Very Good So Far

I bought the Generac GP6500E because of an extended power outage last Christmas. We recently had a Fall snow storm and were out of power for 4 days. The generator performed very well during the outage. Started on 1st or second pull every time. Provided all the power I needed to run the well, furnace, lights, TV, satellite dish, Fridge and freezer. It would run longer than the 10 hours the specs say at half load. Only issue is that it is a little bulky to move around if you are not on pavement. It is a good sized machine so it sinks in a bit on grass, especially if it is wet. The wheels are good sized and the frame is sturdy but it is heavy enough to make it a little difficult on grass, sand. The wheels also pack up with snow and stop rolling so you need to keep the path clear to the ground or clear the wheels frequently. Other than that it has been a good machine.

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.

No Doubts, money well invested

I am very satisfied with my purchase of my GP6500E generator. It was money well invested. The quality and performance of this Generac generator is great. The installation and startup directions were very easy to follow for someone like me that is not to keen on the mechanics of putting something together. The motor is not too noisy at all, we can barely hear that our generator is on at all when working. I will definitely recommend this product to all my family. I am getting ready to purchase a Generac Home Standby Generator in the next few months.

Great for emergency power

I am a 65 yo woman who needed son to do initial set up before Hurricane Irene. After that I was able to service my generator myself. It ran window air conditioner, tv, computer and refrigerator and some lights, I am very pleased and recommend this product.

Bigger than advertised

Great generator and I've owned several over years. Very much leaning toward it being much stronger than 6500 it's more like an 8500.... Also idk what they're talking about 10.5hrs on a tank I powered my home 19.5hrs on same tank of gas during a several days outage.

It has what the average household needs.

Only time will tell if it holds up well over the long haul, or if the investment was a poor decision. Realistically I don't believe it is meant for heavy duty service, but if taken good care of, and with only emergency duty, I will expect a long service life (many years) of reliable service.

Great unit

I live in an area that is rural and the power goes out a few times a year. A month ago we had a storm and lost power for about 24 hours. I had a little generator but it was only good for a couple lights and t.v.. Problem is I have a refrigerator, a freezer, and a well pump I need power to as well. Next week I went looking for a bigger more reliable generator and found it with my generac 6500. After I got it home I was actually hoping to have another storm knock the power out so I could see how it would do. Wasnt long and it happened! It was only about a week later another storm came through and knocked the power out for about 7 hours. Long enough to try out the new generac. Rolled it out easy enough even though it's pretty heavy, pulled once and it was running like a champ. Plugged in the necessities and it handled everything. It was so nice to have in that situation. This winter I plan on having a transfer switch so I can run everything from lights to heat. I'd recommend this generator if your looking for one.

Excellent Generator

The power to my house has been pretty reliable up until this year. We have has three outages for extended periods of time so far this year. I have a well and a freezer full of beef, so I bought this generator to power my house during these outages. The power has not gone out since I bought it, but it does run all my appliances and the well pump without any problems when I tested it. It is worth having the insurance of stand-by power when it is needed.

Everything you will need

I bought this in the fall of 2012 after Katrina ripped through the Northeast. Our area was ten days without power being restored. We suffered through three days without power before getting this. Our home water supply comes from a well. No power, no water. Or heat, or showers, or communications. This unit has enough power to run the well, satellite, refrigerators, freezers, lights, coffee pot, microwave, televisions, and the list goes on. I just pulled it outside and started it up again for the second time this year. It powered up on the second pull and was running strong. I never worry about losing power now. Get the biggest one you can afford, but the 6500 will get you through any power outage with minimal disruption to your life. No regrets on this purchase. Quality machine.

Plenty of power and love the electric start.

Very easy to setup, had the house on backup within minutes of receiving the unit and it runs everything we need with power to spare. 10 circuits including fridge/freezer. well pump, boiler, lights, , microwave, kettle, toaster, home theater and office...!
