Fired up first pull!

Had to put the wheels on but after topping off with oil and gas this thing fired up first pull. It is somewhat quieter than the Stanley that it replaced. Excellent generator for the money. Output seems to be on the upper end of rating. We run power tools and air compressor of it at jobs site. Works great.

This product has a remarkable starting ability never had one problem

I live in a single home with oil heat and during the winter I need something to run all of the major things in the house if my power is lost this generator for the price is the best purchase that I've ever made it starts every time on the first or second pull I never had a problem with the needing more power than it supplies and if I do overload the circuit The Breakers work and help me to be confident so that my family is not left in the dark

Needed for immediate concerns that we may need it

Having no backup plan for heat and concerns we may lose electricity with forecasted temperatures at -33°. I wanted piece of mind knowing it would sufficiently power our furnace and any other things we need. Started right up on first pull, battery wasn't charged straight out of box when I did initial start, but works now that it has been charged. Great product.

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.

Generac is #1

Gererac was my first choice, spent a lot of dark days before I purchased the GP6500E. Plenty of features, easy setup. I chose this model especially for the Electric Start feature, and the efficient fuel consumption rate. I also matched this generator with the Generac Transfer Switch kit.

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.

Comfort after the storm!

This product was a life saver for me and my family after surviving Hurricane Michael. It’s loud but it does it job and does it well. We were able to keep our house running for day without power. It runs about 10hrs on a tank of gas and it had enough power to run our whole home. Then after our power was restored it was used to help others until theirs was restored. This generator was a great investment, don’t be like my family and wait until you absolutely need it, buy one now and be prepared for anything!

Excellent Generator

The power to my house has been pretty reliable up until this year. We have has three outages for extended periods of time so far this year. I have a well and a freezer full of beef, so I bought this generator to power my house during these outages. The power has not gone out since I bought it, but it does run all my appliances and the well pump without any problems when I tested it. It is worth having the insurance of stand-by power when it is needed.

Best " bang for the buck"

After researching and using other products, such as Honda. I could not help but know that my GP6500 is the best bang for the buck! I know the dependability of generac having owned one in the past ( used it as an enticement on sale of my previous home). This particular model will also give a surge of power when increase of load is needed . With proper maintenance there is no reason it should not last a very long time. Very comforting to know the dependability of the generac name. Living in Florida having dependable back up power is essential. Sleeping better knowing I now have it!

Purchased in the Nick-Of-Time !

I worked hard to find a full service dealer and settled on FD-Hayes, Lansing MI and was extremely pleased with their recommendations for this unit, installation and training. I had this installed on a Monday and literally that Thursday we lost power for 4 days and this unit performed admirably. The safety-switch mechanism on the breaker box was foolproof and the electric start was a real help. I ran it about 24 hours on a single tank of gas, it saved my frozen foods and kept my fridges at temp. I didnt use AC and that is not really a problem as I knew going in that AC would not be viable with this unit.
