Abstract: An electric device in one aspect of the present disclosure comprises a connector, a power supply unit, a connection-detection unit, and a control unit. The control unit is configured to control electric power supplied to the power supply unit from a battery so as to increase electric power supplied to the power supply unit when the connection-detection unit detects that an external device is connected to the connector.
