10 Best Dual Fuel Quiet Portable Generators 2025 in the United States

The Westinghouse 13500 Peak Watt Dual Fuel Portable Generator is a strong option for home backup power, offering a high peak wattage of 13,500W on gasoline and 12,500W on propane, enabling it to handle heavy loads like multiple appliances or tools simultaneously. It runs for up to 19 hours on a full 9.5-gallon gasoline tank, which supports extended outages. The dual-fuel capability (gasoline and propane) adds flexibility, so you’re not tied to just one type of fuel. Starting the generator is easy thanks to the remote electric start with a key fob, plus a manual recoil start is available as backup.

Safety is well covered with features like automatic low oil shutdown, carbon monoxide sensor, and GFCI outlets with protective covers, helping keep users and devices safe. The generator is built with a robust 500cc engine and includes useful extras such as a fuel gauge, hour meter, and USB port. At 230 pounds, it’s quite heavy, so while it is portable with wheels and a handle, it’s not something you’d want to move around frequently or alone. Being a large dual-fuel generator, it can be expected to produce more noise than smaller models, which might not be ideal for noise-sensitive environments.

The generator is transfer switch ready, making it convenient for home integration. It comes well-equipped with necessary accessories, and the 3-year warranty provides peace of mind. If you need a powerful, reliable backup generator with flexible fuel options and easy starting, this Westinghouse model fits well, especially for residential use where weight and noise are less of a concern.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a robust and versatile power source, ideal for residential use. With a power output of 9000 running watts and 11000 peak watts on gasoline, and slightly lower on propane, it offers ample power for most household needs. The dual-fuel capability is a significant advantage, allowing the use of either gasoline or propane, depending on availability and preference. The 9.8-gallon fuel tank provides up to 17 hours of runtime, which is impressive for extended use without frequent refueling.

The inclusion of both remote electric start and push-button start makes it user-friendly, especially for those who prefer convenience over manual recoil starting. Safety features like the CO sensor and low oil shutdown add an extra layer of protection, making it safer to operate. The unit comes with various accessories, including a remote, oil funnel, and parallel cables, which aid in setup and use.

On the downside, the generator is quite heavy, weighing in at 187.4 pounds, which may affect portability despite the wheels and handle. Noise levels are not explicitly mentioned, but as a powerful generator, it might be louder than smaller units. It’s also worth noting that while it is EPA compliant, it may not meet stricter regulations in all areas. The rotating digital display with information on fuel level, power output, and runtime adds to its convenience, allowing users to monitor its status easily. Lastly, the generator is backed by a 3-year limited warranty and a nationwide customer service network, which is reassuring for long-term support. This generator is highly recommended for those needing a reliable power source for residential use with the flexibility of dual fuel and advanced safety features.

The DuroMax XP13000HX Dual Fuel Portable Generator is a strong contender in the dual-fuel generator category, offering up to 13,000 watts of power, which is more than sufficient for running essential household appliances during power outages or storms. One of its standout features is the ability to operate on either gasoline or propane, giving users flexibility in fuel choice and enhancing efficiency. Propane, in particular, is known for being clean-burning and cost-effective.

This generator boasts a powerful 500cc engine and is built with all-copper windings for durability. The electric start feature simplifies operation, making it accessible for everyone, and the front-facing control panel allows for quick fuel type changes. Users will also appreciate the variety of output options, including multiple household outlets and a 50-amp outlet for transfer switch readiness.

On the portability front, although the generator weighs 245 pounds, it comes with wheels and a handle kit to assist with movement. Its compact design makes it suitable for residential use, but it may not be the best option for those looking for something ultra-lightweight for frequent transport. Noise level is an important consideration in generators, and while the DuroMax XP13000HX is quieter than many traditional generators, it’s still advisable to check local noise ordinances if using it in residential areas. Safety features, including a CO alert, provide additional peace of mind when operating the generator.

The generator's relatively heavy weight could pose a challenge for some users. Additionally, while the warranty is solid at five years, maintenance may require some effort, especially for those unfamiliar with generator upkeep. The DuroMax XP13000HX is a powerful and versatile generator ideal for homeowners needing reliable backup power. Although it's not the lightest option available, its features and dual-fuel capability make it a strong choice for those who prioritize performance and fuel flexibility.
