Great features

We bought this 12000-Watt Remote Tri Fuel Inverter Generator with CO Sensor after going through a 21 hour power outage on July 3. We’ve also had 3 other shorter outages in the past 3 years. This item was recommended to us and has multiple features that we like and need. We haven’t used it yet but have much peace of mind that when the next outage occurs we will be ready.

Very Reliable, Great Performance!

I bought this generator over a year ago in April 2025. I live in Virginia and I've used it several times during power outages. I hooked up this generator to our house electrical panel. I exclusively use propane fuel in order to avoid any carburetor issues. This generator has been fantastic, it's been very reliable and I've had zero issues. I conducted a fair amount of research before buying and I have a lot of confidence in Westinghouse as a result of this generator.

Awesome Generator

Awesome generator. We unboxed it put in oil in and it started on the first try. We are using propane. Overall the Generator is excellent very nice. Super easy to start and fairly quiet for its size. We ran our 30 amp motorhome with ease. Now we are 100% ready for the next power outage. We love the generator
