Understanding Power Output: Peak vs. Rated Watts
Peak watts (or starting watts) handle the surge when a motor starts, like a refrigerator compressor or air conditioner. Rated watts (running watts) sustain continuous operation. For example, the Westinghouse iGen5000DFc provides 5000 peak and 3900 rated watts. A typical RV air conditioner may draw around 1500 running watts but spike to 2500 on startup, so a 3900 rated watt unit has plenty of headroom. To estimate your needs, add up the running watts of everything you plan to power simultaneously, then add the highest single starting surge.
Fuel Type: Propane vs. Gasoline
Propane burns cleaner, causes less engine wear, and can be stored indefinitely without degradation. Gasoline offers higher energy density and is more widely available, but degrades over time and requires stabilizers. Dual fuel generators like these three Westinghouse models let you choose based on availability and preference. For a 3 day outage running a 1500 watt load continuously, a 3.4 gallon gas tank at full load provides roughly 18 hours of runtime; on propane, a standard 20 lb tank (about 4.7 gallons propane equivalent) would give similar or slightly less runtime depending on efficiency.
Noise Level and Inverter Technology
Inverter generators produce cleaner power (less than 3% THD) suitable for sensitive electronics like laptops and CPAP machines. They also run quieter and more fuel efficiently than conventional generators. All three Westinghouse models operate as low as 52 dBA, about the volume of a normal conversation, making them ideal for campgrounds and neighborhoods with noise restrictions. Economy mode further reduces fuel consumption and noise by adjusting the engine speed to match the load.
Portability and Outlets
Look for features like telescoping handles, flat free wheels, and a compact footprint. All three generators include a TT 30R RV ready outlet, two 20A household outlets, and USB ports. The LED data center displays fuel level, power output, remaining runtime, and voltage, so you can monitor performance at a glance.

Frequently Asked Questions
Can I run a portable propane generator indoors?
No. Even though propane burns cleaner than gasoline, portable generators still produce carbon monoxide (CO). Always operate them outdoors at least 20 feet from windows, doors, and vents. Models with built in CO sensors, like the Westinghouse iGen4000DFc and iGen5000DFc, provide an extra layer of safety by automatically shutting down if CO levels become dangerous.
How long does a 20 lb propane tank last on a generator?
Runtime depends on the load. At 50% load (around 2000 watts), a 20 lb propane tank can last approximately 10 to 15 hours on a 5000 watt class dual fuel inverter generator. At full load (3900 watts), runtime drops to roughly 6 to 8 hours. The Westinghouse iGen5000DFc can run up to 18 hours on a full gas tank at 25% load, but propane runtime will be similar or slightly less due to lower energy density.
Are dual fuel generators more expensive to maintain?
Not necessarily. Propane burns cleaner than gasoline, which can reduce carbon buildup and extend engine life. However, you may need to clean the carburetor and fuel system if you switch between fuels frequently. Regular oil changes and air filter maintenance are the same as with any generator. For more maintenance tips, check our Reviews category for related guides.
Can I parallel two Westinghouse inverter generators?
Yes, all three models in this roundup are parallel capable, meaning you can connect two identical units with a parallel kit to double your available power. This is useful for running larger appliances or for backup when you need more than 5000 peak watts. Always use the manufacturer recommended parallel kit for safe operation.
What size generator do I need for my RV?
For most RVs, a 3000 to 4000 watt generator is sufficient to run a 13,500 BTU air conditioner, refrigerator, lights, and a few small appliances. If you have a 15,000 BTU AC or want to run multiple high draw devices simultaneously, consider a 5000 watt model like the Westinghouse iGen5000DFc. Always check the startup surge of your AC unit and add 20% headroom for safety.
