| 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 Ryobi RY904500 is a 3600-watt portable gasoline generator, delivering 4500 starting watts. It features a 212cc OHV engine, a 4-gallon fuel tank providing up to 10 hours of runtime at 50% load, and is RV-ready with a 120V 30A RV outlet. |
