## Customer Reviews

### ⭐⭐⭐⭐⭐ Love This Geni!!
*by C***L on May 22, 2025*

I absolutely love this geni. I live and travel in my van so this is one of my main sources for power. It works great and is not loud at all. Would highly recommend.

### ⭐⭐⭐⭐⭐ Strong portable generator
*by K***Y on May 23, 2025*

Great generator that’s efficient and decently quiet.Make sure to adjust the valves before firing the engine up for the first time, they come very tight from factory.

### ⭐⭐⭐⭐ A game changer.
*by D***N on June 2, 2025*

So far, so good. Love the duel fuel capabilities. A little harder to start on lp (6 - 8 pulls) than my old gasoline Champion (2 - 3 pulls), but the convenience of duel fuel more than makes up for it. Not too heavy, 50 60 lbs and two wheels/handle are a back saver. Much quieter and lighter than my Champion 3500 gas. Pleased with purchase.
