Would Recommend[This review was collected as part of a promotion.] "I pulled this generator out of my Trailer during a remodel. I’m definitely keeping it as an emergency backup for guests and power outages. It’s a beast whenever you throw a huge power demand at it, it delivers without skipping a beat."
From FIRMAN Power Equipment
Highly recommend
Would RecommendThis inverter generator is very quiet. Sitting right next to it in the garage and I can still have a conversation without yelling. Easy to start, easy to maintain, and not to heavy. Average person can pick it up and lift it. This runs my 26' camper A/C and other things just fine. No issues. I would highly recommend this generator invertor depending on what your looking to run.

POWER UP
Would RecommendI wanted the dual fuel mainly for the propane use. Pick up was quick and easy. Once I got it home I hooked up the propane and two pulls it was running. It's pretty quiet even under a load. Nice little generator just what I needed.

This is a complete power package.
Would RecommendMy family and I were in need of a new inverter generator for our 50A camper trailer. Separately purchased a 50A female to 30A male pigtail, unboxed, serviced and set up the generator. Pulled the choke, pressed start, and off she went. I was surprised by how quiet it was. I tested the various outlets for output and all checked good. Shut her down, made one last check on oil level, etc. A little on the heavy side for one old dude to lift over waist high into a truck bed, but doable. Once at the ...

Firman 4125 watt Dual Fuel
Would RecommendThe manufacturer has made this product mostly idiot proof. They provided easy picture instructions in paper form in English and Spanish and directly on the generator. They provide oil, a cover, and cords with the generator. I first thought it was a steep price until when I received it and was able to use it for my camper. This product is worth the price, and is well built. You can tell Firman has pride in their products.

Wouldn't start when I really needed it
Would Not RecommendBought this unit at Lowe's a few years ago. I liked that it was dual fuel. I always keep plenty of propane on hand for grills and griddles. When I got it home, I tested it with both gas and propane. Ran fine. Power is temporary off for the day so I pulled it out, hooked up the tank. Won't start.
Sorry to hear this happened—especially when you needed it most. That’s never the moment you want a generator deciding to take the day off.
