12 / 24 volt air conditioner
Ok....so with so many boondockers going the mini split route to run air conditioning off batteries but on those not nights when you pull off the road or into a rest area and you don't want to run the ...

That aside the top AC units approach 20 for a EER, and that still puts you in the 50A range from 12V.
A quick look at the amazon units claim decent efficiency, 750W for 13Kbtu vs the 1400W for a rooftop RV, but still that's around 25A at 24V and it requires 50+A for startup.
Comparing a 12VDC A/C to a 12VDC compressor refrigerator (they are close cousins), all DC refrigerators that I know of actually take the DC voltage run it through an inverter and generate a 3 phase AC output (3 phase motors much more efficient than single phase).
It can be done, but is it the best solution from a total energy consumption standpoint ?
As pointed out, most mini-splits have a very high EER. There are a few "window shakers" that have similar EER.
