Wireless reverse charging refers to the mobile phone and other devices that can only receive wireless charging electromagnetic waves, and now can emit electromagnetic waves through the wireless coil to charge other devices that support wireless charging. That is to say, this function is only the omnidirectional support of the wireless charging function, that is, it can not only receive electromagnetic waves, but also release electromagnetic waves, so as to output electricity in reverse
The principle of counter-charging is: the battery output charge drives the motor to rotate (converts electrical energy into mechanical energy) when the motor drives the bearing to rotate, it also drives a coil to rotate in a magnetic field to generate electric charge (converts mechanical energy into electrical energy) to charge the battery.
