10 Best Generators 2025 in the United States

The Westinghouse 28000 Peak Watt Tri-Fuel Generator is a powerful option designed mainly for larger homes needing reliable backup power. It provides a hefty 20,000 running watts on gasoline with a peak of 28,000 watts, which means it can handle heavy loads and multiple appliances at once. One big strength is its tri-fuel capability: it runs on gasoline, propane, or natural gas, offering flexibility if fuel availability varies. With a 17.2-gallon gas tank, it can run up to about 13 hours at a quarter load, which is good for extended outages.

Starting the generator is easy thanks to its remote electric start, and it has several outlets including heavy-duty 240V options ideal for whole-home connections via a transfer switch. The generator also includes features like automatic low-oil shutdown and idle control to protect the engine and save fuel. Portability is decent for its size, featuring large never-flat wheels and foldable handles, though at 557 pounds, it’s quite heavy and not something you’d move around casually.

This generator is well suited for homeowners looking for a robust and versatile backup power source capable of running large loads for hours. It may be more than needed for smaller homes or occasional use due to its size, weight, and complexity, but it offers excellent power output and fuel flexibility for those who prioritize backup reliability.

The DuroMax XP13000HXT is a powerful portable generator offering up to 13,000 starting watts and 10,500 running watts, making it suitable for whole-home backup during power outages or for commercial use. One of its standout features is the tri-fuel capability, meaning it can run on gasoline, propane, or natural gas. This flexibility lets you choose the most convenient or cost-effective fuel available. It has a robust 500cc engine designed to deliver reliable power and includes a push-button and remote start system for easy operation, which is handy if you need to start it from a distance.

In terms of run time, it provides about 8 hours of continuous use, which is decent for extended power needs but depends on the fuel type and load. Portability is supported by a wheel and handle kit, though at 240 pounds, it's quite heavy and might require some effort to move around. Noise level is around 74 decibels, which is moderate and typical for generators of this size—noticeable but not overly loud.

Connectivity options are plentiful with seven outlets, including a 50 amp transfer switch-ready outlet for easy integration with home wiring systems. It also features a digital display for monitoring performance, adding convenience. Safety is addressed with a CO Alert system to detect dangerous carbon monoxide levels. The size and weight could be challenging if you need something more easily portable, and while the 8-hour runtime is good, longer runtimes might require refueling during extended outages. The noise level is average and could be a consideration if you need a quieter solution. This generator suits users who require high power output, fuel flexibility, and convenient starting options in a fairly portable package.

The DuroMax XP15000HX is a powerful dual fuel generator delivering up to 15,000 starting watts and 12,000 running watts, making it well-suited for whole-home backup during outages or heavy-duty commercial use. Its ability to run on both gasoline and propane offers flexibility—propane is cleaner, lasts longer in storage, and is easy on maintenance. The generator features a large 670cc engine with all-copper windings, which means it’s built for durability and long-term use. Starting it is simple with a push-button remote electric start, and switching between fuels is quick thanks to a front-facing fuel selector. The control panel is user-friendly, showing important information like voltage and maintenance hours on a digital meter.

Safety is improved by a built-in carbon monoxide sensor that automatically shuts the unit down if harmful fumes are detected. It also comes ready to connect to a home transfer switch, so powering your house is straightforward. Portability is decent for its size, with included wheels and a handle, but at 345 pounds, it’s quite heavy and not something you'd want to move frequently by yourself. Large generators like this tend to be fairly loud, so some sound protection might be needed if used close to living spaces. It is not an inverter generator, so while it provides robust power, it may not offer the cleanest electricity for sensitive electronics.

If you need a strong, reliable generator for home backup or work sites and appreciate the dual fuel convenience plus safety features, the DuroMax XP15000HX is a solid choice to consider.
