I have taken 18v cordless and hot wired them to 12 v.
Before the proliferation of cordless drills, we Used to carry one in the truck tool box with a heavy gauge wire and a lighter plug on it.
With the lighter plug, we could even run it off the jump pack

Used it more than once. It paid for itself every time and if had ever gotten stolen... Oh well.

I have 2 laying around, a 12volt and a 14.4. I keep them because I figure they could be used on an attachment, for instance you could gear one up to turn a snowblower chute. They are geared down pretty low on a 2 speed type drill and have enough torque to do some work.

I've thought about that and can't come up with a decent packaging.
