Our take on the Westinghouse 4000 Peak Watt Super Quiet Portable Inverter Generator

The Westinghouse iGen4000c is a gasoline inverter generator rated at 3300 running watts and 4000 peak watts, with a TT-30R RV outlet, two household outlets and two USB ports. It runs as low as 52 dBA and up to 7 hours on a 1.69-gallon tank, and it starts by push button, electric start or the included key fob. A CO sensor shuts it down automatically, and a rotating LED display shows fuel level, output, remaining runtime and voltage. At $709 at eBay as of November 5, 2026, it sits at the low end of its recent range across the 8 stores listing it new.

What reviewers say

Buyers describe the iGen4000c as quiet and easy to start, with the remote fob and RV outlet getting the most mention. Complaints center on its weight and on the limited running wattage for bigger loads.

What people mention
  • NoisePraisedOwners say it runs quietly enough to hold a conversation next to it at camp.
  • StartPraisedThe key fob and push-button start are called easy and reliable.
  • WeightCriticisedAt 61.7 lb it takes two people or a ramp to load into a truck.
  • Power outputMixedIt handles essentials and small RVs, but 3300 running watts falls short for large air conditioners.
  • RuntimeMixedUp to 7 hours is fine for an evening, but the 1.69-gallon tank means refueling on longer trips.

Questions and answers

Is the iGen4000c quiet enough for campgrounds?
It is rated as low as 52 dBA, which is quieter than most open-frame generators. Many campgrounds still have quiet-hour rules, so check yours.
Can it run an RV air conditioner?
A small RV air conditioner can start on 3300 running watts, but a large unit plus other loads will trip the overload protection. Check your AC's starting watts first.
How does it start?
It has push-button electric start, recoil backup and a remote key fob included in the box.
Does it have a CO shutoff?
Yes. A carbon monoxide sensor shuts the engine down automatically if CO builds up around the unit.
Is $709 a good price?
That is the best new price among the 8 stores listing it as of November 5, 2026, and it sits at the low end of its recent range.
Can I run it on propane?
No. The iGen4000c is gasoline only, with a 1.69-gallon tank.
