A portable hand held power inverter/converter having a pass through device for simultaneously sourcing A.C. and multiple voltage D.C. power consuming devices through a single D.C. power source connection. Inverter and converter circuitry is provided to invert and convert D.C. voltage to an A.C. voltage source and a lower DC voltage. A.C. electrical outlets are provided to facilitate a connection to an external A.C. power-consuming device and a DC outlet to a lower volt DC power-consuming device. The pass through device provides an independent and simultaneous connection to an additional D.C. outlet that would otherwise be eliminated when occupied by the inverter thus allowing simultaneous connection and operation of both A.C. and multi source D.C. power consuming devices through a single external D.C. power outlet of a single D.C. power source.
