GOOD PERFORMANCE, ALWAYS STARTS

Have powered this up 7 times, lit up the house twice, dependable.... but needs nose abatement technologies applied with off-the-shelf equip. to reduce the decibels.

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!

Overall, very good quality and features.

Just bought this a month ago and haven't had the need to use it yet. But I did have to assemble the handle, wheels, add oil and gas and start it. My review is solely based on that. The wheels were relatively easy to assemble, keeping in mind that the machine is heavy and you will need to lift it on blocks, or use a helper. They give you a perfectly shaped funnel to add the oil. Don't lose it. The handles are easy to install and conveniently fold down when not in use. They make it very easy to roll around on the two wheels. You also need to connect the battery wires, which they don't explain very well. Remember Red is positive, Black is negative. My only gripe is with the gas tank cover, though. It is very large, and very low profile, and it is in a sunken area of the tank. It is very difficult to get a grip on it to remove as it is also very tight. Why did they make it like this? I've never had any machine have a cap like this. It does have a convenient fuel level bubble. The gas tank is 8 gallons, not just 5 like my older model. It is rated at a continues 8KW, although the 240V 4-prong cable that connects to the breaker panel is only capable of carrying 7.2KW. You need to use the 2 120V outlets to get a total of 8KW. Keep in mind that the battery does not get recharged by running the engine. You have to use the included wall charger. Although, a single start is not going to use much power, so you don't need to worry too much about always keeping the wall charger connected. But definitely charge it fully when it is new. It has picture-based instructions on the frame. But they aren't very useful as they pictures are too small to figure out what they are saying. Remember to turn the fuel shutoff to ON and set the choke to ON when starting it.

Easy to assemble and use

[This review was collected as part of a promotion.] Where to start! This thing is heavy! After reading the instructions assembly seemed easy enough! It was about 30 minutes for assembly. I like that it has wheels making i extremely easy to move. The handle locks in place to move it and unlocks to store it. We are in the Midwest in an old neighborhood that has consistent power outages. This will make those days so much less stressful! We added the oil and fuel. It had a gage to show how much fuel is in it. After connecting the battery it took a couple of tries to start, I am guessing allowing for the fuel to cycle through. It has a push start and a pull start. It tells you hw much run time it has which is really convenient. You just push the button to stop. It was not extremely loud I would say comparable to a lawn mower in way of noise. It has a consistent run time of 10 hours which is great we've never been without power quite that long! It has 4 outlets. This has a 30 amplifier fpe 240 volts with a gfi outlet.

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.

Works fine, but super-loud

In reality, I only used this for about 20 minutes when the power came back on. This replaces a very old generator that had half the power. Aside from it working well, I can certainly say this generator is deafeningly-loud. Keeping it outside means you typically won't be bothered by it, but it makes you wonder if they could have improved the muffler.

Perfect Camping Companion!

[This review was collected as part of a promotion.] This generator has been an absolute game-changer for my camping trips. It's made cooking and lighting up my campsite so much easier and more enjoyable. Whether I'm running a small cooktop, powering up lights, or charging gear, it handles everything smoothly without missing a beat. What I really love is that it's propane-powered — no need to lug around extra gas cans or deal with messy refueling. That alone makes it so much more convenient and travel-friendly. The setup is super simple, and it runs quietly compared to most generators I've used. It's lightweight, efficient, and perfect for anyone who enjoys spending time outdoors. For the price, this generator is absolutely worth it. It's reliable, comfortable to use, and ideal for an outdoorsy person like me who values both convenience and performance.

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.

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 enough power to keep all my essential appliances running during an outage. I really can't say enough good things about it!

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.
