Patent ID: 8212386

Claim:
A power supply system configured to power a plurality of portable electronic devices, the power supply system comprising: a power circuit adapted to generate a first output voltage and a second output voltage at the same time; and an output connector coupled to the power circuit, wherein the output connector includes a plurality of electrical contacts including a first set of contacts adapted to provide the first output voltage and a second set of electrical contacts adapted to provide the second output voltage at the same time as the first output voltage, the first and second sets of contacts being different, wherein the output connector is adapted to connect to a first connector configured to connect to and be detachable from the output connector and electrically couple to the first set of contacts to provide the first output voltage to a first electronic device, wherein the first connector is further configured to connect to a first port of the first electronic device, and wherein the output connector is adapted to connect to a second connector configured to connect to and be detachable from the output connector and electrically couple to the second set of contacts to provide the second output voltage to a second electronic device, wherein the second connector is further configured to connect to a second port of the second electronic device, and wherein the system comprises the first connector and the second connector, and wherein the first set of contacts and the second set of contacts share a common ground line.
