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.

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.
