ABSTRACT:
A multiple output AC/DC power adapter is provided. The adapter includes an adapter body with an output connector and more than one output plugs configured for connecting with the output connector. The adapter body includes a DC-DC converting circuit having an input terminal, an output terminal, a first adjustment terminal. The output connector includes a positive terminal, a second adjustment terminal and a negative terminal configured for connecting to the output terminal and the first adjustment terminal of the DC-DC converting circuit and ground correspondingly. The output plugs each includes an adjustment resistor having a resistance value different from the other output plugs. Therefore, when equipped with a plurality of output plugs each of the plurality of plugs having different resistor R0, the adapter can supply different output DC voltages for different electronic device.
