10 Best Trifuel Generators 2025 in the United States

The DuroMax XP15000HXT Tri Fuel Generator is a powerhouse that can generate up to 15,000 watts, making it well-suited for keeping your entire home operational during power outages. One of its standout features is its versatility in fuel choice, allowing you to run it on gasoline, propane, or natural gas, which provides significant flexibility depending on availability and cost of fuel sources. The generator’s powerful 500cc OHV engine is designed to deliver reliable performance. It also features a push-button and remote start, which simplifies the operation process, and a user-friendly front-facing interface for quick fuel type changes.

A variety of outlets, including a transfer switch-ready 50 amp outlet, ensures compatibility with a range of devices and applications. The fully-loaded power panel and advanced computer interface with a large LED display make monitoring and managing the generator straightforward, providing real-time information on gas usage, load, voltage, frequency, and run time. Additionally, the CO Alert feature is a crucial safety measure that automatically shuts down the generator to prevent carbon monoxide poisoning.

The 100% copper windings enhance durability and longevity, making it a reliable choice for both residential and commercial use. However, the generator is quite heavy at 362 pounds, which may impact its portability despite the included wheel and handle kit. Additionally, while it offers robust power and comprehensive features, the noise level could be a consideration for users in noise-sensitive environments. This product is ideal for those who need a high-capacity, versatile power backup solution with a strong emphasis on safety and ease of use.

The Westinghouse iGen8200TFc is a powerful trifuel generator offering great flexibility by running on gasoline, propane, or natural gas, with peak wattage up to 8200W on gasoline, which covers most home backup and camping needs. It features inverter technology that helps reduce fuel use and noise, making it quieter than many traditional generators—around 60 dBA at a quarter load, which is a noticeable plus for noise-sensitive environments. Its 3.9-gallon gas tank provides up to 17 hours of run time at 25% load, giving you long-lasting power without frequent refueling.

The generator is designed with safety in mind, including a built-in carbon monoxide sensor and automatic low oil shutdown. Starting the unit is easy thanks to the remote electric start, and it has useful outlets including a 50A outlet for home backup applications and RV-ready plugs. It is robustly built with a 298cc 4-stroke engine and copper windings, adding durability and cleaner power output safe for sensitive electronics.

At 134.5 pounds, it’s fairly heavy, so while it has flat-free tires for easier movement, it’s not the lightest option for portability. Also, while quieter than many, 60 dBA can still be noticeable if very low noise levels are required. The price and complexity might be more than casual users need if trifuel options or high power are not necessary. This generator is well suited for homeowners needing reliable backup power with flexible fuel choices or for outdoor enthusiasts who want a quiet, efficient, and versatile generator.

The GENMAX Tri Fuel Generator offers impressive power output, providing up to 10500 starting watts and 8500 running watts on gasoline, which makes it suitable for heavy-duty applications. Its ability to operate on gasoline, propane, and natural gas offers great flexibility and helps mitigate fuel shortages. This is particularly useful for home backup power during emergencies. The generator is equipped with a remote start feature, simplifying the process of turning it on and off, which is quite convenient.

Portability could be considered a downside due to its hefty weight of 298 pounds, potentially requiring more than one person to move it. However, its wheel kit is likely designed to partially address this issue.

The inclusion of various safety features such as overload and thermal protection enhances its reliability, while the CO shutoff provides peace of mind when it comes to safety. Additionally, the generator's panel includes multiple outlets and a voltage transfer switch, making it versatile for different power needs.

With a runtime of 14 hours, it offers long-lasting performance, which is ideal for prolonged power outages. Moreover, GENMAX provides a 1-year warranty and lifetime technical support, which adds value and support for users.

The GENMAX Tri Fuel Generator is an excellent choice for those needing a reliable, flexible, and powerful backup power solution. Its weight could be a drawback for some, but its fuel flexibility and robust power output make it an appealing option for home and emergency use.
