Running vs Starting Watts
Starting watts (surge) handle the initial power spike from motors in refrigerators, air conditioners, and pumps. Running watts sustain continuous operation. For example, the Westinghouse iGen5000DFc provides 5000 starting watts and 3900 running watts, allowing it to start a 1/2 HP well pump (roughly 1000 starting watts) while still having reserve for lights and a TV. Always choose a generator with at least 20% overhead above your total running wattage to avoid overloads. If you need a unit that prioritizes clean power for electronics, check out The 5 Best Inverter Generators Dual Fuel of 2026.
Fuel Efficiency and Run Time
Fuel efficiency varies by load and tank size. The Westinghouse iGen4000DFc runs up to 7 hours on a 1.69-gallon tank at 25% load, which translates to roughly 4.1 hours per gallon. That’s excellent for a portable inverter generator, letting you power a small refrigerator and lights for an evening on just a couple of gallons. Larger units like the WEN DF8000X offer longer absolute runtime (10.5 hours at half load) but consume fuel faster per hour. Consider your typical usage duration and fuel availability when choosing.
Noise Levels
Inverter generators like the Westinghouse models operate as low as 52 dBA, which is quieter than a normal conversation. Conventional generators often exceed 70 dBA. For camping, RVing, or neighborhoods with noise restrictions, an inverter model is strongly recommended. The WEN DF8000X, being a conventional generator, will be noticeably louder.
Portability and Outlets
All four models include wheel kits and handles, but the Westinghouse inverter generators feature telescoping handles for easier pulling. The WEN DF8000X offers a 240V L14-30R outlet for transfer switch connectivity, while the inverters provide 120V only (TT-30R for RVs, plus standard 20A outlets). If you plan to connect to a home transfer switch, ensure the generator has a compatible outlet. For RV use, a TT-30R outlet is essential.

Frequently Asked Questions
Can I use a dual fuel generator indoors?
No. Even with CO sensors, all generators produce carbon monoxide and must be operated outdoors at least 20 feet from windows, doors, and vents. The CO shutdown feature is a safety backup, not a license for indoor use.
How do I switch between gasoline and propane?
Most dual fuel generators have a simple selector valve or require you to connect a propane hose to the regulator. Always turn off the generator before switching fuels. Propane provides longer shelf life and cleaner combustion, but slightly lower power output.
What size generator do I need for my RV?
For a 30-amp RV, a generator with at least 3600 running watts is recommended. The Westinghouse iGen5000DFc (3900 running watts) is a popular choice. For 50-amp RVs, you may need a larger unit with 240V output. Check our The 5 Best Rv Generators 30 Amp Dual Fuel of 2026 for more details.
How long do dual fuel generators last?
With proper maintenance (oil changes, spark plug replacement, fuel stabilizer), a quality inverter generator can last 2000-3000 hours. Conventional generators may have longer engine life but require more frequent maintenance.
