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 Helped out in an emergency My old generator died during a power outage that went on for 4 days. I found this unit 40 miles away and the price was less than the larger stores. It was easy to assemble and started on the first pull. It powered everything I NEEDED and never failed.

Rated 4 out of 5 by from Broken handle bracket The handle bracket broke on my Generac GP5500 generator, its a welded bracket, my friends and I removed the broken part and used the remaining bracket and handle, and bolted it up, its more sturdy and looks better, I have pictures , but couldn't uploaded them, let me know if you want to see them, I know it will improve the handling of the generator, do we get at least a ball cap for this? Its me and my 3 friends that came up with this idea, we are glad to have improved your product, thanks
