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 Great running product This product always starts on the first pull. Ran two refrigerators and the tv and a game system for my kids. Great product. The handle folds easy with a push button unlike other brands where you have to dissemble for storage.

Rated 5 out of 5 by from Runs like a champ Bought the 5500 during a major northeast ice storm. Power was out for close to 5 days, and I was desperate. Started right up nicely, and used it to power the fridge, chest freezer, bullet heater, and some essential lights. Gasoline generally lasted around 12-14 hours per 5 gallon tank. No issues whatsoever, and I'm happy with my purchase.

Rated 1 out of 5 by from Very poor carburetor design/manufacturing, broken plastic choke butterfly valve pivot pin. Planned to test the generator in preparation for the potential hurricane. Very poor carburetor design/manufacturing, broken plastic choke butterfly valve pivot pin, plastic choke lever. Very disappointing customer service, no support. Less than 10 hours on a 3 year old, perfectly maintained GP5500, flipped choke lever to start the unit and the plastic butterfly valve pivot pin/connector snapped. GENERAC only sells the entire $75 carburetor assembly, not the 25 cent plastic part. The generator was typically very difficult to start and particularly noisy when it was functional.

Rated 4 out of 5 by from Reliable Product Easy to assemble and activate. Has a nice handle to move generator around. Great standby generator.  It is powerful enough to keep home essentials running smoothly in the event of an emergency or a power outage.
