Air Conditioners typically use more power than any other RV appliance which makes the AC unit(s) a good place to start when selecting a new RV generator for a motorhome, trailer, or fifth-wheel.
The motors in air conditioners use more power to start than they do while running. The motor requires the starting watts for a few seconds as the power draw quickly tapers off to the running watts.
7,000 BTU RV air conditioner 1700 starting watts, 600 running watts 10,000 BTU RV air conditioner 2000 starting watts, 700 running watts 13,500 BTU RV air conditioner 2750 starting watts, 1250 running watts 15,000 BTU RV air conditioner 3500, starting watts, 1500 running watts
These are typical power requirements. Different model air conditioners use more or less power even though they carry the same BTU rating. Check the specifications for your specific AC model for the correct starting and running watts.
