Abstract
A portable charger includes: an AC input unit; a DC output unit; a power conversion circuit; and a controller. The DC output unit includes a start switch. When the start switch is operated by a user, the start switch instructs the controller to control the power conversion circuit such that the DC output unit outputs DC power. However, when at least one of the AC input unit and the DC output unit is unconnected, the start switch is disabled.
