    • Great Power & Great Price
Style: 28000 Watts - Gas Only - CO Sensor
Impressive unit. Just received and all works well. Assembly was a no brainer. Extremely easy to start including with the remote start. Quieter than expected although still loud enough to scare the animals. Needed the added starting and running power. Beware, this is a heavy unit. Unpacking takes two to four people to get it off the pallet (unless you happen to have an engine lift installed). Great buy at this point. ... 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

    • Horrible Customer Service and Product
Style: 28000 Watts - Gas Only
In May 22 of 2023 I went online and bought a Westinghouse generator and had tons of problems to get it to stay running. I tried to get help from Westinghouse with no luck. Then I went on line and checked for trouble shooting problems for the generator and found that they have problems with the fuel line and tanks. I did find a block inside and the lines were falling apart. I replaced them and cleaned the tank and that fixed the problem at the time. Now one week ago today on Monday it stopped working again. We’ve been trying to get help from them again with no luck. Every time we talk to them, they give us a different excuse. My warranty says labor and parts and they are telling us that the parts that I need and labor are not covered under the 3 year warranty. My food truck has been down for a week and losing money. I would never recommend anyone to buy a Westinghouse product and have to go through all the problems that we have had to go through. I used to think Westinghouse was a good name, but it sure isn’t anymore! The repair centers that used to work with them, don’t anymore because they are too hard to work with. ... show more

    • Awesome Product (5 STARS)
Style: 28000 Watts - Tri Fuel - CO Sensor
Just plain awesome. Just a couple of days in... This thing is large and heavy and you will need help getting it off of the pallet it is delivered on (an overhead crane or engine lift would be VERY helpful) It will for sure take care of whole house power when needed. It is a bit loud but for myself I do not care, it will take care of power requirements in an emergency. I cannot speak about fuel efficiency yet as it is too new, but If gasoline (17-gallon tank) is used as a backup for propane or natural gas (I prefer these over gasoline so carbon is not built up in the cylinders) I believe it should operate great for many hours. It was very easy to put together having only to install the wheels, lift bar and hook up the negative post of the battery. After assembly, I hooked up my propane bottle and opened the valve, set the fuel source to propane, turned on the battery, pressed the remote start button and it started right up. I look forward to having this generator set up as a permanent fixture to power our home when needed. We lose power around here too often. ... show more
