Super charge and cable not genuine

Hello. I tried charger qc 3.0 but doesn't work at speed fast... I tried the genuine charger with a tested cable hi speed 3.0 and doesn't work at speed... Can anyone suggest a charger and a cable tested working lower yhan 10 dollars shipped??? Its incredible this price difference with qc that i bought both 3 dollars
Use original cable and charger ro charge at high speed... Other cables or chargers don't work and can even damage your phone..
(for example my umi fast charger usb C..
charges at 5+9+12volts)
With a cheap price always comes cheap quality.
QC 3/4 are not built for the Mate 10 series, they are built for QC compatible devices, while it will still charge the phone, probably at slightly increased speeds - you won't get the full power out of it as, its not meant to be used on a Fast charge phone (Fast charge / SuperCharge whatever Huawei call it)
Let me share something which I've found out recently. If you use a QC charger for eg. Xiaomi Type C Mi Power bank Pro which support QC 3.0 charging, my Mate 10 will display "Fast Charging" which is definitely faster than normal "Charging". If you use the Huawei Supercharge AP09S Power bank, it will charge at the max rate "Super Charging"
Huawei Supercharge is a dedicated technology just like qualcomm quickcharge. For it to work you need the dedicated hardware.
Most important: Huawei Supercharge phone and Huawei Supercharge power brick. Since supercharge features up to 5A current you will need a type c cable that supports 5A. Then you are good to go.
The Huawei phone of course supports standard USB protocols like 5V2A etc. But that's not fast.
Older Huawei/honor phones support Huawei quickcharge (what they used before supercharge) which is 9V2A. I think the mate 10 supports that too.
From my experience though the phone displays "charging" when connected to PC via USB. "Quickcharge" when connected to normal wall charger. "Supercharge" when connected to supercharge wallcharger (or supercharge car charger or supercharge Powerbank) via 5A (ampere) USB cable.

PD charger for Huawei P20 pro? Will it work?

I have PD charger 3 ports for charging my Pixel 2 XL and Iphone X, but now i have only P20 pro.
Just wondering if it will at least quick charge? or will it be as fast as the super charger (finger crossed)
or just simple normal charger.
If it works, i will buy the usb c to usb c cable since i only have usb c to lightning cable
Thanks
It will behave as a simple normal charger.
I have tested this DP charger and it gives "fast charging" which is a step up above normal charge but below "Super Charge" it will give an extra lightning bolt when charging to indicate this.

Is the P30 Pro compatible with Quick Charge 3.0?

Hi guys,
I just got a quinck charger 3.0 from Anker, the P30 Pro is saying it is in "Quick Charge" but it sometimes charge at 2.5A and often at 1.2A.
Do you know if there are some compatibility issues?
Thank you!
It is compatible, iv got a qc3 charger and it shows quick charging by 2 lightening bolts on the battery. Works with wireless quick change as well.

Thank you. It says quick charge, but it never goes up to 3A. it moves between 1.2A and 2.5A, that's why I'm not sure it works correctly.
I still use it with the fast charge cables (purple ones) I think they handle the power to them

Question Fast Charge compatible alternative cables/chargers?

Hey all, anyone found a working alternative to the default charger and cables?
I've tried a couple wall chargers and cables that supports more than 55w (11V/5A), but none of them seem to display the yellow, fast charging status.
I tried xiaomi power bank pro 3. Which support 45w and samsung wall charger also 45w. Both charge the phone with 28w. I guess if you take a look at the oem vivo charger its 10w and 18w and 33w and 55w. So its not capable of anything else. You should probably use a 33w (11v- 3A) it should be ok. Or (11v-5a)

Question Technical Question re:charging

I have both the x90 pro and 90 pro plus. origin os. interesting question because I feel that mixing and matching chargers doe not charge at the max speed of charger/unit. so, given same cable length of 6a cable (or same cable) :
would the vivo x90 pro 120w charger be able to charge the vivo x90 pro plus at 80 watts? and would the 80 watt vivo x90 pro plus charger be able to charge vivo x90 pro at 80 Watts?
I also posted this on this website(
). I just feel that they dont do so.
Just food for thought..thanks
The x90 Pro plus never charges above 60w... (mayb 10 seconds - but surely never for a full minute!) - can easily measure this with a powermeter. This does not matter if switched on or off.
Also even worse there is no hardware to stop charging - go into bootloade fully charged and leave it connected - phone will get very hot once fully chargd as vivo messed up something there.
And yeah it's hypersensibl based on the cable. Some cable charging my laptop at 60 watts (max speed for my laptop - actually on a 65w brick) will only give 3-10w. Others are better and allow 20w (the max for 3rd party chargers)

Interesting. I was wondering about the message "fully charged, remove immediately".. I mean silly .. what if you want to charge it overnight.. I have to say (again I don't have a power meter.. yet.. ),the x90 pro with 120 watts brick charges so so quickly ... Anyways thanks for the feedback .. ps:both units I disabled smart charging option or the option that learns your usage etc..
in bootloader it's worse than trickle charge - if phone is on or off it's trickle charge - in bootloader it's like 6-7w pushed in that need to get rid via thermals. It's really crazy vivo saved some pennies on hardware charge protection (on third party chargers at least - maybe the vivo charger brick that I don't use because it's way too big for the power has some inbuilt protection).
But clearly even on the own charger there is no like charge to 100% - go down to 97% - then shortcut the battery or similar. It's a great way to destroy the battery quickly though.
