Portable Power Supply

摘要

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.
