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.

Great Features

Good value for the money. Will take stress away from power outages. Protect my home from water freezing in pipes and damages thereafter during winter months. Comfort for family during outages. Can't rely on Power Company to get power back in reasonable timeframe, less than one day. Have had outages lasting 1 - 3 days. Power Company continues to get worse every year due to their lack of maintenance, outage prevention, manpower reduction.

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.

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.

Runs when you need it!!

Bought this to replace an older one I gave to my son, ran like a champ for years. The new one was purchased because of the Deracho that went through our area Benton Co. Iowa, August 10, 2020. Finally found one 75 miles away in Cedar Falls. First oil change 41hrs, second change at 109 hrs. The unit ran continuous for 187 hrs. straight! One pull start every time. The unit ran our 28,00 sq. ft. home, AC, frig, freezer, lights etc. Excellent piece of equipment and reliable! Never been happier. Thanks, Lee

This product was well worth the money.

I bought this generator after Hurricane Irene and I had to put it in service during the freak October snowstorm that hit the East Coast. It performed as well as expected. I used it for 36 hours without a hitch. My wife was happy to have hot water to take a shower and also she enjoyed being able to use the microwave. I argued with her for 14 years as to the pros of having a generator. She always said it would be a waste of money, guess what ? Her tune changed during the snowstorm. She was happy to have the generator.

The Little Generator that Could

During Hurricane Sandy we were without Power for 13 days. My friend got power back in five days so he lent me his Generac GP 6500 and it powered my four bedroom house for 8 days without a problem running about 20 hours a day. So I went out and bought one for myself. My neighbors with bigger generators were very impressed with my little generator that could.

Best purchase EVER! GREAT!

I just bought this generator the day before this huge blizzard we lost power and this thing ran like a champ! Extremely easy set up, put the oil in it and gas in it like they said one pull and this thing fired right up. This generator literally ran our entire house no problems! So if you're looking for a reliable well priced good little portable generator, this is the one you want!

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...!

Very happy with product

Generator arrived very well packed. Initial setup was easy. Fired it up and put it on line with no problems. Very happy with product and feel I got a "good deal". If I were to make the product better I would give it a built in battery charger. The accessory style unit is okay, but is slightly inconvienient.
