The 1 amp chargers are the slow ones.
Or is there more to it?
I tried charging with an original Huawei charger. It charges MUCH quicker, compared to a 2 amp apple charger.
Strange.. I guess they have some sort of chip inside that tells the phone it is original?
There are different types of fast charging. Qualcomm Quick Chargers won't work properly in our devices, since the chip is Kirin (and not e.g. Snapdragon).
There are restrictions in each chipset that tell how much "juice" they can take and how "fast" they can handle it.
It's best to always use the charger provided by Huawei.
Charging and chargers is not as simple as "the more it gives the faster my phone will charge"
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 ?

Absolutely no
does anyone tried to charge Mi 9 with this Baseus charger?
https://www.aliexpress.com/item/32988045731.html?spm=a2g0o.cart.0.0.71f43c00TyHdOp
is this charger compatible with 27W xiaomi charging?
I think it's just Quick Charge 3.0. You should buy the 27W charger imo. But i could be wrong
I have it, it does quick charge but not charge turbo
Good I stopped by XDA before purchasing it.
It does say if you scroll down on its specs it's a QC4 charger, but I assumed the described output would be a sum of both USB ports working simultaneously.
Already posted about it some weeks ago.
https://forum.xda-developers.com/showpost.php?p=79530777&postcount=73
It's indeed just a QC 4.0 charger. Will only do 18W.
Hi, I have one. For it to work properly you have to have the cable of more than 30w.
Load much faster than the original that comes in the box. I did a quick test from 75% to 100% with the phone turned off and charged in 25min; so you can assume if it's fast or not.
WTF ; does this phone even do QC4 ... the Xiaomi offical charger is 3.0 and I bought a $68 dollars Belkin QC : 4.0+ offical as per reviews and it caps out at. 3470 : it NEVER has said fast or TURBO and it ofen Ampere reports 1800 mah ? Can anyone explain this in any way
Do you really have to post the same thing in every single charger related topic ?

Thanks for info dude
I suspect that Turbo Charge only happens with the 27W factory charger.
Because my Hama QC4+ charger, certified by Qualcomm, charges definitely faster than the 18W charger found in the package, but does not say Charge Fast or even Charge Turbo.

Call me crazy but I think it will charge the device at 27W speed.
A lot of people don't seem to realize but the "Xiaomi Turbo Charger 27W" is actually QC3, not QC4+, and it does charge the device at 27W. If you find a QC4+ charger that supports 27W and up, you will still get 27W charging but you won't see "Charge Turbo" because it will use the better, newer charging standard.
This can make charge turbo QC 3.0 and it's cheaper and with more ports:

Yeah but it can only charge at standard QC3 speeds, aka 18W at max. 9V/2A like the original one does. But the original one can also do 12V/1.5A. So it does not "Turbo Charge".
Careful many poster here are confused. My BELKIN true QC4.0+ never ever charged over 3200mA and averaged out at under 2200mA. Posters who speak about things without testing their theories are really frustrating. Do yourself a favor don't believe this phone accepts QC4 or QC 4.0+ (at least not @July 2019) only QC 3.0 NON FAKE xiaomi 27w can do the 4600mA + it would seem. Turbo charging is required for extremely rapid charge times. Make sure you get OFFICIAL 20V 1.35A from Xiaomi for Turbo Charge sustained charge and under one hour 0--100%
I also purchased a QC 4.0+ Hama DC charger cause Xiaomi doesn't make a DC charger to my knowledge. Guess what ; 18w ish charging speeds .. no Fast or Turbo classification ...
XIAOMI Hoe do you call this phone a QC 4.0/4.0+ unit !!! Cause look close at the charger Turbo pictures they are all using the "Original QC 3.0 Xiaomi charger that we ALL should have got in the box. Instead many of us have wasted tonnes of money and time buying useless to us QC 4.0+ tech that doesn't work or WORSE fake chargers that don't do more than 18w !! By the time we we have ordered 3-4 different chargers trying to get it to work we have to order it on Ali or gearbest or Gearvita. Cause the company does make them after all!! Enjoy the brutal shipping fees and heavy wait times. Well we order this and that trying to get the darn thing to work. So annoyed right now
Hi, I got the original charger and this if it gives the turbocharged 27w charge, however the baseus charger charges the same as the one that comes in the box or with the wireless charge.
I made this short video: https://youtu.be/nFBoPxORzEg
https://forum.xda-developers.com/k20-pro/how-to/mi-9t-pro-30w-charger-experiment-t4003595
read this. Also tested with a mi9 that my fried had. same result.( Turbo charging up to 30W using the baseus charger)
Posted for those who end up here like me and read mixed info
I also have the Baseus charger mentioned above (BS-EU906), the variant with 2 usb A ports.
When I charge with the cable from my samsung galaxy tab S5e it charges with a bit over 4200mA 20w-21w.
But when I charge with my Baseus 2m 5a capable cable (CATSS-B0G), it never goes above 3400mA ~14w.
It still chargers fast, but it is not what was advertised. Both the cable and charger are rated for QC3.
Baseus GaN charger 65W + Baseus 5A cable reaches 5000mA in Ampere, which is assuming 5V (that's what Ampere is assuming), equals to 25W. The fact is voltage in QC is never stable, it's the factor that allows it to dynamically supply power based on various parameters: battery temp, device temp, battery capacity and so on. If you have a USB-C USB doctor (and it should be more accurate than any software based monitoring) you can watch yourself that both the voltage and current are alternating constantly.
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
