It depends on the AC unit’s starting and running watts. Many 13,500 BTU ACs require more than 2,000 starting watts.

What’s the quietest generator for RV AC use?
The Honda EU2200i and Westinghouse iGen4500 are among the quietest, with noise levels as low as 48–52 dB.

Do I need an inverter generator for my RV AC?
Inverter generators provide cleaner power and quieter operation, making them ideal for RV electronics and AC units.

Can I run other appliances with the AC on?
Yes, but make sure your generator’s total wattage covers all appliances’ startup and running power.

What’s better: dual fuel or single fuel generators?
Dual fuel generators offer flexibility and longer runtime options, but single fuel models are often simpler and more cost-effective.

How to Match Generator Size to Your RV AC
