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!

Great quality

The Generac generator that I purchased for our fiber splicing trailer has been great. We haven't had any issues thus far. It is easy to start and starts quickly even in cold weather. It is very quite compared to most others and the gas usage is very minimal. We are more than pleased with our Generac!

Best essential generator for living in the south

[This review was collected as part of a promotion.] This is honestly the best generator out there. It has all the essential features that a generator need, i live in the south so losing electric during the hurricane seasons is nothing new. The size is decent for an essential generator, not to mention its outstanding performance that help my refrigerator, can charge my electric car, microwave during the time of losing power. The design feature is phenomenal for its safety features. I highly recommend getting one.

Solid, well-made unit.

This generator is everything it claims to be. Easy to set-up, use and is reliable. I hooked it up to my home for a test-run the day after I received it. It started up instantly and powered the entire "critical function" sub-panel in my home (HVAC, water/well, freezers/refrigerators, water heater (gas), water softener, garage door, washer/dryer (gas), WIFI/network and critical lights/outlets). We built our home in 1998 (just prior to "Y2K", ha!) and included the sub-panel. I toyed with the idea of now installing a whole-home generator - but that would have been an $8-10K investment - this was <$1K. For the roughly one power outage we experience every 2-3 years, this is a good, economical solution.

Lower noise level than other generator and simple

[This review was collected as part of a promotion.] Very easy to assemble and to wheel around. Weighted over 200 lbs so it was a challenge to move the whole box. Works great and low noise. Full tank can go about 10 hrs of run time and I'm happy with that. Easy plug in and use.

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!

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!

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!

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.

Amazing Generator!

[This review was collected as part of a promotion.] Generac Power Systems GP4000 Dual Fuel 49 ST Portable Generator works amazingly well. We have power outages a lot where we live, especially in winter with all the rainstorms, so this has already come in handy a few times. It's a big generator and will work to power your essentials, but not so big you that it's ridiculously hard to get out of storage and get started. It's a pull start which is easy to use. I do wish it had a push start option as well, but it's not a dealbreaker. This gave us enough power to run essentials, like my espresso machine, recliner chair, lights, fridge, and chargers. It was easy to put together. And the wheels and handle make it super easy to maneuver around. I love that it's dual fuel. You can use either propane or gasoline. It's a nice generator and will be used for years to come.
