Best Rv Ready Inverter Generators: How the Top Picks Compare
Which generator offers the most power for RV use?
The PowerSmart 3800 Watt Dual Fuel Inverter Generator leads in raw output with 3,800 surge watts on gasoline and 3,300 rated watts. That is enough to run a 13,500 BTU RV air conditioner plus lights and a refrigerator simultaneously. The Westinghouse iGen2800 provides 2,800 peak watts and 2,200 rated watts, which is better suited for smaller RVs or running essentials like a microwave and TV. For maximum RV power, the PowerSmart is the clear winner.
How do they compare on noise and portability?
The Westinghouse iGen2800 is the quietest of the top contenders at 52 dBA, which is quieter than a normal conversation. It also weighs only 46.3 pounds, making it easy to move. The PowerSmart is rated at 70 dB at 23 feet and weighs 50.7 pounds, still portable but slightly louder. If low noise is your priority, the Westinghouse wins this dimension.
Which model offers better fuel efficiency and runtime?
The Westinghouse iGen2800 runs up to 12 hours on a 0.98-gallon tank at 25% load, thanks to its Economy Mode. The PowerSmart does not list a specific runtime, but its larger 149cc engine and dual-fuel capability give it flexibility. For long camping trips without refueling, the Westinghouse is more efficient. For more on fuel options, see our fuel types category.
How do they handle sensitive electronics?
Both generators produce clean power with less than 3% total harmonic distortion (THD), making them safe for laptops, phones, and other sensitive devices. The PowerSmart also includes a CO shutdown sensor for added safety. The Westinghouse has a digital display showing fuel level and power output. Both are excellent for electronics, but the PowerSmart’s CO sensor adds peace of mind.

Understanding power requirements for your RV
To determine what size generator you need, add up the running watts of your RV’s appliances. A typical RV air conditioner uses around 1,500 running watts, a microwave 1,000 watts, and a refrigerator 600 watts. The PowerSmart 3800 can handle all three at once, while the Westinghouse iGen2800 is better for smaller loads. For example, if you run a 1,500-watt AC and a 600-watt fridge (2,100 watts total), the Westinghouse’s 2,200 rated watts is just enough, leaving little room for extras.
Fuel type and runtime considerations
Dual-fuel generators like the PowerSmart let you switch between gasoline and propane, which can be useful during fuel shortages. Propane also burns cleaner and stores longer. However, propane provides slightly less power: the PowerSmart produces 3,500 surge watts on propane versus 3,800 on gasoline. For extended trips, consider the Westinghouse’s 12-hour runtime on a single tank.
Portability and storage
Weight and size matter if you need to move the generator frequently. The Westinghouse iGen2800 weighs 46.3 pounds and has a compact suitcase design. The PowerSmart is 50.7 pounds but includes wheels and a handle for easier transport. The WEN GN400iM is an open-frame design that weighs less than a standard 4,000-watt generator, but it is larger than closed-frame models.

Frequently Asked Questions
Can I run my RV air conditioner with a 2,800-watt inverter generator?
It depends on the AC unit’s starting watts. A 13,500 BTU RV AC typically requires about 2,800 starting watts and 1,500 running watts. The Westinghouse iGen2800 provides 2,800 peak watts, so it may struggle if other appliances are running. The PowerSmart 3800 is a safer choice for larger ACs.
What is the difference between open frame and closed frame inverter generators?
Open frame generators like the WEN GN400iM are lighter and more affordable but louder. Closed frame models like the PowerSmart and Westinghouse are quieter and more compact, making them better for camping. For more on portable options, see our best portable inverter generators for camping guide.
Are inverter generators safe for sensitive electronics?
Yes, inverter generators produce clean power with less than 3% THD, which is safe for laptops, phones, and TVs. All models in this comparison have pure sine wave output.
How do I parallel two inverter generators?
Generators with parallel capability, like the Westinghouse iGen2800 and WEN GN400iM, can be connected using a parallel kit. This doubles your available power. For example, two Westinghouse iGen2800 units can provide up to 5,600 peak watts.
