Abstract
Power supply equipment is provided with two power ports for simultaneously powering two electronic devices. The equipment includes low power assemblies and high power assemblies, each of which is detachably mateable to either one of the power ports. To simultaneously power two low power devices, low power assemblies are respectively mated to each of the power ports. To simultaneously power one low power and one high power device, a low power assembly is mated to one of the power ports and a high power assembly is mated to the other power port. The low power assemblies transfer a low DC voltage, but not a high DC voltage, to low power devices. The high power assemblies transfer a high DC voltage, but not a low DC voltage, to high power devices. If a high power assembly is mated to each of the power ports, power flow is interrupted without putting supply in an overvoltage or overcurrent condition.
