    Portable Generator

    Super happy with purchase….so far, easy to set-up and very user-friendly. This will power my entire house in the vent of a power outage. Not afraid of storms anymore….

    So far so good it works

    We started it and it works we haven’t hooked it up to the house so we will update the review once that happens.

    I got the power…

    I know a picture of a brand new generator with mud on the tires isn’t very pleasing to look at. I chose this picture to tell you that even at 540lbs. This unit is very manageable. The weight is distributed evenly and the tires make traversing a muddy yard easier. The sound rating is incredible as it only puts out about 74dba measured. The big VTWIN 999cc Westinghouse doesn’t even bat an eye when’s load is placed on. My house is a 2,400 sq ft. home and everything is electric. Not a problem powering it up and maintaining the comforts of home during a outage. The customer service you receive from Westinghouse is unlike I’ve ever experienced. They are very helpful. They don’t treat you as another sale but as a lifelong customer they do care about your satisfaction. This is the largest generator you can purchase in the portable class. Don’t wait until you wish you had it, order today.

    Great Investment

    This generator is well built and is big enough to handle just about any situation you throw at it. We bought this for our home emergencies as we live in an area with frequent storms and a hurricane season.

    Absolute Beast

    First things first the Wgen20000 is an absolute beast and I am so happy I bought this generator.This 28kw starting 20kw running generator is massive but surprisingly it’s super easy to move around with the included wheel kit so don’t be intimidated by the weight or size.The generator is loud but it’s to be expected but the smart idle is where you find the sweet spot not just in performance but how it separates itself from other generators . I say this most will vary Wildly with different loads but this beast just runs steady and you can hardly tell any difference with different loads

    Runs smooth, enough power to run our house

    Easy push start. Simple and concise instructions. Runs quiet on low idle. Easy to move around with wheels and handle.
