Overview of the FIRMAN H03655 Dual Fuel Portable Generator

The FIRMAN H03655 Dual Fuel Portable Generator is a name you might want to remember when considering a reliable power supply solution. It provides a convenient and versatile option with its ability to run on either gasoline or propane. This flexibility is a game-changer for emergency situations, RV adventures, or when working in remote areas.

Dual Fuel Capability

The major highlight of this generator is its dual fuel capability. With the option to run on gasoline or propane, you can choose what’s most accessible for you. During times when one fuel type is scarce or expensive, having an alternative can be quite handy. Gasoline gives you 4550 starting watts and 3650 running watts, while propane offers 4100 starting watts and 3300 running watts. This dual option ensures you’re not left in the dark, literally and figuratively.

Reliable Power Output

Whether you’re powering appliances, tools, or devices, the FIRMAN H03655 delivers steady electricity without making you second guess its abilities. With 4550 watts at peak start and 3650 watts for continuous use on gasoline, you’d be comfortably set up to run most household essentials. On propane, it’s not far behind either. This reliability makes it incredibly beneficial for home use or outdoor activities.

Performance and Usage

The design and technology behind the FIRMAN H03655 make it efficient for a wide range of applications. From camping trips to unexpected power outages at home, having this generator means you’re prepared.

Extended Runtime and Quiet Operation

Thanks to its 5-gallon fuel tank, the generator offers a substantial 14 hours of runtime at a 50% load. This means less frequency in refueling, giving you more time to focus on your activities without frequent interruptions. Additionally, operating at a low 67 dB, the generator is relatively quiet. No need to worry about disturbing your neighbors or the peaceful environment you might want during a camping trip.

Advanced Safety Features

Safety is undeniably paramount, especially when dealing with power equipment. FIRMAN’s built-in CO Alert Sensor is a thoughtful feature that automatically shuts down the generator once it detects unsafe levels of carbon monoxide. This gives you one less thing to worry about, especially when using the generator indoors or in areas where ventilation is limited.
