10 Best Quiet Diesel Generators 2025 in the United States

The Westinghouse Outdoor Power Equipment 14500 Peak Watt Tri-Fuel Home Backup Portable Generator is a robust and versatile option for those needing a reliable backup power source for larger homes or a dependable portable power solution. One of its key strengths is its high power output, offering up to 14,500 peak watts and 11,500 running watts on gasoline, which is more than enough to power most home appliances during an outage. It also supports propane and natural gas, making it a flexible choice for various fuel availability scenarios.

The unit's 19-hour runtime on a 9.5-gallon fuel tank is impressive, ensuring long periods of operation without frequent refueling, which adds to its convenience and practicality during prolonged outages. However, at 230 pounds, this generator is quite heavy, which could make portability challenging despite its portable label. The durable construction and heavy-duty 550cc 4-Stroke OHV engine are designed for longevity, and the electric start feature adds ease of use.

Additional features like overload protection, automatic voltage regulation, and a CO sensor enhance safety and functionality. The generator is EPA compliant and comes with a 3-year limited service, labor, and parts coverage, providing peace of mind with the purchase. While it excels in power output, fuel efficiency, and durability, potential buyers should consider its weight.

The Westinghouse 11000 Peak Watt Dual Fuel Portable Inverter Generator is a solid choice for those needing a powerful and versatile generator. With a noise level kept low, it’s well-suited for quieter operation, which is a significant advantage for residential use or camping. It offers substantial power output with 9000 running watts on gasoline and 8100 running watts on propane, making it capable of handling a variety of electronic devices safely, thanks to less than 3% THD (Total Harmonic Distortion). This means your sensitive electronics will be protected from power surges.

The fuel efficiency is quite impressive, with up to 17 hours of run time on a 9.8-gallon tank, which is beneficial for long-term use without frequent refueling. The tank capacity of 9.8 gallons supports this efficiency. Portability is decent but could be better; at 187.4 pounds, it is on the heavier side, though it is equipped with wheels and a handle for easier movement. Durability is a strong point, featuring a heavy-duty 452cc engine with a cast iron sleeve and automatic low oil shutdown, plus a CO sensor to ensure safety.

The starting mechanism is user-friendly with a remote electric start, push button, and recoil options. In terms of drawbacks, the generator's weight might be a concern for some users, and although it is portable, it might require two people to move it comfortably. The price might also be higher compared to other models, but considering the features, it presents good value for money. Ideal users would be homeowners needing a reliable power backup, campers, and those with high power requirements for multiple electronics.

The Westinghouse 28000 Peak Watt Home Backup Portable Generator is a robust option for those needing significant power output. With 28,000 peak watts and 20,000 running watts, it can handle demanding loads, making it ideal for home backup during power outages. Its 999cc V-Twin OHV engine ensures durability, and the generator includes a range of safety features such as automatic low oil and carbon monoxide (CO) shutdown. The remote electric start with auto choke and push-button ease adds to its user-friendly design, ensuring quick and hassle-free operation.

Additionally, the generator offers a variety of outlets, including 120V and 240V options, making it versatile for different power needs. The 17-gallon fuel tank provides up to 11 hours of runtime at 50% load, which is quite efficient for its size and power output. However, at 599 pounds, this generator is not very portable. The reinforced steel handles and quick-release pins help, but it’s still a heavy and bulky unit.

Its noise level is not specified, but given its size and power, it may not be the quietest option available. This generator is best suited for those in need of a high-power, durable, and reliable backup power solution, but it may not be ideal for those looking for a portable or ultra-quiet generator.
