I am always fantasizing about having a energy efficient air conditioner for van life, anyone seen any concepts in tech news or anything?

Anyone record real numbers?
Advertising always gives an amp range, but is that with compressor running, or just the fan? For me the compressor runs 20% of the time, so I would need calculate amps also with just fan running. I kinda hit a brick wall not knowing specifics when shopping...

Most efficient inverter driven units run the compressor all the time, but at lower levels of power so the result is the same without the start up surge. I suppose that is one way they achieve the higher efficiecy numbers.
