Rated 4.6 out of 5 by 285 reviewers.
Rated 5.0 out of 5.0 by Great Generator This is the first Generator I have bought and so far I am happy with the purchase! It was very easy to put together. It only took about 15 minutes from unpackaging to startup. It is a little loud, but not over bearing. I shut the power off to the house and started it up on the first pull! It ran great and most importantly it ran the jet pump, furnace, refridgerator, living room lights and TV, kitchen lights and bedroom lights and TV! Everything I needed to run! I used 2 15W energy saving bulbs in each room. One thing they should include is a funnel for the oil. Over all it is a great product! January 8, 2013
Rated 5.0 out of 5.0 by Solid and well built Very well built. Was just what I expected. Ran for 3 hours so far and didn't skip a beat. Started right up on the first pull. This generator is 3 times more powerful than my old generator of 35 years. Could not run the whole house on old generator during power outages. This generator will surely get us through with more comfort. Surprised at how quite it is. Not as noisy as my old generator. Large fuel tank will mean longer run time between fill ups, compared to my old generator. I Can't wait till the next power outage to give the generator a really good test. It is a little heavy but not bad to move around since it does have a handle and wheels. March 18, 2013
Rated 5.0 out of 5.0 by Love the generator!! I purchased my GP6500 primarily to run power tools. I have a large lot which makes it impractical to use an extension cord. I opened the box and followed the instructions on assembly which was easy (putting oil in the machine, wheels on etc.). I put gas in it and it started flawlessly. I have run a 15 amp table saw and shop vac simultaneously with no problem. In addition, I plugged in a power washer and ran it for hours without an incident. When you start it and hear it run you can tell it is a quality machine. It has a lot of power and runs very smooth. I even use it when I have access to power because I like it so much.

Rated 5.0 out of 5.0 by So Far, So Good! I got this generator 4 weeks ago and got my transfer switch wired up just in time for Hurricane Sandy. I lost power for 24 hours and ran the Generac for 10. The 6500 was more than enough to run my fridge, gas water heater, gas furnace, lights and outlets in select rooms with plenty of juice to spare. As a courtesy I powered 2 of my neighbors refrigerators as well. I was also happy with the noise level. I was expecting it to be much louder. I ran the generator in the shed with the doors open and fans running to keep airflowing. October 31, 2012
Rated 5.0 out of 5.0 by Great unit I live in an area that is rural and the power goes out a few times a year. A month ago we had a storm and lost power for about 24 hours. I had a little generator but it was only good for a couple lights and t.v.. Problem is I have a refrigerator, a freezer, and a well pump I need power to as well. Next week I went looking for a bigger more reliable generator and found it with my generac 6500. After I got it home I was actually hoping to have another storm knock the power out so I could see how it would do. Wasnt long and it happened! It was only about a week later another storm came through and knocked the power out for about 7 hours. Long enough to try out the new generac. Rolled it out easy enough even though it's pretty heavy, pulled once and it was running like a champ. Plugged in the necessities and it handled everything. It was so nice to have in that situation. This winter I plan on having a transfer switch so I can run everything from lights to heat. I'd recommend this generator if your looking for one. September 22, 2015
Rated 5.0 out of 5.0 by 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. September 13, 2015
Rated 5.0 out of 5.0 by Thiis is the one I have the Elec start model, the battery holds for many months with out a recharge. If you do need to use the rewind starter, it starts on the 1st or 2nd pull. September 10, 2015
Rated 5.0 out of 5.0 by Great features, easy to use Perfect for occasional power outages or camping, easy to use, easy to start, just a great little generator August 28, 2015
