Abstract
An AC adaptor with a replaceable protection device is provided. The AC adaptor includes a main body at least having a power supply casing and a recessed socket on the power supply casing, and a protection device inserted into the socket. The protection device includes a casing, a plurality of metal pieces therein, and a resistor device connected the metal pieces. By changing different resistor devices, the resistance of the protection device changes accordingly; as this result, the AC adaptor is capable of providing different output voltages.
Claims6
