Abstract: Provided is an electronic device configured to be charged with an adapter. The electronic device includes an energy storage unit, a charging unit and a switch unit. The charging unit is configured to receive a bus voltage and output a charging voltage to charge the energy storage unit. The switch unit is electrically coupled in parallel to the charging unit. When the electronic device is coupled to the adapter through a bus interface, the electronic device receives the bus voltage from the adapter, receives a communication signal from the adapter, and selectively turns on or off the switch unit according to the communication signal, and when the electronic device operates in a direct charging mode, the switch unit is turned on to form a direct charging path, to charge the energy storage unit by using the bus voltage.
