[Q] Reverse charging specification

[ColorSage]

Hello.
As I have already mentioned it one or twice I use my phone from time to time to charge other devices. The maximum speed I get is 500mA/5V for other phones and up to 870mA/5V while charging JBL Flip 4. These are typical charging rates using OTG adapter (<5W). In some reviews it is said to support up to 10W Reverse charging which is 2x my maximum charging ever measured. Is it really 10W or it's some kind of error? If not, how can I achieve faster charging rates? I'd expect something around 1.5A/5V.

Hi
ZenFone 6 does not plan reverse charging function, it is not encouraged to use it~


請問Zenfone 6 有支援反向充電嗎
If you still insist on using reverse charging, 5V/0.5A is normal.

This is interesting as person from Asus already stated above it doesn't. How did you achieve that output?
