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.

Excellent generator.

This generator came well crated and delivered on time. I was impressed with the ease of start up and was amazed at the included maintenance kit. (extra spark plugs, plug wrench, primary and secondary air filter, oil filter). I have not had a chance to power the entire house with the unit but it starts easily and runs strong. Although I do not look forward to a lengthy power outage (which has been more frequent lately in my rural setting) I feel much more at ease having a well built machine as a back up.

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!

Wow! This generator really cranks out the power!

[This review was collected as part of a promotion.] We use a generator to power our tailgate parties at football games. The person who normally brings the generator had his stolen so this is perfect timing! We tested it out and it has plenty of oomph to power the TV, satellite dish, mini air conditioner and various heating and cooking items we need it to. Not only that, but living in a hurricane prone area this will be a lifesaver when the power is invariably knocked out! It's not as noisy as I expected either! Yay!!

A great backup system

We had a standby 12K natural gas backup generator from Generac in upstate NY and when we moved to eastern North Carolina we had nothing so we decided to go with a portable. Purchased the Generac 7600E (electric start) and had a electrician wire a 10 circuit panel into our house circuits. When the power goes out, we just plug the generator into the house circuits, start it and turn on the house circuits 1 at a time. Works wonderfully. My only wish is that the electric start battery system had a meter to tell the user how much voltage was left in the battery. Overall cost about $1500.

Excellent quality and features for the price

I bought this generator on the recommendation of a friend who has this same one and from all of the positive reviews that I have seen online.Upon receiving the generator,the only thing that I had to do was (easily) install the wheels and handle,connect the battery and fill the oil(included) and gas.It started right up.I really like the electric start feature,my wife will be able to start it if I'm not home.I haven't had to use it yet in a power outage but now I'm ready.

This product works great

The only problem we have is the manual and the website is useless for this model. Changing the oil is NOT as instructed in the manual or on the website. There is no plug for draining the oil. Also, finding the "Serial No." is impossible. It is not where you are directed to look by the help line, the website, or the manual.

Ready in case of need.

Fires right up and hardly needs to be choked. The airless wheels make it easy to maneuver. The handle that raises/folds also makes it easy to move. Haven't had to use it for a power outage...yet, but have tested it on power tools and it ran them without any problems

For the price, should have flat-free tires and covers on outlets.

I'm pleased with the overall look and the attention to engineering details. The generator appears to have been designed for ease of maintenance. I like the location of the oil dipstick, oil filter and the oil fill on the engine. I also liked the oil drain hose which will make it easier to not make a mess when draining the motor oil. I would have liked for it to have flat-free tires. This generator will be stored for long periods of time between use. I do not look forward to having to air up tires when I need to move it to where it will be needed during a power outage. I would have also liked covers over the electrical outlets to keep mud daubers from plugging the outlets with mud during storage. I have not used the generator yet, but overall I like what I see based on decades of experience as a railroad signal maintainer running generators at signal locations during power outages.

This is the one!

I bought this unit because I am building a house in the country. Com Ed won't have power there for another month. It took all of 10 minutes to put this together. total 15 minutes from box to running. Loaded it on the 1st start, Wow, this will run everything I need it to. Then after the house is built, it will serve as a back up in power outages. Illinois doesn't have the best of winters out here in the country. I recomend this to any one serious about a quality generator!
