Abstract

Power supply equipment includes circuitry for converting an input voltage to first and second DC voltages provided at respective power ports. One of the ports is connected to a cable having a connector or connector adapter which has a shape and pin out compatible for detachably mating with a first electronic device. A second port is connected to a connector for receiving a cable for coupling to a second electronic device. The power supply powers the first electronic device at the first DC voltage and the second electronic device at the second DC voltage.

Claims (23)

1. Power supply equipment comprising:

an input terminal to receive an input voltage;

circuitry for converting the input voltage to first and second DC voltages, the first DC voltage being provided at a first power port and the second DC voltage being provided at a second power port, the first and second power ports being separately disposed from each other to provide separate external connection ports;

a first cable having a proximal end which is electrically connected to the first power port, a distal end of the first cable affixed with a first connector having a configuration, including shape and pin out, compatible for detachably mating with at least one particular model of a first electronic device; and

a second connector, electrically connected to the second power port, for receiving a first end of a second cable, a second end of the second cable for coupling to a second electronic device,

wherein the circuitry provides power sufficient to simultaneously power the first electronic device at the first DC voltage and the second electronic device at the second DC voltage.

2. The power supply equipment according to claim 1 including the second cable, the second cable having a proximal end connector which detachably mates with the second connector and a distal end connector which detachably mates with the second electronic device.

3. The power supply equipment according to claim 1 , wherein the first cable has a proximal end connector which detachably mates with the first power port.

4. The power supply equipment according to claim 1 , wherein the input voltage is an AC voltage.

5. The power supply equipment according to claim 1 , wherein the first electronic device is a laptop computer.

6. The power supply equipment according to claim 5 , wherein the second electronic device is a cellular telephone.

7. Power supply equipment comprising:

an input terminal to receive an input voltage;

circuitry for converting the input voltage to first and second DC voltages, the first DC voltage being provided at a first power port and the second DC voltage being provided at a second power port, the first and second power ports being separately disposed from each other to provide separate external connection ports;

a first cable having a proximal end which is electrically connected to the first power port, a distal end of the first cable affixed with a first connector;

a connector adapter having a first plurality of contacts and a second plurality of contacts disposed in a single housing with at least two contacts in the first plurality of contacts being electrically connected to at least contacts in the second plurality of contacts without a cable disposed between the first plurality of contacts and the second plurality of contacts, the first plurality of contacts being detachably mateable with the first connector, the second plurality of contacts having a configuration, including shape and pin out, compatible for detachably mating with at least one particular model of a first electronic device; and

a second connector, electrically connected to the second power port, for receiving a first end of a second cable, a second end of the second cable for coupling to a second electronic device,

wherein the circuitry provides power sufficient to simultaneously power the first electronic device at the first DC voltage and the second electronic device at the second DC voltage.

8. The power supply equipment according to claim 7 including the second cable, the second cable having a proximal end connector which detachably mates with the second connector and a distal end connector which detachably mates with the second electronic device.

9. The power supply equipment according to claim 7 , wherein the first cable has a proximal end connector which detachably mates with the first power port.

10. The power supply equipment according to claim 7 , wherein the input voltage is an AC voltage.

11. The power supply equipment according to claim 7 , wherein the first electronic device is a laptop computer.

12. The power supply equipment according to claim 11 , wherein the second electronic device is a cellular telephone.
