Abstract
A power apparatus includes an input interface, an output interface, a detect unit, a warning unit and a switch unit. The input interface is used for receiving a voltage of an exterior power. The output interface is used for outputting the voltage of the exterior power to an electronic device. The detect unit is used for detecting if the voltage of the exterior power is too high, and outputting a cut signal when the voltage of the exterior power is too high, or outputting a connection signal. The switch unit outputs the voltage of the exterior power through the output interface according to the connection signal. The switch unit won't output the voltage of the out power and the warning unit gives an alarm according to the cut signal.
