Nice generator

[This review was collected as part of a promotion.] This geneator will be great when we are boondocking with our RV! It requires gasoline which is a minus for me because of the smell but at the same time, it is easy to find and purchase. This is a very heavy item, and you will need a friend to move it around!

Better safe than sorry!

[This review was collected as part of a promotion.] This generac generator is perfect for our needs and I'm glad we have it! Fortunately, we have not had to run it for an extended period of time since receiving; however, test runs have been successful and it seems like it will work efficiently and as expected for when we need it to run for hours. The generator came on a pallet and was packaged well. It is HEAVY without the wheels and handles. About 170 lbs I believe. So you'll want at least two people to lift (or just rip the box open like I did). Instructions are clear and assembly was pretty quick - about 20 minutes or so. It's definitely easier to assemble if you have more than one person. Once the handles and wheels are attached, it is easy to move around. While I'd recommend moving it with both hands, I was able to push it with one arm and record with the other and I'm not that strong. The generator itself feels very heavy duty and high quality. It seems like it'll last a long time. It's easy to start up and not excessively loud (it's a generator after all, so there is some sound to it running). I like that the wheels don't need air so they won't go flat. I also like that there are several outlets with attached outlet covers for protection. Lastly, as someone who is very anxious I greatly appreciate that this generator has onboard carbon monoxide monitoring. Overall, I'm incredibly satisfied with this generator and I'm happy we're prepared for the future!

Important to have!

[This review was collected as part of a promotion.] This generator is perfect for me in Florida due to the hurricanes and storms that cause massive power outages. Recently we had a 2 day long power outage and this generator helped to keep me and my family cool and kept our food from spoiling. What a life saver.

Dual fuel

[This review was collected as part of a promotion.] Being in Florida, you never know when a hurricane is going to come to having a generator is a luxury. This takes both gasoline and propane, which is nice if you can't find one or the other can be wheeled around and not too big to store.

A must have on the farm for power outages! We will

[This review was collected as part of a promotion.] I am very pleased with the Generac Dual Fuel Generator. I gave it a try on my farm and it effortlessly powered anything I asked of it. Skill saws, lights, anything! It was easy to assemble. Propane took a minute to get started but gasoline fuel fired right up. The only reason I knock of one star is the difficulty we had starting it initially. Noise level is adequate for it's size. I couldn't imagine the farm without it. It also provides me comfort to know it's ready when needed for one of our many power outages!

Lifesaver

[This review was collected as part of a promotion.] Down here in southeast Louisiana, you learn real quick that having a generator isn't a luxury — it's a necessity. I picked up the Generac GP5500E mainly for hurricane season, and let me tell you, it has already earned its keep. The electric start is a lifesaver when the power's out and it's hot, humid, and you're trying to get things running fast. It fired right up with no fuss. It's got plenty of power for what we need: fridge, freezer, a few fans, lights, Wi-Fi, and even the window A/C. During an outage, we barely noticed any strain on it. It's not whisper-quiet, but honestly it's about what you'd expect from a generator this size — steady and reliable. Fuel efficiency is solid too. I ran it overnight during a storm-related outage, and it sipped gas slower than I thought it would. Maintenance is also pretty simple, and the wheel kit makes it a whole lot easier to move around the yard. If you live anywhere that the weather can flip your power off anytime, the GP5500E is a great peace-of-mind purchase. Dependable, strong, and easy to use — exactly what you want when the lights go out.

Works as it should.

This was a warranty replacement for my 3300. I removed and applied thread lock compound to all the fasteners because of the previous generator failure. This new one works as it should. I don't like the handle because it collapses when trying to push generator backwards.

Great for moms when the husband is working the roa

[This review was collected as part of a promotion.] We absolutely love this Generac. Assembly took 20 minutes mostly because yes it is heavy. However, the wheels and handle are handier than a shirt pocket and make it so easy to move! I give 8/10 on noise level its standard for a generator and not super noisy! Plenty of plug ins you could plug in a house or camper! Best part its easy to start so I can do this without my husband being home when those winter storms hit!

Didn't even get a chance to use it/ it failed.

I bought this new generator new in the box for our deer camp. We unboxed it and added the oil and clean gasoline and started it. It was gushing gas out of the carb so we had to shut it down. When we called Menards to bring it back for an exchange they said that they don't take them back and we had to bring it to a certified repair shop that was 75 miles away from our camp. Needless to say, we didn't have a generator for deer season because the repair shop was booked. When I picked it up the owner said that the carb was full of gunk and that he couldn't even charge Generac for the repair because it was a fuel issue. how could that be possible when it was brand new out of the box? I am very disappointed that we have a generator that could be a lemon and the repair shop didn't get paid!

Easy to Start. Easy to Use.

[This review was collected as part of a promotion.] Out of the box assembly was fairly easy. I am not crazy about the design and setup of the handle. It's awkward and flimsy. However the frame is sturdy and durable. The two wheels make it very mobile. The controls are clearly labeled and makes it simple to use. It is easy to start using gasoline or propane. Runtime on one tank is about 8 to 10 hours. I've used it on the job site without issues. I am able to power a compound miter saw, table saw, floodlighting, and air compressor easily. Its rather compact size is good for hauling it from job site to job site. It fits into the back of a truck quite well. I also like the fact that it can operate on gasoline or propane.
