Best " bang for the buck"

After researching and using other products, such as Honda. I could not help but know that my GP6500 is the best bang for the buck! I know the dependability of generac having owned one in the past ( used it as an enticement on sale of my previous home). This particular model will also give a surge of power when increase of load is needed . With proper maintenance there is no reason it should not last a very long time. Very comforting to know the dependability of the generac name. Living in Florida having dependable back up power is essential. Sleeping better knowing I now have it!

I’m ready for the winter season

[This review was collected as part of a promotion.] This is my first generator. The delivery was fast and efficient. They even have a number you can call to find out your two hour window. It came packaged nicely in a box but it is very heavy. I love all of the features! It’s portable, comes with the plug in battery charger, foldable handle and push button start. I’m so happy I can finally feel at ease this winter season as we lose power frequently! I would definitely recommend this product to anyone looking for a generator!

Good value.

Starts easily using the pull start. Would think the electric start would be fine for an old lady. Like the extended run time as the unit uses so little fuel. I'm using 100% straight gasoline with a bit of Seafoam added which should give me a fuel shelf life of two years if need be. The use of an Generic safety transfer switch (nicely prewired) and an alm. Generac inlet box completed a functional and good looking insulation. We are using eight circuits which required the addition of two mini breakers in the Generac switch panel. That's no problem for an electrician. Bringing the system to ten circuits requires an additional breaker box. A bit noisy but not too bad. My wife says it's "a life saver."

Excellent value

Just got it. started perfectly without any issues. Easy to move around. Everything as advertised. Have not used it for power yet but have high expectations. Not nearly as noisy as i thought it would be. Not any louder than the poulan pro 6600 which it is replacing.

This product has great features

So far I only have had it for a week. It is smaller and lighter when moving it around compared to my old generator. I am slowly checking out all of the cool features it has. I especially like the ability to charge the battery just by plugging it in. and the light that will show when the battery is low. Larry

Great value for the price

Purchased the GP7500E (special sale price) at Canadian Tire. Assembled and started right up on first try. Appears to be a good quality unit, great value for the price. Just wish it came with a float charger instead of the supplied batter charger so it could be left plugged in at all times.

Good price excellent product

Have installed and maintained Generac Whole home generators. So I am familiar with the quality , ease of Operation and maintenance of Generac products. Bought this for home backup After electrical outage. And with ice storm on its back fully anticipate using it. Am pleased with what I've seen and will add another review if I use it with my thoughts on product.

Very nice generator

I bought this GP7500E to replace an old Coleman generator I had, and I'm very impressed. It's quiet, it assembled easily (install the wheels, install the handle, hook up the battery, add oil, add gas, and done!), and it powers up my house easily. Here in Nova Scotia power outages have become so frequent that a generator is necessary. The only thing it won't run is my electrical baseboard heating, but no generator even approaching this wattage or price range will do that.

Came just in time for Hurricane Season!

[This review was collected as part of a promotion.] I’m really very pleased with this generator. We live on a South Carolina barrier island and we can get hammered during hurricane season. I love that it can run on Gasoline, Liquefied Petroleum Gas or Natural Gas and you can switch between them. It has a large capacity fuel tank and extended run time. The delivery guy was super complimentary of this specific model and Generac in general. This gives us such a sense of security, knowing if a storm knocks our electricity out we’ll still be able to run the fridge, lights, tv, electric range, etc. 9500 running watts with gas is more than enough to keep us comfortable. We lost hundreds of dollars in food last season plus, it was SOOO hot. I’m glad we won’t have to go through that again. It’s easy to set up and easy to use. The fact that it’s portable is super convenient, the wheels and handles make it easy to move around. I can move it easily, so can my 71 year old mom. Our handyman says he wants one for working contracting jobs. COsense® Technology gives protection against carbon monoxide. The electric start is a really nice touch. This model has so many nice features, it’s a really wonderful unit and the feeling of security makes me wish we got one a long time ago

GREAT GENERATOR. ORDERING PARTS VERY DIFFICULT !!!

After a lot or research I purchased two 2011, 6500e generators, one for my parents and one for my sister. Other then one generator being shipped with one end of the fuel line disconnected because of a missing hose clamp, the units seem to be great machines and well built (haven't had to use them and have only run them for a few minutes). However, we broke the AC/DC Adapter cord that keeps the battery charged, its made out of a very flimsy thin wire. Well, trying to find this simple part has proven to be an exercise in frustration and this is why I don't recommend the product anymore. Three dealers I visited don't stock it, even though I bet it has to be the most ordered part because it's so flimsy and easy to break. I can't locate the part on the generac website or on the internet, no matter how you word it, the part can not be found. My mother, my girlfriend, my sister and I have spent many hours trying to find this part. I traveled 60 miles to three dealers only to have them tell me they can't find it anywhere. And NO the AC/DC adapters at Home Depot, Lowes, Target, Walmart, and Radio Shack, even the universal ones with lots of different ends, don't properly fit the generator !! The store adapters are all 12 V and the one that came with the generator is 14V. The part is >> AC/DC Adapter, Model YP-018. (Specifics are 120v-60hz, 20W, 14vdc, 800 mA, 11.2 VA). I own a 16 year old Sears 3500 generator and ordering parts for this machine is very simple.
