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 Pulsar PGD105TiSCO is a 10,500-watt peak inverter generator that operates on tri-fuel options including gasoline, propane, and natural gas. It features a 458cc OHV engine, multiple starting methods, and is suitable for residential, outdoor, and work applications.
