Abstract: A charging adapter in one aspect includes a first coupler, a second coupler, a power delivery path, a converter, a communication circuit, a charging control circuit, a control power supply, a first switch, a first internal path, a second internal path, a second switch, and a starter circuit. The charging control circuit performs a charging control of a battery pack. The charging control includes switching the converter to a first state or a second state. The converter in the first state receives a DC voltage from a power delivery adapter through the first coupler, converts the DC voltage into a charging voltage for charging the battery pack, and outputs the charging voltage to the second coupler. The converter in the second state receives the DC voltage from the power delivery adapter through the first coupler and outputs the DC voltage to the second coupler.
