Excellent generator. First time owner, couldn’t have been easier!

[This review was collected as part of a promotion.] I haven’t used a modern generator before - last one we had was 25 years old, was noisy, shaky, and we’d wear ourselves out getting it to start. Oh, and then there was the exhaust, smoke and low current. Not anymore! This thing is a dream. Arrived well packaged and was a breeze to set up. Basically you attach the wheels, front rests and handle and it’s ready to go. Well you add oil (included, along with a handy funnel) From there, startup instructions are well documented in the book AND on the generator itself. I really appreciate that there are easy to follow graphical steps on the unit itself for starting and running the unit. A few quick pulls and it was purring like a kitten. I haven’t had a chance to put too much load on it, but so far it’s easily powered everything I’ve thrown at it! The unit is heavy, feels like everything is high quality, and I expect it to last a long time. Definitely recommend!

Works well, enough power for the whole house

Except for hurricane Sandy, over the last 30 + years we had never lost our power for more than a couple hours at a time. And even those weren’t frequent. Then this past summer we had a Nor’ Easter with 60-70 MPH winds that lasted for a full day. We lost our power and did not get it back for almost 8 days because of the extensive damage causing slow repairs. I did not want to go through that again especially in the winter when not having heat is a safety issue. Bought this generator because it had enough power to run the furnace or central air plus the the two refrigerators and freezer we have. Had an electrician do the wiring to do the whole and not run extension cords. Have used it once since I bought it when we lost our power during a snow storm with high winds. The electronic start worked great and we had power enough to run everything. for the six hours till power was restored. Found the generator easy to start and run. Is small enough to store pretty easily in my garage. On the minus side it would be nice if it was quieter. And this is knit picking but it’s not easy to register and the serial number is hard to find. Added gas stabilizer as there is a decent amount of gas left in the tank and I intend to run it once a month till the gas is used up. Overall I am very happy with the purchase and is well worth the price for the peace of mind and convenience for the infrequent times of power loss.

For 50 hours then nothing

Bought this unit to get us through the storm last year. It did it's job well for the first 50 hours, then it quite running. It won't start and run. Pretty sure it's the electronics, the CO2 sensor. Saw a U tube video of the exact model doing the exact thing. Bad unnecessary CO2 sensor. So it sits there broken waiting for me to find a shop, time, and help to load it.

Hihg quality, easy to set up and use, reliable performance. Great value.

The generator was easy to assemble and use with minimal effort. Instructions were concise and intuitive. All necessary parts were included. The generator started after a few revs of the starter and ran reliably over the next 1 1/2 weeks after Sandy hit. It is reasonably quiet for its rating. It was used to run a variety of household items through the house circuitry which included well pump, septic pump, 2 refrigerators, miscellaneous lighting, oil furnace with hot water baseboard heat, TV, computers and microwave. There were no issues with the performance. There were two less than excellent features: 1) the "snap in pin that supports the collapsible handle is not very sturdy and it will not support any significant pressure. It sheared partially off when someone leaned on it, when locked in the up position. 2) the oil dip stick is not clearly marked with "full" and "add" markings and the instructions are not very clear about the fill level. A picture would have helped.

Quiet running Generator

I'm very impressed with this generator. After going without power last year for 5 days after hurricane Irma, I decided we needed a generator. After looking for months as to which one I wanted, I decided on the GP6500. It has the power I need in an emergency situation and is very quite compared to others I have experience using. Fired right up on the first pull and my girlfriend can start it also should I be out of town and the power goes out for an extended time period. Good value for the price and I like the dependability and Generac reputation.

Can't wait for a power outage now!!

As a homeowner, I am thrilled to have the generac generator. It was really easy to set up and it starts so easily with the electric start. Having a quiet muffler was also important to me. It' a convenient size to store in my garage and pull outside as needed to use.

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.

A Beautiful Beast!!

Our generator was purchased in the event of a power outage. We have had our house wired to accept gen power by an electrician. Our electrician was SO impressed with our generator. He even mentioned it was robust enough to power our whole 2400 sq.ft. house, except for the AC. During our testing, the machine started up within 1 second, made less noise than we would have thought for its size and power. The controls are easy to use and understand (I am a novice at this) and maneuvering this beast was actually pleasant. Sturdy contruction and high quality gives you an excellent feeling that this can handle high demands. During our testing, it performed perfectly and did power the entire house with ease (45% total load with EVERY light, fan, appliance turned on). If I could give it 6stars, I would.

Outstanding Performance

I bought 3 years ago and used it this past 3 days straight with no issues. I ran 3 refrigerators, all the lights in the house, garage door openers, electric heater, coffee pot, and toaster over. Really impressed with the power output. Plus the tank is fairly big, and last a long time once topped off. Only con is that it is really loud.

Quality Is Number 1

I purchased the Generac GP8000E after doing alot of research with several other brands. I am not disappointed, from the moment I started to unpack the generator I noticed the quality of the packaging, which gave me confidence in the product right off the bat. The engineering made assembly very easy! You notice the quality in every part as you put this baby together. The quality shows that Generac and its associates genuinely care about the product they put out to the consumer.
