I saw this and though neat, then I started working out some numbers if you ran it on 12V power. start up 400amps for 150ms , cooling 84 amps , heating 74 amps. now these are maximum numbers but are you only useing this plugged in? or are you towing a trailer with a huge battery bank and fold up awnings on each side loaded with solar panels.
I don't have AC in my camper so I am not sure what that takes but in my 5th wheel I can run it if I am luckey on a 15 amp circut some times , so I imagin it is surging to 18ish amps on start up. so this is more efficient than normal ac units, but this is a little over 1/2 the output of a 13.5btu ac unit at 8200 btu, and for heat it is only 5797btu. so how long will it have to run to do a simluar job or will it even keep up? I like the idea of a heat pump though if you going to be plugged in, but for heat in the fall I don't think you can beat the good old propane furnace using a whopping 2.9 amps of 12V.
