Wireless charging technology

Wireless charging technology originates from the technology of wireless electric power transmission which uses magnetic resonance to transmit charge in the air between charger and equipment while coils and capacitors form resonance between charger and equipment to realize efficient transmission of electric energy. It makes use of the principle of electromagnetic wave induction and related AC induction technology. It is a technology that uses the corresponding coil at the sending and receiving end to transmit and receive the AC signal that generates the induction for charging. Users simply put the charging device on a "tablet" to charge.
