| Summary | The DuroMax XP15000HXT+ is a 12,000-watt tri-fuel generator built for serious backup power and job site work. Running on gasoline, propane, or natural gas, it delivers 15,000 peak watts and 12,000 running watts, enough to power multiple heavy loads simultaneously like refrigerators, air conditioners, and construction tools. The tri-fuel flexibility means users can choose the most available or cost-effective fuel source for their situation. This is a stationary workhorse, not a portable grab-and-go unit. At 237 pounds with a 29.5 x 28 x 26 inch footprint, it requires permanent placement or serious logistics to move. The included wheel kit helps, but this generator is built to stay put once deployed. | 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. |
