Abstract

A notebook capable of wireless charging has a main body including a sensing element with a transmitter circuit. An electronic device with a receiver circuit to be charged is positioned on the sensing element. The transmitter circuit is configured to send an AC signal in a wireless way to the receiver circuit for charging a rechargeable battery of the receiver circuit. Thereby, various electronic products can be charged simultaneously without using different dedicated chargers. Also the limitation caused to the practical use of the notebook by wired charging through a charger can be eliminated.
