Firman Generators

About Firman Power Equipment

Founded in 1999 and headquartered in Peoria, Arizona, Firman Power Equipment has spent more than two decades engineering portable power solutions built to perform when it matters most. Whether you're managing a worksite, preparing for a storm outage, hitting the campground, or tailgating before the big game, Firman's lineup is designed to deliver dependable wattage across a wide range of real-world conditions.

What sets Firman apart in a crowded market is its focus on engineering integrity combined with practical usability. The brand's generators are built with larger fuel tanks and optimized for longer run times, so you're not constantly refueling in the middle of a project or an outage. Their engines are also engineered to handle variable loads, making them equally at home powering sensitive electronics as they are running power tools.

Shop Generators Built for Every Application

At the heart of the Firman lineup are its shop generators — a versatile family of portable units that spans everything from compact inverter models ideal for RV travel to high-output conventional generators capable of powering an entire workshop or acting as a whole-home backup solution. Firman offers both gas-powered and dual-fuel configurations, giving users flexibility at the pump. Many models are CARB and EPA compliant, broadening their usability across all 50 states.

Firman generators are also known for their thoughtful design touches: integrated fuel shutoff valves that help preserve carburetor life, covered outlets to shield connections from the elements, and low-oil shutoff protection to prevent engine damage. These aren't afterthoughts — they're baked into the engineering from the ground up.

Maximize Output with Parallel Kits

For users who need more power than a single inverter unit can provide, Firman's portable generator parallel kits offer a clever and scalable solution. By linking two compatible Firman inverter generators together, you can effectively double — or in some configurations, even triple — your available power output from a single combined outlet. These kits are exclusive to the Firman inverter family and are designed to work across different wattage models, so you can mix and match units as your power needs evolve. Built-in LED indicator lights and integrated outlet covers make setup straightforward even in low-light or dusty conditions.

Protect Your Investment with Generator Covers

A quality generator is a long-term investment, and Firman's generator covers are designed to protect that investment between uses. Purpose-built to fit Firman's generator models, these covers shield against moisture, dust, UV rays, and debris — the common culprits of premature wear when equipment sits in storage or on a trailer between jobs. Pairing a cover with your generator is one of the simplest ways to extend its service life.

A Brand Built on Reliability

Firman's reputation has been earned through consistent product performance and a commitment to standing behind what they sell. Their product range of nearly 30 SKUs reflects a deliberate focus: rather than trying to be everything to everyone, Firman concentrates on doing portable power equipment exceptionally well. For contractors, outdoor enthusiasts, emergency preparedness households, and RV travelers alike, Firman Power Equipment remains one of the most trusted names in the portable generator space.
