Using tool at home made to work in cigarette socket?
Search for 120V 12V cigarette lighter adapter. If your home electricity is 240V (i.e., most places outside USA/Canada) then look for 240V 12V cigarette lighter adapter. Some adapters will, like laptop chargers and other equipment, handle a range 110V - 240V, 50/60 Hz.

You'll find more of the reverse (to run 120VAC equipment using your car's 12VDC) but there are plenty like this adapter on Amazon. I recommend getting one that is UL listed if possible and make sure it can supply the power (watts) your tools need.
