DuroMax XP15000HXT+ 15,000 Watt Portable Tri Fuel EFI Portable Generator - 50 State Approved
The DuroMax XP15000HXT+ is a robust portable generator delivering 15,000 watts at startup and 12,000 watts for continuous running. This level of power makes it capable of running an entire home, including large appliances and central air conditioning. One of its standout features is tri-fuel capability, meaning it can operate on gasoline, propane, or natural gas. This flexibility allows you to choose the most convenient or economical fuel option available. It also includes electronic fuel injection (EFI), which improves fuel efficiency and makes starting the engine—especially in cold weather—easier and more reliable.
The generator has an electric start system, removing the hassle of manual pull-starting. Multiple outlets on the power panel, including 120V household sockets and 30A and 50A connections, make it versatile for various power needs, including transfer switches for home backup setups. It weighs 245 pounds and comes with wheels and a handle kit, which helps with portability, though it’s still a heavy piece of equipment to move around. While it’s portable, it’s more suited for stationary use during emergencies or job sites rather than frequent transport.
The generator includes helpful safety features like a CO sensor and low oil shutdown to protect both the user and the engine. The 5-year warranty adds confidence in its durability. This generator is ideal if you need a reliable, powerful backup power source and appreciate the flexibility of running on three different fuels. If you’re looking for something lightweight or quieter for smaller tasks, this might be more than you need.
DuroMax XP15000HXT 15,000 Watt Tri Fuel Portable Home Power Backup HXT Generator w/CO Alert
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.

10 reviews
The GENMAX 13500W Tri-Fuel Inverter Generator offers strong flexibility by running on gasoline, propane, or natural gas, making it a solid choice if you want multiple fuel options during emergencies or outdoor activities. With a peak output of 13,500 watts and running wattage up to 11,500 watts on gasoline, it can handle heavy power demands like EV charging or multiple tools at once. Its 550cc engine is quiet for its size, operating around 62 dB, which is about the noise level of a normal conversation—ideal for home or camping without too much disturbance.
The 6.9-gallon fuel tank supports up to 11 hours of runtime, which is convenient for extended use without frequent refueling. Starting the generator is easy with five methods, including electric push-button, remote, Bluetooth app, and an automatic start system that activates during power outages, making it very user-friendly, especially for unattended operation. It also includes safety features like a carbon monoxide sensor that automatically shuts down the unit if CO levels get high, protecting your indoor air quality.
The generator has a sturdy frame with wheels and a foldable handle to help with portability, although at about 30 inches long and 29.5 inches high, it’s fairly large and best moved on wheels rather than carried. It is not smart home compatible, so it cannot integrate with home automation systems, which might be a limitation for some users. With many outlets and stable pure sine wave power safe for sensitive electronics, the price and size may be more than casual or light users need. This generator is an excellent fit if you want a powerful, versatile tri-fuel option with advanced start features and safety for home backup, RV, or demanding job sites, though it may be oversized or more complex than necessary for simple, occasional use.
