Seems that manufacturers abounded 12V elements once inverters become popular.
I remember removing the elements on 1980's fridge and when 120V element was like 110W rated, the 12V was 80W rated.
So 12V was not design to give equal cooling.
80W btw is 7.5 amp so you can calculate how long your batteries would support cooling at full blast.
I just had "nice" surprise on my household refrigerator. Even it is several years old, the inverter technology made into it.
Good thing inverter technology compressor gives better efficiency and quiet work.
Bad part it was the inverter board that blow on my fridge costing me $140 for part and 1/2 a day of studying the system.
New fridges run on R134a refrigerant btw. The same stuff you find in your modern car.
