Tje product will will my needs if there is a storm like sandy again

Last year after storm Sand we were without power for 13 days. I don't ever want to be in a situation like that again, Cold showers and food wasted. I had an old Volt generator that would only run 90 minuets on a fuel refill. then had to wait for it to cool down to start over again, The features of the Generac generator I purchased will run 10 hours and has an battery start. Being 73 years old that is a life saver , i should have done this sooner . I need this for the next storm. Love the product

Simple set up and easy operation.

We purchased this unit as a home back up power source to insure our furnace and well pump were operational during winter storms. I found this unit to be an easy set up for that purpose, and a whole lot more. Although the weather has been cooperative this winter so far, I've found the portability of this unit to be valuable in powering all sorts of tools and lights in my newly built pole building. I recommend this unit to anyone needing a standby power source. It's great!

Paid for Itself

During the recent late October heavy snow fall and subsequent weeklong power outage our generator easily powered two deep freezers, refrigerator, and oil fired furnace. This allowed us to stay warm and fed in our home. The generator started everytime without fail and with little effort. We are in the process of installing a transfer switch for future ease of use. We strongly recommend this high quality generator for use as a home backup power supply.

Awesome product

[This review was collected as part of a promotion.] I’ve been wanting one of these for awhile now! Living in Ohio and having your electric go out during the winter is horrible! Now if it goes out I am able to keep my kiddos warm! I highly recommend this! I used it on my friends RV over the weekend and it works amazing! Love it.

Fulfilled all expectations, reliable and convenient.

We live in an area that seems to lose power frequently. The convenience of the battery start was a very compelling feature (it replaced a pull start - I'm 77 and it started to be a challenge) It was such a great experience, I purchased one for my grandson in New Hampshire. Strongly suggest installing an input receptacle connected to your home distribution panel.

This product works great!

My company purchased this generator at the recommendation of our electrician. We have a 20,000 sq ft facility (5k office, 15k warehouse). We looked into a 45-60kw standby generator but felt the cost was too high. We decided to try this unit with a manual transfer switch for our facility. One week after installation we lost power for 2 business days. This generator ran 2 HVAC office units, 6 modine gas heaters, 25 personal computers, 3 computer servers and related hardware, office telephone, fridge, half of the office and warehouse lights and more. If we could have hooked up the transfer switch to more of the breakers I think this unit would have powered almost the entire facility. It started and ran without skipping a beat. We spent a fraction of the price quoted for a built in standby unit. We would recommend this setup to any small business.

Steady, Reliable, Ready

At 68 years old it was just getting too much for the wife and me to pull-start that old 5k "Powerbase" predecessor anymore, particularly on a cold, snowy day. We moved into a new(er) house this Summer, and decided to upgrade the generator as well. After a ton of research, I settled on the Generac GP8000e, and I have not been disappointed. Last week the power was down Tue, Wed, Thur, and Friday due to a nasty storm. The GP8000e ran day & night for four days without missing a beat. On Saturday, with power retored, we agreed that that beauty had definitely paid for itself. ( We have 2 freezers, the fridge, and it ran our deep well pump as well, so we had water for showers & flushing, besides all our lights and TV. We were very comfortable throughout the storm, and my wife was able to refuel & restart the gen by herself in my absence, ( something she could have never done with the old 5,000. Then,just as we were patting ourselves on the back for the wisdom of our purchase, last night (Sunday) the power went out again, with "Estimate for Restoration: Unknown." To be perfectly honest, we don't care! We started the GP8000e and went to bed. ( It's just Not our Problem! ) I would like to add that: We checked the oil at every "Refuel" and it never used a drop. Actual "Runtime" unknown, we refueled every 12 hours. I definitely Recommend this unit for all of you. ( I made my son buy one for his house ) This is not a purchase, this is an "investment".

excelent portable generator.

Purchased this generator after Hurricane Michael. I used it to run refrigeration, medical equipment and my well. It had absolutely no problems carrying the load. It is a quiet generator and ran for about 14 hours on a tank of gas. I highly recommend this generator.

Works every time

This Generator starts every time and I have had no problems in 2 years. Shortly after I got this unit I had shoulder surgery. The design of the unit allowed me to set a couple short pieces of 2x4 on top to straddle the fuel line and set the 5 Gallon gas can right on top over the fill hole using only one arm. The only problem I had with this unit was when I let the oil level get too low and the unit would not start without enough oil....good safety catch! I put oil in it and off it went without a hitch. I ran a refrigerator, small freezer, sump pump, well pump, furnace, TV, garage door opener, and some lights with no problems. I have used it several times now when we loose power here in the country and it has never failed me.
