10 Best Power Generators 2025 in the United States

The DuroMax XP15000HX is a powerful portable generator delivering up to 15,000 watts of starting power and 12,000 watts running power, making it a strong choice for whole-home backup during outages or heavy-duty use at job sites. One of its standout features is dual fuel capability—it runs on gasoline or propane, giving you flexibility to choose based on cost, availability, and fuel shelf life. Propane also burns cleaner and is easier to store long-term. The generator includes a 670cc engine with durable copper windings designed to extend the unit’s lifespan. Starting the generator is easy with a push-button electric start and a remote control, which is handy if you need to power it on from a distance.

It has a comprehensive set of outlets including 120V household sockets and heavy-duty 240V outlets, plus it is transfer switch ready, allowing safe connection to home electrical systems. Its digital display keeps you informed about voltage, frequency, run time, and maintenance needs, while a built-in carbon monoxide sensor enhances safety by shutting the unit off if dangerous fumes are detected. Though portable, at 345 pounds it’s relatively heavy, so moving it may require some effort despite the included wheels and handle. The 5-year warranty adds peace of mind for long-term use.

This generator is well-suited for homeowners looking to power essential appliances during blackouts, RV owners needing reliable power on the road, and professionals requiring a robust generator for work sites. It is a large and heavy unit, so portability has limits, but its power, fuel options, and safety features make it a solid choice for heavy-duty and whole-home power needs.
