Abstract: An electronic device is provided. The electronic device includes a connection interface, a boost-buck charger, a voltage converter, a boost-buck circuit, a power control chip and a controller. The boost-buck charger is configured to provide a system voltage. The voltage converter generates a first charging voltage based on the system voltage. The boost-buck circuit includes a boost-buck converter. When the connection interface is coupled with an external device, the power control chip communicates with the external device through a power control protocol and enables the boost-buck converter to generate a second charging voltage, higher than the first charging voltage, based on the system voltage according to a charging requirement of the external device. The controller decides to provide the first charging voltage or the second charging voltage to the external device according to the charging requirement of the external device.
