Indestructible!!!

I've only got about 10 or 12 hours on my 6500 but I am amazed at how it performs after surviving two floods in my garage!!! Both times the water got high enough to fill the muffler and reached the electrical outlets. Both times I drained the water out, checked the carburetor and changed the oil to be safe. It fired up, steamed out the remaining bit of water in the muffler and ran as though nothing had happened. I was sure I was going to have to spend a lot of money to get it up and running again. I'm very impressed with my purchase. I'm staying with these guys.

Very useful

[This review was collected as part of a promotion.] This generator is easy to use and is very convenient. Yes, it takes up some room in your garage and you might not use it frequently, but in Houston hurricane season it is worth it to be prepared. This won't power your whole house, but it will keep the refrigerator running and a couple other things powered in the event the electricity goes out.

Hurricane Auxiliary Power

I bought a GP8000e 3 years ago but didn't need to use it until now. I turned this generator on Wednesday night after hurricane Ian had passed. It's been running for 5 days straight. I do change the oil every day, not sure if that's necessary. It's been running the lights, two air conditioners, tv, refrigerator… I've even used the washing machine.

Very Satisfied

After returning the original purchase due to a defect, the replacement generator went together quickly and easily. I was concerned about previous reviews that talked about difficulty putting oil in and putting the wheels on, but I had no problems. You do need a funnel to add oil, but a funnel with a long neck worked fine. After the unit was assembled, I put some fuel in it and it fired right up. I also put a small load on it to ensure it was actually working. All in all, I'm happy and confident this unit will perform as expected when it is needed.

Great Portable Generator

A portable yet powerful generator that is well suited for home backup power needs. Wheels and collapsable handle make it easy to manuver. Electric start makes it a snap to fire up. Enough output to protect freezers and fridgerators. 240VAC has enough output to power a well pump.

Awesome!

I picked up my Generac 7500E portable generator after I found out that our power would be out for possibly a day or two. I panicked and spoke with a few friends and they all recommended a Generac generator. Set up out of the box was simple and I had both of my fridges and my chest freezer back up and running in no time. I was also able to get my well pump, a few lights, and the TV going. I didn't miss a minute of the football game! I am so pleased with this product and will never have to stress on what to do when the power goes out!

Awesome generator. It's super easy to use.

Love this generator. It supplies all the power I need to run essential circuits in my house, and then some. I love the push button start and the start and stopping instructions printed on top of the machine. Cooler yet is the fuel saving auto idle switch and all of the receptacle options. This thing does everything. Finally, while it's a heavy generator, the wheel kit and large handle bar make it easy to move around.

Great product right out of the box!

I recently purchased two GP8000E CO2 sensing Generac, one for my house and one for my Mom. Easy to put together, start, and store! They start right up and are surprisingly fuel efficient. My Mom is 71 and has no trouble starting and operating the generator! We have used it several times since June and have been very pleased!

It does what it's supposed to

After 35 years at the same address and typically dealing with 1 or 2 mostly short outages per year, we experienced an 8 hour outage and a 5 hour outage within 2 months. My wife said we need a generator! We looked at whole house backup but that seemed like overkill and very expensive. After lots of online research we settled on a Generac in the 6500-8000 watt range. Because we have a well, we needed 230v output. The price difference between 6500 and 8000 was so small, we opted for the GP8000e. The installer put a lockout on our electrical panel so we can switch between generator power or electric service but the generator cannot backfeed the incoming electric. Yesterday we experienced a 5 hour outage. After 30 minutes, I rolled the generator out of the garage and onto my patio. It fired up with electric start even though I had not charged the battery since the initial startup 4 months ago. I hooked up the 30amp cable to the receptacle on the house, switched the lockout on the service entrance to generator power and we had power. In addition to the well pump, furnace fan, and fridge, we ran the microwave, an electric cooktop (not at the same time), and all the lights we wanted. My only complaint, though not unexpected, was the volume. It is loud! My phone sound meter app registered 90db at about 10' away. It was about 8' from our family room and even with the windows closed, it was too loud to watch TV comfortably so we retreated to the basement. It's also quite heavy but I had no real trouble wheeling it around the house from the garage to the patio. Overall, I'm very pleased with it and my wife was happy that we had water and a cold refrigerator during our 5 hour outage.
