10 Best Diesel Generators 2026 in the United States

The Westinghouse 28000 Peak Watt Home Backup Portable Generator is a robust option for anyone needing a reliable backup power source, particularly for residential use. With a peak output of 28,000 watts and running at 20,000 watts, it delivers significant power, making it suitable for larger appliances during an outage. The generator features an easy-start mechanism with a remote key fob and push-button electric start, which simplifies operation and adds convenience.

One of its standout strengths is the impressive run time of up to 11 hours at half load, thanks to the sizable 17-gallon fuel tank. This extended run time combined with its automatic low oil and carbon monoxide shutdown enhances safety and usability. Portability is manageable despite its 599-pound weight, as it includes reinforced steel handles, making it easier to move when necessary.

There are a few drawbacks to consider. While it offers multiple outlets for various connections, the generator can produce noise levels that may be disruptive, especially in quieter neighborhoods. Additionally, maintenance may be more involved due to its 999cc engine, which could be a concern for those unfamiliar with engine upkeep. Westinghouse backs this generator with a 3-year limited warranty and nationwide service, providing reassurance. Users looking for a powerful, versatile, and relatively easy-to-use generator for home backup will likely find the Westinghouse model meets their needs well. However, those sensitive to noise or with limited experience in maintaining large engines might want to explore simpler alternatives.

The DuroMax XP16000iHT is a powerful tri-fuel portable inverter generator delivering up to 16,000 watts of clean, stable power, suitable for whole-home backup, RVs, or job sites. It stands out with its ability to run on gasoline, propane, or natural gas, offering great fuel flexibility depending on your availability and preference. With dual 50-amp outlets, it easily supports full home power through a transfer switch, which is ideal for emergency backup situations. The remote electric start is a convenient feature, allowing you to start or stop the generator without going outside, especially useful during bad weather.

In terms of noise, this model uses inverter technology to keep sound levels relatively low, making it quieter than traditional generators and suitable for residential use and outdoor events. The included CO Alert safety feature adds peace of mind by automatically shutting off the unit if harmful carbon monoxide is detected. While it weighs 505 pounds, which makes portability a bit challenging, it is still considered portable for a generator of this size due to its design and wheels.

The 10.5-gallon fuel tank supports extended runtime, but exact fuel consumption rates depend on the fuel type used and load, which users should monitor via the smart digital control center. Its heavy-duty 744cc DuroMax engine is designed for durability and consistent performance. Maintenance is simplified with included tools and easy fuel switching, but the large size and weight mean periodic professional servicing may be needed. This generator suits those needing a reliable, high-power backup source with fuel flexibility and modern convenience features like remote start and digital monitoring. For those prioritizing maximum portability or extremely quiet operation, other lighter or quieter models may be preferable. The 5-year warranty also provides confidence for long-term use.

The Westinghouse Outdoor Power Equipment 14500 Peak Watt Tri-Fuel Home Backup Portable Generator is a versatile option for homeowners needing reliable backup power. With a peak output of 14,500 watts and a running output of 11,500 watts on gasoline, it provides ample power for larger homes or for outdoor activities. The flexibility to use gasoline, propane, or natural gas makes it a tri-fuel generator, allowing users to choose the most convenient or economical fuel option. Its impressive run time of up to 19 hours on a full tank makes it suitable for extended outages, which is a significant advantage for those in areas prone to power interruptions.

Portability is another strong point, though weighing in at 230 pounds, it might require some effort to transport. The built-in electric start feature is user-friendly, enhancing convenience, especially during emergencies. The generator also includes an automatic transfer switch (ATS) readiness, which allows for seamless power transfer, making it easier to use during outages.

On the downside, the noise level during operation might be a concern for some users, particularly in quiet neighborhoods. While it’s fairly quiet for a generator, it's still advisable to check local noise ordinances if you plan to use it frequently. Maintenance is manageable, given the durable 550cc engine; however, like all generators, it will require regular upkeep to ensure longevity.
