Nice and Quite

Had to replace my old generator (That was not a generac) that had for the last 15 years. Bought this from a local vendor. The unit started right up. I already have a generac home standby but It really uses the propane to run all night. I use this to just run fridge and furnace at night. The home standby was the best purchase ever. Soon as the power goes out the standby will start right up. I have the 6500 run just a few circuits when don't want the standby running. The 6500 has electric start which is nice. I was without power when 1st bought and it ran for 16 hours straight. No problems. I would recommend the generac name to anyone. After bought my home standby my inlaws bought one and love it. Highly recommend the portable 6500E.

I'm pleased overall with the features and output.

I was surprised that the THD was high enough that my digital frequency meter would not read 60 Hertz either at no load or full load. I had to read the frequency with my ocilloscope. However the THD must be low enough so that it doesn't seem to bother my electronics. It starts easy with the pull starter. I'll probably use a bigger starting battery when the little one that came with the unit dies. The voltage is pretty stable during motor starts. Since the genset is heavy I would like to see a lifting eye to set it in a pickup bed. All things considered, it seems worth the affordable price for an 8 KW non commercial machine.

This generator is really worth the money.

I just purchased this generator and it was very easy to put together right out of the box. I followed the instructions in the book and added the oil and then gas. I turned the choke on and then hit the start button. The generator started right up. My friend who was helping me thought it was going to be louder than what it was. I too was surprised at how little noise it made. I then tested the voltage in all of the plugs. Everything was right where it should be. I hope I do not have to use it as a backup, but if I do I'm sure it will do the job with no problems. I bought this for our house for when our power goes out, which happens quite often. I also bought it with the intention of using it when we build our log home. I know it will be able to power all of the equipment while we work.

Excellent quality, design and reliability

I don't write many reviews but we are in an ice storm power outage. I dusted off my Generac 6500 XL which I purchased in 1999. It started right up and is running my entire house - well pump, furnace, frig, and lights including Christmas lights. . It is 17 degrees out. This generator is great. It starts first or second pull every time. It will be hard to find a replacement to match this one if it every wears out. Happy generating.

Excellent Quality!!

[This review was collected as part of a promotion.] I received this Generac GP6500 portable generatoras a free sample. I think the quality is excellent. I tried it out right away to see how it performed. It started on the first pull and was able to power all the essentials in my home. I am very pleased with the performance and quality of this generator thus far. I would definitely recommend this product to anyone.

Good Product

[This review was collected as part of a promotion.] The unit was package very well and sturdy in the box. This is my fisrt time assembly a generator and this one was pretty easy. It only took about 45 minutes. I test this unit for about 4 hours for a total of five days. It is not as loyd as I thought it would be. No problem hooking up my cords. It has a twist adapter which is a plus. It also show how long you have for power. Lastly, I finally took this to a tailgating event. This works so well. Everything worked so well.

Glad I got this unit

After researching for almost a year, and talking to countless other generator owners, I decided on the Generac line of generators. After extensive comparisons of the Generac portable generators, I decided on the GP7500E since it had the electric start. From the time I ordered until receipt took about five days, and it arrived in great shape, no shipping damage or missing parts. Assembly was a breeze, and in approximateyl 30 minutes, I had the unit assembled and started up. I ran the unit for about an hour, load tested the 30 amp circuit, then packed the unit away in the garage to await the next power outage. One thing to remember about this unit....it's heavy, right at 200lbs, but once it is assembled, the design of the handle makes moving this generator around a breeze.

Leaking Gas - Brand New!

Selected the GP7500E above two other choices. Assembly was easy but, I was filling up the gas tank and the gas was leaking out the carb almost as fast as I was pouring it into the tank. Called customer service and found out this is a know problem! Now, instead of taking it to our cabin this weekend, I am taking it to a Generac Service Center. Very unhappy that it is leaking gas out the carb and it is a know problem! Maybe I will get a gift card for all my problems.......but......I don't think so!

Mine is the GP5500 and it can't wait to start

I needed something in a hurry. Looking for a Japanese product. My friend owns two ACE hardware stores. They only carried Generac. Made in America. Shucks! He told me Generac made top quality stuff. I bought mine in a jam. Delighted. This baby longs to start up! Dying to start up! on the first pull. Reliable, noisy as all get out-no problem. I surround it with some boards-it produces tons of power. Runs forever. I will buy another one. You will love yours .

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!
