Power tool battery inverter from Millertech. Works with Dewalt and Milwaukee batteries. It's not advertised to work with Hercules and the Hercules batteries don't click in with their release lever but they do work and stay in pretty well with friction.
In the video I mistakenly refer to the YouTube source for this product as LSD reliance. It's actually LDSReliance.
