Asset That Everyone Should Have!

[This review was collected as part of a promotion.] This is an indispensible asset to our household. Southern CA can be very unpredictable and this is our safety net for our family. It is well made and easy to move with the wheels. So glad we own it!

Sandy and Generac - a good combination

Just made it through hurricane Sandy's blackout. This was the generators first extended test. Passed with flying colors. This is the 6500 Watt model, manual start. Started on the second pull (usually does). I Powered, using the 30amp outlet - 1 Refrig, 2 gas forced hot air heating units, 1 gas powered water heater, 2 bathrooms, kitchen lights, dinette lights family room outlets (charged a lot of cell phones), and used applicances through those outlets (toaster over, coffee maker, washer/dryer), and of course a radio, hall lights and a bedroom. Using the 20amp four outlets, powered three more refrig, including a couple from my neighbors house, and some additional lights. The generator took forever to use the gasoline in the tank. No lights flickered, appliances functioned proprely. At times I forgot I was on generator. Thank You Generac.

Great Generator, But

I bought this unit for backup power 9 months ago. I run it 30 minutes every month. The last time I started it, it leaked a gallon of gas around the generator. Had I not checked after 5 minutes running, I am sure my building and surrounding buildings would have gone up in a huge fire. Needless to say, I returned the unit for a refund. I can't recommend this without knowing what the problem with the generator is! Never, never, another gasoline generator.

Better then my first Generac

I already owned a 5kv Generac and was extremely happy with it. A few weeks ago my daughter lost power due to storms and was told it could be 5 days until power returned. I loaded my 5kw on trailer and connected to power her frig, furnace, and a few lights. Generator worked great as always, and saved all food, kept house heated. I then decided why haul back and forth, since it worked so well at her house I'd leave it there and buy myself this new 6500E. Now I know we both will never be w/o power again what ever mother nature throws at us and I will not have to "share."

Love the generator!!

I purchased my GP6500 primarily to run power tools. I have a large lot which makes it impractical to use an extension cord. I opened the box and followed the instructions on assembly which was easy (putting oil in the machine, wheels on etc.). I put gas in it and it started flawlessly. I have run a 15 amp table saw and shop vac simultaneously with no problem. In addition, I plugged in a power washer and ran it for hours without an incident. When you start it and hear it run you can tell it is a quality machine. It has a lot of power and runs very smooth. I even use it when I have access to power because I like it so much.

This a great generator and it is priced right.

I use my generator to power my house when the electricity goes out. It is sized just right for what I need. It is easy to start and set up. With the fold down handle attached it makes it very easy to maneuver the unit wherever you need it or to store it away. I have researched and used a lot of other generators and this is the best so far. I am very happy with this unit and I am sure it will bring me years of service.

Easy Start, Easy Connect, Generator and CO Protection!

A Great Friend brought me a Generic GP6500 he just bought that he only used for 2 hours. My Coleman hit the dust during the heavy rain of Florence. House was wired for generator and the GP6500 powered my freezer, refrigerator, lights and a portable AC unit during Hurricane Florence. Power has been out for a week with no problems. Rated at 40 amps the breaker lets you know when you are turning on to many circuits that add up quickly. Using LED lights through out your house helps on the wattage load.

Quality, Portable Power!

[This review was collected as part of a promotion.] This thing is a beast- in the best way! Its quality and I love the rugged wheels it comes with making it portable. The best feature is the tri fuel. It’s great to have multiple options to power it. Worst part is how heavy it is and trying to get the wheels attached.

Must have for hurricane season!

[This review was collected as part of a promotion.] This TriFuel Generator by Generac is going to come in very handy come hurricane season. Living in central Florida, a generator is a must have! This one runs on natural gas, gasoline and propane. We tried it first with propane and it started right up with the battery start, and it quickly shut right off when we closed to valve on the propane tank. Last year there was a huge issue with finding gas after Hurricane Milton, now that we can also use propane I feel so much more prepared!

Just what i expected!

I always do a major investigation before i purchase anything expensive.Sometimes it takes me weeks.I read everything including reviews.Finally after days of asking questions and reading many reviews i felt the Genarac GP6500 was right for me.I was right.Assembly was easy and took about 15 mins.Filled it with the oil that was provided and it started in two pulls.The unit was powerful enough to power up my whole house except the clothes dryer and electric oven.No more freezing in the winter or sitting in the dark.It is relativley quit and ran about 10 hrs on a tank of gas.I am very satisfied with my purchase and you can't beat the quality of Genarac.
