  • Outstanding Power and Convenience
Style: 28000 Watts - Gas Only - CO Sensor
November 2025 I purchased the Westinghouse 28kW Generator with Remote Start, and I couldn’t be happier with my decision. This generator is an absolute powerhouse. It easily runs my entire home—including central air conditioning, appliances, and electronics—without even breaking a sweat. The remote start feature is a game changer. Being able to start the generator from inside the house during bad weather is incredibly convenient and adds a layer of comfort and safety. It fires up quickly and runs smoothly every time. Installation was straightforward, and the build quality is excellent. It feels durable, solid, and well-engineered. The noise level is surprisingly reasonable for a generator of this size, and the performance has been consistent and reliable during outages. If you’re looking for dependable whole-home backup power with modern convenience features, this generator is a fantastic investment. I highly recommend it to anyone who wants peace of mind during storms or unexpected power outages. ... show more

  • Works well - major power and great value - smooth starting
Style: 28000 Watts - Gas Only - CO Sensor
The product worked right away and was quickly cranking out 18000 watts for our house. I really like the electric start and the battery was full when it arrived as well. I installed to 50A inlets and connected them to the 50A outlets through a Generator cord. Works great--just make sure you get a good cord (NEMA, etc.) The unit, like most other large generators is loud, but we've been able to find a good spot for it where a some fencing blocks most of the noise from the main house. Beyond that, it IS very heavy. I can wheel it around on level ground in the grass but not up any sort of hill. I eventually used a very small winch to get it up a hill where we needed it to go. I was able to unbox it and set-it up without an other help. The best thing I like about this is the value. It lets me do whole house power, reliably, with dual fuel for less than $4000. As long as you're willing to do a little work for yourself in set-up, I think it's a great deal versus an installed whole home generator. I also like the flexibility of the dual fuel. I am planning on using propane as much as possible, but it's nice to know that I can switch to gas in an extended outage, assuming I can drive out to the gas station and/or keep enough gas around. Overall very satisfied. ... show more

  • Great generator.
Style: 28000 Watts - Gas Only - CO Sensor
Big bad ass generator This thing is big but I handled moving it with the wheels with no issue. Keep it where my older generac was under a roof and out of the weather. Where I live, you have to have a generator. I love the key remote start. I just kill the main on the pole start it up hit the indeed breaker and I'm not in the dark anymore. Great purchase. ... show more

  • Great backup generator
Style: 28000 Watts - Gas Only - CO Sensor

  • Thinking about a Generac? Consider this.
Style: 28000 Watts - Gas Only - CO Sensor
Got this to power home for future storms and hurricanes. Just as powerful as a generac but only a 1/3 of what generac cost. I had electrician install 2 50 amp inlet boxes, interlock kit and a 100 amp breaker. With two 50 amp cables to the inlet boxes this powers a 3200 sq foot home with a 6 ton ac/ heat pump, 600 foot well, two refrigerators, every appliance and fixture in our home. We did a four hour test run after set up and this generator performed flawlessly. It's heavy but easy to roll around. The alternator cover was damaged during shipping but I bent it back in shape and ordered a new one for $12.99 from Westinghouse. Amazon took 10% off the total price for my trouble. Was skeptical that it would power the whole home, not anymore. Zero buyers remorse on this purchase...I have also purchased a portable 48 gallon fuel tank and pump that our small tractor can lift on and off pickup truck. I'll fill it up when hurricane season starts and use the tank to fuel generator mowers boat cars etc etc...we went without power for 8 days after Helene. We had a 7000 watt generator but we're not happy with all the cord dragging 5 gallon cans of fuel every 8 hours...this is a much better set up, the electrician was very impressed by the quality of the generator as well. I also like the idea that its not permanently attached like a generac with a big propane tank. I can take it other places or let a friend borrow it... ... show more

  • save your money buy a Honda or a Generac
Style: 28000 Watts - Gas Only - CO Sensor
$3000 for junk. Doesn't have the power it says it does. Reality it's probably 12k worth of power. Had it less than a month and I use it for a food truck. Can't run half the truck because it pops the breaker on the generator. Fine I can make it work. Now it run for 10 min and just turns off with and with out a load. It's well ventilated and I put a fan on it so it can't be the CO2 sensor and it's not overheating. Don't waste your money go with a Honda or a Generac generator. Completely disappointed because it all started happening after the 30 day return policy. So now I have a $3000 piece of junk sitting in my shop. ... show more
