Works great

Bought as an upgrade to a small generator during hurricane Irene (used with extension cords to keep fridge/lights running. We had an electrician hard wire the 7500E to the house in time for the October snowpacalypse (15.5" of snow, power out for 6 days). We have over 180 hours on the generator in 2 months, but for the last storm (6 days out), we were quite comfortable, and were able to run the dishwasher, septic pump, stove, etc. The power being out became a minor inconvenience. Aside from the quick *pre-dark* oil changes, no real maintenance beyond filling the tank twice daily. Very happy with the generator, and have already recommended the same unit to friends.

Worry free, two pulls and its on, plenty of power for all my needs

I bought this generator because of the Oct storm. We were out for four days (not again if I can help it). I had a transfer switch installed. I have two heaters (gas), refrigerator. hot water heater (gas) kitchen lights, dinette lights, bathroom lights, hallway lights and family room outlets hooked up to the transfer switch. No problem with all of it on at the same time. I run a line to the garage refrigerator. In the evening, I ran a line from my washer/dryer to the family room outlets. Again there was no problem. The generator is outside. I closed the garage door and the door to my house (there is no discernible noise from the generator) and after a while I forget I'm on generator power. It takes forever for this generator to run out of gasoline. I rated it five stars because (so far) there is nothing this generator has a problem carrying.

Best generator ever

[This review was collected as part of a promotion.] It arrived in excellent condition, assembling was very easy less than 10mins and worked amazing. I love that it has many functions and can power just about anything. Very useful now that the winter weather is coming and electricity tends to go out.

This product quit working

It only ran for 4 hours and stopped producing ac power to our house. When we needed it, it failed. I called and was given a number of a dealer that could fix it. It is now in the shop. I am waiting for it to return, fixed I hope. After my experience with this generator I would NOT recommend anyone buy one.

Very nice unit

Bought this generator for use as a power backup when power is lost for myself , other family members or friends . Received unit in a VERY timely matter , after installing wheel kit ( a must have ) , adding oil and gas the generator started right up , runs quite and smooth . Love the electric start and the twist Lock power cord that came with this unit , as of yet have not had to use it but pretty sure it will perform as needed , I would recommend this Generac GP6500E generator to anyone and it's a good value .

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!

Powerful

[This review was collected as part of a promotion.] What a powerful generator, it packs a lot of punch!! Great features like the electrical outlets, the size is compact and convenient and is actually a bit more quiet then I expected (it's not quiet, but definitely not the loudest I have heard) I think everyone would should have something like this for emergency purposes and recreational use. I would absolutely recommend this to all my friends and family.

Good machine. CO sensor and GFCI to sensitive

GFCI trips when I plug in my refrigerator. CO sensor keeps shutting down my unit that is placed outside not even close to my home. I had to put a box fan under the handle to blow air across the unit to keep it running. I dont need the CO shutdown. Other than those 2 items I am impressed.

Great overall unit but…

We purchased our generator just before hurricane Helene came through as our older generator of 20 years stopped working. The new unit worked fine for the week we were without power but started dripping some oil the last two days. After speaking to Generac and then taking it to an authorized repair dealer we were without the unit for almost six months due to no part available. Thankfully we didn’t need the unit as we never lost power during that time but that is way too long to wait for a repair.

Just what we needed for small home back up

This is just what we needed for a back up generator. We live in a very wooded rural area and power outages in the winter can be brutal when temps drop below minus 20. The GP6500 is perfect because it is portable and reliable. Now when we lose power during a winter storm we grab the generator out of the garage and plug it into the transfer switch and it keeps us and our house from freezing.
