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!!!

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 stor...

Bought at Menards used for the first time 30 days after and it would shut down when any load was applied, had to get it serviced not replaced. Works fine now but would have preferred a new one not waiting 4 weeks fir a repair

Generac would not start
Ordered Generac 3500 GP manual start. Was exited to get it going . Topped it off with fuel and oil as recommended. Pulled the handle about 100times . Could never get it started. Opened the side panel where the oil plug is located . Didnt see anything unusual . Was about to give up box it and return it to Lowe’s when I decided to open the panel from the pull side . Just looked in there to see if something was off or anything I could see. Lo and behold I see a quick attachment cable was disconnect...
