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 Just what we needed Bought this generator just before landfall of Hurricane Matthew. We were able to power both of our refrigerators and an upright freezer and chest freezer. We then switched over to our window AC unit and powered our microwave and two fans along with 2 lamps without a hiccup in power loss. It worked PERFECT! Very well pleased with this generator. In fact, it worked so well, I am considering having a transfer switch installed to hook directly into the generator just to keep from running drop cords throughout the house to the different items that need power.

Rated 5 out of 5 by from Works great for house power Bought this generator after last hurricane. Since then, I only had to use it once during a snow storm. Started on first pull and ran for hours without any problem. Overall a great product.

Rated 5 out of 5 by from Excellent, so far. Fortunately, we haven't had a power outage since I bought the 5500 -- Murphy's law in reverse. But unpacking, assembly and startup were simple and straightforward to understand. With the conversational directions and easy pull start, I made sure my wife could start and use it if I was away. Success. If and when we have to put it through its paces, I'll write another review.
