I'm sold on this generator

[This review was collected as part of a promotion.] If you want a generator that's strong, reliable, and not hard to figure out, the Generac GP5500 is a great choice. I was scared of this generator at first.  I am glad to have it for power outages and outdoor use, and it really delivered.  With a bit of help I was able to get it up and running.  Let's talk about the pros and cons and why it may be a good choice for you.  Pros     •    Plenty of power for the essentials — fridge, freezer, lights, fans, and small appliances.     •    Runs for hours on one tank.     •    Easy to start, even with the pull cord.     •    Sturdy build with wheels that make it easier to move.     •    Very dependable with the items I plugged into it.  Cons     •    It's heavy, so expect to roll it instead of lifting it.      •    A little loud — not sure what's normal.   If your power is out or you are outside and it works the noise doesn't matter.     •    Not the best for sensitive electronics like high-end computers.  Plug in the things you need the most during an outage.  Ease of Use Super simple. Just:     •    Add fuel     •    Check oil     •    Turn the switch     •    Start it That's all. Very beginner friendly.  I feel more secure knowing that I am prepared for an outage. I would recommend.

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.

Heavy duty power generator

[This review was collected as part of a promotion.] Generac power generator is an essential item. It's heavy duty and useful for periodic outages and is needed to keep my fridges running to keep my perishables items. I'm glad this one is dual fuel; gasoline and propane and that is much appreciated. It's fairly loud as expected of a power generator but we keep it far away with a long extension cord. Not an issue with noise. One of those things where you don't realize you need it until you really do. Definitely a must have if you are worried about keeping your items in the fridge fresh during power outages.

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.

Quality Generator

[This review was collected as part of a promotion.] The Generac 5500 generator was very simple and easy to put together. Adding oil and fuel easy as well. Start-up with manual startup was fairly easy. This unit also comes with a battery for an electric start which is pretty cool. The load can handle several small appliances such as a refrigerator, freezer and a TV or you can use it to run a single 220 volt HVAC system by itself. Moving the unit is a breeze as it comes with a handy handle that folds up and down for easy storage. Overall I highly recommend this unit and Generac is well known for their reliability and quality.

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.

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.
