6500 Watt Generator with CO DETECT
6500 Watt Generator with CO DETECT is rated 4.8 out of 5 by 297.
Rated 5 out of 5 by from perfect fit I needed this as a backup for a farm to keep things going if the power go's out during the recent hurricanes and it was super easy to assemble (less than 10 minutes) once assembled it is really easy to move around by myself. And it started with only 3x pulls on the starter cord the first start and one pull after. This is a pretty good sized generator so its not exactly Quiet but I needed the higher kw output to run 210v well several refrigerators fans and lights and a small quite one was not going to do it all. This will. It also has a nice meter that tells voltage, hours, mhtz, and kw, . It ran everything I needed it to and can run more.

Rated 5 out of 5 by from Survivor mode!!! Come on, guys. No matter how tough you pretend to be-if you look long enough into the darkness you will feel the hair on the back of your neck and your arms rise with the sudden fear of not being able to see what may be out there. I am surrounded by 22 acres of forest-and believe me when I say this generator keeps the monsters away and the heat in when I need it. Easy to hook up-easy to fill and start and easy way to give you peace of mind. No problems what-so-ever, and it's well worth the more than fair price. Don't just survive-be sure you survive. This product is a guarantee you will.

Rated 5 out of 5 by from Ryobi generator so their was a bad storm that came thru my town. It knocked out 4 electrical polls. I'm all ready a hugh fan of ryobi tools so went to the depo and found the biggest ryobi generator they had. Got it home set up was very easy. Got fired up and running hooked up to deep freezer and 2 refrigerators so I didn't lose food. Generator ran like a champ. I have since got the house adapter wired to the fuse panel so bring on the storms im ready. The only thing is that it only comes with one thing of oil its not enough to fill unit up make sure to buy extra oil other than that im really happy with my purchase. I will continue to buy ryobi tools

Rated 5 out of 5 by from A great generator I bought this in anticipation of extended power outages from Hurricane Laura. Unboxing, assembly and preparation was very simple and done in a few minutes and very few steps. It started on the first pull which was amazing. We ran it continuously for 4 days only stopping to refuel and one oil change. I particularly like the easy to use hand-truck style mobility. This is an improvement over other generators I've owned with a simple handle to lift and roll. I only ran 4 fans, lighting and entertainment items and got 12+ hours on a tank of fuel. Everything is heavy duty and I expect it to last a very long time.

Rated 5 out of 5 by from Generator We bought this machine approximately 3 weeks ago , We live in Maine on a pond had some serve weather with high winds we lost power. My husband has a breathing machine and out other generator less than 5 years old wouldn’t start. He didn’t sleep all night left the house at 5 am to get to Home Depot as they opened and was able to buy this amazing machine. Thank god as we had no power for 3 days. This machine let him get the much needed sleep he slept well it runs our entire home with no problem. Thank you Ryobi we are very pleased with our purchase and plan to buy more products in the future. Sandra Jackson

Rated 4 out of 5 by from Excelent Generator for a great price. The generator is quite robust and solid. The first start-up was quite simple. The cost-benefit ratio with other brands is very good. Compared to another generator that I have, this one resists very well the starting peaks of the equipments. My only drawback is that the generator runs in a large yard but in a small shed to protect it from the rain. The shed has three half walls and therefore, when used for prolonged periods activates the CO sensor and turns off the equipment and you have to wait a while before you can turn it back on. You should have a way to vary the tolerance of the sensor or overided it.

Rated 5 out of 5 by from update from first review with issues purchased this generator for the hurricane, it started on first pull but there was an issue with power output. Had to bring it to service center and there was a wire that shook loose in transit that once reconnected put everything back into working order and it passed all the load tests with flying colors. brought it home and tested it out on my own, still started on first pull, connected it to my deep freezer and ran it for a few hours so it put a drain on the generator and it never bogged down or showed any strains to keep up. Very happy with my purchase and now i am ready for the next storm!

Rated 5 out of 5 by from Runs like a champ!!! I bought this a little over a month ago, right after Hurricane Michael. Started right up and worked great. Luckily for us, we got power back within a few days. But when I went to help an old Navy vet friend of mine, he did not have power and they had a old generator barely running. We hooked up my new Ryobi generator and it ran non stop for about 5 weeks. It never slowed down and we were able to hook it up directly to his house, with the help of an electrician. It ran everything in their house except the main A/C, but they had a portable A/C for their room that worked. This generator made life a lot easier for my friend and his wife. They went 6 weeks without power and thanks to the quality of this generator, they had power, water (well pump) and A/C. It's super easy to start.
