gas tank leaking

I have had this 2 years, I have run it 60 hours. The gas tank leaks where it bolts to the frame. It's a bad design or poor manufacturing, Not made in USA for sure. Too many models and design changes to keep track of in my opinion. Just trying to get the tank replaced has taken 6 calls, 3 emails, and still no results.

Excellent features, great price, easy to use especially for seniorss

Checked previous reviews ALL were favorable. Other competitive products could not MATCH favorable reviews & their ratings. Easy of use, especially with electric start & EVEN battery charger, really sealed the deal! Needed an superior generator with all the power outages now & in the future. Couldn't be without an dependable generator anymore! Recommendations from relatives ALWAYS were GENERAC for dependability and quality!

Love this generator

I bought this generator 3 years ago and have lost power 4 times, once for 3 days and it has never let us down. The battery died after the second year and I never replaced it as it always starts with one pull. I always treat my fuel with stabil then shut the fuel valve off with the engine running letting it run until it dies, this assures emptying out the carburetor reducing gumming up issues from hanging around. I run Pennzoil 10w30 motor oil and change it anually. What I really like is the engine adjusts for load so it isn't screaming when there is no load.

Good product value for the money

This served us well during Huricane Sandy when we were without power for seven days. It was easy to set up and safe for residential use. My only complaints would be that it is a manual start with a pull cord which is likely not a problem for most folks but more difficult for an older person. The noise level is a little bothersome too. Overall a good product which certainly did the job well. Next time I would get an electric start and hopefully a quieter model.

Ready for storm

After losing a fridge full of food, we bought a Generac inverter generator. Gp 2200. Ran a few hours break in then switched to synthetic 5w-30 for much better protection from high temps. Can run sump pump, fridge, freezer, washer and gas dryer. Obviously.not all at the same time, used watt meter and two at a time should be ok. Fairly quiet, starts easy, run dry after use. Turn carburetor screw with small hose on it to drain carb bowl. Most important, run ethanol free gas and add stabilizer!

Has all the features to keep our lights on

[This review was collected as part of a promotion.] Glad to have this Generac 8000 Watt Portable Generator on hand and ready for the bad weather season. We just bought our home in a very windy/snow-laden area and having a back up generator is the way to go. It took a few hours to assemble and we found that we needed to go get an additional cord, but once we did that, it started up without issue. The built in maintenance timer is great - makes it convenient to know when to change the oil, etc. The wheels truly are heavy duty. We're feeling confident that if we need it, we'll be able to keep the lights and power going for our kids without issue.

Generac GP6500 saved our groceries!

September 11, 2017, Hurricane Irma headed to Georgia! We lost power at 7:30 a.m. that Monday morning and power was not restored until 11:30 a.m., Thursday (Sept. 14th). Seventy-six hours without power, but the Generac got us through it comfortably. I've never had/used a generator before, but it is easy to start and fairly simple to use.

7500E Portable Generator

Excellent quality and great reputation is what led me to buy this generator. I am thankful I have not had to use it, however it provides a great piece of mind knowing its there if need be. One piece of advice I will give anyone purchasing a generator, secure your garage. My first generator was stole within the first two week of purchase. Since then we had anchors installed in the cement and have it chained down. We also have a place secured by the house if we ever need to use it that we can secure it to.

Great generator for power backup

I purchased the GP7500E to replace a smaller 3250 generator to provide backup power for my house. Last December we had a power outage in the middle of a winter storm, the smaller generator worked for a few items, but I wanted to power more circuits in the house. I installed a transfer switch so I can power the furnace, refrigerator, TV, computer and several lights in the house I assembled the generator, added oil, gas and connected the battery. It fired up right away! I definitely like the battery start! I did a test run on the house and everything powered up as expected, now to wait for the next power outage.
