Patent ID: 8519564

Claim:
An apparatus for providing power to an electronic device, comprising: a power input configured to receive an input voltage from a power supply; a rectifier operatively connected to the power input and configured to convert the input voltage to a first voltage; a first power output connector operatively connected to the rectifier, wherein the rectifier is further configured to transmit the first voltage to the first power output connector; a power converter operatively connected to the rectifier and configured to convert the first voltage to a second voltage different than the first voltage; a second power output connector operatively connected to the power converter, wherein the power converter is further configured to transmit the second voltage to the second power output connector; and a first relay operatively connected to the rectifier to selectively prevent the first voltage from being transmitted through the first power output connector, wherein a state of the first relay is determined at least in part by a state of a first control line, wherein the first control line does not transmit the first voltage, wherein the first relay includes a first logic configured to determine whether a first electronic device operatively connected to the first power output connector is compatible with the first voltage.
