Easy Setup, Well Built, Runs Great

I picked up the GP 6500E generator today. All parts were present and the assembly was easy. The unit started right up with the electric start. The generator appears to be well built and has good operating directions. It ran my power tools without a blip. The wheels and pull handle makes moving the generator on the ground easy but it isn't lightweight. It takes two people to lift it into a pickup. A separate battery charger is included as the electric start battery is not directly charged from the generator. I'm impressed so far and look forward to many years of usage.

Amazing

[This review was collected as part of a promotion.] This Generac Generator is amazing!! We live snack dab in the middle of Florida and get so many hurricanes each year. This powers most of our home and runs for a long time. Highly recommend this generator!!

Works nice

[This review was collected as part of a promotion.] Look like it's pretty easy to maintain. The noise level isn't too bad. I will add a video later of that. It is heavy and once you get the wheels on in the handles, it makes it a whole lot easier to move around, but you still know you're moving something because it is heavy. It works very nice. I really can't say how it's going to hold up. I can update that later, but it looks like it's made very well and at any time you have any problems I don't know what's going on. It has a one 800 number for you to call and they will help you out and I love that. It has a five year warranty And that it runs off of propane ,natural gas or gasoline. And this is the perfect time for us to have a generator with the electric going on and off with all the storms and everything. I am so happy with this.

A work horse for the Mid-West weather!!

After the several months of Severe Mid -West weather and constant power outages! We up graded our generator to the GP6500. It was very easy to set up as well as to use! The features that is nice to have on this unit were the large 7 1/2 gal gas tank, easy to pull start and power to supply my entire house!! This unit is not only great for home back up power but we also took it on our hunting trip and made the trip just a little more like home!

Works just like is it supposed to.

Bought this almost a year ago, worked well, although I only had to use it the one time then. Power company trimmed all the trees over the lines last week, so I don't know if I will ever need it again. Glad to have the b/u though. I know it will work next time because it is a Generac

Great Generator To Have After The Storm

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!

Good value for a high quality product

This unit has everything I need for home backup. It's a heavy machine but the pivot handle makes it easy to move around. I also like the never flat wheels. The only drawback is the lack of clear instructions for changing oil and draining fuel. The instructions are vague for a novice like me. I need more detail and better drawings. Well worth the price I paid for home backup.

Excellent Generator-Generac GP6500

Bought this Generator used with 100 hours in it (4 days of use) got a great price and looks and works like new! I can run everything in house, all lights, electric stove (not oven), heat (furnace) & hot water heater. Haven't tried to run the central air unit yet but the heat and hot water is more important, anyway I ran everything with no hesitation or strain on generator. I gave it a 4 on features because I wish it had a voltage meter on it otherwise all 5's! Full tank of gas you should get 8+hours run time with everything I described above, I Love this Generator and now ready for any outage, may not need for 3 years but will be ready when it happens.

Great!!

[This review was collected as part of a promotion.] Compact, reliable power. This GP9500E from Generac has a small footprint, yet packs some serious power. This is capable of running on gasoline, LP (propane) or natural gas. Rated at 12500 starting watts and 9500 running watts when running on gasoline. The 500cc OHV (over head valve) engine features electric start with the included battery, as well as the old school pull start just in case the battery or something fails. It holds 7.5 gallons of gasoline and will run 9.5 hours at 50%. There is an included 4 foot long LP adapter hose and a 20lb tank will run 4.5 hours under the same conditions. Propane will lower the output slightly at 11250 starting and 8550 running watts. If you run natural gas it lowers it to 9000 and 7000. The included handle and wheel kit makes it super easy to move it around when needed and the handle folds down to store neatly. There are many great features built in, such as covered outlets for added protection when being used in the elements, CO sense technology that will shut the machine down if CO levels get too high and a low oil l cel shutdown that will stop the engine if it detects low oil to save the engine from damage. It is also compatible with HomeLink manual transfer switch kit to help power your home in the event of a power outage. This is especially helpful at our house as we have a well and when the power goes out, there is no water. So this adds peace of mind in those situations. Setup was simple with the included directions, which are also printed on the top flap of the box. Everything you need aside from a couple of very basic tools is included as well. The front panel contains an hour meter to keep track of how much use the machine has had. When running this is on the quiet side for a machine of this size. I am extremely pleased with this generator. From the ease of setup to the ease of use this generator is awesome.

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 .
