Has anyone created a battery pack that also has a power cord socket built into it? Answered
What I want to try and do is to mate a standard 3 prong power cord socket into a battery pack that can be used on a impact drill, circ saw, etc. Has anyone tried this before? Is there some sort of special switching circuitry that would be needed other than a step down transformer and a bridge rectifier? Also, how small of a transformer could I use for this setup?
The battery side of the setup would be used as a backup to the primary source (the power cord.)
