3,900 W running, 5,000 W surge — sustains the fridge, freezer and the essentials tier and everything below it.
Best forRV owners and outage-prone households who want 4 kW, EFI and propane on wheels at well under Honda or Yamaha prices.
The big Westinghouse inverter and the only one in this price class with electronic fuel injection. It makes 3,900 running and 5,000 peak watts on gasoline, 3,500 and 4,500 on propane, and the 224cc engine and 3.2 gallon steel tank give 18 hours at a quarter load on gas. That is long enough for a night of fridge, furnace and lights on one fill. The wheels, the key-fob start and the way EFI starts cleanly in cold weather without a choke dance all get good reports. Weight and noise are the complaints. Westinghouse lists it at 111 lbs on the spec sheet and 105.8 in its marketing copy, and its own noise figures disagree, so the higher 61 dBA figure is the one to plan around. The 30A outlet is TT-30R, not a 240V port, so it feeds RVs but not a 240V transfer switch. At $1,399 it undercuts the Honda EU7000iS by a wide margin but is a 4 kW unit, not a 7.
