Abstract

A portable 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.

Claims

1. A multi source power converter device comprising:

a housing;

a first electrical connector for connecting said multi source power converter device to a first external D.C. voltage source;

a circuit assembly supported within said housing and electrically coupled to said first electrical connector to facilitate a connection to said first external D.C. voltage source, said circuit assembly comprising an inverter circuit equipped with electrical components for inverting said first external D.C. voltage source to an A.C. voltage source and an additional converter circuitry to convert said first external DC voltage source to a second lower voltage DC power source;

an A.C. electrical outlet connected to said housing provided to facilitate a connection to an external A.C. power consuming device, said A.C. electrical outlet being powered by said A.C. voltage source when said first electrical connector is connected to said external D.C. voltage source;

a DC electrical outlet connected to facilitate a connection to an external DC power consuming device, said DC electrical outlet being connected to and powered by said second lower voltage DC power source from said converter circuitry; and

a pass through device having a pass through D.C. electrical outlet to facilitate a connection to and providing said first external D.C. voltage source to an external D.C. power consuming device when said first electrical connector is connected to said external D.C. voltage source.

2. The device according to claim 1 wherein said first external DC voltage source is a 12 volt DC power source and said second lower voltage DC power source is a 5 volt power source, said inverter circuit inverting said 12 volt DC power source to an alternating current power source and said converting circuitry converting said 12 volt DC power source to said 5 volt power source.

3. The device according to claim 2, wherein said first electrical connector is a male plug connector adapted to mate with a female socket of said external D.C. voltage source, said D.C. electrical outlet is a female socket correspondingly dimensioned to accommodate said male plug connector thereby mirroring said female socket of said external D.C. voltage source.
