Abstract

Disclosed is a power device including a connector, a power supply unit, a switch unit, a connector-side voltage detector, a connection determiner, and a switch controller. A battery is detachably connected to the connector. The power supply unit is provided between the connector and external equipment. The switch unit is provided to change over between power supply and power cut-off state unidirectionally from the connector to the power supply unit. The connector-side voltage detector detects a voltage of the connector-side of the switch unit. The connection determiner determines whether the battery is connected to the connector on the basis of the connector-side voltage. The switch controller controls the switch unit such that electric power is supplied unidirectionally from the connector to the power supply unit when the battery is connected.
