10 Best Fuel Efficient Generator 2025 in the United States

The Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator is a powerful and versatile option for home backup power needs. It supports both gasoline and propane, offering flexibility depending on fuel availability. With 9500 running watts and 12500 peak watts on gasoline (8500 running watts and 11200 peak watts on propane), it's capable of handling substantial loads, making it suitable for residential use during power outages or emergencies.

The generator features a remote electric start and a transfer switch ready design, adding convenience for users who want easy operations and seamless power transitions. It also comes with multiple protected outlets, including standard household receptacles and RV-ready outlets, enhancing its usability for various applications. The runtime of up to 12 hours on a 6.6-gallon fuel tank is quite practical, though fuel efficiency might vary depending on the load.

The built-in VFT display provides real-time updates on voltage output, frequency, and lifetime hours, which is helpful for monitoring performance. However, the generator's weight of 210 pounds could be a drawback for those seeking high portability, despite being labeled as portable. Additionally, the noise level is not specified, but generators of this size typically produce a considerable amount of noise, which could be a concern for some users. While it doesn’t include inverter technology, which is essential for sensitive electronics, it’s an excellent choice for general home backup with robust power output and dual fuel capability.

The DuroMax XP13000EH Dual Fuel Portable Generator is a powerful option with a peak wattage of 13,000 watts, which makes it suitable for home backup during power outages or for use at job sites. It runs on either gasoline or propane, giving you flexibility in fuel choice. The electric start and user-friendly interface make it easy to operate, and it includes a 50-amp outlet for high-power needs.

Its copper windings and robust build ensure durability and longevity, even under heavy use and harsh weather conditions. The generator is portable with no-flat tires, but at 234 pounds, it is quite heavy, which might make moving it around challenging for some users.

Despite some drawbacks, the dual fuel capability, sturdy construction, and high power output make this generator a reliable choice for those needing a versatile and powerful backup power source.

It runs on both gasoline and propane, which can be handy depending on what fuel is more available or economical for you. With 13,500 peak watts and 10,500 running watts on gasoline, it can handle heavy loads like multiple appliances or power tools comfortably. On propane, the peak wattage is a bit lower but still substantial.

One of the standout features is its runtime—up to 19 hours on a full 9.5-gallon tank, which means it can keep your essentials running for a long stretch without needing a refill. It also comes with a remote electric start, making it easier to operate, plus safety features like automatic low oil shutdown and carbon monoxide sensors.

In terms of portability, it weighs about 230 pounds, so it’s not lightweight and will need some effort or wheels to move around, which might be a drawback if you want something more mobile. It has multiple outlets, including ones ready for RV and transfer switches, adding to its versatility. This Westinghouse model fits well if you want a powerful, dual-fuel generator with long runtime and convenient features for home backup use. Keep in mind it’s fairly heavy and lacks inverter technology, so it won’t provide the super clean power that sensitive electronics might require.
