| 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 Energizer eZV3500P is a 3,000-watt inverter generator built for users who need portable power without sacrificing convenience. At 3,000 running watts, this unit can power a refrigerator, microwave, and several power tools simultaneously. The 3,500-watt peak capacity handles the startup surge of air conditioning units and compressors. Gasoline fuel means no special storage concerns and easy refueling at any gas station.
The eZV3500P targets outdoor enthusiasts and homeowners who value flexibility in how they start the generator. Three starting options—recoil, electric, and remote—mean you can start it by hand, press a button on the unit, or trigger it from 100 feet away with the included key fob. The inverter technology protects laptops, phones, and other sensitive electronics from voltage spikes. A 3-year warranty covers defects across the generator's core components. |
