Very simple to start and use.

No brainer start and stop generator. I researched generators to buy and always settled on the Generac. Then I stopped by my neighbor/electricians house to see his setup and he had the exact model Generac I had planned on purchasing. He endorsed his model and installed mine and I couldn't be happier.

It would have been great if all the parts came with this generator

Missing parts out of the box. Cannot put the unit together properly. Will try to contact the company after the weekend. Would love to be able to move this unit from where it was delivered but cannot install the wheels without the axle. I hope this isn't what the rest of my experiences are going to be like.

Best helper at the worst time!

I am not a big fan of generators running in the nights disturbing our good neighbors. But, due to the increased power shutdowns, it became an essential part of our daily life. All the features of this generator are excellent, other than its sound level in our quiet neighborhood.

Looks good, runs like a charm, easy maintenance.

No more worries with bad weather with my Generac gp 6500. When a storm is coming, I just install my generator, fill it up with gas and wait for mother nature to do her worst. My wife and I cuddle up in the sofa next to the fire place and look out to see the lightning show listening to classical music. it's better than fireworks on the holidays. Meanwhile we still have our well pump hooked up, the micro-wave and coffee maker if need be, and, can't forget the computers, tv, phones and lighting available. It's simply wonderful.

Good value for the features

We chose the 6500E over other models due to it's many positive reviews from multiple sites and its features for the price. I especially like the number of available 20 amp outlets plus the 20 foot power cord. I specifically wanted the electric start and the automatic voltage regulation, and the rubber outlet covers are a great addition! Cons: The set-up instruction card had several minor errors and omissions. For example - the set up instructions did not mention that the fuel line was disconnected at the shut-off valve and needed to be connected by the owner. Good thing I saw it during my initial inspection. Suggestions: An onboard voltage meter (and maybe a manual voltage adjustment) would be a great addition, so the output voltage can be monitored without needing a separate meter. And it would be nice to have an onboard power meter showing amperage draw. But, for the price this model is perfectly adequate for our needs. Unfortunately, the week we received our generator, the price dropped $50. Wish I had waited one more week.

Better than I thought.

Needed to go with a larger unit than what I had due to geothermal system. Wanted something to fill up, plug in, and hit transfer switch. This unit gives me ample power for the heat, a/c, well, and the other critical needs. Would like to had a home standby unit but could not justify the cost due to where electrical service was and where gas service was located. The hookups were the killer for a home standby unit, not the cost of the unit itself. This unit will provide everything I need and then some. Have not run full load test yet but smaller loads were handed spot on. Usually power outages in our area run 5-24 hours so this unit will be great.

The GP6500E is just what I needed for my 5th wheel camper.

I had researched different generators for use with my 5th wheel camper. I wanted a output range of 6000 - 7000 watts. In looking at the various brand that were available on the market I found that the Generac GP6500E was within the range I wanted. It had the option of battery or pull start with a battery wall charger. There was a 120/240 twist outlet that I would be able to use a twist adapter to convert to the existing power cord on the camper. The large capacity fuel tank would give me longer times between fill ups. With the additional four 120 volt outlets I could also plug in any additional electrical component outside the camper. My determining factor was that Generac makes generators of all ratings and uses and that they would have the dependability and reliability that I would need. They also have a toll free number to call for service 24/7.

Excellent generator

I bought the GP7500E with electric start the night before storm Sandy hit NJ in 2012. I ran it 14-16h per day for 10 days without any issues. I did not follow any of the recommended maintenance such as oil change or drain the fuel tank when it was sitting outside for 5 years more or less unused. We then moved to CO and after getting off grid land in WY a decided to get it started. All fuel components except tank needed to be replaced including the carburetor. I replaced the spark plug and oil. After letting the carburetor get fuel for a few minutes it started on first pull! I replaced the battery and it start with just a short press on the start button. Only issue is the hour meter is now blank and shows to run hours. If the generator can take my misuse it can handle anything. I'm very pleased with it.

Powerful Generator

I purchased this portable unit about 3 weeks ago, and it is a wonderful generator. I do have a few issues with it though. First off, it is way to loud. I had to build a house for it about 100 ft away from the house to avoid hearing about it from my neighbors. My other issue is being able to read the fuel gauge to know how much fuel is in the tank without me having to look directly inside the tank. I had a GP3250, and it was very easy for me to read the fuel gauge, but the fuel gauge for the 7500E is not reader friendly. Besides those issues, I have to admit that it has a lot of power to keep your house powered up for a lengthy period of time.

Great product

[This review was collected as part of a promotion.] Overall we have loved having this generator around. We did test it out with a few power tools and it works great. We have it ready to go for the rest of hurricane season. Right now we have used it for minor stuff just to test it out and so far it seems to hold up great. It is not overly loud for a generator. I will say it is really heavy and I am glad it has the handle to push/pull it. I am even more glad its handle can be moved in different positions.
