Easy out of the box assembly.

Easy out of the box assembly. Took about 20 minutes to assemble. Everything you need in the box except the gas. Filled with oil, charged the battery and started right up. Noise level is less than I had expected....that's a good thing. Looking forward to using the unit for home backup.

Comfort after the storm!

This product was a life saver for me and my family after surviving Hurricane Michael. It’s loud but it does it job and does it well. We were able to keep our house running for day without power. It runs about 10hrs on a tank of gas and it had enough power to run our whole home. Then after our power was restored it was used to help others until theirs was restored. This generator was a great investment, don’t be like my family and wait until you absolutely need it, buy one now and be prepared for anything!

There are still great purchase experiences to be found.

From sturdy packaging and clear instructions to quality manufacturing and ease of use, nothing could make for a more satisfying purchasing experience. Thank you Generac Team for a clearly superior product. Pride in all aspects of your company is evident and appreciated. Joe

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.

Great, easy to use unit! Powers plenty!!!

Like so many others, going 7 1/2 days without power during the freak October Nor'easter SUCKED! I bought the GP7500E for back up power. Great unit! Easy assemble out of the box....was up and running in 15-20 minutes. We will never be without power. What a relief knowing we won't have to go throught that again! I recently had a friend who's an electrican install a 10 circuit transfer switch. This unit has plenty of juice to power everything we hooked up and then some. Hopefully we won't have to use it too often but, if it goes dark again.....we're ready! Thanks Generac

Good value for the price

I looked extensively at generators prior to making my purchase and this one had more features and value for the price. Was very easy to set up and start up can be done by anyone. Would recommend this product to anyone looking for a portable generator.

Excellent quality product with a great reputation

After 5-6 months or research, I selected the GeneracGP8000E for a whole home emergency backup system, had it installed and am very pleased with this purchase. It is easy to start and maintain, and surprisingly easy to move around given its weight. It's noise level when running is satisfactory and I am looking forward to a worry free winter.

Easy to assemble, great sturdy quality, and started on the first try

I have been wanting and researching a potable generator for years. With this, the generac name continued to rise to the top in quality and performance. Then came an immediate need, and after looking at my options I decided to go with generac. Even though the decision called for a quick decision I was confident that I was making the best decision. I found what I was looking for at Lowe’s and actually upgraded from a 6500 to the 8000, the price was right and it came with an electric start. I brought it home and within 2 hrs had it making electricity! The ONLY down side of the whole situation was that they advertised that it with idle control and it turned out it didn’t. Please correct this. I give this product two thumbs up!

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.

Features and price

So far I am very satisfied but did not get a chance to put it to an actual test. The predicted storm did not materialize and we never lost our power but I was confident that I was ready for anything with my new Generac 7500E. It was filled with oil, the battery charged and gas. Test started and it fired right up.
