Super impressed

Was part of the "Bomb Cyclone" that hit the PNW on 11/19/24 and lost all power. After two days, we decided to invest in a generator knowing that this could happen again. The set-up was easy, the controls were well labeled, the starting process was explained with help from stickers located above the fuel line and choke lever (but make sure to read the manual first). The unit started with ease and ran for 4 days straight as we were out 6 days total. I was able to plug in the chest freezer, mini fridge, floor heater, lights, cable with TV, recliners, computer, and was also able to charge phones and flashlight batteries. This is my first generator ever and now wondering why we didn't purchase sooner. Would have made those first two days way more tolerabe! As a suggestion, even though the unit comes with a 20' heavy duty cord with 3-plug-in capabilities, I stronly suggest having a 50' or 100' equivalent heavy gauge (12g minimum suggested) to run from the unit into the house. If there was one thing I would try and change, it would be the noise output which I know accompanies all generators and just something you and the neighbors will have to deal with unless you devise something that dappens the noise without hindering the exhaust in any way. Overall, I'm super impressed and would recommend to family and friends without hesitation.

Save your money

What a waste of money. Worked great for the first month, now it won't stay running for more than 20 minutes at a time. Any time you put a load on it, it dies. This seems to be especially true if you have to use it on hot days. (Which when you're using it on an RV is when you need it the most).

Recommend the GP8000E to power a home

The GP8000E works well for running our whole house. We had an outage for 2 days and were able to run our whole house without any issues. We have a well water pump, AC, refrigerator, freezer, lights, etc. We did not encounter any issues. The portability works well for moving and storage.

Terrible warranty/parts service

I have had this machine for about two years. I am giving Generac one star because their customer service and warranty repair is very poor. I was not able to acquire a warranty part from the factory. My dealer was not able to acquire the warranty part from the factory. I could only find one repair shop that was willing to do warranty work for portable Generac, generators, and they took six months to repair my machine because Generac did not quickly supply them with the warranty part that they needed to repair my machine.

All good! Love the dual fuel. I do wonder if I can plumb the fuel from our home propane tank? or possibly use my 100# tank vs only a 20 or 30# ? It's perfect as a home backup, as is, just thinking of a fixed backup rather than having to run sep tanks & wire.

Excellent Generator

This is a great product for the price.The generator starts easily and runs fairly quiet.The fuel tank is huge and i can get about 8 hours out of a tank.I gave it 4 stars for only one reason and that is because of the wheels.This generator is very heavy and they should have sealed bearings on the wheels because when you have to move it on grass it is hard to push or pull.

Great Unit

I purchased about a month ago. Generator arrived in good condition, and unpacking and getting ready to use was well instructed, but a bit more time consuming than I had thought it would be. Only "semi-complaint" is the unit is very loud. It would get a five star from me if the muffler system made the unit a bit more quiet.

Bad Bad Bad

F...ing garbage. Do not buy. Runs rough if it starts. Worst generator I've ever had. I would say used but can't hardly use it. Bought new. Was garbage right out of the box. Should have returned. Spen up and get a Honda. This thing is junk

Poor Warranty Assistance

Purchased this portable generator, had a problem with it after 15 min. of running.. Called for assistance and No One would come to my house to repair it. They only would come if it was a standby generator. I like Generac Products but my was 450 pounds and I could not service it myself. Plus it was under warranty.

Not impressed

We bought a Generac brand new & it didn't work straight out of the box. We've had 2 service calls & they still can't figure it out. We're waiting on another part. Parts take forever to get & then you have to call & chevk bc they don't call you. Not happy at all!
