I purchased the 3500 IO back in 2020 in Texas. To date I have 7558.7 hours on the unit, it went through the Big Freeze in Texas, kept my neighbors homes heated during power outages. This unit has had the oil changed every 250 hrs (30W), Lucas upper cylinder gas additive occasionally, a new pull cord at 5800 hrs and a yearly plug change. I recommend this unit for all your uses up to 25 amps, it hasn't let me down. Great unit

I bought the GP2500i new a the beginning of December 2021 to provide some backup power if the electricity went out. I wasn't looking for a home backup- just to charge cellphones, led lights, run a single 1500W heater, power the fridge or freezer now and then to keep things from spoiling. From the unit's initial start-up, it took 5+ pulls to get it started. Successive starts were the same. 8-10 pulls to get it to start. Fresh fuel, 90+ Octane, no difference. From other reviewers on other websites, this seems to be a problem with this unit. However, I saw a post from a reviewer on another website with the same problem and he suggested 5-6 slow pulls with the unit set on Run, flip to Choke and then quick tugs to start. I tried his suggestion and it worked- 6 slow pulls followed by 3 actual quick pulls and it started and ran with no problems. I then ran it 20 min with 3/4 load. Stopped it for 5 mins to add fuel and it restarted on Run with 1 pull. This is with 60 day old, 91 octane gas treated for ethanol and storage protection. I would give the unit 5 stars if it started better. Other than that, it's a a great value for the money for the usable wattage it has. I hope this information is helpful.

Nice size, unbelievably quiet. I have a Genrac Home Standby generator and have had great luck with it so hoping for the same with the portable. I wish 'RV Ready' meant it had a 30A RV plug instead of 30LR5 Twistlock or at least make it an option to eliminate the need for an adapter. Wish there was a wheel kit, cover, & other accessories available for this unit.

Have this on our bowfishing boat pulling 12 100 watt leds. It's super quiet and very reliable. Only flaw I have found is the pull cord has a deep fray in it after one night. Will be going through warranty to get it replaced. Great product and easy maintenance!

I have had several carb issues. I worked where we sold Generac generators, and always spoke highly of them. I owned a GP5500 prior w/ few problems. I always kept ethanol free gas or gas w/ Stabil in my IQ3500 . Which purchased 9/2019. I had one carb replacement a year ago ,after a month wait for parts from Generac. It would start but not run and the ECO setting would shutter and shut the engine off. Now it is repeating problems, after only being run on ethanol gas for less than 1 hour. We used it to run the 13.5K A/C or to run heater fan and charge RV batteries. We were able to do one or the other at a time. It was never able to pull the 25 Amp specs.

I am from Puerto Rico, 69 days with out power and counting. This product with 1.2 gas tank, runs 10.5 ours , moving 1 fridge, 3 fans, lights, tv, Directv box, charging cel. plus computers. Is quiet an very easy tu use, i am looking to buy another one and the parallel kit. This is a nice product .

I purchased back in February of 2021 after a few days of a hard freeze in Oregon. I added as a 2nd generator for all around use. Finally took out of box (11/2022) LOL! All prepped up. Not too bad! Generator is lightweight, started on third pull, quiet. So far so good. Future plans would be getting a 2nd one, with parallel kit. Generator will be great for home, outdoor activities. Ill test more and put a review back up.

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. 😑***

We have been using this Generac IQ3500 for over 300 hours now without issues. We camp on our houseboat and instead of using the onboard generator that uses 1.6 Gal/Hr, we have a 30A twist lock into the boat to run all of the 110v. It generally runs 12-16 hours depending on load. Its super quiet in Eco mode and isn't very loud running full open. This has allowed us to extend our camping time and save money in gas to run everything except the 220V HVAC! I am thoroughly impressed with this generator. The onboard display center shows me hours, gas percentages, load, and estimated time. It has made it easy to keep up on maintenance for oil changes, spark plug and checking air filter/spark arrest filter. Would recommend this to anybody that is looking for clean power to camp, run power tools, microwave, or anything in the 30a and below range.

I have used this for power loss during a hurricane, tailgating, and camping. This unit starts every time with little to no effort. It is very quiet and it is strong. During the last hurricane I ran my TV, router, cable box, fans, and lights with this bad boy! I highly recommend it.
