Rated 5 out of 5 by from Great value for the money During the Sandy storm we used our GP5500 to run a portable heater, 2 refrigerators a few lights, TV and cable box and an occasional hair dryer. We did have to alternate some of the appliances so that we did not overload the unit.We used a 30 amp cable with 4 outlets bought separately to run 4 appliances leaving the other GP5500 outlets unused. Overall we are very happy with the generator. We really used it for only the essentials and to keep informed on what was going on elsewhere in the northeast. I would suggest the 30 amp manual transfer switch kit to avoid the extension cords, that is my next investment!

Rated 5 out of 5 by from Perfect for home use. Very easy to use. The 5500 is compact and has plenty of power. Backup my house during Sandy for 7 days. 5 gallons of gas for 10 hours , 2 fridges , heating system, water heater, electric kettle and light.

Rated 5 out of 5 by from Great value for what you get. This is the 1st I've owned. Sandy motivated the purchase. Had to go on a waiting list and Lowes came through on Sunday before. Wired it into the panel. Set-up was easy. It started right up. Had to use it for 24 hours after Sandy and 24 hours after the nor'easter (Andrea?). Powered the whole house with no problems. This generator has provided a long awaited peace of mind.

Rated 5 out of 5 by from Fantastic unit, Bought this days after hurricane Irene, didn't start it until the night of hurricane Sandy. Started right away after carb was primed. Was the envy of the neighborhood because I had prewired the house with a manual transfer switch so this generator became plug and play basically running my entire house. Can prob run a few window a/c units for summer outages if necessary. Worked well with very little effort.

Rated 5 out of 5 by from So far so good I unpackaged the unit. Assembled it, with relative ease, in spite of cryptic instructions. Put in oil, gassed up and it cranked perfectly. Easy to pull. Ran long enough to make sure output was working and shut down. Ready for SC hurricane season.

Rated 5 out of 5 by from My neighbours went out and purchased their own after watching mine started up so easily and had the power that I needed. I was so excited that the generator was on wheels and had a handle that easily controlled with ease moving the generator where I wanted to take to. The outlets were an excellent design in this generator with the capability to run separate voltages. One of my neighbor who is a contractor told me that that I made an excellent choice in the purchase of this generator. I will recommend this generator as an excellent choice above any generator that I had prior to this one.

Rated 5 out of 5 by from Good unit and my allowed me to keep my house warm and my food stuffs cold! I purchased a portable generator due to a severe wind event on February 24, 2019 in south western Pa. The unit I purchased is not identified on your listings of various series of units. I called your customer service rep and she did a little research. Informed me I should pick the unit that most closely matches my unit. My model is a Honeywell-Generac Model: 0060372 Serial: 8023834A. a 5500 watt unit that has I used it for three days pretty much non-stop and it was totally dependable. I was surprised a little with the fuel consumption rate. I was only serving three devices. A refrigerator, a mid-sized chest freezer and my oil furnace burner with fan. Total running wattage demand 2475 watts excepting any periodic surge demand when a motor might start up. So the load on the unit was unlikely ever at peak output that could cause the fuel consumption ratio that I think I experienced. All in all, still a real good purchase and now I am ready for the next First Energy outage!

Rated 4 out of 5 by from The unit is good when it runs We bought the product during an extended power outage. It worked fine for the first 10 hours and then quit and wouldn't start. We learned from the hardware store where we purchased it that the engine can have problems running on gasoline purchased from a standard gasoline pump which may have up to 15% ethanol. Once we put in recreational gasoline without ethanol it ran fine.
