10 Best Dual Fuel Portable Generator 2026 in the United States

The DuroMax XP15000HX is a powerful dual-fuel portable generator that delivers up to 15,000 watts of starting power and 12,000 watts running power, making it well-suited for whole-home backup, RV trips, or job sites needing reliable electricity. Its dual fuel capability allows you to run it on gasoline or propane, with propane offering cleaner, more efficient, and longer-lasting fuel storage. This flexibility can be very useful during emergencies or extended use.

It comes with a strong 670cc engine and durable all-copper windings designed for longevity. Starting the generator is simple thanks to the push-button electric start and remote control, which adds convenience especially in bad weather. The digital control panel provides useful info like voltage and runtime, helping you monitor performance easily.

For connectivity, it offers a variety of outlets, including multiple household 120V plugs and heavy-duty 120/240V outlets, plus a 50-amp transfer switch-ready outlet, allowing you to safely power many devices or connect directly to a home's electrical system. While weighing 345 pounds, it includes wheels and a handle kit to aid portability, though it may still be challenging to move by one person over rough terrain. An important safety feature is the built-in CO Alert system that automatically shuts the unit down if carbon monoxide is detected, which helps protect your family. This generator suits homeowners needing reliable, flexible whole-house backup power, as well as RV owners and jobsite users who require robust and versatile fuel options. It balances strong performance with useful safety and convenience features for serious power needs.

The Westinghouse 14500 Peak Watt Dual Fuel Portable Generator is a strong choice for homeowners needing a reliable backup power source, especially for larger houses. It offers a high power output—up to 14,500 peak watts on gasoline and 13,500 on propane—which means it can run many household appliances and tools simultaneously. Its dual-fuel capability (gasoline or propane) adds flexibility, useful if one fuel runs out or is unavailable. The 9.5-gallon gas tank supports a long runtime of up to 19 hours at a stretch, while a standard 20 lb. propane tank lasts around 7 hours, so it can keep your home powered for extended outages.

Starting the generator is easy with the electric remote start, sparing you from dealing with pull cords. It includes safety and convenience features like automatic voltage regulation to protect your devices, a CO sensor for safety, and overload protection. Two power outlets provide enough connections for most home setups. However, at 230 pounds, it’s quite heavy, so while it’s portable, moving it might require wheels or extra help.

The durable 550cc engine with a cast iron sleeve promises reliability and longevity. It’s transfer switch ready, making it easier to connect to your home’s electrical system. This generator is well suited for homeowners who want a dependable, high-power dual-fuel unit with easy electric start and long runtime. Its weight and the sound it produces might be considerations if you plan to move it frequently or need something very quiet.

The Westinghouse 12500 Watt Dual Fuel Portable Generator is a strong option for homeowners needing reliable backup power. It offers solid power output with up to 9500 running watts on gasoline and 8500 on propane, enough to support most home essentials during outages. The dual-fuel capability provides flexibility, letting you choose between gasoline and propane, which is great for fuel availability and storage. It has a convenient remote electric start with a key fob, making it easier to use than pull-start-only models, plus a recoil start as a backup. Runtime is decent, offering up to 12 hours on a full 6.6-gallon gas tank, meaning it can last through many hours of use without refueling.

The generator includes various outlets, such as standard household plugs, an RV outlet, and a transfer switch-ready outlet, covering a wide range of connectivity needs safely with protective covers. It’s fairly heavy at 210 pounds, so while it’s technically portable, moving it around may require some effort or wheels. The built-in digital display helps monitor voltage and hours used, which is useful for maintenance. Although it comes mostly ready to go with included tools and accessories, some minimal assembly is necessary.

If you want a dependable, flexible generator for home backup with modern features and good power, this Westinghouse model is a solid choice, bearing in mind its weight.
