I’ve checked the dremel website no power levels. I’ve got to dremel some holes in the dash and solder up some connections and cause I can’t be bothered to run an extension cord out one at to use a can sized inverter rated to 150w/300w peak. My soldering iron is 15-40w so that’s easy. Pretty sure a dremel should be under 150w just making sure really. As a bonus can just leave stuff in car instead of packing it up.
