Batteries ship dead and no replacement available

Unit came with a dead battery and defective. Tried charging it with the charger they sent with it and it did absolutely nothing. Put in on a real battery charger and that didn't work. Generac said to put this generator in the trunk of my car and take it to a dealer. I certainly can't do that; it's too heavy and it won't fit. I called an authorized Generac dealer and she said most Generacs come with dead batteries. Even her replacement battery is frequently DEAD. This is the last time I purchase anything from Generac as their product quality is much lower than in years past. NEVER get a generator that can't be started manually with no battery. I will try a Dewalt or Kohler product next time.

Easy to maneuver

[This review was collected as part of a promotion.] Works great. Took it on our latest camping trip it ran our site and our neighbors site with power to boot. Quieter than I expected! I liked the idea of never flat wheels but they seemed a little bent. Handy fold up handle that was well balanced and easy to maneuver was a bonus.

Awesome Generator

Great quality product as expected from Generac! Runs everything I need during a power outage with ease! After buying portable Generac I'm even more convinced to purchase a standby down the road! Then I'll be able to camp and tailgate exclusively with my GP6500!

Electric starting is simple.

Only used in one power outage. Handled two fridges, a furnace, large TV, some lights without a glitch. Easy to manuver with the furnished wheel assembly. In the process of installing a seperate manual transfer panel to hook up 30 amp twist lock into the house.

Quiet running Generator

I'm very impressed with this generator. After going without power last year for 5 days after hurricane Irma, I decided we needed a generator. After looking for months as to which one I wanted, I decided on the GP6500. It has the power I need in an emergency situation and is very quite compared to others I have experience using. Fired right up on the first pull and my girlfriend can start it also should I be out of town and the power goes out for an extended time period. Good value for the price and I like the dependability and Generac reputation.

Very pleased!

This is a powerful unit that will meet our needs during an outage. For us, it will power the heat strips on the furnace, our water pump, the refrigerator, microwave and enough lights to see our way through. We are very happy with our purchase and as we always say...we hope we never have to use it!

Works nice

[This review was collected as part of a promotion.] Look like it’s pretty easy to maintain. The noise level isn’t too bad. I will add a video later of that. It is heavy and once you get the wheels on in the handles, it makes it a whole lot easier to move around, but you still know you’re moving something because it is heavy. It works very nice. I really can’t say how it’s going to hold up. I can update that later, but it looks like it’s made very well and at any time you have any problems I don’t know what’s going on. It has a one 800 number for you to call and they will help you out and I love that. It has a five year warranty And that it runs off of propane ,natural gas or gasoline. And this is the perfect time for us to have a generator with the electric going on and off with all the storms and everything. I am so happy with this.

Nice generator

Bought this for mainly pump water and freezer during power outage. Put it together and started on first pull. Ran great. Just a little loud. Loader than a lawnmower, but worth the money. Nice to have during those ice storms. Would of giving it 5 if it wasn't so loud.

Great generator

I love the generator. It works excellent, just as expected. Starts immediately and runs well; provides the power I need when required. The only complaint I have is the noise level when running. Surely Generac could or should have equipped the generator with a muffler system to quieten the sound emitted.

Well made, easy to use

[This review was collected as part of a promotion.] The Generac generator arrived in a large box and was pre-assembled. The product is bright orange making it easy to spot in our unorganized garage. It was easy to use and instructions were simple. I would recommend everyone has a generator in their home in the event of emergency or prolonged power outage. This would easily power our freezer/refrigerator. It is also compact enough that you could take it camping or to an outdoor event. The only small complaint would be with regard to packaging. As we all know, items shipped get banged around and my generator had a small crack in the outer plastic casing. It was nothing that prevented it from working properly but if it was shipped further perhaps more damage would have been done so I would suggest more padded materials inside the box.
