Looking for 12-volt RV air conditioners? We sell several models of 12-volt DC RV air conditioners, which use much less power than a typical 120-volt RV air conditioner. When you're looking to run an RV air conditioner off-grid without access to shore power or a generator, you'll want a 12-volt RV air conditioner for its electrical efficiency. Some Dometic RV air conditioner and Coleman RV air conditioner models run on 12VDC power, and we also have RV air conditioner options from Nomadic Cooling.
