Abstract
An electronic device and a power adapter are provided. The power adapter comprises a power circuit, a main control circuit, a potential adjustment circuit, a current detection circuit, a voltage detection circuit and an output switch circuit. When a conventional charging or a quick charging is performed on the battery in the electronic device, the main control circuit determines whether the output current of the power adapter is greater than a current threshold according to the current detecting signal and determines whether the output voltage of the power adapter is greater than a voltage threshold according to the voltage detecting signal; if the output current of the power adapter is greater than the current threshold and/or the output voltage of the power adapter is greater than the voltage threshold, the main control circuit controls the output switch circuit to turn off the direct current output of the power adapter.
