ECN Forum Forums General Topics of the Trade General Discussion Area Cordless tools, milwaukee or dewalt?

I prefer Milwaukee, and I see that thay have a 1-hour charger for the truck's cigarette lighter. Does anyone have one?
I think it's a good idea, and I will probably buy one.
I believe that an auto battery is typically 70 amp-hours.
This charger would be OK to run without draining the battery, but I'm going to look at the wattage of my 120 volt charger to be sure.
