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.

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.

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.

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.
