Wireless charging modules uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. It is using the new technology "resonant magnetic coupling, which will reduce the electricity consumption during power transmission. The transfer efficiency could arrive at 90%. It could meet your most project requests.
