Interesting. A lot more efficient than the Dometic 3 way fridge
I have, someone in another thread mentioned those using 10 amps on average. I won't be running that off 12V unless on the TV and the engine running.
60 amp hours a day = one dead 80 amp hour Group 24 battery
in less than 24 hours. 120 amp hour battery
dead in 24 hours.
80 amp hour battery
at 50% discharge 40 amp hours, or less depending on the discharge rate.
Still not good.
The 9 amp on 12 Volt 3 way is going to be worse, yes. That's why most never use the DC 12 position except maybe when driving with a tow vehicle that can handle that extra 9 amps.
