Wireless backcharging refers to a wireless charging technology that allows devices to transmit energy through wireless electromagnetic waves between each other without having to plug in any cables or touch the charger.
Specifically, the device charges by converting electrical energy into electromagnetic waves and sending them through wireless communication technology to the receiving device, which then converts the electromagnetic waves back into electrical energy. Wireless reverse charging technology can provide a more convenient way to charge mobile devices and electronic products, but its charging efficiency and speed still need to be improved.
The function of using the mobile phone as a mobile power to charge other devices, first connect the two mobile phones with the OTG line and the mobile phone data line, and then change the USB connection mode in the notification bar to reverse charging on the mobile phone at the power supply side. There is a premise here that the mobile phone at the power supply side supports OTG, and if the other mobile phone does not support reverse charging, the supported end will automatically supply power
Meaning: wireless reverse charging, the use of good effect, convenient and convenient.
