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.

Service and Repair a Must

Purchased this Generac Generator, works great with RV, easy to move around. One thing all Generator owners NEED to remember is that if your Generator breaks down, Somebody has to Repair it. GENERAC Has Excellent Service and REPAIR. Generac is Nation Wide so finding repair service for Genrac is easy. Please Remember this folks. Service is Paramount. My Generac has Not needed repair and probably will Not . Thank You Generac

Powers almost whole house!

I researched a host of generators before deciding on the Generac GP6500. For me the Generac brand was the deciding factor and the GP6500 was the largest wattage I could fit into my budget. It was shipped promptly and arrived without so much as a scratch on the box. Assembly was quick and easy. Had a transfer switch(6 breaker) installed and everything in the house is usable except central air and washer and dryer. The generator started up on second pull and roared like a lion but powered everything I wanted it to power with room for more. I couldn't be happier. Almost looking forward to the next power outtage because I am ready for it now. I have not seen anything on this generator that is not well built and ready to last for a long time.

Poor Quality, not recommended

Very poor. Bought GP6500 just after Helene last year. Took 2 days and a lot of energy (it gave me a good workout pulling the starter) to get it to start. I tried leaving a review then at Generac's website using the link they provided, that didn't work either. I bought another generator, better quality, different brand, for reliability.

Quality machine

After a 3 day outage this summer, I upgraded from a 5000 watt generator to the 6500 watt Generac and installed a larger transfer switch so I could power more items during our frequent power outages. The machine is obviously well built. It has a small footprint and it's easy to move and started on the first pull. Based on other reviews I thought it might be a little noisy. But it actually seems quieter than my old one.

Just what i expected!

I always do a major investigation before i purchase anything expensive.Sometimes it takes me weeks.I read everything including reviews.Finally after days of asking questions and reading many reviews i felt the Genarac GP6500 was right for me.I was right.Assembly was easy and took about 15 mins.Filled it with the oil that was provided and it started in two pulls.The unit was powerful enough to power up my whole house except the clothes dryer and electric oven.No more freezing in the winter or sitting in the dark.It is relativley quit and ran about 10 hrs on a tank of gas.I am very satisfied with my purchase and you can't beat the quality of Genarac.

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.

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.

Great and reliable product to purchase.

2 of my friends, my sister and I brought the GP6500 Generator 2 days after Hurricane Helene hit our hometown in Georgia September 2024. I assisted 1 of my friend with the assembly process and I assembled both mine and my sister's generator by myself. It was a simple process. Once gas was added to the fuel tank, all of them cranked up on the first pull and stayed running until they either ran out of gas or was turned off manually. The generators was a life saver. They supplied power to what we needed and never failed to perform perfectly. They were used for 6 days before the utility company was able to provide us electricity again. I am now in the process of trying to get a manual transfer switch and power inlet box installed so that I can be more prepared for the next power outage. Thanks Generac.

Poor Quality

I was really surprised at the poor quality of the generator I purchased in the aftermath of Hurricane Helene. The fuel tank leaked fuel. Once I got the tank replaced, the fuel petcock now leaks fuel. Even the replacement one I received leaks fuel. I would not purchase again, nor would I recommend purchase of a generac generator.
