| Summary | The DuroMax XP5500HX is a 4,500-watt dual-fuel generator built for homeowners, job sites, and outdoor events. Running on either gasoline or propane, it delivers 5,500 peak watts at startup, enough to power refrigerators, air conditioning units, power tools, and multiple devices simultaneously. The dual-fuel design eliminates fuel sourcing constraints. At 25% load on gasoline, the unit runs for 19 hours before refueling, stretching a single tank across an entire workday or overnight camping trip. This runtime advantage makes it practical for extended outages or remote projects where frequent refueling would interrupt operations. | The DuroStar DS13000MXT is a 10,500-watt tri-fuel generator built for high-demand applications. Its tri-fuel capability (gasoline, propane, natural gas) and 13,000-watt starting capacity make it suitable for whole-house backup, RV power, and job-site work where fuel supply flexibility matters. |
