    • 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

    • Great Option
Style: 28000 Watts - Gas Only - CO Sensor
5/5 Stars — Powerhouse Performance and Reliability! I recently purchased the Westinghouse WGen20000c generator, and it has completely exceeded my expectations. This thing is an absolute beast when it comes to power output — easily handling my entire home’s electrical load during outages, including large appliances, HVAC, and even workshop equipment, all without a hiccup. The starting and running watts (28,000/20,000) give a lot of peace of mind, especially during storm season. The electric start makes it incredibly easy to fire up, and the remote start option is a great convenience feature that saves me from having to step outside in bad weather. I’m also impressed with how well-built and thoughtfully designed it is. The heavy-duty frame, solid wheels, and sturdy handle make it surprisingly manageable for its size. The digital display is clear and easy to read, providing all the key performance information I need at a glance. Noise levels are lower than I expected for a generator of this size, and the fuel efficiency is excellent — it runs for hours on a single tank, even under substantial load. Maintenance is straightforward thanks to the well-laid-out design and clear instructions in the manual. In short, the WGen20000c delivers professional-grade performance at a residential-friendly price. Whether you’re preparing for emergencies, powering a large job site, or just want the ultimate backup solution, this generator is worth every penny. Highly recommend Westinghouse for anyone serious about reliable, high-capacity power. ... show more

    • It’s a huge BEAST! Plenty of power for entire house.
Style: 28000 Watts - Gas Only
What a huge BEAST!! I been running 7550 watts Generac generator past few years, only issues I faced was not able run AC, Dryer what runs 220 volts. We able to cook on stove with only 2 burners. My Golly, this beast is something! Being heavy equipment mechanic, this thing not as loud as my 7550 Generac. I was able do ANYTHING in my home even 5 tons AC. The positive thing it contains breakers on each plugs., lots of plugs to run cords to my shop nearby. Moving it not bad with the solid wheels, weights 680 lbs. loaded with gas and oil. I added rack on top hold my cords and such. Starting this thing really different. Like a robot self start once button was pushed. I put synthetic oil in it instead using factory as I live in cold climate and stat any temperature. This thing runs GREAT!! I put it together was a breeze as I didn’t read the instructions, I just knew what I’m doing. I was lucky enough to own a cherry picker to get it off the pallet. I know some customers not prepare for that. Lol. I was, knew gonna be heavy. Love the frame around it. Xcel energy was so pissed I was prepared to have power when they don’t want me not having power. We people should always be prepared. I’m happy to have this BEAST!! 20k running watts is just more than I need. Those who curious, my house 3,300 square foot. ... show more

    • Great Generator & Much Less Expensive than More Advertised Brand
Style: 28000 Watts - Gas Only
We ordered the WGen20000 4 months ago and, luckily, have not had to use it to power the house yet. It arrived on time without any issues even though it is a big, heavy item (600 lbs). With the help of a certified electrician, we were able to set it up ready for the next hurricane. It is loud, but it easy to start and should be able to deliver power to our entire house. The only reason I gave 4/5 stars is that the low power mode does not work. I will call the customer support number to see how to correct this issue. It is less than half price of the most popular brand and does everything that the other is advertised to do. ... show more

    • Westinghouse Generator Should Do The Job
Style: 28000 Watts - Gas Only - CO Sensor
The Westinghouse 20,000 watt generator was shipped promptly and received it in 3 days. Very easy to set up—add oil which was furnished, fill gasoline tank, set controls, charge the battery which was included, and start it up. Although weighing in excess of 600 pounds, with the attached handles and large wheels it was very easy to maneuver to the desired location. The handles are adjustable to two different heights for people tall or short. Starting was immediate after charging the battery. Using the remote control, I was able to start the generator from inside my home at about 60 feet with only one touch of the start button. It just as easily was shut down by the same remote. Have not wired it into my home electric circuit yet. I need an adapter to connect the 50amp outlet to my transfer switch. I am sure the 20,000 watt output will handle all the electric appliances and lights I will need on when a power outage occurs. Noise level from the twin cylinder 999cc gasoline engine is moderate. Since I have located the generator in my attached garage, the noise level of the engine won't be a problem. Upon start up, the digital gauge showed 241 volts being generated. The large 17 gallon gas tank is a plus for a long power outage which might last more than a day. Very pleased with the purchase. ... show more
