good stuff .

I have not used product yet. I bought it as a replacement for a 3500 wen , which did a good job. After comparing it with other products of the same size and price range I decided on the Generac . The good reviews and recommendations are another reason for my purchase.

Greatest thing since sliced bread

There's nothing I can say that would even come close to doing this machine justice , bought another generator from a competitor , biggest mistake I could have made. The features, durability and quality is second to none , highly recommended this to anyone over any other brand .

Not bad for a mid size.

Bought a GP3600 model today. We lost our electricity in a storm 4 days ago. Easy to assemble, started right up and is powering our fridge & some lights. Nice smaller unit. Very portable & not very loud. 4-20 amp duplex plugs & 1-30 amp locking plug. Not a bad value if it holds up.

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.

Awesome product

[This review was collected as part of a promotion.] I've been wanting one of these for awhile now! Living in Ohio and having your electric go out during the winter is horrible! Now if it goes out I am able to keep my kiddos warm! I highly recommend this! I used it on my friends RV over the weekend and it works amazing! Love it.

Excellent Generator

Generac makes a quality product at an affordable price; plus I prefer to support American made products. I bought this model on sale for $800. In the past 15 months, I've only put 75 hours on this unit to date (although it ran for 72 hours recently with several cooling/fueling/oil check breaks - at 40 hours, I hadn't burned a drop of oil but I did the first oil change). Basic maintenance is simple enough for anybody to perform. The GP8000E feeds my main panel and powers everything I demand in my house, such as my pellet stove, electric range, well pump, lights, microwave, outlets and TV. I haven't tried powering my hot water heater but at 5,500 watts, I think it would do just fine if I shut some stuff off. It sits approximately 20 feet from my bedroom; the noise is barely noticeable when I am laying in bed. I do ensure that my carbon monoxide detectors are on whenever I have this unit powering my house. It's much more fuel efficient than I expected, averaging around 2 hours per gallon of fuel. With all of this being said, I do hear a bit of occasional surging once the temperature hits 25 degrees or below but it has no performance issues. In my opinion, portable gas powered generators are the way to go for powering a house during an emergency. Natural gas isn't an option in my area so we are limited to propane; getting a propane delivery after being without power for a week isn't always an option!

Nice Generator

This little GP6500 / CO sense technology performed perfectly for the 2 days we needed it much better than we expected.Easy assembly,oil fill and gas fill no issues. First pull started right up! Powered every circuit. Refrigerator,Freezer,Window AC,Cell Phones charged and several lights on keeping us safe,our food cool and frozen. Thank you Generac for making these units quickly available for purchase as needed to power up after a major storm left our area look like a war zone of downed trees,power lines and heavy property damage.

This is a great generator!

Come January 2021 this unit will be one year old.Every three months we charge it for 24 hours.When ever I go out and start it up THERE are no problems what so ever.I like to run it ever so often so I know all works find.We are lucky that we have not needed to use it for a back up yet!!You see we live in Northern Ontario Canada where we get lots of snow and very COLD weather! I know if and when the time comes this unit will stand up to it's job.

Mighty Powerful Standby

First of all Generac is the best. I have purchased many industrial generators for hospital backup. I know that Generac is quality. This unit meets all my needs for home backup without having to go to s standby unit. It was easy to assemble and started right off the bat. Much quieter than expected for its size. This unit is well built and I am sure will last me a lifetime. Fuel tank capacity and placement are optimal and I really like the built in strainer. I am very please with this purchase.

Love the first 8000 but the second generator let me down.

170 hours on generator -two months old Stopped producing power. Not happy. Power would come back when I jumped the field with a drill - spinning it backwards. Brought to a dealer rep - we will see what they find. Hoping it will be under warranty without a battle. Walpole,MA
