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.

Powerful, Flexible, and Reliable Backup for Hurric

[This review was collected as part of a promotion.] I’m really impressed with the Generac GP9500E Tri Fuel Generator! It’s very well-built and feels super sturdy. It is quite heavy, though, so I definitely recommend having two people to lift it if needed. Once you get the wheels installed, it becomes much easier to move around. The setup was pretty straightforward, there aren’t too many pieces, and I was actually able to put it together by myself, though it would go faster with two people. I’m especially glad to have this generator since I live in Florida, where hurricane season can easily knock out the power. Last year, we couldn’t use our submersible water pump to prevent flooding during a storm because we lost power, so having this generator as a backup gives me so much more peace of mind. I also love that it runs on gasoline, propane, or natural gas, just with the turn of a dial. It’s super flexible and reliable, and I love that the COsense technology adds extra safety by automatically shutting down the generator if dangerous carbon monoxide levels are detected. Overall, I’m really happy with this unit and feel much more prepared for the next hurricane season!

Great Generator!!

I purchased this generator after doing some research and felt this to be the best generator by far for quality, features and price. I had used a John Deere that I paid almost 1500.00 dollars for after we were hit by a severe ice storm in 2003. The John Deere was junk compared to this Generac. The John Deere will not stay running if left in the rain or if snow blows in on it. Also the quality of the John Deere was cheap!! It had a plastic gas tank, no electric start or anything to keep it off the ground. The Generac comes with the electric start (which is great), wheel kit, a solid frame and a handle to move the generator around with. Shop around and compare you will end up buying the Generac!!

Just what I was looking for

Bought the 6500E after the last ice storm and power outage for 5 days. Although I didn't have to use it for the latest winter storm (thankfully), the ease of set up and start up was great. I just ran it for a little to make sure it was gonna be ready if needed and it was everything I thought it would be. Not too loud and would easily handle my emergency backup needs.

Outstanding Performance

I bought 3 years ago and used it this past 3 days straight with no issues. I ran 3 refrigerators, all the lights in the house, garage door openers, electric heater, coffee pot, and toaster over. Really impressed with the power output. Plus the tank is fairly big, and last a long time once topped off. Only con is that it is really loud.

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

Except for a minor cliche generator came through in 2 emergencies

Generator was purchased during the Northeast's infamous "end of August 2011 storm" and provided excellent whole house emergency power throughout that week long period, and the subsequent week long storm emergency the following October. The only complaint is that the fuel turn-off valve knob broke off when turned off. Aside from the inconvenience of transporting it back to the dealer, the problem was quickly rectified under guarantee and with out question.

Generac Is The Way to Go

[This review was collected as part of a promotion.] During a recent power outage, my husband was able to connect our Generac GP Multifuel Portable generator to the breaker box. Worked perfect for powering the house. Generator was also great using power tools on an outdoor project.

POOR WARRANTY AND PRODUCT

I bought this generator just under a year ago. We were expecting power outages up to several weeks. Glad that we weren't effected. The reason for my 2 stars is the Generator is supposed to have a great warranty. Buyer beware, after putting the generator together and trying to start it the generator failed to start. I called to have someone to come out to check the generator and was told that I had to bring it to a place. So a generator that weights over 100lbs with a full 7 gal tank of fuel they expected me to transport over 25 miles to have it serviced. I would NEVER buy another product from this company.
