10 Best Natural Gas Home Generators 2025 in the United States

The Westinghouse 28000 Peak Watt Tri-Fuel Generator is a strong choice for homeowners needing a powerful backup power source, especially for larger homes. It offers impressive wattage, with up to 28,000 peak watts on gasoline and solid power even on natural gas (16,000 running watts), which is ideal for running multiple appliances during outages. Its tri-fuel capability (gasoline, propane, and natural gas) adds great flexibility depending on fuel availability, and the 17.2-gallon tank allows around 13 hours of runtime at a quarter load on gasoline, which is convenient for extended power needs.

The generator has a remote electric start and comes ready for an automatic transfer switch, making it easier to use during emergencies. It also protects sensitive electronics with clean power output, so you can safely run phones, computers, and TVs. While quite heavy at 557 pounds, it includes large, never-flat wheels and foldable handles that help with moving it around. The unit's maintenance is simplified by features like automatic low-oil shutdown and a digital display showing hours and voltage. Its size and weight mean it’s less portable than smaller models, which may be a consideration for some users.

This generator is well-suited for those who want reliable, high-capacity home backup power and are willing to accept its bulk in exchange for the power it delivers.

The electric start makes it user-friendly, avoiding the hassle of manual pull-starts. With a 7.5-gallon tank, it runs about 9 hours at half load on gasoline, which is decent for extended power needs.
