The FIRMAN WH03342 is a versatile dual-fuel portable generator delivering 3,300 running watts and 4,125 starting watts on gasoline, with propane compatibility for flexible power options. Part of the Whisper Dual Fuel Generator Series, it operates quietly at 58dB—below National Park noise standards—and is RV-ready, making it an ideal choice for camping, tailgating, and outdoor recreational activities.
