Reliable, well built, delivers when needed, keeps us safe

The GP8000E Generac Portable Generator is the first generator we have acquired. Its no nonsense starting instructions make it easy to start the generator. We read through the instructions completely and started it same day we purchased to validate reliability and our know-how and it started immediately and safely. Instructions are easy to understand and follow. We look forward to having it up and ready to go whenever we may need it. Safety directions are clear and thorough.

Ready!

I found the unit to be well made. As big as it was, it is easier to move than I thought it would be. Well balanced. All features are well marked. I purchased the unit for power outage during severe weather. This unit replaces a smaller unit that could not handle all of our needs. The investment will be worth it when we lose power again out here in the country.

Great Product

Product assembled easily. Materials provided to get it going out of the box. Started up right away -- Very happy with the electric start compared to my old generator. Powers my furnace, sump, refigerator, freezer and hot tub when the power goes out. And I think there is power to spare !! Very pleased.

This Generator went into service very quickly and easily

Hurricane Isaias blew into town and took out hundreds of thousands of homes power. Luckily, I was able to find a strong generator at a great price. I took it home, assembled it very easily and quick, gassed it up and put it into service within an hour. Good thing too, power was out for 4 days and I didn't loose anything in my Refrigerator, or sleep.

Great one pull generator.

I bought this after a hurricane last fall when my other generator acted up. Its a nice generator, starts on first pull. Was able to run freezers, refrigerators and coffee maker :). The only nuisance was the GFI. I had a refrigerator that kept setting it off so I couldn't power it. I understand it is code and safety, but when you need a generator its usually bad weather and GFI's don't like bad weather. All in all a great little generator.

Snap to set up

At this time all I have to go on is the initial set up as I bought this for power outages in our home. If it works as nicely when we have a outage as it did in set up it will give my wife and I a peace of mind which we have not had since we bought a home in this area.

Love the features!

[This review was collected as part of a promotion.] Last year when a hurricane hit we were without power for 3 days. I said then that I would not want to go through that experience again without a generator. I was worried that we would lose all of our food in our refrigerators as well as our freezers and that would be devastating for us. For years I have heard that people had problems with carbon monoxide issues with generators so I was so happy that this one is equipped with CO Sense. I feel safer using this with my family. This generator has an electric start so it is even easy for me to start. I am thankful that I do not have to worry anymore about what we would do without power. In the long run this will save us a lot of patience and money since we will be able to run our refrigerators and freezers.

Very satisfied

I cannot argue against Generac generators. For reliability, dependability and overall satisfaction I recommend getting yourself a Generic. Yes, Generacs' do cost a little more but you get what you pay for. However they are not the most expensive generator company. So, don't skimp on safety and comfort due to price. Go the extra mile and buy yourself a piece of mind. I bought myself a portable generator GP1500E to be sure I have what I need.

Seems great - just bought - missing a piece

I just received the shipment and set it up for test run. The setup was easy (using my tractor to get it lifted off the pallet so I could install the wheels). Started right up and made electricity, so all good. Then ran it back out of fuel and disconnected the battery so it would store well. Overall, all systems go. Needed this size to run my 5HP well and some other selected items during power outages for hurricanes. Couple of points: 1. Generator arrived missing the fuel supply line from tank to carb. I didn't want to call and wait for Generac to ship me one, since I know it was only a $5 purchase at the local auto parts store. 2. It would be nice for the instructions to give a recommended amount of oil to add at initial set up. I had to add a little, then check the stick, and repeat until I figured out it took ALMOST 2 quarts. For fear of overfilling, that took longer than it should.

A Great Portable Generator

New model from Generac. Assembly of the unit was amazingly simple. Directions were very clear except the exclusion of the guideline to attach the spark plug connection to the spark plug, I assumed this was already done before shipping. Start up was very quick and easy. Tested the generator and it ran well and meets all my needs and expectation. Sleek appearance and many great features
