A wireless charging method of the present invention is applied to a wireless computer peripheral device. Firstly, the access points that are able to emit wireless radio waves and located near a computer are searched by the computer. After a target access point is selected, the connection information about the target access point is transmitted to the wireless computer peripheral device. According to the connection information, the connection between the wireless computer peripheral device and the target access point is established. Consequently, the charging signal can be acquired by the wireless computer peripheral device, and the wireless charging operation will be performed. By the wireless charging method of the present invention, the wireless charging feasibility and convenience will be enhanced.
