Wireless reverse charging means that devices that can only receive wireless charging electromagnetic waves, such as mobile phones, can now charge other devices that support wireless charging through wireless coils. It should be noted that its charging power is small and can only be used as an emergency. At the same time, the receiving device needs to comply with the QI wireless charging protocol and be placed in the center of the back of the mobile phone, and do not place metal substances between the receiving device and the phone.
This means that your mobile phone can charge another mobile phone that supports wireless charging, which is equivalent to trying your mobile phone as a charging bank
