| Summary | The DuroMax XP15000HXT is a 12,000-watt tri-fuel generator built for stationary backup power and job site work. It runs on gasoline, propane, or natural gas, giving users flexibility to match fuel availability to their location. The 670cc OHV engine delivers 15,000 peak watts on startup, enough to handle the inrush demands of air conditioners, well pumps, and heavy power tools. At 12,000 running watts, it sustains refrigerators, furnaces, and multiple circuits simultaneously. This is a home-backup or construction-grade machine, not a portable camping unit. | The Ford FG18KVTWTCO is a 14,500-watt tri-fuel generator built on a 713cc Ducar V-Twin engine. It runs on gasoline, propane, or natural gas, letting users switch fuels based on availability and storage constraints. The 18,000-watt starting capacity handles motor inrush loads for air compressors, welders, and heavy construction equipment. This is a stationary workhorse for whole-house backup and jobsite power, not a grab-and-go unit. |
