Wireless charger

A wireless charger (1) includes a coil (10) and a charging converting circuit (20) connected to the coil (10). The coil (10) is integrated into a battery (2) and capable of receiving electromagnetic energy. The received electromagnetic energy is converted into electrical energy by the charging converting circuit (20) and then transmitted to the battery (2). By way of integrating the coil (10) into the battery (2), it is not required to change the existing structure of an electronic device, but only the structure of the battery (2) in the electronic device. This saves costs and facilitates the popularization of wireless charging.
