They run on 240v, so you better have some seriously beefy batteries with an expensive 12v to 240v inverter. You are probably better off with the Coleman roof-mount AC.
I’m wanting to do some seriously back country camping on family owned land on a vacant mobile home pad with well and septic. I don’t want to run power to it. Well pump can be easily run with it’s own panel, and easily decontaminated since it’s been unused for years. Septic doesn’t require power in and of itself. I’d want off-grid, for that reason and possibly others.
