Wireless charger not fast charging Xiaomi Mi 9? - Xiaomi Mi 9 Questions & Answers

I purchased this fast wireless charger https://www.amazon.com/gp/product/B079KZ49PJ/ref=ask_ql_qh_dp_hza but it only charges at 330 mA max. Is this a problem with the settings in the phone?

Quick Charger

Do I have to buy the Mi India Standard Charger to get faster charging speed ?
Also why is it that Mi A2 supports quick charge 4.0 in India only but I cant seem to find a qc 4.0 compatible charger ?
You can buy any QC 3.0 charger, it will work perfectly.
IS the charger that comes in the box NOT a quick charger?
Will I have to buy one?

The charger that comes out of the box is not a quick charger. You have to buy it seperately. That's one of the ways xiaomi cut corners on this phone to make it as affordable as it is.
It does, however, charge pretty quickly so maybe just give it a go and see if you need the quick charger at all.
I have a qc3.0 and the difference in charging speed compared to the original charger feels barely noticeable. I don't think I've seen ampere go over 2A with the quick charger and I've tried different cables, currently using a 3 feet, 27awg USB 3.0 one. Both the cable and charger are from Monoprice which has some pretty quality electronics so I don't think it's that. Who knows.
I also feel almost no difference on charging speed of QC3.0 vs original charger
I changed it anyways because original EU charger + low quality US adapter sent by seller is a lot bulkier than the QC3.0 that I got from Amazon
Measured with Ampere, it increases from 1700 ma with default charger to 2300 ma with a QC3.0 one

Fast charging

Is there any way we can increase the charging speed of exynos variant note 9? Coming from oneplus phone so it's really frustrating to see the charging time :laugh:
Note 9 doesn't even fast charge with oneplus's charger.
Any other charger we can use to increase the charging speed? Like Super Vooc, QC 3-4, Mate 20 pro's charger?
And what about Samsung's duo wireless charger? Does it charge phone faster than supplied wired one or the same?coz it has more Watt than adaptive fast charger..
One word: No.
Because Samsung has limited voltage and ampere. Let's see how S10 will improve the charging speed.
QC2.0 18W and USB PD 15W are the only fast charge standards supported by the Note 9 Exynos afaik.
It is not possible as Samsung has installed security features to prevent the Note 9's battery to prevent it from overheating.

Does Mi A2 support the new 27W Mi Sonic charger in India?

The indian variant supports QC4+, but the sonic charger has max output of 5V/3A,9v3A etc while the 18W qc3 max output is 5v3A, 9v2A etc.
Output is max 3Amps, so will it charge A2 any faster than the 18W Mi QC3 charger?
Sonic - http://m.store.mi.com/in/item/3192900008#specs
18W QC3 - https://m.store.mi.com/in/item/3192700003
Not sure if the "sonic charger" works faster than an 18w one as I use a 30W Anker PowerPort Atom PD1 that does USB-C PD - My MI A2 charges very quickly with this and it does standard USB-C PD - it also charges by USB C laptop as well.

Charger for mi note 10

Does anyone know of a good UK charger that would fast charge a Mi note 10. Its 30 Watts (10v 3a) I believe.
Thank you.

If you can buy Anker quick charge 3, USB c to USB c charger is very fast
I'm a bit puzzled myself regarding the suitable charger for the Mi Note 10.
Xiaomi specs say: "Supports 30 W charging. Packaging includes an 30 W charger"
Well, the phone runs Snapdragon 730G in which specs say: "Qualcomm® Quick Charge™ Technology Support: Qualcomm® Quick Charge™ 4+ technology"
So I'm not sure which charger should I buy.
QuickCharge 4 charger? 30W charger?
Helppppppppp
Help with the charger anyone?
Do I need to buy a QC4 charger?
