Based on the specifications off the Chinese website, supports only 5v/2a. Not sure hardware, software or licensing limitation.

I have bought a MiPad 4 (3+32).
If the QC3.0 charger is used, it will only up to about 12W. It still needs 2.5 hours.

The tablet does support QC 3.0 but the included brick does not.

Do you have any device that would measure the voltage and amperage??
It would be great to get the actual reading...

I have one Mi Pad 4 (3Gb/32Gb Wi-Fi) and with the battery at 20%, charging in a QC3.0 port, with the screen off it went to 1.85Ah at 5.05V. It was around 9Wh. So i can tell that it probably will go to 10Wh maximum and so it has probably only support for QC2.0.

I used a UGreen wall dual charger (one port QC3.0, the other is 2.4Ah) and the cable also a UGreen nylon that supports fast charge. They are found very easily in ebay and I strongly recommend this brand for charging (value/quality). For measuring I also used a very common usb tester that goes up to 5.1Ah/30V found also in ebay.

I can tell that with that same charger and cable, my Le Max 2 goes to a maximum of 24Wh(!) (around 8V/3Ah) when it was around 10-20% battery. So I can tell that the charger is at least outputing that power.

I confirm that no matter if used original charger or QC3 from Mi6 it can't charge 2-100% faster than 3 hours (usually 3h20m). Besides it doesn't show any notification about fast charging so this function must be locked.

IMO this is the biggest flaw in this tablet and I hope Xiaomi will do the same like with its Mi A1. The phone was released without the QC support, but it got unlocked with the Oreo update.

using various chargers and cables, both with miui 9 and 10.
I can say that MI PAD4 - DOES NOT have QC. it uses regular 5V/2A.

on xiaomi mi6, which clearly stated to suppoer QC, you have a sign of 'lightning bolt' on the top, as well as on the lock screen.

Mi-Pad DOES NOT.

I have an own QC adapter (not from Xiaomi). When I plug in my Mi6 it shows "fast charging". But on my MiPad4 LTE it doesnt say anything about that... So I also would say, that the normal MiPad4 has no QC support.. Maybe the PLUS has it..
