Best of the best...

If looks meant anything, this is a killer of a generator. I took back a B & Stratton, then bought this. Works great, easy to set up and works flawlessly with the your Manual Transfer switch. Generac is second to none when it comes to generators. Jeff M.

One Happy customer

Other than having poorly written instructions, we love our new generator 6500E. Since we are in a flood zone and it seems we are having more and more power outages, we look to buy a generator that could not only power our lights and refrigerator, furnace, but also our sump pump when needed.. It came the same day Hurricane Sandy caused our power to go off. Our electrician helped us in the pouring rain get it started since we found the instructions not very informative.

First time Generator Purchase

Bought the Generac 6500E as a back up for my home. I live in New England and Power outages during the winter can be frequent. Spent 3 weeks without power the year before last and Swore that wouldn't happen again. Fortunately Did not loose power this year, but I am prepare now for the future. Product is reasonably priced, starts right up with the push of a button and runs without a hiccup. Only thing is I wish that it gave the option for alternative fuels, such as propane. Would be a nice back up incase gas stations are closed.

Built Like a Tank—Ready for Anything

[This review was collected as part of a promotion.] The Generac GP9500E is a beast. Tons of power—easily runs the essentials plus extras without breaking a sweat. The tri-fuel setup is a game changer. Whether it’s gas, propane, or natural gas, it fires up quick and runs smooth. Noise-wise, it’s not whisper-quiet, but for the power you’re getting, it’s surprisingly reasonable. You’ll hear it, but it’s not going to rattle your teeth. Maintenance is straightforward—keep up with oil changes and check the air filter now and then, and it’ll treat you right. COsense is a solid safety feature, and the build quality feels like it could survive a small war. Or a zombie apocalypse—because let’s be honest, if the world ends, you’ll still have power while the neighbors are burning furniture.

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.

Comfort after the storm!

This product was a life saver for me and my family after surviving Hurricane Michael. It’s loud but it does it job and does it well. We were able to keep our house running for day without power. It runs about 10hrs on a tank of gas and it had enough power to run our whole home. Then after our power was restored it was used to help others until theirs was restored. This generator was a great investment, don’t be like my family and wait until you absolutely need it, buy one now and be prepared for anything!

Quality, Portable Power!

[This review was collected as part of a promotion.] This thing is a beast- in the best way! Its quality and I love the rugged wheels it comes with making it portable. The best feature is the tri fuel. It’s great to have multiple options to power it. Worst part is how heavy it is and trying to get the wheels attached.

Generator

[This review was collected as part of a promotion.] I'm super happy with this generator. It's very easy portability wise to move around if needed as it's on wheels. Maintenance is easy, so that's a plus. When the power goes out, this will help light up the whole house. Noise level is hardly none.

Seems well built

Purchased it for piece of mind. I have only ran for about 6 hours so far and that was for the break in and multiple oil changes. One of those hours I did have it hooked up to my house and it powered everything I wanted with extra watts to spare ( that's why I bought a bigger one I read you only want to use about 60 % all the time to last longer) seems well made . only complaint it does use more gas per hour than other comparable models but that's it
