Amazingly powerful and still portable!
We absolutely LOVE our new generator. We can run all the critical items in our home during an outage, including our ductless A/C unit!

We lived through hurricane Matthew last year and with a new storm season on us again here in FL, we bought this generator.

Its as close to 'stand by' as we can afford - and we couldn't be happier to have it!

Great power output; too heavy to carry around for camping.
This 8Kw machine was purchased to replace a Coleman 4Kw machine because, like many users, we initially underestimated our power needs. A sparsely used cabin in the woods, off the grid, but enjoyable getaway doesn't warrant air conditioning or television, but a water pump and a hot water heater alone quickly outstripped the 4Kw output of the previous generator. We had to choose between 1)pumping/heating water and 2) lights, computer, power tool, or battery chargers. It was a tolerable choice for a couple of years, but purchase of a KillAWatt device quickly demonstrated the actual consumption of power we were using at the cabin. The 8Kw output now affords us the luxury of hot water and lighting simultaneously, so we are now considering an upgrade to a small refrigerator. The Generac product line is seen all over the north woods up here in upstate New York, often as standby generators, but a few portables as well. This one is very heavy, and is not liftable to put into the vehicle to take to another site for a hunting trip or other event, so it needs to stay put. After using it for two weeks, a few bolts and nuts had vibrated apart and were sitting on the ground, so it prompted us to go around the entire unit, tightening all accessible bolts, nuts, screws, etc. The loose ones were limited to the frame and housing area. The motor/generator components were well manufactured, and we were reluctant to over-tighten any mechanical systems. Hooking the machine up to our house was straight-forward, because we had already set up the previous system with an electrician. The larger capacity Generac did require a 240 volt / 30 amp connector plug to upgrade the milder plug used by the previous generator. Also unforeseen is the simple fact that an 8Kw generator can use twice as much gas as a 4Kw generator. We're not saying the Generac is less efficient, but having the power available whets the appetite of the user. We are still re-thinking our power needs daily because of the reality of gas prices. 24 hours of full-out use will cost $15 per day, but miserly use can cost only $5 per day. The choice is up to the appetite of the user. What's the difference? Running the water pump and water heater all day and all night pulls a lot of watts. Replacing incandescent light bulbs with efficient LED bulbs makes a small but noticeable difference. Chilly nights sometimes tempt one to plug in the electric heater, but power costs money. It's better to use extra blankets if you have them. It is comforting having the power when you really need it, and this machine has it if you want it. Given the cost of fuel over the course of the summer, and looking to the future of several summers ahead, we plan to supplement our electrical generator with solar and wind to manage the cost and reduce the carbon foot print.

This generator is an excellent value for the pro e
The 8000 starts easily. Provides good and reliable power, and is not loud. I have enjoyed using it to power tools on our farm and have already tested the backup power potential. Works great.

This generator really works well. I love the electric start. As a senior citizen it's great. Since we live in the country our power goes off every once in a while. This generator supplies power to my well, furnace, and most of the house very well.

This is a great product
This product gives us more for our money. After being without power for 38 hours and losing everything in the refrigerator and freezer for the second time this year we decided to buy a generator and generac was rated as one if the best. Bought one and had an electrician come and install it so from now on we have piece of mind when the power goes out again. Price and the ability to power so many things at once was a no brainer. Thanks for the great product.

Very high quality produce with lots of features
This unit is a very high quality product. You will be impressed right out of the box before you finish the simple assembly. Lots of features. Reminds you when maintenance needs performed. I especially like the four outlet cord that comes with it. This cord allows you to use both legs of the 240 volts instead of just one side. This gives you the ability to use the full rared output of the generator not just 1/2. The receptacles on the control panel also allow for this same usage. the automatic throttle control saves fuel as I usually do not need 8000 watts of power when dry camping with my RV. I just retired from 47 years in factory skilled trades maintenance and I am a skilled trades instructor at a local 2 year college and I am very impressed with this generator.

Purchased in 2014
I live in North Georgia, we have ice storms and snow storms and tornadoes, even tropical storms that knock out our power from time to time. My house was prewired for a generator and has a transfer box. This unit was pretty much a plug and play situation. It easily runs the heart of the house more then adequately. For the last 3 years we have had to use it for every year for anywhere from 4_days to 2 weeks and we ran it 24/7. Other then changing the oil and replacing the starter battery, its been maintenance free. I heartily recommend this unit to anyone that needs a generator.

$$ Best Bang For The Buck $$
Having done extensive online reviews and talked to several folks that own similar sized portable generators I confidently made the decision to buy the Generac 8500E. I ordered online, it arrived much sooner than expected and after the installation checkout it started the first flip of the switch! Buyers can trust this generator to meet their critical needs, I certainly know I do!

A Little more comfortable in the wake of the storm.
We have been thinking of a whole house backup but waited a little long, Irma hit. I ended up picking up a generator as I traveled back to FL as all the ones in town were gone. I was looking for a large enough one to run our well and refrigerators as long as needed to get power back. I arrived back to the house the day after the storm there was no power. So I opened the box and added the oil provided in the box, added gas and connected the battery, also provided in the box, turned on the fuel and slid the chock lever and hit the start button. the generator fired right up and we had power again. It was a good experience and easy to set up. We have had no problem so far.
