The Story
The FIRMAN P08004 Portable Generator delivers serious 120/240V power for home backup, storm preparation, and demanding jobsite applications. With 10,000 starting watts and 8,000 running watts, this 30/50-amp gas generator is built to power large appliances, essential home circuits, RV setups, and heavy-duty tools with confidence.
Powered by a robust 439cc FIRMAN engine with a durable cast iron sleeve, the P08004 is engineered for reliable performance under load. The 8-gallon fuel tank provides up to 12 hours of runtime at 50% load, giving you extended operation during outages or long workdays. Multiple starting options—recoil, electric, and remote start—make powering up fast and convenient in any situation.
The multi-feature control panel includes covered outlets for added protection and versatile connection options: (1) 5-20R 120V 20A duplex outlet for household tools and appliances, (1) L5-30R 120V 30A twist-lock outlet, (1) L14-30R 120/240V 30A twist-lock outlet, and (1) 14-50R 120/240V 50A outlet (33.3A/240V/8000W) for high-capacity transfer switches and large equipment.
Low oil shutoff protection helps safeguard the engine, while the built-in fuel gauge keeps you informed. Every P08004 comes ready to go with engine oil, oil funnel, remote control with holder, spark plug wrench, and a 10mm x 12mm double open-ended wrench included in the box.
Built for performance. Designed for reliability. Ready when you need it.
