Fast and easy setup, high expectations!

Pre read the manual online the day prior to delivery which made the startup effortless. Assembly was a breeze and it srarted right up with ease. Ran it for about 30 minutes, loaded an air compressor, portable heater, and shop vac just to test. Then tested the whole house, 2 fridges, freezer, furnace, gas water heater, and numerous lights. Flawless performance. Expect to survive the eventual power outage this winter and next spring.

Won't start.

I bought it at Sam's Club (06 JUN 22) and assembled it per the instructions. I fired it up once and it ran for a few minutes. When I shut it down and attempted to restart it, it wouldn't fire. It just makes backfiring noises. It still doesn't start or run. Needless to say, I am not pleased! Your phone rep was supposed to forward me a list of authorized repair shops, but I have yet to receive it. I want my generator to run in event of a power loss. Please help me to reconcile this situation.

Reliability!!!

I purchased this product after reviewing several manufacturers. I was looking for a size that could provide most of the convinces we are used to in the event of an outage. I have a Generic 4000XL that was good but not big enough. We had a six day outage due to a tornado that left most of the city without power. The 4000XL failed in the first five minutes due to a winding wire that got caught in the armature and shot the voltage regulator. This outage convinced me to double the size of the unit as it became a nuisance switching power cables. It would be great to be able to afford a standby natural gas unit but resources are tight. This unit performed very well!!! Even though it is battery start, it started easily manually and on the first pull!!!! Now I need to see if the 4000XL is repairable for smaller building projects that do not need lots of power.

Works great

Bought as an upgrade to a small generator during hurricane Irene (used with extension cords to keep fridge/lights running. We had an electrician hard wire the 7500E to the house in time for the October snowpacalypse (15.5" of snow, power out for 6 days). We have over 180 hours on the generator in 2 months, but for the last storm (6 days out), we were quite comfortable, and were able to run the dishwasher, septic pump, stove, etc. The power being out became a minor inconvenience. Aside from the quick *pre-dark* oil changes, no real maintenance beyond filling the tank twice daily. Very happy with the generator, and have already recommended the same unit to friends.

This is the one!

I bought this unit because I am building a house in the country. Com Ed won't have power there for another month. It took all of 10 minutes to put this together. total 15 minutes from box to running. Loaded it on the 1st start, Wow, this will run everything I need it to. Then after the house is built, it will serve as a back up in power outages. Illinois doesn't have the best of winters out here in the country. I recomend this to any one serious about a quality generator!

Good Product from Reviews Haven't Used

We purchased item and it took longer than expected to receive it and that was frustrating considering the price we paid for it. We haven't got to use the product yet as we just picked it up from the store on 12/08/2021 which was more than a month since we purchased it. We will update more if we actually get to use the generator this winter more than just starting it.

Advice about generator safety that everyone really needs to be aware with.

I have something to explain to everyone about how people use their portable generators during a power outage. A good decision is to have every house have a backup generator installed already which is a home standby generator or a solar panel. Home standby generators are safer because they use natural gas while most portable generators use gasoline which gives off carbon monoxide and not only that. They also injure people if used incorrectly. Many people have died each year when using portable generators due to carbon monoxide poisoning and electrocution. Remember not to run your generator indoors. Running your generator indoors is never safe. That will increase the risk of carbon monoxide poisoning which causes death. Always use your generator outdoors please. Make sure that your generator is 15-20 feet away from house and away from doors, windows, and vents. Some people also run their generator in wet conditions which can electrocute them. Here’s an advice about generator safety: please remember that you should never run your generator indoors. Remember that carbon monoxide is an odorless and colorless gas that you cannot see or smell. Carbon monoxide is a silent killer. Keep that in mind. Make sure your generator is 15-20 feet away from your house and away from doors, windows, and vents. Having a carbon monoxide detector is very important against generator safety. Some people also allow children to go near the portable generator which could pose risks. We need to keep an eye on our children making sure that they are not near the portable generator so they won’t get electrocuted or burned by the generator which is dangerous. A locking enclosure also keeps kids safe. A generator shed might look like a tempting place to explore, or take cover during a game of hide-and-seek, but a generator is a dangerous piece of equipment that can cause injury. It says on the manual that we should also keep children away at all times from the portable generator to avoid injuries. Generators pose electrical risks. If you need to use your generator during wet weather, you need a generator tent to protect your generator from getting wet. Don’t let your generator get wet. Keep your generator dry and before using your generator, please make sure your hands and your generator is dry. Everything that is said on the generator’s operating manual should not be ignored. Never smoke cigarettes near the generator. Please keep flammable things away from the generator. Never overload your generator too. Your generator can catch fire. Never ever try to plug a generator cord into a wall outlet to avoid back feeding. Back feeding your generator is dangerous. Always turn on your generator first before plugging in appliances and shut off the appliances before turning your generator off. Use a heavy duty cord for your generator and the cord should not be worn out. All the instructions should be followed carefully. Never refuel your generator while it’s running. It can cause fire if fuel spills while your generator is hot. You should turn off your generator and let it cool off before refueling it. This is only a reminder for everyone’s safety of using generators. Make sure your generator is properly grounded. This is only a reminder for everyone’s safety and for everyone to know about. Thank you hope you stay safe as well.

Like all the features it offers

Had a hurricane coming our way so decided to purchase a generac because of its reputation. Set it all up and tested it out, but never used it because the storm turned and headed up the coast. We at least have comfort knowing we are covered if another storm heads our way, which is likely because we live in Florida.

Great generator for price

My GP8000E generator was delivered to my carport in the box. It was easy to set up. Since there's no gas in the tank, we just leaned it back on it's side, allowing us to put the wheels on without picking up the generator. My husband and I had it together and running in less than an hour. I love the electric start. It's not as loud as I thought it would be. Not had to use it after a storm (hope I never do), but so far so good. I crank it up and use it every two weeks so don't have to worry about storage. It powers the coffee pot and air fryer without blinking an eye. I searched and searched for a generator made in the U.S.A., and Generac was the most made in the U.S.
