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 4 out of 5 by from Hurricane Irma Relief Great generator. I have been running this 24/7 for 6 days without incident. Running 2 portable AC units, 2 refigerators and all lights and fans. Also have run the washing machine and dishwasher but only with 1 AC unit.

Rated 5 out of 5 by from Great for every SFL home owner. I bought this generator prior to Hurricane Irma. It was easy to set up and use, specially since this is my first generator. It kept my refrigerator and my entire entertainment system running. As of now I am very happy with this investment. JR

Rated 5 out of 5 by from Easy to handle First time buyer of a generator. It was an emergency buy when we lost power during hurricane Irma. I must say I was impressed by the power it gives. Allowing us to keep the refrigerator running, light, 2 fans, TV, DVD player, charged cell phones. It packed a lot of power. A full tank gave us a least 12 hours running time, if not more. Highly recommend this product

Rated 5 out of 5 by from Available Just In time! Lost power during Irma and found the GP 5939 available while in search of batteries! We hooked a couple refrigerators and lights/fans until we regained power a week later! Easy to use and got the job done. Hopefully we won't need for Maria but if we do we are ready!
