What a beast!

[This review was collected as part of a promotion.] The GP6500 Pull Start, COS W/Cord 49 St is a beast, simply stated. This thing is powerful and it shows in its size. It hooks up so easily and really is ready to use as soon as you get out of the monsterous box! It is easy to read instructions too. You can power multiple things around your house easily and for hours. I live in a hurricane path near the Gulf and this will come in handy for years to come. It does weigh 200+ lbs so have someone with muscles to help you out. Once its out of the box its very easy to get around using its wheels. I am in love with this machine!

Best portable generator

Have owned this unit for 16 years. Very particular about maintenance, so it has never let me down, always starts first try. Big enough to power entire house, including central a/c. Ran for 55 hours straight in Hurricane Irma 2017. Annually, just before Hurricane season, do oil & filter, spark plugs & air filter. Only store with non-ethanol fuel, and run carburetor dry at shutdown. Lives in garage under a large cover, looks like day I bought it.

Can't wait for a power outage now!!

As a homeowner, I am thrilled to have the generac generator. It was really easy to set up and it starts so easily with the electric start. Having a quiet muffler was also important to me. It' a convenient size to store in my garage and pull outside as needed to use.

Should do what it is designed to do

It was a gift from a son-in-law. I have started it but have not used it as we are still trying to get our house wired for it. One complaint was that the manual with it was not very good so I had to down load one from the web site. Also it arrived without the axle but when I called Generac they shipped one right away.Since it is so heavy I had to get help in installing the wheels and axle. The Generac people(Power Solutions ) in Jasper, GA did send a man over and he did the work for me and made all the proper assembly needed and was very friendly. This generator is to be used in case of power outages that we have often..

So far, so good

Bought this in the summer before we really needed it. Last winter, we were without power for 3-4 days after an ice storm. You couldn't find a generator at any store for miles around. We ended up using small inverters hooked up to the vehicles to power our deep freeze. I haven't used this one yet under load, only to make sure it started and ran a power drill. So far, so good.

Great product, great features, great price!

This unit replaces our 14 year old Generac 4000XL so we knew about product quality and support. This unit is connected to our service panel and can run everything we need in the event of a grid failure! My only complaint is that it does NOT have an idle control like our 4000XL, so it will not use fuel as efficiently. That said, we would still highly recommend this generator.

Standby capacity in a portable unit

We purchased this unit as a whole house generator for those extended outage periods, usually 1-2 per year. Since we do not use gas (propane or LNG), we did not want to install a standby unit on a concrete pad and find a place to hide a couple large tanks. At about half the price including a transfer switch, this unit will power our entire house and we can still store it in the garage or bring it to a family members house in emergency. Keeping 15-20 gallons of extra fuel on hand if stations are out might be a challenge, but for the rare occasions that happens, we'll manage just fine.

Mighty Powerful Standby

First of all Generac is the best. I have purchased many industrial generators for hospital backup. I know that Generac is quality. This unit meets all my needs for home backup without having to go to s standby unit. It was easy to assemble and started right off the bat. Much quieter than expected for its size. This unit is well built and I am sure will last me a lifetime. Fuel tank capacity and placement are optimal and I really like the built in strainer. I am very please with this purchase.

The product is well worth the price I paid.

I have not used the generator in an actual power outage situation but when I ran a test it performed really well. I should have paid the difference and got an electric start but that was my mistake. It's a little loud but no more than expected. I believe it will meet my needs for a back-up during power outages.

Very nice generator

I bought this GP7500E to replace an old Coleman generator I had, and I'm very impressed. It's quiet, it assembled easily (install the wheels, install the handle, hook up the battery, add oil, add gas, and done!), and it powers up my house easily. Here in Nova Scotia power outages have become so frequent that a generator is necessary. The only thing it won't run is my electrical baseboard heating, but no generator even approaching this wattage or price range will do that.
