I took the battery out of my pop-up camper and hooked it up to that, it's just a 12v AGM deep cycle. These things don't require a lot of power but I wanted a dedicated battery to it. Power requirements are the glow plug when it first starts and then just the fan. We were out there I think 7 nights, don't know how long it would last alone as I hooked up a 100w solar panel to it so it was pretty much fully charged every evening. We had a couple days straight of heavy snow and overcast without any power issues and battery voltage was still plenty high. Testing at home I ran it off of my Jackery 1000 with the A/C adapter and it ran well for a few hours testing. Cigarette lighter plug would throw some low voltage errors though when I tried to use that.
