Great looking , quiet and affordable generator!

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. 😑***

Began positive

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.

This product let me down

I purchased your iq3500 in August of 2022 and used it to power my RV twice in less than a year . The Electric start quite working in June is 2023 (less than one year ) , I checked the battery it was good . Would not do anything, I assume the starter went bad . Then I pull started it , started fine first 2 times . The third time that I tried to pull start it the pull start rope broke . The unit is less than a year old and has only been pull started 3 times and the rope broke and starter quite working . Very disappointed with the quality, hopefully they honor their warranty.

Very quiet and easy to maintan

[This review was collected as part of a promotion.] I’ve been using the iQ3800 for home backup during storms and weekend RV trips—and it’s been outstanding. It kicks out 3,800 starting watts (3,100 running) on gas or 3,420/2,790 on propane, giving me flexibility when fuel is tight. Despite its power, it stays impressively quiet, so I can run it overnight without bothering the neighbors. Built with a rugged steel frame and protected outlets, it’s held up to bumps and rough handling, and the Eco‑Mode™ engine control delivers smooth, efficient performance under varying loads. I love the electric start (with manual backup) and the Smart CO™ shutoff for safety. Routine upkeep is a breeze thanks to tool‑free access to the oil fill and air filter. For reliable, low-noise power and minimal maintenance whenever and wherever I need it, the Generac iQ3800 has been a fantastic, peace-of-mind investment.

Sweet Little Gen!

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.

Excellent product. Better than Honda. More features.

The Generac IQ2000 generator out performs the Honda generator. I love everything about it. After looking on YouTube and the internet I decided to go with the Generac. Price is just right. I am a retired Firefighter and First Responder after 39 years. Used all types of generators in the fire service. Thank you again Generac for a great product. Will use the generator for my personal use during storms, etc.

Great looking unit

Still in the box, but it’s a very nice unit. Came well packed with clear instructions. Once I have a need for it, I know it will preform. General is a reliable brand

Very nice quality for the price

I was very impressed with the quality at this price range. Love this generator. The only ask is put a gas gauge say side linear window or tube showing gas level .
