The verdict

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.
