I've just received the generator last week and have tested it for about 10 minutes. It worked perfectly, but I'm yet to test it out in case of a loss of utility power over several days! Since I selected this model, I feel it will come through in powering up the essentials of the house with no problem.

We purchased this generator to serve both as a power back-up to our house; and for ad-hoc use on the farm in locations where we don't have power. We have gas furnace and water heater so this size (7,500 watts) is big enough to run our well pump, sump pump, furnace, water heater, microwave, and two rooms worth of outlets. We are using a transfer switch so all we need to do is wheel out the generator and plug it in. The assembly is pretty basic (wheels and handle) went fairly well (its heavy). The oil filler cap could be in an easier area to get to (you will need a funnel to get oil into it). Once it was gassed and oiled up it started after just a little bit of choking, and after that it starts the first time every time with the push of the electric start. So far we haven't really taxed the generator yet but it has run well so far. I saw the comments in other reviews about gas leaking but I simply switch the fuel supply to off (with the easy to get to lever) and let the engine run a bit until it starts to sputter and then turn it off and there are no fuel leaks (better for longer term storage this way also). Thus, so far so good and seems it will work well for us - hopefully we never have to find out!!

Have owned this unit for 16 years. Very particular about maintenance, so it has never let me down, always starts first try. Big enough to power entire house, including central a/c. Ran for 55 hours straight in Hurricane Irma 2017. Annually, just before Hurricane season, do oil & filter, spark plugs & air filter. Only store with non-ethanol fuel, and run carburetor dry at shutdown. Lives in garage under a large cover, looks like day I bought it.

Best value for price. Easy assembly. Started right up. Ran my pool pump, kegerator, deep well cooler, 1 window ac unit, 1 in wall ac unit with ease. It didn't even strain. Refrigerator and house lights are on solar, battery backup system. I did not try running central ac, stove, although it probably would if other loads were shut off. Connected my oscilloscope while under load. Voltage and frequency right on. Very clean pattern. More than happy with power output, quality.

I have not used the generator in an actual power outage situation but when I ran a test it performed really well. I should have paid the difference and got an electric start but that was my mistake. It's a little loud but no more than expected. I believe it will meet my needs for a back-up during power outages.

I am a female, own a home and needed a generator I could handle in an emergency. I am able to move this generator, fill it and start it with no problems. It is reasonably quiet. It runs for a significant length of time without needing a refill (+/- 6 hours). During a weeklong power outage during a tropical storm, it kept my refrigerator on, my sump pump going, some lights on and I was able to charge my cell phone. It did everything I needed.

[This review was collected as part of a promotion.] This generator is absolutely amazing! The quality is awsome and holds up great. The best thing I love about this generator is that it automatically monitors the co levels and shuts it down if it's too high. I have small children so this makes me feel so much better knowing that it's safe. Another thing that's great is it comes with the cord that you need for it. A lot of generators you have to buy that separate. Overall this is a really good generator to have. I recieved this as a sample and this is 100% my own opinion!

We recently purchased the Generac GP6500 and couldn’t be more pleased with this product. This generator had its fair share of use after the recent damage caused by hurricane Florence in the coastal region of Eastern North Carolina. The GP6500 generator was easy to assemble and started up on the first pull out of the box. The generator ran continually throughout the daytime hours for a solid week after the hurricane had passed through our area knocking out power to our subdivision. We had NO issues or complications with our Generac GP6500 while we were waiting to have our power restored. Also, we noticed that the full burn of the generator seemed to be more efficient than expected. This was a major relief to us since all gas stations in our area were closed due to lack of available refueling trucks as well as there was no electricity to operate the gas pumps at the stations. Not having to worry about running out of gas for our generator was very reassuring. Not only did we use our Generac GP6500 after we lost power at our home we also continued to use it as we participated in various clean-up projects for others homes who suffered severe storm damage in which utility power was not able to be restored. The GP6500 was small enough to be transported to various worksites as home repairs were needed throughout our region. Again, we used our generator all throughout the day while we operated electrical equipment to assist with clean up and various home salvaging activities. We’ve since winterized our Generac GP6500 (which was simple and easy to perform) and have it stored and ready for the next time it is needed. Unfortunately, living close to the coast in North Carolina results in yearly threats of hurricanes. However, we are comforted knowing that we are prepared for any future storms and power outages with our Generac GP6500 ready to go in the garage. Good Job Generac!

I use this generator five days a week, all day long. It is a work horse. My only complaint is that the electric start is not dependable. Since the generator starts so well with the pull starter this is not a deal breaker. It is of interest that I've had a few Generac 8,000 watt electric start generators and they all have electric starters that are flaky. Since they pull start so well I live with it.

Bought the Generac 6500E as a back up for my home. I live in New England and Power outages during the winter can be frequent. Spent 3 weeks without power the year before last and Swore that wouldn't happen again. Fortunately Did not loose power this year, but I am prepare now for the future. Product is reasonably priced, starts right up with the push of a button and runs without a hiccup. Only thing is I wish that it gave the option for alternative fuels, such as propane. Would be a nice back up incase gas stations are closed.
