What Customers Are Saying
The generator provides ample power to run essential home appliances and electronics during power outages. It is easy to start, durable, and fuel-efficient, with a portable design that makes it easy to position as needed. However, some users found it to be quite loud, and the fuel gauge may discolor over time.

Would Not RecommendHad the unit for a couple years, and try to start it every couple weeks. After a while it started to give me trouble starting. I figured it was the fuel, so I purchased the TruFuel from Lowes (was told it would eliminate the stale fuel issues). Started right up with the TruFuel. Then about 4 weeks later I tried to start it, and it refused to start! Had to give up and put it away. Hope the power does not go out, because I cannot depend on this generator.
check the fuel hoses
Would RecommendIt's apparent that before generac let's the generators leave they test them out, which is a good thing. After testing them i am sure they then have to drain the oil and gas before shipping them. Now the only issue i had with this generator was after I refilled the oil i went to put gas in it (keep in mind i am doing this in the dark) afterppouring about 2 gallons of gas I realized something didn't seem right. That's when i discovered that the fuel hose was still disconnected and I had just poure...

Ran like a champ during Hurricane Matthew cleanup
Would RecommendWe got this generator a couple of days before Hurricane Matthew hit our area near Hilton Head Island, SC. After the storm, I set it up outside of our garage door alongside the house, gassed it up, and pulled the cord – and it started right up! I plugged in the big 220v power cord it came with, ran it through the garage and into the laundry room, then started plugging extension cords into the 4 outlets that had two separate 110v circuits. • One line went to the big refrigerator in the kitchen....
It sounds like you've put the unit to good use! We are thrilled to know it was there for you in your time of need. Thank you for providing us with yo...

Good for the money
Would RecommendOnly have about 14 hours on it so far, but it appears well built. Cranks easily and good output. Gas consumption is relatively low. Unit is loud, but most of this type are.
Must have
Would RecommendI've never owned my own generator. I bought this one in a pinch because of Hurricane Matthew after we lost power. It was the only ones Lowes had left. I got it home and took it out of the box and assembled it in about 20 minutes. I turned my main breaker off in the house. I took the cover off and made two plugs one for the left side of the breaker box and one for the right side of the breaker box. I then used the power cord given but split the load between the red and blue just as stated in the ...
Hurricane Proof
Would RecommendBought it three weeks before Hurricane Matthew. Set it up when I got home and it cranked on one pull. Had a transfer switch installed and it pulled everything in the house except for AC, Water Heater, Range and Dryer. Had no problem running my fridge, freezer, microwave, lights, TV, electric griddle, toaster oven and even more in a 4 bed house. We were without utility power for three days, and other than lack of hot water, we really couldn't tell. We were the only house with working exterior lig...

Poor Quality
Would Not RecommendI purchased my Generac Generator in February 2016 from the Lowes in Fort Myers, Florida. I was impressed with the initial set up and what appeared to be initial quality. The unit ran great but I noticed that I was using a lot of oil. I contacted Generac and was given the name of their local Authorized Warranty Repair center and delivered the unit to them. It seems that there was a defect in manufacturing and Generac decided to send a new motor instead of replacing the entire unit for me. I waite...
excellent generator
Would RecommendBought this on Tuesday because we were going to be hit by hurricane Matthew, fortunately only had to use it for a few hours. Assembly and preparation was easy, just followed the instructions. Test ran it Tuesday, started on the first pull tested it under load with some power tools worked great. The power went out Friday so I hooked it up, started again on the first pull, handled all the loads just fine. I could tell when the refrigerator would startup by the generator adjusting for it. Was ...

Can't go wrong with this unit
Would RecommendHurricane Matt left us w/o power, and it looks like it's going to be that way for a couple days at least. I unboxed it, assembled the few parts needed and had my lights on in less than 20 minutes. So now while my neighbors are stressed and doing without...I'm watching a movie, having a cold one and enjoying the night. No worries about food spoiling, or a freaked out wife! Generac pretty much invented these things for the general public...and I appreciate it.

Generac 5500
Would RecommendBought this with the possibility of the pending Hurricane Matthew. We had wanted to but one for some time but felt this was the best time. It was on sale for 10% off and I saved an additional 10% with my military ID. Put the wheel kit on and filled the oil and the gas and it started on the 3rd pull. Ran smooth and perfect. Plugged in a few items just to test and no problems what so ever. All items worked perfect. A peace of mind even if we don't need it for the hurricane. With winter on the way,...
Good quality generator with some irks
Would RecommendI have a champion 4000 peak watt genny that was left on my land when we bought it. Used it for about 4 years and then it kicked off and stopped working in the early morning in early august while it was in the 90s temps. After spending a few hours trying to get it going with limited tools(no AC for the wife and dogs) I gave up and dragged the wife off to find a new generator as we were already thinking of getting a stronger model anyways. This genny is good quality. Bought from lowes and the...
Great Generator
Would RecommendI took a long time reviewing different makes of Generators and after reading lots of reviews I went with the Generac Rapid Start 5500. With living in an area of the country where we get both Tropical storms and Ice storms we are and have had several power failures. So for comfort I bought this generator on sale. I picked it up at the store and it took me about 20 minutes to put the wheels and feet and handle on. Very easy !!! I then filled the tank with gas and stabilizer and it started on the f...
Nice piece of equipment
Would RecommendBought mine about 3 weeks ago now and have about 10 hours of run time. I'm using it mostly to power a deep well pump for intermittent use watering plants and washing digging and concrete tools. The item is very sturdily built. Assembly consists of putting on the wheels and handle. Mine started on the first half of the first pull! I added the gas and oil, pulled the cord about a foot to find the compression point and it started! It has started first pull every time and I only run it about 1...
Generac Rapid Start 5500
From what I read and how fast it started, it must be a Honda cloan engine. This generator runs very smooth and loaded with power. Used only twice, very happy with this unit. This is my third generator over the past 35 years. It is by far the quietist, my push mower makes more noise. For those who complain about the loud operating noise, must not own a push lawn mower! The power cord that comes with it is high quality and handy to have. I would recommend buying this unit.
Started up right away
Would RecommendWe purchased this unit directly off the shelf as there was a widespread electric outage in the area and this was the only generac left. We originally were looking for the 8000 watt unit. The 20' extension cord was not with the unit. Also, many of the parts were not properly or poorly installed (most washers were not installed or included with the paperwork ).The salesman in that department was very helpful. He knew the cord had been there earlier. Apparently, a customer wanted to 'borrow' the co...

I purchased this generator in Aug 2016 about 2 weeks later a tornado came thur the city of KOKOMO,IN All the power want out in the city,and the city was tore up thank God nobody was hurt, one pull the generator runs just fine I love it I would recommend, ran it for 24 hours with no problem
Easy to set-up, start and run
Would RecommendFirst impression: Just bought the 6672/5500W yesterday. It took a relaxed hour to read the manual, attach the wheels, legs, handle and put in the oil. I then put one pint of gas in the tank, turned the super simple control dial to #1 (start) and gave it one medium-strength pull. It started instantly. Then, turning the dial to #2 (to run) tested a load on each of the outlets and on the 20' twist lock-to-4 plug extension cord that comes with it. All worked. The pint of gas lasted 11 minutes. It it...

Awesome through and through
Would RecommendThe most reliable generator I've ever had. Starts right away with one turn of a dial and a simple pull of the rope. I literally put fuel in this bad boy and pulled the pull start and it exploded to life. It has more than enough power for what i needed and it just keeps on running until i simply turn off the dial. I recommend this to everyone in need of some serious power.
