Tri-Fuel Generators
Tri-fuel units add natural gas to the gasoline-and-propane pairing. If your house already has a natural gas line, this is the closest a portable gets to a standby generator: unlimited runtime with no refuelling, for a fraction of what a permanently installed unit costs to buy and commission.
