How to Choose Generators for RV ACs

Power Requirements

Your RV air conditioner’s starting watts determine the minimum generator size you need. Most 13,500 BTU AC units require 2800-3000 starting watts, while 15,000 BTU units need 3300-3500 watts.

Always add 20% extra capacity for other appliances you’ll run simultaneously. A 4000-watt generator handles one AC unit plus lights and small devices, while 6000+ watts supports multiple ACs.

Fuel Type Options

Dual fuel generators offer the most flexibility by running on both gasoline and propane. Propane stores indefinitely without degrading, making it ideal for emergency backup and seasonal use.

Gasoline typically provides slightly higher wattage output but requires fuel stabilizer for storage. Consider your camping style and fuel availability when choosing between single or dual fuel models.

Noise Level

Quiet operation matters in campgrounds where noise restrictions often apply. Look for generators rated under 65 dBA from 23 feet for comfortable camping.

Inverter generators run quieter than conventional models and adjust engine speed based on load. ECO mode further reduces noise during light loads while improving fuel efficiency.

Portability and Weight

Generator weight directly impacts how easily you can load, unload, and position it at campsites. Models under 60 pounds work for most people, while anything over 100 pounds may require two people or a ramp.

Look for built-in wheels and telescoping handles on heavier units. Compact designs fit better in RV storage compartments and leave more space for other gear.

Safety Features

CO sensors that automatically shut down the generator when carbon monoxide reaches dangerous levels are essential for RV safety. Never run a generator inside an RV or in enclosed spaces.

Low-oil shutdown protects the engine from damage, while overload protection prevents electrical issues. Fuel shutoff features extend engine life by emptying the carburetor before storage.

Frequently Asked Questions

What size generator do I need to run my RV air conditioner?

Most 13,500 BTU RV air conditioners need a generator with at least 3000 starting watts and 1800 running watts. For 15,000 BTU units, choose a generator with 3500+ starting watts to handle the initial surge when the compressor kicks on.

Can I run two RV air conditioners on one generator?

Yes, but you need at least 6000-7000 starting watts to run two 13,500 BTU air conditioners simultaneously. The WEN DF680iX or DuroStar DS13000MX provide enough power for dual AC units plus other appliances.

Are dual fuel generators better for RVs?

Dual fuel generators offer more flexibility since propane stores indefinitely without degrading and is widely available at RV parks. You can switch to gasoline when propane isn’t available or when you need maximum power output.

How far away should I place my generator from my RV?

Place your generator at least 20 feet away from your RV with the exhaust pointing away from living areas. Never run a generator inside your RV, in the storage compartment, or under the RV where carbon monoxide can accumulate.

Do I need an inverter generator for my RV?

Inverter generators are recommended for RVs because they produce clean power safe for sensitive electronics and run much quieter than conventional generators. The stable power output won’t damage your TV, laptop, or phone chargers.

Final Thoughts

The WEN DF680iX offers the best overall value with 6800 watts, dual fuel capability, and comprehensive safety features for serious RVers. For budget-conscious buyers, the Oxseryn 4000W delivers solid performance at an unbeatable price.

Focus on matching generator wattage to your AC unit’s requirements, prioritize safety features like CO sensors, and consider dual fuel models for maximum flexibility. Weight and noise level matter significantly for the camping experience.

Choose based on your specific RV size, typical camping duration, and whether you need backup power for your home as well.
