Hi Shepard, the 12V curing lamp I use plugs into a clamp attachment for a 12V motorcycle battery that measures about 6"x4" and fits neatly in my toolbox and isn't heavy at all. I've been using the same battery for a couple of years and only needs recharging every 6 months or so. Though I didn't get a warranty on the battery when purchasing because it wasn't being charged all the time as it would in a motorcycle I didn't need it anyway - it still works like a charm!
