Out of the box

Purchased in early spring for summer camping. Did not use until December and first time running started right up. Let it warm up and would not run with choke off. Ran under load for approximately 8 hours and had no other issues. The problem is that it would have to be almost full choke to run. Took it in for repairs and was told the carburetor needed to be replaced. Contacted manufacturer after service center stated is was not covered under warranty and the manufacturer said same thing. I am replacing the carburetor and hope there will be no further issues. Love the product, not happy with support.

Ultimate Test

Another one living in Puerto Rico experiencing almost 3-month without power. Bought the Gernerac Inverter and started on first pull. Verry friendly user and easy to install. The best decision given (i) the portability of the product, (ii) the savings/eddiciency and (iii) its simplicity. Totally recommended.

Good product without much support or info

First off I won this in a raffle, so there is nothing to complain about. However I would like to point out a few things that I feel could be done better by Generac. First off, there are no break in instructions included with the generator. I assume every small engine needs a break in period so I had to look this up myself and perform it. Secondly, why no wheel kit? Yes it’s kinda light but would a wheel kit be hard to make or sell? Sure would be handy, so I’ll have to make one myself. Third, it was quite difficult to find where to register the warranty. You really have to search to find it.

great product

Used it while deer hunting last fall. Nice and quiet. Only problem was that the left side of the case was broken near the bottom. The box that the unit came in was in perfect shape when I opened it so I feel that the damage was done before it was placed in the box. Other than that I love the unit.

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.

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!!!

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.
