Portable gas powered energy on the go.

[This review was collected as part of a promotion.] This generator is more bang for its buck than I expected. A little pricey and definitely on the heavier side, that can be overlooked since It’s easy to set up, great for portable job work, and an awesome machine to power your appliances if there’s ever a power outage.

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.

Perfect peace of mind for backup power

[This review was collected as part of a promotion.] As we head into the winter months, I’m so grateful to have the Generac Power Systems GP5500 Single Fuel Portable Generator. Power outages are pretty common where I live, and having this gives me real peace of mind knowing I can keep our outdoor refrigerator running and save our perishables if we lose power. The generator itself is quite large, but that’s to be expected given its power and capacity — and setup was surprisingly easy with minimal...

Top of the line

[This review was collected as part of a promotion.] This generator is definitely top tiered! The wheels make it easy to be portable. Living in Florida where hurricane season is so unpredictable this generator is a must! The only downside is doesn’t have a 220volt outlet for wells. It’s quiet for generator and will come in handy when the power goes out.

Great product

[This review was collected as part of a promotion.] This generator is great, out of the box it started on the second pull, I used my electric chipper with it since there are no plugs anywhere near my garden in the back of my yard and it powered it great. Haven’t used in a power outage yet but when the time comes I’m sure it’ll work great. I used it on propane the first time and it’s amazing how easy it is to use on propane. I don’t plan to run gas in it unless I need the extra power, or I know I...

Easy, reliable portable generator

Would Recommend

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!!

Great Tri fuel generator

Would Recommend

I bought this to run my whole house in case of another hurricane and we should lose our electricity. I have natural gas and it works just fine starting my HVAC and all other electric items when hooked to my gas line.

Must Have!!

[This review was collected as part of a promotion.] Thank you so much for the opportunity to test out this generator! It was incredibly easy to use. I did need a bit of help setting it up since it’s quite heavy, but once we got it on the wheels, it was a breeze to move around. That feature alone makes it so convenient to take out of storage when it’s needed. The generator runs beautifully, and without jinxing myself, I’m actually looking forward to using it when the time comes. It has more than ...

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.

Dual-fuel, easy start, and reliably powers essent

[This review was collected as part of a promotion.] This generator has been a great backup for storms. I love that it runs on propane or regular gasoline.Having both options makes it so much easier when stores are crowded or one fuel is hard to find. It starts up quickly and is simple to use, even for someone who isn’t super technical. When our power went out last week, it kept the essentials running: fridge, lights, Wi-Fi/router, and a couple of other small items we needed. No hiccups, no fuss...

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 comf...

Works well for small things. Instructions are conf

[This review was collected as part of a promotion.] The generator works well for small things like camping or a few devices at a time. I wouldn’t use it for a whole house but it could handle my essentials if I needed it to. The set up is not intuitive and the instructions are horrible. They should definitely include clearer instructions and pictures or how to set up the device and how to operate it. It’s quite heavy but easy roll around once the wheels and handles are attached.
