A great tool for the price!!

I have used the generator as both a power source for remote power tool use and also as a home emergency power source. The generator starts quickly and works smoothly. This generator is virtually idiot proof. I like mine so much I bought a second unit for a rental property to be used as whole house emergency power.

Great product

Had to replace the generator I left behind in my previous home after 14 years of use. It was a Generac. I looked at several other brands, but settled on the Generac because of the reliability, wattage and value. Received it yesterday, assembled the wheels, feet and battery, and it started on the first try. Thanks.Tim31

Great to run a home

We purchased this unit for Hurricane season. Low and behold we needed it this year. This unit ran our house, all electric, 1900 sqft, with no issues. We ran on this generator for 4+ weeks until power was restored. We were hit again with another hurricane a few weeks later and had to crank up the unit again for a week or so. This unit ran flawlessly and we lived as if we had full utilities. Now there are some downsides to owning this unit. It is heavy and can be difficult to move at times. It burns a lot of gas. We were going through two tanks a day, roughly 32 gallons of gas. Due to it's size you will need to be able to store it for later use. Taken all of the aforementioned in account, it is worth having when in the time of need.

Delighted

Just received the new GP1800. It was easy to setup, manual is easy to follow with good diagrams and explanations, and above all it was easy to start. We have been hit with some terribly bad weather this winter (and flooding in summer) and I was determined not to be without power again. This unit will provide enough power for the primary needs. Wish it had a couple of more outlets but will manage fine. It is reassuring to have a good unit like this always available for use!

Saved our Christmas!

We were in the Michigan Ice Storm of December 22, 2013. Our yard looked like a war zone when it was over, trees pulled our power lines to the ground. I bought this generator on Monday the 23rd and got it running and hooked up to my fridge, freezer and furnace and several lights in no time at all, very easy to set up and run. It ran flawlessly for four whole days and nights, it would run 12-14 hours on a tank of gas. So glad I bought this, we enjoyed our Christmas with family, even though we did not have power to our house. Buy this generator, it will run your whole house!

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.

Great buy

With all of the weather associated power outages occurring these past years, I decided it was time to purchase a portable generator as a back-up . After looking at what was available, I chose the Generac because of its reputation as a reliable machine and at a price I could afford. Love my purchase and I'm not having any worries about its capabilities and performance. I'm now in ready-mode !! / Bonne achat pour me sécurisé en cas de panne d'électricité !!

Great Generator

I highly recommend this generator to everyone. My GP7500E was easy to set up and get started right away. It will be nice when the power goes out here in south Arkansas again and I can just start up my generator and not miss a beat. This generator will do all we need to do. Thanks Generac.

Great generator

This is my first generator, but we moved to a rural area where the power goes out regularly so we needed an backup generator. I was thrilled to be able to find a portable generator this size, because we can't afford a standby generator. I was so impressed with this generator when it arrived. It was so easy to set up and came with an extra air filter, oil filter, and so on. Very nice tough. I feel much better know we'll have heat and water if we lose power this winter!

This is a tentative review

Out of the box looks great, easy setup and starts easily 1x per month for testing ( starting) only). Today I needed it most with an ice storm and power outage. Fired up and ran great, but produced no electricity from the outlets. I took it into the service center, but still had a dark cold house. I will update with my service and warranty experience.
