Reviewed byEthanWhen shopping for a best propane standby generators, the one spec that truly determines whether your purchase works out is running wattage. Peak watts get the headlines, but running watts tell you what the generator can sustain hour after hour. A propane standby generator that can’t handle your essential loads is just an expensive paperweight. That’s why we focus on rated output more than brand names or price tags.
In this guide, we break down 3 top-rated models from Westinghouse, Westinghouse Outdoor Power Equipment and show you exactly how their running watts translate to real-world power. For more on choosing the right generator, check out our best standby propane generators guide.
Running Wattage Explained
Running wattage (also called rated wattage) is the continuous power a generator can deliver without overheating or tripping breakers. It’s the number that matters most for powering your RV air conditioner, refrigerator, sump pump, or lights hour after hour. Peak wattage is a short burst for starting motors; running wattage is what keeps everything humming.
Let’s make this concrete with a real calculation. The Westinghouse iGen5000DF has a running wattage of 3900 watts on gasoline. A typical RV air conditioner draws around 1500 running watts, a refrigerator 600 watts, and a few lights and a TV add another 300 watts. That totals 2400 watts, leaving you 1500 watts of headroom for starting surges. In practical terms, this generator can comfortably power a 30-amp RV plus a few household essentials simultaneously. That’s the kind of real-world math that makes running wattage your most important spec.

Best Propane Standby Generators: Our Picks Against the Numbers
Best for Maximum Output: Westinghouse iGen5000DF 5000 Peak Watt Dual Fuel Inverter Generator – Super Quiet RV Ready Remote Start
With a running wattage of 3900 watts (gasoline) and 3900 watts on propane, this model tops the list for sheer capacity. It’s the pick if you need to run a large RV air conditioner plus a refrigerator and some lights without worry. The 18-hour run time on a 3.4-gallon tank means fewer refueling stops during long trips.
Skip this if: you don’t need the extra power and want a smaller, lighter unit for occasional camping. The iGen5000DF is a bit heavier than its 4000-watt sibling.
View on Amazon.comBest Balance of Power and Portability: Westinghouse iGen4000DFc 4000 Peak Watt Dual Fuel Inverter Generator – Super Quiet RV Ready Remote Start CO Sensor
This model delivers 3300 running watts on both fuels, which is enough for most RV essentials and home backup needs. It’s lighter and more compact than the 5000-watt models, making it easier to move and store. The built-in CO sensor adds peace of mind for safe operation.
Skip this if: you need to power a large RV or multiple high-draw appliances simultaneously. The 3300 running watts may not be enough for a 50-amp RV plus extra loads.
View on Amazon.comBest Value with CO Protection: Westinghouse iGen5000DFc 5000W Peak Dual Fuel Inverter Generator – Super Quiet RV Ready Remote Start CO Sensor
This model matches the iGen5000DF’s running wattage of 3900 watts but adds a carbon monoxide sensor for automatic shutdown. It’s the same powerful output with an extra safety feature. The 18-hour run time on a 3.4-gallon tank is identical to the non-CO version.
Skip this if: you already have a CO detector in your RV or home and don’t need the built-in sensor. The iGen5000DF without CO sensor is slightly more budget-friendly.

Frequently Asked Questions
Can these generators run on propane?
Yes, all three models are dual fuel and can run on either gasoline or propane. Propane is cleaner burning and stores longer, but it provides slightly less power output than gasoline. Check the specs for exact propane running watts.
Do I need a CO sensor on my generator?
Carbon monoxide sensors are a valuable safety feature, especially if you plan to use the generator near your RV or home. The iGen4000DFc and iGen5000DFc include built-in CO sensors that automatically shut down the generator if CO levels become dangerous. For more safety tips, see our best quiet gas generators guide.
How many watts do I need for an RV?
A typical 30-amp RV needs about 3600 peak watts and 3000 running watts for the air conditioner, refrigerator, and lights. The iGen5000DF and iGen5000DFc with 3900 running watts are well suited for this. The iGen4000DFc with 3300 running watts can handle a smaller RV or a 30-amp setup with careful load management.
What is the warranty on these generators?
All three Westinghouse generators come with a 3-year limited service, labor, and parts coverage. This is a solid warranty for portable generators in this class.
