Abstract
An electrical apparatus includes a main unit which consumes electrical power; a power supply unit which supplies electrical power from a commercial power source to the main unit; a secondary battery to be charged with electrical power supplied from the power supply unit; and a power source control unit. In a state where a power source of the main unit is the power supply unit, when power consumption of the main unit exceeds a first threshold, the power source control unit changes the state to another state where the power source of the main unit is the power supply unit and secondary battery.
