1. A portable charger comprising:
an AC input unit connectable to an output unit of a power supply facility, the AC input unit receiving AC power from the output unit of the power supply facility;
a DC output unit connectable to a power reception unit of a power supply target, the DC output unit outputting DC power to the power reception unit of the power supply target;
a power conversion circuit that converts the AC power input from the AC input unit into DC power and outputs the DC power to the DC output unit;
a controller that controls the power conversion circuit, wherein
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 the DC power, and
when at least one of the AC input unit and the DC output unit is unconnected, the start switch is disabled, and
a lock mechanism that switches the start switch between a locked state and an unlocked state, the locked state being a state in which operation of the start switch by the user is restricted, the unlocked state being a state in which operation of the start switch by the user is permitted, wherein
when at least one of the AC input unit and the DC output unit is unconnected, the lock mechanism brings the start switch into the locked state, thereby disabling the start switch.
