See Also: Best RV AC Units Reviewed (13,500 & 15,000 BTU) The main thing to remember is that 12V air conditioners aren’t as powerful as standard 120 volt ones and they are going to perform best in smaller spaces like a van, truck camper, small trailer, or cabin.Ĭheck Price at Amazon 12 Volt Air Conditioner Reviews Douglas D20 Rooftop 12V Air Conditioner In this review, I’ll go over a few 12V AC units that can be powered using deep cycle batteries and even a swamp cooler that can be powered using the 12 volt outlet in your car. The Douglas D20 rooftop 12 volt air conditioner is as close as you can get to a traditional RV AC. It has the highest cooling capability in this review at 9,800 BTU. It is mounted to the roof and can fit in a standard 14×14 inch square hole that is often found in RVs.Ī standard 120V RV AC is normally 13,500 to 15,000 BTU. If you are installing it on the roof of a van or truck you will only need to drill four 2.8 inch holes for the air intake and outlet. There’s an inner panel that’s mounted to the ceiling inside that covers the air intake and outlet holes and also has the controls you use for setting the temperature. This is a non-ducted air conditioner which means the air will only come out from the vents on the inner panel. I recommend mounting it in a central location in your van or camper. The rooftop unit weighs 11o lbs and measures 32.7 inches long, 24.8 inches wide, and 7.6 inches tall.Īll the basic installation to the roof is pretty standard and straightforward. The 12V air conditioner will then be connected directly to a 12 volt battery via the included cables. The battery powered system makes this air conditioner a lot more simple to wire than a 120 volt one. The maximum current it’s rated to draw is 48 amps on a 12 volt system.

If you have an AGM battery that has a 100 ah capacity like this one by Renogy (click to view on Amazon) you will be able to run this 12V AC for around 1 hour at full speed.
