Can’t find a parts manual anywhere. I need to replace the side enclosure panel. Other than that it seems to be working fine. Just need to go camping and try it out

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

Would Recommend

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!!!

Great generator for the price!

Would Recommend

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!

Would Recommend

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 stor...

The inverter generator works as advertised. I thought it would start better than it does. It takes at least 4 pulls to get it started. My Briggs lawn mower starts on 1 pull and the generator takes 4 or more. Could be bettered engineered.

Hard cranking

Good product, takes at least 3 pulls to crank each time. Hard cranking only downside

I bought this well over a month ago for use if we lose electricity. Have set it up and started it but nothing else. I hope it works as an inurance policy and prevents us from loosing service. If that is the case, I am pleased I made the purchase. The electric start was a must and that was an important feature when making the purchase. If and when I use the generator, my overall rating could change.

Super disappointed

I bought this on Friday for our tailgate on Saturday. Put oil in it that came with it, filled it with ethanol free gas and never would start. After 3 hours of trying to get it to start we just gave up. Have never been more disappointed in purchasing a product as buying this portable generator. Ruined the entire tailgate
