Our editorial team weighed WEN's published specifications and how it stacks up against similar products in the generators category. What stands out: Versatile RV/Transfer-Switch Outlets, Long Runtime, and Wheels & Handles. Where it falls short: Needs Gasoline Storage and Noisier Than Inverter Models. That puts it at 8.2/10 on our WG Score – an excellent, well-rounded option.
Reviewed byEthanWhen choosing a generator for your RV air conditioner, the single most important specification is its running (continuous) wattage. This determines whether the generator can sustain the AC unit’s compressor and fan without tripping or stalling. A generator that cannot deliver enough continuous power will leave you sweating in the heat, regardless of brand or price. That is why we focus on running watts above all else in our picks.
For more on powering your RV, check out our guide to Best Portable Generators for RV Camping.
Running Watts Explained
Running watts (also called rated watts) is the amount of power a generator can produce continuously. RV air conditioners typically require 1,300 to 2,000 running watts to operate, plus a surge of 2,000 to 4,000 starting watts when the compressor kicks on. If your generator’s running wattage is too low, the AC may not start or may shut off after a few minutes.
To put this into perspective, consider the PowerSmart 3800 Watt Dual Fuel Inverter Generator. It delivers 3,300 running watts on gasoline and 3,100 on propane. This means it can easily handle a typical 13,500 BTU RV air conditioner (which draws about 1,500 running watts) while still having 1,800 watts left over for lights, a refrigerator, and charging devices. The calculation: 3,300 running watts minus 1,500 watts for the AC leaves 1,800 watts for other loads. That is plenty for a small microwave (1,000 watts) and a few LED lights (50 watts).

Fuel Type and Runtime
Dual-fuel generators (gasoline and propane) offer flexibility, especially in areas where propane is easier to store. Check runtime at half load; a larger tank means fewer refueling stops during long trips. For more on fuel options, see our Best 50 Amp RV Generators guide.
Noise Level
Inverter generators are typically quieter than conventional models. Look for models with noise ratings around 60-70 dB for campground-friendly operation. The PowerSmart operates at 70 dB, while the Generac iQ3500 is even quieter.
Portability and Outlets
Weight and wheel kits matter if you move the generator frequently. Ensure the panel includes an RV-ready 30-amp TT-30R outlet. The WEN models come with wheel kits and multiple outlets, including a transfer-switch-ready L5-30R.
