The receiving coil 111 may receive a wireless power signal from a wireless transmitter ('wireless charging power supply').

The rectifier 112 is connected to the output terminal of the receiving coil 111 and can rectify the radio power signal to generate the first charging power. For example, the rectifier 112 may be connected to the output terminal of the receiving coil 111 to flatten the radio power signal to a DC voltage. Here, the first charging power means a power suitable for charging the batteries 142, 143, and 144.
