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.

The DuroMax XP11000iH is a robust dual fuel generator delivering 11,000 peak watts and 9,000 running watts, making it suitable for heavy-duty needs like home backup, job sites, or RV power.

It has a large 7.1-gallon tank which supports long run times, reducing the frequency of refueling. Starting is easy with a remote electric start, and it also includes an automatic transfer switch ready outlet for seamless connection to home systems.

This generator uses inverter technology, providing clean and stable power safe for sensitive electronics such as computers and TVs. Safety features like a CO sensor automatically shut it down if unsafe carbon monoxide levels are detected, which is a big plus. It weighs 216 pounds, so while portable, it may be difficult for one person to move without assistance. With multiple outlets and a digital display for monitoring, the unit offers convenience and control. The low oil shutoff feature helps protect the engine from damage. You can even connect two units in parallel for double the power, though the parallel kit is sold separately. It complies with EPA and CARB standards, ensuring it meets environmental regulations.

Its weight and size might limit portability for some users, and noise can be a factor in quiet settings. The price and complexity might be more than needed for casual or light-duty use. For those needing reliable, flexible, and powerful backup or portable power, the DuroMax XP11000iH is a strong contender with useful safety and convenience features.

The inclusion of a CO sensor and automatic shut off is a significant safety advantage, protecting users from hazardous emissions.

It does come with some drawbacks. The noise level can be on the higher side, which might be bothersome in quiet neighborhoods. Also, being gas-powered, it requires regular maintenance and fuel management, which could be inconvenient for some users. Additionally, while the generator is designed to be user-friendly with plug-and-play features, it may still be a bit overwhelming for those unfamiliar with using generators. This generator is ideal for homeowners who want a dependable power source for residential use, especially during emergencies. It's also suitable for outdoor events, but you'll need to consider the noise and size aspects before committing. With a solid warranty and support network, Westinghouse provides reassurance in case of any issues.
