Abstract

The wireless charging device is provided for coupling and charging a portable electronic device, and the portable electronic device includes an input terminal, and the wireless charging device comprises an electric power transmitting module, an electric power receiving module, and an electric power transmission interface. The electric power receiving module can produce an electromagnetic effect with the electric power transmitting module, such that the electric power transmitting module outputs electric power to the electric power receiving module. The electric power transmission interface is electrically coupled to the electric power receiving module through a detachable electric power connecting module, and the electric power transmission interface can switch the electric power outputted from the electric power transmitting module to the electric power receiving module to charge the portable electronic device. The electric power transmission interface has an output connector detachably connectable to an input terminal of the portable electronic device.
