A portable phone charger for shutting off standby power is provided, in which a standby power shut-off unit is provided at a predetermined position within a jack, and brings one contact point and the other contact point of an AC power cable into contact or separates the contact points from each other to shut off standby power from the portable phone charger, and a controller measures current flowing through the portable phone charger, determines whether standby power is generated in the portable phone charger by comparing the measured current with a reference current, and supplies power to the standby power shut-off unit to separate the one contact point from the other contact point, upon sensing the standby power. |
