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 Powerhorse s12500t is a versatile 12,500-watt tri-fuel portable generator equipped with electric start and CO shutdown features, suitable for various power needs.
