Unleash Reliable Backup Power Whenever You Need It With The Firman H03651 Dual Fuel Portable Generator

This versatile powerhouse delivers an impressive 4550 starting watts and 3650 running watts, making it ideal for powering essential appliances during a power outage, running tools at a job site, or keeping your RV systems humming along on your next camping trip.

Firman H03651 Dual Fuel 4550W Portable Generator Features

Dual Fuel Technology for Unmatched Flexibility

The H03651 shines with its dual fuel capability, giving you the freedom to choose the fuel source that best suits your situation. Run it on readily available gasoline for quick starts and familiarity. But when portability and storage become priorities, the H03651 seamlessly switches to clean-burning propane. This lets you leverage the extended shelf life of propane and the ease of refilling from standard 20lb propane tanks (not included).

Enjoy Quiet Peace of Mind Without Sacrificing Power

Even with its impressive power output, the Firman H03651 prioritizes tranquility. The Whisper Series muffler effectively reduces noise levels to a mere 67 decibels, falling well below National Parks Service standards. This means you can enjoy the power you need without disturbing your surroundings, making it perfect for campsite use or powering your home during a blackout without disrupting the peace.

Enduring, Reliable Performance You Can Count On

The H03651 is engineered for rugged durability. Its 208cc Firman Max Pro Series engine boasts a cast iron sleeve for extended lifespan and reliable operation. The Phoenix Fat Head Block ensures efficient cooling, preventing overheating even during demanding use.

Easy Starting Gets You Powered Up in Seconds

Forget the hassle of manual pull starts. The H03651 features a convenient electric start system that gets you up and running with just the turn of a key. For those who prefer a traditional approach, a recoil start is also included, providing a dependable backup option.
