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 From small to very large - Generac generators are great quality I work for a general contractor and our company has used Generac portable generators for temporary power needs. I am also familiar with the large generators built for a large hotel or a hospital. I had never owned a generator but during hurricane Irma we needed a generator because of a medical condition my wife has. We only used the generator for 3 days until the power came back on. Now I own one for future needs.

Rated 5 out of 5 by from Excellent for limited back up power This unit was purchased to provide power for our 3 freezers, fridge, t.v., cpap machine, and limited lighting. We lost power during Hurricane Irma and this generator served its purpose well and did so very economically. Noise level was low as advertised. We learned our lesson during Hurricane Matthew as we were not prepared. Our intent is to purchase a standby unit with ATS for the entire house. The 5500 will serve us well until then.

Rated 5 out of 5 by from Just in time I purchased this just before Irma hit us. Easy assembly for the wheel kit. So happy it came with the wheel kit making moving this unit around very easy. This unit fired right up and gave us the power we needed for 8 days till the electrical lines to our house were repaired.
