1. A portable power supply, comprising:
- a direct current (DC) voltage supply input connector configured to receive DC voltage from a DC voltage supply;
an alternating current (AC) voltage supply input connector configured to receive AC voltage from an AC voltage supply;
an output connector configured to couple to an electrical device to provide power to the electrical device;
a voltage controller having a first input coupled to the DC voltage supply input connector to receive the DC voltage and a second input coupled to the AC voltage supply input connector to receive the AC voltage, an output coupled to the output connector, a switch controller, a first switch for connecting and disconnecting the first input to the output to supply the DC voltage to the output, and a second switch for connecting and disconnecting the second input to the output to supply the AC voltage to the output, wherein the switch controller selectively closes and opens the first and second switches to connect and disconnect the first and second inputs to the output.

Abstract
The present disclosure is directed to a portable power supply system for providing power to corded power tools. The portable power supply is configured to receive AC power through an AC power connector from an AC power source and DC power through a DC power connector from a DC power source. The portable power supply is configured to selectively provide the AC power and the DC power to a power supply output. The AC power and the DC power may be provided simultaneously or alternately to the power supply output.
