The present invention discloses a power adapter has a power converter, a power output cable, a first DC power connector and multiple second DC power connectors. The power converter has a casing, a power converting circuit mounted in the casing, and an AC power inlet and DC power outlet electronically connected to the power converting circuit. The power output cable has a DC output and selective connector having two DC power pinholes and multiple selective pinholes surrounding the two DC power pinholes. The first DC power connector has two DC voltage pins and is selectively connected to the DC output and selective connector. Each of the second DC power connectors has a body, a DC plug formed on the body, two DC voltage pins formed on the body and one jumper pin formed on the body and corresponding to the selective pinholes of the power output cable to change voltage of the DC power output from the power converting circuit.

A universal series bus (USB) power supply has a DC power source, a USB power interface and a voltage modulation module. The USB power interface is for connecting to an electronic device that stores a default D+ voltage and a default D&#x2212; voltage. The voltage modulation module connects to and outputs signals to the D+ and D&#x2212; terminals of the USB power interface. If voltage levels of the output signals are not respectively identical to the default D+ and D&#x2212; voltages, the voltage modulation module changes the voltage levels of the signals output to the D+ and D&#x2212; terminals of the USB power interface until the voltage levels of the output signals are respectively identical to the default D+ and D&#x2212; voltages. Therefore, the USB power supply may be applied to any kind of electronic device that is charged over a USB interface.

Universal USB power supply

An electrical adapter assembly has a cable and an adapter. The cable has a distal end having a plug and a proximal end having a connector. The connector comprises a shell having an inner space, a first end and a second end having an output hole allowing the cable to be mounted in the inner space. The second end of the connector has an outer surface, a positive electrode, a negative electrode and a thermal sensor mounted in the inner space of the connector. The adapter connects to the cable and has a circuit board and a socket corresponding to the plug. Because the thermal sensor can sense the temperature in the connector and cut off the current when the temperature is too high, the cable will not be damaged and users will not be in danger.
