Customer Reviews

Rated 4.7 out of 5 by 502reviewers.
Rated 5 out of 5 by Customer Great product, starts easy and very easy to move around, also good on gas. June 28, 2016
Rated 5 out of 5 by Works great for house power Bought this generator after last hurricane. Since then, I only had to use it once during a snow storm. Started on first pull and ran for hours without any problem. Overall a great product. April 7, 2016
Rated 2 out of 5 by purchased in the aftermath of super storm sandy. Went to fire it up yesterday (2/29/16), have no voltage output and it leaked gas from the carburetor. Replaced the voltage regulator and carburetor. Engine runs fine, still no voltage. Local dealer says I will need to replace the alternator, at a cost of over 300$. March 1, 2016
Rated 5 out of 5 by Excellent, so far. Fortunately, we haven't had a power outage since I bought the 5500 -- Murphy's law in reverse. But unpacking, assembly and startup were simple and straightforward to understand. With the conversational directions and easy pull start, I made sure my wife could start and use it if I was away. Success. If and when we have to put it through its paces, I'll write another review. February 23, 2016
Rated 4 out of 5 by Good Solid Machine My experience with the GP5500 has be very favorable. If there was an option to give the machine a 4.5 star rating, that is what I would have rated it. Because there wasn't that option, I rated it 4 stars.I bought this generator to power essential services at my elderly mother's home in the aftermath of Superstorm Sandy. It performed very well in the nine days that she was without power and allowed my bedridden mother to stay in her home as she wished. I would not hesitate to by this machine again. Since Sandy, we have had a few occasions to use the machine for much shorter periods of time. It has always started with relative ease.The only criticism I have of the unit is that it is very noisy. Obviously, quiet operation is not the primary concern during an emergency situation. But it is worth noting in that multi-day operation of the unit does impose the burden of having to deal with the noise. I've purchased an extra long cable that allows us to get the machine further away from the house. January 21, 2016
Rated 5 out of 5 by Exceptional value for the price ! The features of this generator and the cost exceed my expectations. it will handle any of my power needs during our twice a year blackouts in my area. December 22, 2015
Rated 4 out of 5 by GP5500 = One tough genny. The storm:The derecho of 2015 hit southern N.J. hard and fast leaving our part of Gloucester county without power for more than a week.The high winds knocked down many large, mature trees taking out the power of nearly our entire town.Our neighborhood was without power for eight days total, one of the last to have power restored.After locating one of the last generators within 100 miles I was pleased it was of a brand I had heard of .I worried it would be under-powered but that turned out not to be the case.Up and running:I used this genny to power my large kitchen refrigerator (new), ancient chest freezer, hot water heater/ furnace (oil/hydronic) lights, TV and computer. The GP5500 ran without a stutter for eight days. I changed the oil once and refilled it when the fuel level dropped to 1/4 tank. It easily ran all night on a full tank with these loads.Preparation and use:Refueling took about 10 to 15 minutes with 5 gallon gas cans and oil changes about the same. It takes about a quart of oil.The generator is easy to move around and wheels easily over the small bumps present in my yard. It was fully assembled when I picked it up from the hardware store. After a quick read of the well written instructions, I filled the crankcase and fuel tank. Turn a switch, fuel line open...It started on the first pull.I used extension cords run to my appliances during the storms aftermath and have since added a manual transfer switch to my electrical service. It now runs all the previous loads and six ceiling fans easily.Overall impression:This generator will serve emergency power needs for my 4 bedroom N.E. colonial home nicely. It seemed to be on the loud side at first but other portable generators in the neighborhood were audible over it. Re-fueling with gasoline can be a bit of a chore but for the storms I anticipate and the competitive price of the unit something I will deal with gladly.It is finished nicely with thick paint and seems well made. If you do not mind schlepping gasoline around and the minor mess it entails this is a good emergency power source. December 17, 2015
Rated 4 out of 5 by Easy to operate, start, and maintain I began my research for a portable generator that I could use at home to power several of the essential appliances in a power outage. I also wanted a generator that could used to power my travel trailer for long camping trips.After observing and testing other generators, I decided on the Generac because of price, ease of operation, portability, and reputation.The Generac 5500 watt generator easily filled the bill for both of the home and recreation requirements. It is simple to operate, easy to start, and maintain. I would highly recommend it for work, home, and recreation activities. December 14, 2015
