An automatic detecting and switching vehicle charger having a power control circuit is disclosed. A power supply control circuit is connected to a positive electrode clip and a negative electrode clip for supplying power to a battery of a car; a conductive end of the positive electrode clip being further connected to an input end of the power supply control circuit through a signal conductive wire. The power supply control circuit is formed by a power supply unit, a parallel connected relay unit, a serial connected relay unit, a fault detection unit, a low level positive voltage detection unit, a high level positive voltage detecting unit, a reference voltage unit, an alarm unit and a state display unit. In that, the power sources are switched automatically and thus the user is unnecessary to prepare a plurality of batteries as standby devices.
