| Summary | The DuroMax XP13000HXT is a 10,500-watt tri-fuel generator built around a 500cc OHV engine with cast iron sleeves. It runs on gasoline, propane, or natural gas, which means users can adapt to fuel availability rather than being locked into a single source. At 10,500 running watts, this unit crosses into heavy-duty territory. It can simultaneously power a central air unit, water heater, and multiple household circuits during an outage. For job sites, it handles compressors, circular saws, and angle grinders without strain. The tri-fuel flexibility also makes it valuable for users in regions where propane or natural gas may be cheaper or more accessible than gasoline during extended outages. | The Genmax GM15000ET is a 13,000-watt tri-fuel generator built for serious power demands. With 13,000 running watts and 15,000 starting watts, this unit can handle whole-house backup scenarios, including central air conditioning, refrigerators, well pumps, and multiple circuits running simultaneously. Because it runs on gasoline, propane, or natural gas, owners gain real flexibility during emergencies when one fuel source might be unavailable or during extended outages when tapping into a home natural gas line eliminates refueling trips entirely. |
