Abstract

An auto-rechargeable wireless computer peripheral includes a wireless power supply module and a wireless receiving module. The wireless power supply module is used for transmitting an electromagnetic wave. The wireless receiving module is corresponding to the wireless power supply module, for receiving the electromagnetic wave, converting the electromagnetic wave into an electric power, and storing the electric power. When the electric power stored by the wireless receiving module is lower than a rated value, the wireless receiving module outputs a charging signal, and the wireless power supply module receives the charging signal and transmits the electromagnetic wave in response to the charging signal, so as to automatically charge the wireless receiving module.
