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.

Quality Generator!

[This review was collected as part of a promotion.] This is a good powerful Generator. It will keep my furnace, refrigerator, and freezer working during a power outage. The instructions to assemble the Generator could have been better. It took a little time to assemble it. Overall a really quality Generator.

Great emergency power for necessities

I've been very happy with this generator. I set it up as soon as I brought it home because I wanted to ensure it didn't have any issues. It started right up and produced power. I drained the fuel and put it in the garage. I use the generator box as a cover so other than a few disrespectful spiders it looks brand new. I've only had to use it twice in the two years I've owned it and both times it fired right up, as soon as I remembered to turn the power switch on. We used it to power the refrigerator, tv, satellite receiver, and a light. As expected, it had no problem powering those. As for the sound, I don't really consider it quiet. I put it about 20 ft from the house under a shelter, ran extension cables through the window, put a towel in the window to seal out airflow and some noise. We can easily hear it in the house even over the tv at normal levels. I wouldn't consider it loud but it's much louder than the small generators I've seen used for tailgating. I'm not trying to compare the two. I'm just trying to give you a frame of reference. It wouldn't keep me from buying another one if I needed it. I don't know the limits of this generator but if you want to have power available for the basics when there's an outage, I believe this will work for most people.

Leaking Gas - Brand New!

Selected the GP7500E above two other choices. Assembly was easy but, I was filling up the gas tank and the gas was leaking out the carb almost as fast as I was pouring it into the tank. Called customer service and found out this is a know problem! Now, instead of taking it to our cabin this weekend, I am taking it to a Generac Service Center. Very unhappy that it is leaking gas out the carb and it is a know problem! Maybe I will get a gift card for all my problems.......but......I don't think so!

Just what we needed for small home back up

This is just what we needed for a back up generator. We live in a very wooded rural area and power outages in the winter can be brutal when temps drop below minus 20. The GP6500 is perfect because it is portable and reliable. Now when we lose power during a winter storm we grab the generator out of the garage and plug it into the transfer switch and it keeps us and our house from freezing.

Very powerful!

[This review was collected as part of a promotion.] This generator was bought to power my house during a power outage. It is easy to set up. The directions are simple-you don't have to be a handyman in order to put it together. It comes with the first supply of oil. You just open it up and pour it in! I am extremely happy that it has a push start. I am a very small framed woman and I was afraid that in an emergency situation, I would not be able to start it on my own.(with a pull start) I was able to push a button and bam power! It is quite heavy, but it's not hard to wheel it where you want it to go...and with the never flat tires, you won't have to worry about getting it stuck with a punctured tire. This generator is very powerful. I was able to power our refrigerator, the neighbors refrigerator, two TVs, a deep freezer, a computer, two fans and lights. It's not as loud as I thought it would be. About as loud as a lawnmower. This thing ran for TWELVE STRAIGHT HOURS! That's impressive! Bottom line is... buy this Generac! Don't buy a knock-off brand to save a couple of dollars. It will not have all the features of this Generac. It will not be as durable or as reliable. You will not be able to power the amount of things this Generac does and it will not run as good or as long!

Good quality

This generator is amazingly easy to start. I put oil and gas in it and slowly pulled the cord to make sure the engine would turn over freely and it started right up. The only reason I did not give it five stars is because the gas fill cap is in the center of the tank. If it was located closer to the side it would be much easier to add fuel to the tank without spilling it.

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.

Easy out of the box assembly.

Easy out of the box assembly. Took about 20 minutes to assemble. Everything you need in the box except the gas. Filled with oil, charged the battery and started right up. Noise level is less than I had expected....that's a good thing. Looking forward to using the unit for home backup.

The generator performed great during Hurricane Sandy

I purchased this generator after the issues with Hurricane Irene. When this storm hit and we lost power, I simply brought out the generator, hit the switch and forgot about it. It performed great. I ran my boiler, refrigerator and a TV. I have and will continue to highly recommend this product.
