The efficiency of a battery air con unit is a crucial factor to consider, especially for off-the-grid usage. The Nomadic Cooling Co. 12V unit is a good indication of being more suited for this type of usage.

A 12V unit might run less often than a more powerful Dometic unit, which could save energy and prolong battery life. However, the cost of a 12V unit is about 3x the price of a 120V unit, which raises questions about its value.

You can make a 120V A/C run from the battery bank, but you'll have limited autonomy, even with a large battery bank like 600Ah of Lithium batteries. This can cost over $6,000 in batteries alone, making it a significant investment.

Efficiency can be a complex topic, but let's break it down simply. The gap in performance between the Nomadic Cooling Co. and the Dometic is a good indicator of efficiency.

Being more powerful, the Dometic might run less often, which could be a plus in certain situations. However, this doesn't necessarily mean it's more efficient overall.

A 12V unit like the Nomadic Cooling Co. is often more suited for off-the-grid usage, as seen in its comparison to the Dometic. This is because it can perform well with a smaller power source.
