| Summary | The DuroStar DS13000MXT is a 10,500-watt tri-fuel generator built for high-demand applications. Its tri-fuel capability (gasoline, propane, natural gas) and 13,000-watt starting capacity make it suitable for whole-house backup, RV power, and job-site work where fuel supply flexibility matters. | The Cat INV2000 is an 1800-watt inverter generator built for users who need portable, clean power without the noise. At 48.8 pounds and measuring 19.6 x 12.5 x 18.1 inches, this unit bridges the gap between lightweight portability and genuine load capacity. It runs on standard gasoline and produces less than 3% THD, meaning laptops, phones, and sensitive electronics stay safe from voltage spikes. The recoil start fires up quickly, and the 52 dBA noise level keeps it quiet enough for residential areas and campgrounds.
With 10 hours of runtime at 25% load and 6 hours at 50% load, users can power essential devices through a full day or night without refueling. The 1-gallon fuel tank and automatic low-oil shutdown mean less maintenance worry. This is a grab-and-go generator for camping, tailgating, emergency backup, and light outdoor work where portability matters as much as power. |
