The FIRMAN WT05571 Tri-Fuel Whisper Series Generator delivers versatile, dependable power with the freedom to run on gasoline, propane, or natural gas at the push of a button. Designed for RV use, camping, DIY projects, and home backup, this generator adapts to whatever the moment demands—without locking you into a single fuel source.
On gasoline, the WT05571 produces 6,850 starting watts and 5,500 running watts. Switch to propane for 6,250 starting watts and 5,000 running watts, or natural gas for 5,500 starting watts and 4,500 running watts, giving you reliable output no matter what fuel is available. Built into a compact 136.7 lb frame, it features an integrated wheel kit and handle for easy transport wherever power is needed.
Operating at just 67 dB, the WT05571 lives up to its Whisper Series name, making it ideal for campsites, RV parks, and residential use. Eco Mode improves fuel efficiency during lighter loads, while CO Alert technology automatically shuts the generator down if unsafe carbon monoxide levels are detected—adding an extra layer of safety during operation.
To handle a wide range of power needs, the WT05571 is equipped with a versatile outlet panel that includes a 120V 20A GFCI duplex (5-20R) for household devices, a 30A RV-ready TT-30R, a 30A 120/240V L14-30R, and a 50A 120/240V 14-50R outlet for higher-demand applications. USB-C fast charging and a 12V DC port round out the setup, making it easy to power modern electronics alongside larger equipment.
Quiet, adaptable, and built for real-world use, the FIRMAN WT05571 is a powerful tri-fuel solution you can rely on—at home, on the road, or off the grid.
The WT05571 comes with an engine oil bottle, an oil funnel, a tool kit, an LPG regulator, and a quick oil drain.
