Firman Generators Review

Firman may not be as popular as other household generator brands, such as Yamaha, but after thoroughly analyzing their generators’ features and what current users have to say, we feel that Firman generators are quite underrated.

This Firman generator review highlights all there is to know about this brand, including its significant pros and cons. As usual, our review team also hand-picked a couple of the best Firman generators that are worth checking out.

Distinguishing Features of Firman Generators

  • Power range– Firman portable generators have a wattage range of between 1700w and 10000w.
  • Extra-large fuel tanks– most Firman generators offer 9-14-hour runtimes thanks to their large fuel tanks.
  • Wheelbarrow design– most Firman Hybrid series generators have a wheelbarrow design that boosts their maneuverability.
  • Single, dual, and tri-fuel options– Firman hybrid generators offer you a choice of up to 3 fuel types: gasoline, natural gas, and propane gas.
  • Start type– in line with the advancements in generator technology, several Firman generators have electric and remote start options in addition to recoil.


Firman generators are relatively inexpensive across all categories compared to most of their competitors. Well, some cost slightly over a grand, but these are packed with premium features and systems, including inverter technology and multiple fuel and starting options. On average, Firman portable generators cost around $600. The cheapest model goes for about $260, while the most expensive one asks around $1200.

Are Firman Generators Good?

Short answer: Yes.

Firman is among the least known Asian generator brands among the Westerners. Therefore, it’s easy to understand if you’re skeptical about spending your money on these generators. But it’s important to note that this is a fairly new brand established in 2001. This could partly explain why Firman is still new to most of us.

Its newness aside, Firman generators are loaded with fantastic features and technologies, and most of them rank highly in terms of reliability. In fact, we expect this brand to rival major giants, including Honda, Yamaha, and Dewalt, in the near future.

Notably, like other Chinese generator brands, Firman has a few models that tend to fade away pretty fast. So, keep your guard while comparing the different units. A good way of doing this is considering what previous buyers have to say about each generator before committing. Also, you can check our Firman generator reviews to find out which are their most-recommended models.

About Firman Company

Firman is one of the brands under the SUMEC Group. SUMEC itself is a crucial member of SINOMACH (China National Machinery Industry Corporation). Firman brand was officially established in 2001, and this makes it a relatively new brand compared to others that were formed in the 1900s or earlier (think of Kohler, Hyundai, Generac, and Ford).

However, it’s important to note that Firman existed for years before 2001 only that it was manufacturing generators for private label brands, including Kohler and Ridgid. This could explain why it hasn’t been hard for their products to penetrate the market despite its seemingly late entrance. Actually, judging from the quality and reliability of its generators, we predict that this will be one of the most reputable generator brands in a couple of years.

  1. I purchased a firman w03083 model generator for camping from Home Depot(online of course). Was excitedly when it arrived. Followed the start up directions to the letter. Since it was almost a grand to buy. Started just fine, worked just fine. Didn’t run it for about a week and went to show it off to family members only to find out no matter what I did it would not start! Called for days to the customer service department in Arizona. Was on hold for almost an hour. Finally got authorization to drop it off at a repair place they picked! They had my new generator for three months!! Finally went to pick it up. Before leaving tried to start it. It would not start! So left it there for two more weeks. Finally it was fixed, started up and ran just fine. Took it home started it a few more times. Didn’t go camping in 2020 after that. Still haven’t used it for camping. Did end of season shut down per manual. Just went to start it up. No matter what I do it WON’T start! I would return it to Firman but they don’t have a store to do it. Now I have a $1000.00 generator that doesn’t work!
