Portable hybrid applications for AC/DC load sharing includes circuitry for simultaneously using at least one of external AC, internal DC power and/or external DC power. The apparatus also includes an input power receptacle for receiving at least one of AC power and external DC power. A power router inside the apparatus routes at least one of AC power, internal DC power, and external DC power to provide power for an application. An apparatus for providing DC to DC conversion includes a tip and a DC to DC whip connected to the tip. A male plug is connected to the second end of the whip. A buck converter within the male plug converts DC power to a DC power level associated with the whip and transmits the converted DC power along the DC to DC whip to the tip. Alternatively, an internal DC source provides internal DC power.
