Power Output: Starting vs. Running Watts
For RV use, the key spec is running (rated) watts, which determines continuous load capacity. Starting watts cover surge requirements for appliances like air conditioners. For example, a 13,500 BTU RV AC typically needs about 1500-2000 running watts but may surge to 2500-3000 starting watts. The Westinghouse iGen5000DFc offers 3900 running watts, which can handle a single AC plus lights and a refrigerator, while the PowerSmart 3800W provides 3300 running watts on gasoline, sufficient for smaller RVs or moderate loads.
Fuel Type and Run Time
Dual fuel generators (gasoline and propane) offer flexibility, especially for extended trips where propane is easier to store. The Westinghouse iGen5000DFc runs up to 18 hours on a 3.4-gallon gas tank at 25% load, while the WEN GN5602X provides up to 12.5 hours at half load on 4.3 gallons. Propane typically yields slightly lower wattage but longer shelf life and cleaner burning. For RVers who prioritize run time, the Westinghouse is a strong choice.
Noise Level and Inverter Technology
Inverter generators produce clean power (less than 3% THD) safe for sensitive electronics and are generally quieter than conventional models. The Generac iQ3500 boasts a 40% noise reduction, while the Westinghouse iGen5000DFc operates at 52 dBA, comparable to a quiet conversation. The PowerSmart 3800W runs at 70 dBA, similar to normal conversation. For campgrounds with strict noise limits, an inverter generator under 60 dBA is ideal.
Portability and RV Readiness
Weight and included outlets matter for RV use. The PowerSmart 3800W weighs 50.7 lbs, making it one of the lightest in this class, while the WEN GN400iM is 30% lighter than standard 4000W generators. All models here include a TT-30R RV-ready outlet. The Westinghouse iGen5000DFc features a telescoping handle for easier maneuvering. For those who need to move the generator frequently, lighter models like the PowerSmart or WEN GN400iM are preferable.

Frequently Asked Questions
Can a 4000 watt generator run an RV air conditioner?
Yes, most 4000 watt generators can run a single 13,500 BTU RV air conditioner, along with lights, a refrigerator, and small appliances. However, you must consider the starting surge; a generator with at least 3500 running watts is recommended for reliable operation. For larger AC units or multiple appliances, consider models with higher running watts like the Westinghouse iGen5000DFc.
What is the difference between inverter and conventional generators for RV?
Inverter generators produce cleaner power (less than 3% THD) that is safe for sensitive electronics like laptops and smartphones. They are also quieter and more fuel efficient, especially at partial loads. Conventional generators are typically heavier, louder, and produce power with higher THD, which can damage sensitive devices. For RV use, an inverter generator is the preferred choice.
How long can a 4000 watt generator run on a tank of gas?
Run time varies by model and load. For example, the WEN GN5602X runs up to 12.5 hours at half load on its 4.3-gallon tank, while the Westinghouse iGen5000DFc can run up to 18 hours at 25% load on 3.4 gallons. Running at higher loads reduces run time. Always check the manufacturer’s specifications for your specific model.
Do I need a dual fuel generator for RV?
Not necessarily, but dual fuel offers flexibility. Propane is easier to store long term and burns cleaner, while gasoline is more widely available and provides slightly higher wattage. If you plan to boondock or want backup fuel options, a dual fuel model like the Westinghouse iGen5000DFc or PowerSmart 3800W is a good investment.
