Abstract
A wireless charging circuit for power bank and a power bank thereof are provided in the present invention. The wireless charging circuit includes a boost DC to DC converter, a unidirectional conductive element and a wireless power converter. The input terminal of the boost DC to DC converter is coupled to the battery to receive the battery voltage. The output terminal of the boost DC to DC converter outputs a converted DC voltage. The first terminal of the unidirectional conductive element is coupled to the battery to receive the battery voltage. The input terminal of the wireless power converter is coupled to the second terminal of the unidirectional conductive element. When the wireless charging circuit performs the detection for the wireless power receiver, the wireless power converter disables the boost DC to DC converter.
