Customer Reviews
Rated 5 out of 5 by from Well made and plenty of power. Started right up and ran without any hestitation. Connected several items including a 240v heater and 14 amp electric saw at same time and no problems. The only thing I wished to be included is the wiring diagram for the 240v outlet. Had to go online and dowload spec sheet to get it. Anyone not an electrician might have trouble converting a 4 wire plug to a 3 wire outlet.

Rated 5 out of 5 by from Perfectly fits my needs! We're in the middle of a power outage caused by a severe line of storms. I went out and bought this generator without doing any research whatsoever -- I just needed a generator! It hasn't let me down. I'm currently powering my fridge (and the neighbor's fridge & freezers), my computer/router/modem, lights, and various other small appliances with no issues at all. In fact I'm currently typing this review on my computer that's on generator power. Wish it had a wattage gauge and an estimated time to empty fuel on it but those are minor details.

Rated 5 out of 5 by from Sweet unit for Power The GP5500 is a replacement for an older Generator we have had for many years. This new generator is compact, reliable and functionally better than other 5000-6500W competitors. Easy of use with the attached handle is great. We use this for outdoor power in the woods and also as a backup when the weather turns. Reasonably quiet and full of juice to keep the group happy from lights to tools. Great Purchase.

Rated 5 out of 5 by from Excellent ! I researched units for two weeks and this unit was best for the money! I have a food truck business in North Dakota's oil boom and needed reliable emergency backup power for outages! It runs my entire business with room to spare " that was the intention". Put the unit together and it started on the first pull! Good looking machine and is a power house too! Thank you generac!

Rated 5 out of 5 by from This generator works good. We bought the GP5500 to use for my camper. It was so easy to set up and use. It was a perfect size and powered everything we used. However the wife and I had a problem lifting it on the back of the truck. A little heavy for us old farts. But other than that we were very happy with it's performance. I would recommend this product for those who have a camper. We also plan on using it as a back up when our electric goes out at home.

Rated 5 out of 5 by from Excellent generator for the price I work on utility sized generators. Generac is one of the best. I purchased this one for backing up my home during outages, and may use it for other projects or outings. The generator was simple to set up and assemble. I recommend using lock nuts or thread lock on the bolts, since they tend to vibrate loose as stated in other reviews. Put oil and gas in and the unit started first pull. The unit is noisy, but quieter than the gas drive welder that I have used in the past. Tested it with a Shop Vac and it worked perfectly. One note, I have always been taught to close the fuel valve and allow the engine to run out of fuel, this keeps the carburetor from gumming up. I have never had to rebuild a carburetor on any of the small engines I have owned.

Rated 4 out of 5 by from When you need power most of us do not start and run our portable generator every week, so it may sit for several months between starts. But you want to know that wne you need it, it is there and capable. Our GP5500 sat for several months, and then I needed to use it and I pulled all the stuff off that was stored on top, pulled it out of the shed, checked the oil and fuel, turned on the fuel, ignition and closed the choke. I pulled the handle and on the very first easy pull, my generac started up. What more could you want from a generator.

Rated 4 out of 5 by from Not for continous use. But good for occasional use We used our generator on occasion during power outages, or just when we needed portable power. We had no issues until we hooked it up to a 240 volt pump and used it continually for a couple weeks. It lost all power to the plugs, and it is still in the shop getting repaired. But i would recommend it to the weekend warior who just needs a occasional power boost.

Rated 5 out of 5 by from Serves its purpose Wanted a generator to supply power to my home during storm and power out conditions. Has been a blessing in disguise and ready for the calling...
Date published: 2014-09-01
Rated 4 out of 5 by from A bit noisy We bought this for an upcoming storm. We did indeed need it. I used it for two refridgerators, microwave, furnace and a space heater. Definitely held up. I read the spec sheet to not overload it and came close but it held up for sure. A bit on the noisy end. My neighbor can hear it two houses down. It did it's job and that's all I was concerned with.

Rated 5 out of 5 by from It starts right up on the first cord pull. This generator has been dependable from the start. It's there when needed without a having a sore arm trying to get it started, It starts instantly. Best of all the GP5500 has all the power needed to run most of a house which is important to me, if a hurricane hit Florida, where I do live.

Rated 3 out of 5 by from Still trying this product haven't had it long enough to know for sure/ very easy to start. not sure we had trouble getting it to charge our trailer. It's in the shop now. Your telephone opperators are very kind and helpful.

Rated 5 out of 5 by from Well worth the money spent for great features. This model is outstanding for the homeowner who needs power. Living in the Northeast we experience power outages too frequently. This Generac model provides all that I need to power my furnace, refrigerator, lights, etc. Well worth the money spent for the peace of mind of knowing that Generac is an outstanding generator, with a reputable history. I would recommend this generator to everyone.

Rated 5 out of 5 by from This product is dependable in an emergency. Easy starting, quick installation, runs necessities in house.

Rated 4 out of 5 by from Just what I needed I bought this because our power was out for a few days. I ended up running it almost another 2 days straight to power our refridgerator, freezer, tv, some lights, etc and probably could have plugged in more things. I heard great things about the Generac name and their generators will not disappoint. This model has a fuel gauge, an hour meter (which is helpful in keeping track of when to do maintenance items), and it is easy to drain the fuel from the tank for when the generator is not being used. Overall, great value for the money.

Rated 5 out of 5 by from Ease of use I could not believe how easy it was to set up and run. I am 66 years old and had no problem (except getting the wheels on) getting it up-and-running. Ran 2 freezers, one refrigerator, and my neighbors refrigerator. I am now looking into getting the plug by my fuse panel to run the house since I have a well. If I can do it anyone can! Thanks for a great product.

Rated 5 out of 5 by from Every woman should own one, it starts right up! The price seemed right, generac has a good reputation. I decided that the 5500 would be fine for what we needed. Easy to put together, started up on the first try. So far great product.

Rated 5 out of 5 by from Great Product For functionality and value, you won't find a better unit than the GP5500. Easy to assemble, use, and maintain. Highly recommended for powering the household essentials.

Rated 5 out of 5 by from Great price. Well known product. I purchased this product because of the name [GENERAC] and the price was right.

Rated 5 out of 5 by from This generator is great! The generator is easy to assemble and starts easy. Easy to reach all the components that require annual maintenance. It will power a couple of fridges and allows us to run other household items we need to weather a long term power outage. We purchased this after moving to the coast and surviving a couple of long term outages before. Make sure you have a power plan for your appliances so you don't overload and always keep some load on it while it is running. When doing maintenance make sure you know where to dispose of your petrolem waste. Easy to change the oil and air filters.

Rated 4 out of 5 by from good buy for the price Good overall generator. A little on the loud side compared to other generators of the same size. Powers my camper with no problems once I got the 30 amp 4 prong adapter. My only complaint is with the pull start assembly. Already needs replaced. The plastic center spring housing has broken. It was not abused or treated roughly. Pull start hung up one time, took apart to see what the problem was and discovered black plastic pieces broken and falling out of pull start assembly. Once I replace that I'll be a happy camper again.

Rated 3 out of 5 by from 18 hours on our GP5500 We've had the gen unit for 2 years and only needed it on one other power outage in 2013. The unit has only been started 5 times. The starter recoil has jammed up inside the cooling fan assembly, I took it apart and the 2 metal centrifugal dogs were missing or should I say laying in the bottom of the cooling shroud. The plastic part that holds the pull rope was broke into numerous pieces. Being a midnight emergency for a continuous water supply for our farm animals I had taken a 1" nylon rachet strap and wrapped it around the small cylinder that the recoil usually engages and was able to pull start the gen unit. Looks like the recoil assembly needs to go back to the drawing board.
