An Overview on Firman Generators

Firman is trusted Chinese Company that specializes in making portable generators.  Unfortunately, anything made in China is associated with poor quality & all crappy. Luckily that’s not the case with Firman gensets.

Even though the company is based in China, its products are high quality and efficient and available at competitive prices.

How does Firman Generators compare with other brands?

Compared with other brands based in the USA, Firman gensets are affordable. Additionally, the company surpasses quality checks from regulators in China and here in the US.

In addition, the company has partnered with giant brands like Kohler to help high design quality and affordable generators and other mechanical products. This partnership saw a spike in Firman generator sales in over 10 million units. (Source)

In other words, Firman generators are powered by Kohler engines. For this reason, consumers have trusted this brand thanks to the “under the hood” improved engine performance by Kohler.
