Good quality

I really like the product, however the Owner's Manual and installation was hard to read and did not adequality explain and was hard to follow. The Unit id Label was hard to read because it was too close below the generator. It would be better with larger illustrations and more views.

General saved us during Helene's aftermath

I bought this in the aftermath of Helene devastating western North Carolina. We needed a larger generator that could operate several without needing to unplug items so as not to overload it. My Generac GP 6500 had no problems carrying a much larger load as we were without power 11 days. I was able to use a medical CPAP at night without worry as the refrigerators and freezers and lights were able to work with it and also charge phones and other necessities while operating as close to normal during that time. I've used it during several power outages since. A great generator to have.

Piece of mind

I opted to buy a portable home back up generator opposed to a built in because of the versatility. It will do the job of a built in but I have the option to use it for other things as well as loaning to someone else if I haven’t lost power in the event of a hurricane or other natural disasters. Upon delivery I was impressed with the ease of set up and overall performance of the generator. I expected it to be very loud but was actually surprised that it was not unbearable. Overall very happy with the purchase and not as anxious with the upcoming hurricane season starting.

I love it.

I bought it almost 2 years ago, I haven't had to use very often, only when power is going to be out for a while, but it runs EVERYTHING in my home. No need to shut of anything, just hook it up, push the electric start, and throw the switch in my breaker panel. It's not one of the quiet ones, so I keep it about 100 ft from my home inside my barn and I don't hear it at all.

Works well; good warranty

I bought this product brand new after our home was impacted by Hurricane Helene. The generator worked great, but the fuel gauge was defective, causing a lot of undue stress and complications. It has since been fixed under warranty, but it was not something I thought I would have to deal with.

If it works it works. But that's if it works

After long storage battery dead. Customer service said had to disconnect battery we will ship a bra one. Well off days off storage so it should cut off the battery. I read the manual says on will drain it turn off. Nothing about discount. That was last fall. Took battery out Month ago one start was great left battery in month later won't start. Even with new battery. Plug is super dirty and chipped. Got a new one to put in this weekend. I am sure it's going to be a tough start. Now does a plug get so dirty on 38 hours of use? Going to change oil too. Don't know where fuel filter is either manual won't say and it doesn't look like a car filter. Also that list the part number for the plug but can't find out what type. I thought generac was a good brand. I was wrong. I wish I got a different brand that just starts up. I lost everything in the fridge because this refurb can't start past 38 hours of run time. Right now it turns but doesn't turn over

Do your research and then buy this one.

I had purchased a Westinghouse Generator and it had all kinds of issues. Before I took it back I did finely get it to run. I don't know who makes there motor but it just sounded very cheep, loose and claney took it back Fast forward I decided after researching several other top notch units I decided on this Generac GP8000e. I was missing things not in the main box but the place I bought it from supplied it all so all was good. I connected the battery, it was charged up, added the oil added mid grade gas, turned on the gas flow to the carb and it started right up and this motor is tight and sounds like a top notch motor. My only regret would be the tool kit that Ace gave me was the cheapest 2 wrench's I think I have ever seen in my life and I don't think they are relevant to anything. i was also missing oil and they gave me Pennzoil and not Generac oil and I heard Generac is the best. Buy it you you wont be disappointed!!!

Great generator, easy to use.

Great generator...Electric start is easy to use and starts right up..I bought this with the internet for my wife to use if the power goes out and I'm not home. Only gripe I have us with customer service.My generator was supposed to come with a 25 Amp extension cord and it didn't. I talked to 2 service reps who claimed they sent the cord.Still have not seen the extension cord.Besides for customer support,I love the generator.

Fantastic

[This review was collected as part of a promotion.] Oh wow! What an amazing opportunity to try this. We did use natural gas in this just to try it out and it was incredibly powerful! The unit is noisy but not so much that it would be a disturbance. Our old generator was much louder. This unit is quite compact and easy to move around. It will definitely come in handy when the power goes out! Love that it takes 3 different types of fuel too. Very convenient. Generac is such a trusted brand that lasts too!

Excellent generator. First time owner, couldn’t have been easier!

[This review was collected as part of a promotion.] I haven’t used a modern generator before - last one we had was 25 years old, was noisy, shaky, and we’d wear ourselves out getting it to start. Oh, and then there was the exhaust, smoke and low current. Not anymore! This thing is a dream. Arrived well packaged and was a breeze to set up. Basically you attach the wheels, front rests and handle and it’s ready to go. Well you add oil (included, along with a handy funnel) From there, startup instructions are well documented in the book AND on the generator itself. I really appreciate that there are easy to follow graphical steps on the unit itself for starting and running the unit. A few quick pulls and it was purring like a kitten. I haven’t had a chance to put too much load on it, but so far it’s easily powered everything I’ve thrown at it! The unit is heavy, feels like everything is high quality, and I expect it to last a long time. Definitely recommend!
