The invention relates to a power protection and automatic control repeater, and the repeater is formed by the series connection of an overcurrent protection unit, a remote control unit and a power supply socket unit. The overcurrent protection unit is formed by the connection of an overcurrent protector and a power indication lamp. The remote control unit is formed by the connection of a wireless remote control device and a work indicating lamp. The repeater integrates the functions of power failure remote control and power overcurrent protection, can achieve the switching of remote complete disconnection or connection of power utilization equipment and a power supply, also has a function of electric leakage protection, and can effectively reduce the risk caused by a short-circuit fault to electronic equipment, especially a power adapter.
