WELL,,, 4runners are kinda small and i carry a jet boil but it kinda sucks to heat stuff on it,,,even with the little pot adaptor. it just gets to hot so if you try to heat up some pre-cooked breaky or even beans and meat for a burrito,,, it just burns it and messes up the pot. so i just thought there might be a little micro out there but the all seem to be 700w for the smallest and like the gent above said,,, probably need a way bigger inverter. so it is not that i want it fast,, i just don't want to burn it and putting in the old coleman stove,, it's kind of big and takes up a lot of room so...just trying to think outside the box
