The Cool Cat runs off 120V AC. As pointed out, using it to heat with outside temps below 40 won't work, and may lead to part of the Cool Cat freezing up. The electronic thermostat that controls both heater and Cool Cat takes a very small amount of 12V DC.
The heater fan is a 12V DC fan that draws about 4 amps in operation. If your battery is good, it will run the heater for 2 nights (5 hrs run time per night) without taking the battery below 50%. I have 2 batteries to extend run time without hookups to 4 nights.
On our last trip to the Black Hills we had nights in the high 30s and low 40s. The thermostat was set at 60, and the fan ran about 3 hours each night (10 minutes on, 20 - 30 minutes off). The composite roof and sides, and much smaller volume of air make the heater pretty efficient compared to other campers.
