Westinghouse iGen4500
Best-selling RV inverter, remote start · Reviewed by Drew · amazon.com live, Sept 28 2026
Why it scored a 86
At $849, the Westinghouse iGen4500 is the best-selling RV inverter on Amazon, with 5,500-plus ratings at 4.6 stars pushing Reliability and Satisfaction both to 92. Features reach 84 on remote key-fob start, a 52 dBA rating, up to 18 hours in Economy mode, and an LED data center. Warranty lands at 78 for 3-year coverage. The caveat is weight at 98 pounds, and the listing title now reads 5,000 peak watts for the iGen5000 refresh, so confirm the model at checkout. It is for RV owners and home-backup buyers who want quiet power with push-button convenience.

Should you buy the Westinghouse iGen4500?
Buy the Westinghouse iGen4500 if you want quiet inverter power with push-button convenience for an RV or basic home backup. It is the best-selling RV inverter on Amazon for a reason: 3,700 rated watts, a TT-30R outlet that plugs straight into a 30 A camper, 52 dBA, and up to 18 hours on 3.4 gallons in Economy mode. At $849 it is $134 more than the Champion 4000W Dual Fuel and gives up propane in exchange for remote start, a bigger tank and quieter running.
Where it earns its score
- Quiet and long-running. 52 dBA and up to 18 hours per tank in Economy mode is campground-friendly all night.
- Remote key-fob start. Electric, push-button and recoil as well. Start it from inside the RV.
- Reliability and satisfaction both score 92. A huge owner base and few complaints beyond weight.
- Clean power. Under 3% THD, safe for laptops and RV electronics without a filter.
What to know first
- Gasoline only. No propane option. The Champion 4000W Dual Fuel runs both for less money.
- 98 lb. Telescoping handle and wheels help, but lifting it into a truck bed is not a solo job.
- Model confusion. Westinghouse sells a refreshed iGen5000 variant; check the listing shows iGen4500.
- Warranty is the lowest ViperScore factor. Three years limited scores 78 against Champion's 100.
Our verdict
The Westinghouse iGen4500 scores 86, a Strong Buy and second in Portable Generators. Choose it over the Champion 4000W Dual Fuel if remote start, run time and low noise matter more than propane. Choose the Champion at $715 if you want fuel flexibility and the stronger warranty.
