| 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 RP6500 E is a 6500-watt gasoline generator built for residential backup and light commercial work. Its 8125-watt peak capacity means it can start large tools and appliances that draw high inrush current, then sustain 6500 watts of continuous power for multiple devices simultaneously. A 7.9-gallon fuel tank delivers 12 hours of runtime at 50% load, which translates to roughly one full workday or overnight backup without refueling. The gasoline engine is straightforward to maintain and refuel anywhere, making this unit practical for job sites, outdoor events, and emergency home power. |
