US 2013/0076155 A1 · Electronic Device and Power Supplying Method and Wireless Power Supplying System Thereof

Abstract

An electronic device, and a power supplying method and a wireless power supplying system thereof. The electronic device includes a wired electric power receiving module, a wireless electric power receiving module and a switch. The wired electric power receiving module is connected to an external power supply by wired transmission. The wireless electric power receiving module receives the wireless electric power from an external wireless electric power transmitting device. The switch is coupled to the wired electric power receiving module and the wireless electric power receiving module and is used to switch between the wired electric power receiving module and the wireless electric power receiving module, to supply the operating voltage. The electronic device can operate in the wireless power supplying mode or the wired power supplying mode, so as to facilitate a user to use.
