Great generator for the price!

I recently purchased a Generac 3300i inverter generator for my camper, and I couldn't be happier with it. It's quiet, efficient, and easy to start, making it perfect for camping trips. It's lightweight and portable, so loading it in and out of the camper is no hassle. Overall, an excellent generator for the price—reliable, well-built, and great peace of mind when I'm off the grid.

Worked as advertised. Saved my food supply!

Used it twice now for neighborhood wide power outages. It has enough power to keep a refrigerator, freezer and some electronics going. For the first outage I had charged the battery and it started with the electric start. For the next outage, battery wasn't charged enough. However, the pull start worked easy on the first try.

Great portable Inverter/generator

I'm very pleased with the purchase of this model Generac Inverter. Really like the dual fuel operation and its low noise level. The other features that did NOT disappoint is its mobility to move around with the clever pull up handle, makes it very easy to maneuver as I'm a senior citizen. Also, pleased with having both the electric start and pull start option should the battery get weak/fail. I purchased this to have an emergency backup for electric to our home in case we lose power during storms. Didn't want to spend $12K - 15K for a whole home generator system. This unit will run a full circuit in our home along with the gas furnace/blower. I'd give the 5 Stars if it weren't for the battery hookup experience when I first received this unit. When I hooked up the battery it wouldn't work, however pull start worked fine and unit ran fine. I read through the manual, and everything was hooked properly to the battery. I made 2 calls to the Generac 24/7 hotline/support and they were -0- help. Checked the battery, figured it was bad, but to my surprise it was good. Next, check the wiring leads to the battery from the unit. Heck, there was an inline bypass on both Positive & Negative battery leads. Took 5 seconds to switch both. Smart idea by Generac to keep battery from draining until units are sold to a customer. BUT, C'mon Generac, put this info in your User Manual or attach note to battery leads and make your hotline phone service people know!

At 105 lbs. HARD for 89 year old to lift out of

Generator is quiet and started on 3rd pullstart. Instruction misleading on electric start! Shows how to hook battery at battery studs! Cost me $20 to find out line behind battery was unplugged! Already hooked to fully charged battery!! Quietly does job using very little gas, haven't tried LP yet. WELL satisfied with it! Used to trim all my hedges about 4 hours, some 150 ft from a plug in! BLESSINGS!!!

I like this iq3500 except.....

Seems like a great product but the motor started surging after the first hour of usage. I suppose there is a plugged orfice of some sort in the carburetor but I don’t really want to take it off and clean it. The fuel filter should have taken care of this issue. ??

Excellent and can be better.

I am a event rental company owner. We rent generators for many different applications. Purchased us to run our restroom trailers which have RV generators. What we really liked about it is that one person could move it. It is very quiet. We would love to see this with an EFI option.

Great generator

Bought for backup when camping. Have had to use it this past year and it was great.very quiet! Only con is that it doesnt like it when refrigerator and ac are on together. Says overload. Simple fix... put refrigerator on gas and everything else runs fine. Recommended to a friend and he loves it as well.

very good generator once it was repaired

I ordered the generator on line. After receiving the generator, I followed the directions of setting up and preparing the generator for use. The unit started but did not produce any electricity. I called for Generac for assistance and was offered either return or bring it to a service store. The was the best option for me. After a 5 minute investigation by the service person it was determined that a plug next to the battery was unplugged during shipping. Once this plug was connected to the display screen, the unit worked and is working well after 65 months of starting and running on a monthly basis. Generac, it have viewed several reviews of this generator on line and it appears this is a common problem. Please correct this issue.

Product ok

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.

Used twice and issues- now prepping for storm and no luck

I purchased this generator two years ago I have since used twice, draining it regularly as well as running it as needed. 1- I recently tried to start and at first pull the recoil did not work. It took about 30 soft pulls and me walking away for it to retract. 2 - purging, I don’t know if this is normal but it purges when it ran and now it won’t run, cleaned the carb from sitting- even without fuel. And ran for 30 second then have to pull it again 3. Service, I just looked up and the closest service center for Generac is 60 Miles away. What are my options for warranty/repairs? I like this machine for the space saving and power aspect but I am not seeing that maybe I should have went with my gut as far as prior luck with the Red and White brands comparable model. Generac, Please Help!
