Abstract

A wireless power transmission system is provided, which includes a power supplying device and a power receiving device. The power supplying device electrically connects to an outside supply terminal and has a wireless transmission module. The power receiving device has a wireless receiving module. Wherein, the power supplying device connects to the wireless receiving module via the wireless transmission module and transmits a power from the outside supply terminal to the power receiving device, after the power supplying device detects the wireless receiving module via the wireless transmission module. Alternatively, after the power receiving device detects the wireless transmission module via the wireless receiving module, the power receiving device connects to the wireless transmission module via the wireless receiving module so as to receive the power transmitted by the power supplying device.
