Abstract

A wireless power supply device is adapted to a main body of an electronic device. The main body of the electronic device defines a power receiving compartment where the wireless power supply device is received. The wireless power supply device includes a wireless power receiver having a circuit board and a sensing coil. The sensing coil is disposed on and electrically connected to the circuit board, and the circuit board has two wires. The wireless power supply device also includes a shell conforming to the power receiving compartment. The shell has an anode portion and a cathode portion, the anode portion corresponds to an anode in the power receiving compartment and the cathode portion corresponds to a cathode in the power receiving compartment. The two wires respectively connect to the anode portion and cathode portion of the shell.
