When you’re prepping for emergencies or looking for reliable backup power for your home or RV, the FIRMAN T04073 Tri-Fuel Portable Generator checks a lot of boxes. What makes this generator stand out is its versatility — it runs on gasoline, propane, or natural gas, so you have options depending on what fuel is available during an emergency or off-grid situation.
The FIRMAN T04073 generator delivers 4,000 running watts and 5,000 starting watts on gasoline, which is plenty for powering essential appliances, lights, and even tools during power outages. The tri-fuel capability is a game changer — if gas stations are empty, you can hook it up to propane tanks or a natural gas line. It’s also equipped with CO Alert Technology, which automatically shuts the unit down if carbon monoxide levels become unsafe — a critical safety feature for any generator.
This portable generator features an electric start for easy use, and it’s mounted on a sturdy frame with big wheels, so you can move it around without throwing out your back. It has multiple outlets, including 120V and 240V options, to handle different power needs whether you’re at home, on a job site, or out in the wilderness.
