Easy to set up and use

[This review was collected as part of a promotion.] What a fantastic product! It is so easy to set up and use. The noise level seems to be slightly better than other generator brands. The only con that I have is that it is hard to fill it with oil with the electric start battery and wires at the oil fill location.

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.

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!

Amazing Generator!

[This review was collected as part of a promotion.] This generator is great! I love that it is dual fuel, and even comes with a nice propane quick disconnect hose. It was super easy to assemble and setup. It was also pretty easy to start up and is decently quiet. Overall, really impressed with this generator!

Easy, reliable portable generator

We bought this two months ago and while not having to use it yet, in preparation for the NE winter that'll be here before we know it, did gas it up and test started it twice since. It was very easy to fill up and run through the steps with no problems. Both times it started immediately. Knowing we have a reliable portable generator will ease our worries significantly!!

Big and durable

[This review was collected as part of a promotion.] It's been very cold in Wisconsin so I did not have the time to assemble the generator onto its wheels, but I will get to that soon and update my review if needed! This is a very sturdy, powerful and durable piece of machinery. I'm happy to have this for peace of mind if we were to need to use a generator!

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!

Reliable and easy to setup!

[This review was collected as part of a promotion.] I received the Generac GP5500 Single-Fuel (50-State) from Influenster and Generac in exchange for an honest review, and after using it during a recent outage and for a few home projects, I'm genuinely impressed with its performance. The GP5500 has power to spare. It ran all of my essential home items—refrigerator, freezer, Wi-Fi, several lights, and even the microwave—without any strain or noticeable fluctuations. I've also used it to power a couple of heavier tools for outdoor projects, and it handled everything smoothly. Starting it is surprisingly effortless. The recoil start consistently comes to life on the first or second pull as long as the basics (fresh fuel, clean oil) are in order. It's refreshingly straightforward for a generator of this size. In terms of noise, it's about what you'd expect from an open-frame unit—comparable to a lawnmower at a reasonable distance. Audible, yes, but not disruptive or harsh. The fuel efficiency is another standout. One full tank carried me comfortably through an evening and overnight stretch, which was especially appreciated during the outage. If I had to point out a downside, it would be the weight. Even with the wheel kit, maneuvering it across uneven ground takes a bit of strength. Once it's in place, though, it's rock-solid. Overall, the Generac GP5500 is a reliable, well-designed generator that delivers exactly what you need during an outage or for demanding projects. It's straightforward, dependable, and built to last—qualities that matter most when you're relying on backup power.

Great generator

[This review was collected as part of a promotion.] I recently got this Generac Power Systems GP5500 Single Fuel 50 ST generator and am very pleased with it so far. It is very easy to operate, especially with turning it on. It provides very reliable power throughout the time that I had it on. It also is easy to store as it's not too big.

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.
