Yes, extra juice when camping. Also, when doing a long drive, we had to stop in a cheap hotel sometimes and keep the fridge running overnight. Also for camping and in addition, an extra battery to jump start it if my primary battery fails. Also, i have another old 4th gen that i use, I can move it between which suv i want to use.

I like the idea, leave at home when not using it, take it with me when camping or something.
