Protection of a protection target instrument such as a vehicle-mounted battery is safer in a charger that charges a vehicle-mounted battery. First and second detection means and first and second forced stop means described hereafter are provided in a charger including an AC/DC converter having a PFC circuit that converts alternating current power supplied from an external alternating current power supply into direct current power and a smoothing capacitor, and a DC/DC converter that transforms power output by the AC/DC converter and supplies the transformed power to a vehicle-mounted battery. The first and second detection means detect voltage applied to the vehicle-mounted battery. The first forced stop means determines whether or not voltage detected by the first detection means exceeds a predetermined threshold, and causes the DC/DC converter to stop when the predetermined threshold is exceeded. The second forced stop means determines whether or not voltage detected by the second detection means exceeds the threshold, and causes the DC/DC converter to stop when the threshold is exceeded.
