Purchased 2 of these portable generators for our RV they are very quite and run great. We like the features on the gas gage and how many hours left till empty are awesome no longer waiting till they run out to see to put in more gas. Takes out the guessing game, also like the feature on how much power your consuming as well.

After doing lots of research online I chose this generac model and have not been disappointed! It is incredibly quiet even under load. The efficiency mode is a nice option for lighter loads to conserve fuel. The only issue I have is the generator is a bit heavy for one person but can be managed if necessary. A wheel kit would make it about perfect if one were available. The electric start is a great feature and pull start is not difficult if needed. Started right up out of the box and have had no issues, it runs the ac unit on my 32 foot travel trailer with no problem. Highly recommend this model, quality well built generator as the ne would expect from Generac.

We are the owners of J&G's Place 2B, a bed and breakfast in Ripon, WI. A massive storm hit Ripon and surrounding areas on July 28, 2021 and shortly after midnight we lost power during the middle of EAA Airventure, when Oshkosh hosts the world's largest airshow for a week. This is also the busiest week of the year for our business. A requirement for a bed & breakfast license is that you MUST HAVE HOT WATER, otherwise you are to close immediately. We were looking at a couple of thousand of dollars of lost revenue if we could not stay open. I got out our Generac 3500IO for the first time, a bit worried about making it work. It took all of ten minutes to set up (put in oil and gas and run our extension cords) and it was easy to use (started on the first pull) and kept our business humming and our guests happy for the two days it took the electrical crews to restore service. It already comes with the oil you need for the oil reservoir. Took about half of the included bottle to get it to the right level. It was nice not having to hunt down a bottle of oil. Ran all night and more on one tank of gas, so it is efficient. Especially impressed with how quietly it runs. One thing I would love to see: is there a wheel & handle kit available for this model, and a rain canopy/cover I could buy so it is easier to transport and also be able to use it in the rain? Thank you, Generac, for saving our business. Best, -Jason & Giselle PS: Using two extension cords plugged into the two outlets on the generator, we ran two refrigerators, a chest freezer, a natural gas hot water heater, two lamps, and 2 CPAP units, and had some Watts to spare, plus we charged phones and tablets through the 2 USB ports on the back of the generator. We buy the most energy efficient appliances available, which means we were able to get by with a much smaller and less expensive portable generator that will fit in the back seat of a Toyota Corolla when it is boxed up, which perfectly describes the 3500IO. We recommend it highly!

Overall nice looking took 3 units to get a good one 1st one display not working properly, 2nd unit the first ones replacement exhaust plastic broken, corner of metal not in plastic looking on the inside wire loom was wore though and date codes were 2 years old, 3rd unit good so far. but used less then an hour.

[This review was collected as part of a promotion.] I was lucky enough to receive the Generac Dual Fuel Portable Generator as a gift from Influenster for review, and while we haven’t needed to put it to the test yet (thankfully, no power outages!), I can already tell this is a game-changer for our home. From the moment it arrived, I was impressed. The generator feels incredibly well-built — solid, durable, and thoughtfully designed. The dual fuel capability was one of the first features that caught my attention; being able to choose between gasoline and propane adds so much flexibility and peace of mind, especially during emergencies when fuel availability can be unpredictable. Setting it up was straightforward. The instructions were clear, and the controls are easy to understand, even for someone who isn’t super experienced with generators. I also love that it comes with a mobility kit, making it much easier to move into place if and when we need it. While we haven’t had the chance to run it yet, just knowing we have a reliable, high-powered backup ready to go is a huge comfort. I truly appreciate that Influenster gave us the opportunity to be ready for whatever comes our way. Can’t wait to update this review once we officially put the Generac to work — but for now, it’s getting five stars just for the quality, design, and peace of mind it brings.

I purchased this on 10/05/2019. I bought this to run a couple of rental houses when the power goes out, instead of hauling my big one around. I have no problems getting it started but after 15 minutes of running, it stops on its own. I'm just running it without being connected to anything. I'm not sure how this is going to work when the power goes out and I need to get electricity to power on. Time will tell. The book says check oil but oil was new and just added. I can't really say if I can recommend this at this time.

Purchased this generator at the last second while on a camping trip. Noise level was next to nothing....had the unit sitting 10 feet from three of having a conversation and didn't notice it was there. Very simple to start and fuel efficiency was excellent.

Researched inverter generators on YouTube for hours to find the perfect unit to power my camper at unserved sites. Narrowed my choice down to the Honda EU 3000is or the Generac iQ 3500, but it was the Generac’s cost that made it the easy decision! For being equally (or possibly even more) quiet, 20lbs lighter and having nicer features such as a keyless starting switch, automatic choke, and a display screen for monitoring voltage output and run time to gauge oil changes it knocked it out of the park!! Generac…please make a nice fitted storage cover for this generator! It is a beautiful unit and deserves one! Only one complaint is that the generator started surging right out of the box brand new. I carefully added the included engine oil to the correct level and poured in clean, fresh gas but it needed a carburetor cleaning probably from having residual gas sitting in the carburetor or float bowl during product testing before packaging and sitting in a warehouse for 2 years until I purchased it. Service was covered under warranty, it was just the inconvenience of having to take a brand new unit in and the frustration of fiddling with it myself for 4 hours previous to the service. (I removed and cleaned the carburetor personally, the service centre only removed the float bowl as people are lazy now). ***Be mechanically inclined if you buy this generator. Good service doesnt’ exist anymore. No one will help you. 😑***

I have owned a Generac pressure washer for more than 20 years, and previously owned a whole house generator, I have/had great service from both. Decided to purchase a small stand by generator - GP3300i. I have ran for a few hours and very happy. Quieter than I expected and does what I need.

have not used it yet. but used another one like it and liked it
