A wireless charger is a charger that does not use a traditional charging power cord to connect to a terminal device that needs to be recharged. It uses the latest wireless charging technology to transmit electrical energy by using an alternating magnetic field between the coils, inductive coupling technology will serve as a bridge between the charging base station and the equipment. 

The wireless charging technology, which received 20 patents in 2007, allows multiple devices to use a single charging base station, eliminating the need for wired charging of phones, MP3 players, power tools and other power adapters.
