Abstract

An electronic device includes an interface unit to which external devices can be connected, and a control unit. The control unit sets power to a second power greater than a first power after limiting power supplied to the external device to the first power, maintains power supplied to the external device at the second power, in a case where the number of the external devices connected to the interface unit exceeds a predetermined number, and controls power supplied to the external device to be a third power greater than the second power, in a case where the number of the external devices connected to the interface unit is not the predetermined number.
