I love it.

I bought it almost 2 years ago, I haven't had to use very often, only when power is going to be out for a while, but it runs EVERYTHING in my home. No need to shut of anything, just hook it up, push the electric start, and throw the switch in my breaker panel. It's not one of the quiet ones, so I keep it about 100 ft from my home inside my barn and I don't hear it at all.

Junk

I purchased this generator in September 2013 and it started right up, no problems. We let it run a few minutes with the fuel shut-off in the off position until it ran itself out of gas to keep the gas from "dying" in the lines. I was thrilled at the time because I thought it was going to be a great investment. Not so much... I recently experienced 2 power outages and the generator will not run. Currently seeking a repair person to fix my BRAND-stinking-NEW generator. The machine doesn't even have an hour of run time on it. Highly disappointed in this purchase. If I had it to do over again I would have purchased a different brand.

Great power without breaking the bank

I had researched several brands and models of generators and this 7500W model topped the list each time. Bought it to run tools for home renovation jobs and backup if power was ever lost at home. Does everything I need it to do! Great power for the price! Only downside is noise. This is supposedly noisier than most in its class. This is not an issue for me, but if it was regularly used go home backup, I'd consider a quieter one for running throughout the night.

DEAD unit & useless warranty

WORTHLESS. Unit will not start, presumably due to dead battery (as many others have said) that will not take/hold a charge. Generac said they would replace the battery under warranty but after 6 months and numerous phone calls, the replacement battery has yet to be shipped out from the manufacturer.

Excellent Performance!!!

The RS8000E is a fantastic portable generator that performed admirably for 66+ hrs during a recent 72-hr power outage. I bought mine at the big hardware store that starts with the letter "M" and it was one of the last 2 they still had available. . It easily powered a fridge/freezer, 5 cu ft chest freezer, 1000 watt microwave oven, 8000 BTU window A/C unit, 5000 BTU window A/C unit, a mini-fridge, fish tank with heater/filter/bubbler, and several lamps with low-wattage LED bulbs. We took turns running the A/C units, never running both at the same time. My daughter even ran a hair dryer for a few minutes. The lamps never flickered, indicating that the RS8000E never struggled to keep everything powered. . The generator started up on the first pull every time in between gas tank fill-ups, which were less frequent than I thought they'd be. I was able to run it for 12-14 hrs in between gas fill-ups. . This generator is quite loud because it's so powerful, but we were able to run it overnight because our neighbors' houses are far enough away and they wouldn't be bothered by the noise. . I really like the convenience of the PowerDial, which eliminates the need to flip a choke lever, turn a fuel valve, and push the "On" button before pulling the cord like most other generators require you to do. . I highly recommend this workhorse of a generator. It saved us about $1,000 in frozen meat/food that would have spoiled, prevented our fish from dying, and kept us out of the dark for 3 nights. It paid for itself in its first use. . As a Wisconsinite, Generac is the first name that comes to mind when I think of whole-house and portable generators. You can't go wrong with Generac generators. So if you're thinking of buying the RS8000E, just go ahead and buy it! You won't regret it!

Fantastic Generator!

[This review was collected as part of a promotion.] This GP8000E COS W/Cord 49 St is a very high quality product. You will be impressed right out of the box before you finish the simple assembly with all the features. Generator started immediately the first time. No issues with operation. It is perfect in every way! I have never had any problems with it thus far. I like that it 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 at once! Highly recommend! You cannot brat Generac for quality and performance.

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.

Great generator. Manual needs improvement.

Excellent performance immediately after first start. Just what we need for sump pump power. Although assembly is not difficult, the manual for assembly could be improved: The parts could be better identified, and the pictures are too small to be of any help.

handles whole house

pro- whole house for me. 2.5 heat pump and any thing else I need in a power outage. Starts well; comes up to power right away. con- don't like the plug in underneath. My old 15,000 had it right out front. In my area we can expect an outage about every 2 months; sometimes lasting from 2 hrs. to 10 hrs. and even several days. Wouldn't be without my Generac.(P.S. I am a retired electrical employe)

This is the BEST product I was able to find in this price range!

I am so happy with my purchase! I never thought I would get a Generac brand generator large enough to run my whole house for so little cash. What a value and it is loaded with features and setting it up took less than 20 minutes. And a bonus was how easy it is to move and transport so if I wish to do some camping in a state or national forest I can have power to go for my fifth wheel. Love IT!!!!!
