Great product for the price.

I already had a Generac Pressure Washer and it has worked great so I did some research on their portable generators and they looked like they also had good quality. I purchased one a few weeks ago and it is a very well built generator. It has performed better than expected.

Initial impression of 7500E

After a tornado last November left us without power for 3-1/2 days, I decided to take the leap and install a transfer switch and purchase a portable emergency generator. I researched and looked at a lot of brands but always found myself coming back to Generac. I decided on the 7500 E and purchased it at a local big box store and took it home. Packaging was excellent and everything was in pristine condition out of the box. I inspected the frame and it is a very rugged design which I believe will give many good years of trouble free service. 30 minutes later I had it assembled, oil & gas added, and it started immediately when I pushed the start button. It is smooth running, quieter than I though it would be for its size, and easier to move around than I thought it would be for its weight, thanks to the sturdy fold down handle and wheels. I ran some garage loads on it to break it in and the voltage held steady at 119.8 volts regardless of load. I haven't used it in an emergency situation yet, but it performed exactly as advertised right out of the box. I am 100 % glad I bought this generator and I am very satisfied with my choice so far. I would recommend this generator to anyone who is looking for ease of assembly and more than enough power to keep them comfortable in any outage. Hopefully we won't have another tornado any time soon, but with this machine I am confident that we will be ready for whatever nature throws at us.

So far, so good. We'll see as time passes. Electrician recommended.

One minor part (battery wire terminal boot cover) missing from shipment that did not affect assembly nor operation so far. Will call Generac to get the part. Unit started immediately after assembly with no problem. Putting the feet and wheels on is NOT a one-man job without a jacking device or something to lever the unit. The issue is likely common to all brands. Connecting the battery terminals requires care to avoid shock. It would be better if the terminals were separated lengthwise on the battery, as opposed to both being along a "short" side, as presently configured. Oil fill is a pain, as it is on most small engines today. "Quality" is not only the power, but the long-term reliability. I have no reason to expect the unit will not last for years, but the short warranty period (all brands are the same) gives pause. Ask me again in 5 or 10 years and "average" could become "excellent".

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.

Great product

[This review was collected as part of a promotion.] Overall we have loved having this generator around. We did test it out with a few power tools and it works great. We have it ready to go for the rest of hurricane season. Right now we have used it for minor stuff just to test it out and so far it seems to hold up great. It is not overly loud for a generator. I will say it is really heavy and I am glad it has the handle to push/pull it. I am even more glad its handle can be moved in different positions.

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!

Good product value for the money

This served us well during Huricane Sandy when we were without power for seven days. It was easy to set up and safe for residential use. My only complaints would be that it is a manual start with a pull cord which is likely not a problem for most folks but more difficult for an older person. The noise level is a little bothersome too. Overall a good product which certainly did the job well. Next time I would get an electric start and hopefully a quieter model.

Very Good Unit

No big complaints. Strong powerful seemingly well built machine that delivers consistent power. I ran it continuously for 16 hours on 1 tank @ 1500/2000 watts. With cycling stuff on and off run time easily should go over a day. Things I don't like, battery doesn't charge while running the generator and no fuel drain valve.

It would have been nice if it worked when I needed it most

I purchased the Generac 7500E model generator approx 18 months ago from Costco. The deal that I got on it made it a no-brainer to buy there. After getting it home and out of the box, set up was a breeze. I simply put in the oil that came with it (we'll get back to this) and fueled it up, it ran like a champ. Every 4-6 weeks I start it up and let it run. I don't keep much if any gas in it while it is stored as I make it a habit to run it out of gas. This past week Mid-Michigan got pummeled by an ice storm that left us without power from Sunday 12/22/2013 at 3:03 AM until Wednesday 12/25/2013 at approx 3:30 PM. No problem right, I have a generator. I got up threw the breaker box to off, went through my start up procedure in the freezing cold of the night and had my house running with power again in approx 20 minutes time. After everything was back in order, I went back to bed and laid there listening to the generator. After it had been running for about an hour I heard it turn off. I went to check on it only to find that it would not start. I was full of gas and had been running just fine. The electric start had the engine wanting to fire, but it would not turn over. I got it into an authorized dealer the next day, Monday. It was not ready for pick up until Friday 12/27/2013. The diagnosis, it was overfilled with oil. Now, as I said, I set this up with the oil that was provided by Generac. As I remember it, a premeasured amount. I have never added to the oil. My only guess is that when my unit was tested at the factory, the oil was never completely drained. The time I needed it most and it had run the longest, less than one hour, IT FAILED.

This is the product to buy

I looked at many different generator brands online, and I kept returning to the Generac. I liked the idea that they build their own engines for their generators as well as the fact that Generac is a proven name. Plus, the price was comparable with other generators in this capacity range. Setup was simple, and the generator started almost as soon as I hit the switch. The electric start with included battery was also a big plus.
