What Customers Are Saying

The generator is well-built, easy to use, and provides good runtime and power output. Customers praise its quiet operation, convenient features like electric start, and its ability to power various household appliances and electronics during power outages. However, some customers have experienced issues with ignition, unexpected shutdowns, and the generator being underpowered for their needs. The quality of the plastic enclosure has also been a concern for a few customers. Overall, it may be a good option for light to medium-duty use, but potential buyers should carefully consider the product's capabilities and limitations.

POWER UP

Would Recommend

I 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.

Simple instructions on how to set up, really like the propane feature no need for messy gasoline.The noise levels were fine and the unit was light enough that I could load it easily into the back of my pickup for travel.

My 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 Recommend

The 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 Recommend

Bought 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.

The little Generator that could.

Would Recommend

Had a power outage due to high winds and ordered this from Lowes online, as it was the last of its kind in stock. Got it up and running about 10 minutes after pickup, and got my 2 fridges and upright freezer up and running on it asap, as it had been 8 hrs without power. Next up got the Mesh network up and running and then the 85" in the living room. Once the fridges and freezers settled in, set it to ECO mode and it idled down nicely and was just noticeable running inside. All this on a propane...

Lowe’s selling used generators as “new”
