Does Xiaomi Redmi 4 Prime/Pro support Qualcomm fast charging 3.0?

If yes, Then let me know which brand of charger should i buy!

No.

I think it only supports QC 2.0, though the QC 2.0 charger does not come out of the box. But imo, who needs fast charging when the battery life can last up to 2-3 days with this phone.

in it's specs sheet in gsmarena quick charge 3.0 is listed. That's why i asked.
anyway, what's the best quick charge 2.0 charger out there? and will that charge the device faster than the original charger?

The 625 snapdragon processor does support Quick Charge 3.0, but Xiaomi prohibits using it i guess to cut cost, i know some user who try to use QC 3.0 on this phone but it doesn't work, to be honest i'm also not sure about QC 2.0, my advice is you should try testing it first by borrowing QC 2.0 charger with some of your friends/relatives that has QC 2.0 charger before attempting to buy one.

No QC 2.0 support for me, tested with new xiaomi powerbank 10000mAh, ampere show max usb current 500 mAh instead of 2000 mAh. However from measurement I can get 1700-2000mAh so still charging fast enough.

Redmi 4 supports Fast Charging (i.e. about 2A), not any form of Quick Charge. The chipset supports it, but as Xiaomi have decided not to pay Qualcomm the royalties they charge for QC, it's disabled at a low level in the phone. It might be possible to enable it via custom kernel, but I don't think it's been done yet if so.

you mean that from the measurement you're getting a CURRENT reading of 1.700 to 2.000 Amps, right? Because mAh is the capacity measurement while A or mA is the current measurement?
To be on topic, the hardware inside (global version - snapdragon) and the battery support QC v1-3 specs but quickcharge is disabled.
The phone will charge at 1.8A or 1800 mA for about 10 minutes between 20% and 55%. battery capacity.

the current raise up while you changed to a qc 3.0 adapter.

CURRENT WILL NOT RAISE ABOVE 2A by now. ONLY VOLTAGE WILL BE INCREASE, but with decreasing current.

I tested a bit :
with QC 3 compactible Aukey PA-T16 charger, Ampere shows 2030mA
with Anker 40W 5 port charger Ampere shows 1830mA.

I have a Redmi 4 (standard edition) and I also have a USB Ammeter/Voltmeter which I can use to measure actual voltage and current flow into the device.
Using a standard 2A charger, the device accepts 4.9-5.1v (average 5.0v) at 1.5A (1500ma), and rarely exceeds this due to the voltage drop of the charger circuit /transformer in the wall plug.
Using a Quick Charge 3.0 charger (Capable of 5v, 9v, 12v and dynamically 5v-12v for QC3.0), I was able to charge the Redmi 4 at 6.2v/2.1A. The peak voltage was 6.24V and peak current 2.4A (momentary).
The Redmi 4 will charge at 6.2v and 2.1A with a Quick Charge 3.0 compatible charger when the battery is totally flat. As with all batteries the current slowly decreases as the internal resistance of the battery increases as it charges.
This is 13 Watts of power, 1.7 times higher than the 7.5 watts provided by the included '2A' charger. Thus, while it does not officially have QC3.0 capability, the device is still able to utilise a slight boost from the chipset's compatibility with higher voltages. Realistically, this means you could cut down on the charge time by around 1/3, and even moreso when charging from, for example, 0%-30%.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Huawei MediaPad M5 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Hi
Last week i bought an huawei M5 wifi only Version here in Germany from amazon. Its 32GB 4gb ram wifi only Version (non pro).
I noticed very slow charging speed with the provided quick charge power supply (huawai HW - 059200EHQ). From 10% batttery he tells me 4:29 minutes and with other chargers both quick charge ajd normal non huawai it shows 5:29 hours so 1 hour more.
Can anyone confirm the charging time because the m5 pro charges this in 2:10 minutes.

Disappointed that it does not have Qualcomm QC standard but Huawei's own FCP standard.

I have non pro 10.8" 64GB M5, when I'm connecting to charger, it says 4 or 5 hours, but 10-15 minutes later it says 2:15-2:30 hours... and usually it will be 100% within 150 minutes. So its charging is really fast - actually I can't see faster yet...

I don't know of estimated charging times but charging itself with the oficial power supply is really fast.

Update for anyone interested: Tronsmart chargers with VoltIQ and QC3 can charge the M5 on fast charge.

My M5 10 Pro will arrive soon, thanks for the info.
Might get the charger as the device doesn't support QC3...

An observation.
While using and charging my 8.4 M5 from a powerbank with type c port, and type c to type c cable I notice that the powerbank only maintains the charge.
This being 5v 3 amp so 15 watts.
The same powerbank has QC3 usb ports and when I use a USB to type c cable, the powerbank on the lcd display indicates 9v 2 amp, so 18 Watts, so actually charges the M5 slowly when also being used, which I have observed.
It therefore supports QC2, being 9v 2 amp, which to be fair, Huawei says it supports 9v 2 amp, even though they don't mention QC2.

I tried a couple of stock qc2 charger like Samsung and etc with didnt work.
Tried my Aukey QC3 charger too and same no fast charging.
All are measure by electrical measurement device.

Huawei makes its own SuperCharge capable powerbank, and it doesn't break the bank.
https://www.tvc-mall.com/details/hu...or-huawei-p10-mate-9-black-sku101705094a.html
^ I ordered from that site, and received it.

As my M5 came from Amazon Germany and I'm in the UK, I haven't had the opportunity to try the standard charger that came with it having the euro pins. Seeing as I'm currently on holiday in Greece, I bought my euro charger so will try it charging my powerbank. The powerbank will report the input voltage and current from the charger...
Edit: The supplied Huawei charger says quick charger on the side, and also lists 9v 2a output. Using it to charge my powerbank, it indicates a 9v 2a input.
So in my case all my QC2, and the included charger, all output 9v 2a correctly.

I too can confirm Aukey QC3 will not fast charge the M5. Nor will a 5V3A USB C to C method mentioned by stag74. HOWEVER it does work with an unbranded QC3 charger from Gearbest, so go figure.
It appears that what will or will not work with Huawei FCP is kind of a gamble except with their own or clearly marked FCP chargers.

The supplied charger can charge items that are QC2/3 at fast speed. However the reverse cannot be said for the M5. So instead of just bringing a dual port QC charger on holiday, we will need to bring the Huawei charger as well to quickly charge everything.

My wattage gauge broke
I ordered one and will receive it in a few days and will compare

It's fast. 20% to 70% in one hour.
20% to 93% in 1 and a half hour.
Great charging speed for a tablet.
10.8 wifi variant.

With the in box charger it charges the M5 64gb 10.8 100% in around 1½ hour, thats really good for a tablet in my opinion.
I tried my Mate 20X super charger, but it only charge it the normal slow speed, i was hoping for fast charge, but no

Has anyone found a cheap charger that will do both FCP for my M5 and also QC 2 or 3 for my LG V35? What about all the various smart voltage chargers like Ankers power port, etc? Shouldn't they detect the subtle difference bt FCP and QC and supply what the device wants to fast charge?
If I recall correctly, looking and specs on the individual chargers was something like 9v/2a for FCP Huawei charger and 9v/1.8a for the QC charger for my LG V35, which my M5 won't accept for fast charging.

I use this charger, does M5 Fast Charge just fine while being a QC3 charger, so should do both. https://www.amazon.ca/gp/product/B01GFDSO1M

Car dual quick charger
I have been using this Aukey dual port QC 3.0 charger and can verify that it fast charges both the M5 8.4 tablet and my Samsung Note 8 simultaneously. I drive a truck and use the M5 tablet as a GPS unit with SmartTruckRoute. The screen is on medium brightness for 10 to 14 hours a day and never falls below 100% while plugged in. I take it off of the charger to watch Netflix and YouTube videos while eating or while in the sleeper and it shows fast charging when I plug it back in.

Fast charging power banks?

Hey there, i'm, trying to find any power banks compatible with samsung's adaptive fast charging to use with my S9+. Are there any available? If so, are they worth it?
Thanks

I bought this directly from Samsung for $16 and it does fast charge on my S9+ but it is now out of stock: https://www.samsung.com/us/mobile/m...-10ah-with-usb-c-cable-silver-eb-p1100csegus/

Shame, that's exactly what I needed. Can't find it anywhere sadly.

Any power bank that offer either Quick Charge 2.0/3.0 or USB Power Delivery through USB Type C should work. The S9/S9+ will draw 1.67A @ 9V over QC and 3A @ 5V over USB-PD via Type C and therefore fast charge at 15W (which is its limit).
These should work, though I've not tried these myself.
Anker PowerCore Speed 20000mAh offers USB-PD but not QC, though the standard USB port offers 2A @ 5V, so while not fast charging it charges at 10W from the standard port (15W from the USB-PD port for the S9+).
Charmast 10400mAh Powr Bank offers both QC3 and USB-PD.
I have an Anker power bank (non-PD), and an Aukey wall charger so can recommend those brands in general terms from my personal experience.

Xiaomi 20,000 power bank supports fast charging as well on S9 plus.

This is available now: https://www.samsung.com/us/mobile/m...-10ah-with-usb-c-cable-silver-eb-p1100csegus/

I've bought 2 different QC power banks:
AIDEAZ Power Bank 20000mAh Portable Charger
https://www.amazon.ca/dp/B07GJHNRK9/ref=cm_sw_em_r_mt_dp_U_8697Cb90CYK1E

https://www.amazon.ca/dp/B01JIYWUBA/ref=cm_sw_em_r_mt_dp_U_Q997Cb1HQ367J
NONE of them fast charge my S9+ even though when I use the wall charger it fast charges. I even have a USB power meter to confirm that these power banks are only inputting 5V 1A.
SO FRUSTRATING!

Hey that is very weird especially since you say that your dev iui ce fast charges when it is plugged into a wall adapter. I have 2 powerbanks, one Mi Powerbank 2i 10000 mAh and the other is a Samsung Fast Wireless Charger 10000 mAh and both are capable of charging my S9+ at 15W

Third Party Fast Chargers for S10+

You can use it but must be same voltage and ampers its recommended. If you example use charger with higher voltage phone can't charge with that voltage and will be charged it with default voltage and ampers i personally use qc 3.0 charger with output 5A or 9A and with one usb port which have output 3.4A and i use usb TypeC cable wich have possibility share power with 3.4A

does 25w charger shows super fast charging on phone

hello, I bought s10 plus from a friend and didnt get the original charger with it
now I was planning to buy a separate 25 watt charger for my phone
how can I check if the charger is real 25 watt ?
like normal fast charger shows fast charging on screen but does the 25 watt charger show super fast charging ?
yes or no or any other way to check ??
please help

no ... it will not show super fast charging the internal h/w of the S10+ was not designed for 25W ONLY the S10 5G model supports it and if you do plug it in, it will show you normal charging

oh ok, so the normal s10 plus just charge upto 18 watts then ??
