Would RecommendI purchased this unit in a pinch due to a severe snow storm. This unit was able to run almost the entire house, including the well, hot water heater all lights,fridge, and sump pump, along with a few other odds and ends without a problem The unit is loud, like most generators of this size, but it is expected. The single dial made it easy for my wife to start while I was at work. Fuel consumption was all dependent on how many things were being powered up and seemed efficient. I ran the unit appro...

New But Like So Far
Would RecommendJust recently purchased. So far so good. Easy to assemble. Bought for sump pump back up but can run sump, refrigerator, furnace blower, two rooms and a TV simultaneously with no problem. Can be bit noisy but if you keep it recommended distance from the house you will be fine. Only additional feature I would like to have is electric start but not many generators at this price point and wattage offer them. Live in cold weather climate (average temperature this time of year is low 30's) no pr...

Seems like a good generator
Would RecommendI just bought this generator today so I don’t know how this will perform over the long term but for now it seems like a good generator. I like the Rapid Start dial. It’s very easy to start and stop without having to find a bunch of different switches and knobs. It started on the 3rd pull after setting it up for the very first time. Assembly was pretty easy but the generator is very heavy so you may want someone to give you a hand. It’s not as noisy as I expected it to be, to be honest. My old Su...
Worth it
Would RecommendHands down best generator for the price little loud but ran 12 hrs at 3/4 load on 1 tank of gas

5 years and it’s still rated #1
Would RecommendBought this exact model 5 years ago. I looked into generators before parting with a pile of cash. Every where I looked this Generic 5500 was the best rated and also Consumer Reports not only rated #1 over 5 years ago, it also rated it #1 in last months Consumer Reports. Be smart and buy this model. You will love it. Be well
Deceptive accessories
Would RecommendThe box says that it comes with what looks like a 30 amp cable that hooks up to a house. This picture looks nothing like the extension cord it really comes with that has 4-20 amp 110 connections. Lowes does not sell the 30amp-30amp connector cable either, but they do have the parts to make one that total about $90 depending on the length of cable you get. If you do decide to make one, remember that the picture IS WRONG... The cable need a male and female connector, not 2 males as depicted o...
hard starting
Would Not RecommendIn cold weather the only way it will start is with a spray of starting fluid into the carburetor..

hard starting
Would Not RecommendOnly 2 years old 6 hours run time. Will not start in cold weather without starting fluid. With a spray of starting fluid starts on first pull.
Dependable and Easy to use generator
Would RecommendCranks easily and runs smoothly. Reliable power source.
Great powerplant but poor fuel cell
Would RecommendI've really enjoyed using this generator when its working. However, rust has developed in the gas tank and it has been nearly impossible to remove. Replacement units are all over $100. Maybe a plastic fuel tank would have been a better solution??

Just what I needed after Irma
Would RecommendEasy to assemble and started on second pull. Voltage was 122 and ran great for the 30 hrs that I needed it .

Impressive 5500 Generac "Rapid Start"
Fully agree with the "Rapid Start" title. Assembled the unit, serviced it as per owners manual, and one pull, it stared right up! AMAZING! Very impressed. This unit replaced a 5,000 watt Generac unit that I purchased in 1999. (The 10 HP Briggs unit "gave it up" even after making sure it was properly serviced every six months.) Very impressed with the metal tank with a fuel gage. Nice little option. Ran it for about 10 minutes, loaded it up to make sure it was reliable. Done deal. Very...
