  • Big Generator.

Great product. Powerful. Runs great.

  • Replacement parts
Style: 28000 Watts - Tri Fuel - CO Sensor
This generator is a BEAST!! It is everything I expected from Westinghouse. It was a breeze to assemble, although getting it off the packing crate base took some doing by myself. Added the recommended amount of oil (included in package), connected a propane cylinder and it started right up. I found it a lot quieter than my old Workhouse 5000. My biggest issue was getting it registered, the manual is sorely lacking in this respect. Note: the proper oil filter (Wix 51394 or Fram PH4967) are available at your neighborhood parts store. The replacement air filter is only available from Westinghouse parts, (parts.wpowereq.com) - part number 2296. As of this post, I just ordered the last two filters! ... show more

  • Perfect midsize mobile generator
Style: 28000 Watts - Tri Fuel - CO Sensor
This generator is definitely a beast. I had a front loader so it was easy unpack and set up. I have a 7000 square-foot house. It will power two of my 4 ton air conditioners along with pretty much everything else in the house. Amazing. Definitely a must for some one that doesn’t want a fixed in place generator and the cost of one. ... show more

  • Bad A** generator!!
Style: 28000 Watts - Tri Fuel - CO Sensor
This thing is a monster!! I've got it running off natural gas, and it runs my whole house, in including my pool pump!! Definitely worth the money. All the parts for it are available and not expensive, but the parts are cheaper from Westinghouse. This generator also includes a battery maintainer

  • Beast
Style: 28000 Watts - Tri Fuel - CO Sensor
I received this today, (6 days early)!!! It didn't take long to put together and fire up. I did do it by myself and I'm 60 years old. It is very heavy but manageable. I connected to propane just for giggles because I plan to hook it up to natural gas. It fired up on the second start cycle. I'm now looking forward to the next power outage. ... show more

  • Beautiful Machine but it won’t run under load…horrible product support
Style: 28000 Watts - Tri Fuel - CO Sensor
EXTREMELY disappointed in this product and the support received. Received the generator on 7/23/26. Followed set up and break in instructions to the letter. The generator won’t run except for a minute or two under load…it just cuts off. Placed two calls to the support number, place a ticket, and responded to two emails. Each time I have to repeat what is happening. It’s like they haven’t even documented anything they’ve been told. I’ve asked for a replacement but nothing but crickets. Right now I have a 600 pound pice of scrap metal just in time for peak storm season. Not so much as a call from them. Horrible. ... show more

  • Westinghouse made it sound like plugging it in and have power.
Style: 28000 Watts - Tri Fuel - CO Sensor
To use the Westinghouse 28000 watts generator you have to hard wire it to get the max 20000. Westinghouse leaves that part out. You can’t run the generator on the 50 amp breaker and get the 200000 watts. Running it the 50 amp 12500 is the max.
