| Summary | The DuroStar DS14000iX supplies up to 11,000 running watts for major household loads and demanding jobsite equipment. Gasoline and propane operation offer two fuel choices, while output below 3% THD suits sensitive electronics. Its 120/240V connections support high-demand equipment, and 12.5 hours at 50% load on gasoline reduces refueling interruptions. | The Genmax GM6250iET is a 5,500-watt tri-fuel inverter generator built for users who need substantial backup power without sacrificing electronics protection. Its 3% THD rating means it can safely power laptops, refrigerators, and air conditioning units simultaneously, while the tri-fuel capability lets owners switch between gasoline, propane, and natural gas depending on availability. This combination of clean power and fuel flexibility makes it a practical choice for RV owners, homeowners facing extended outages, and job sites where power quality matters as much as raw wattage. |
