What is the principle of wireless charging?

The wireless charging system mainly uses the principle of electromagnetic induction.

Wireless chargers refer to chargers that do not use traditional charging power cords to connect to terminal devices that need charging. They use the latest wireless charging technology and use the magnetic field generated between coils to achieve magical transmission. Electric energy and inductive coupling technology will become a bridge connecting charging base stations and equipment.

Wireless charging technology obtained 20 patents in 2007. Multiple devices can use one charging base station, and wired charging of mobile phones, MP3 players, power tools and other power adapters will no longer exist.
