| 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 Cat RP12000 E is a 12,000-watt gasoline generator built for job sites, construction crews, and homeowners who need sustained power for multiple heavy tools or appliances simultaneously. The 15,000-watt peak output handles startup surges from air compressors, circular saws, and welders without stalling. At 350 pounds, this is a stationary or semi-portable unit. It ships with a wheel kit, battery charger, and full tool set, meaning users can operate it immediately without additional purchases. |
