10 Best Generators 2025 in the United States

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.

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 Generac 7210 24kW Air Cooled Guardian Series Home Standby Generator is a robust choice for homeowners looking for dependable power during outages. One of its standout features is the impressive 24,000 watts of power output, which is more than sufficient to keep essential appliances running smoothly. The generator is designed to operate on natural gas or LP gas, making it flexible regarding fuel options. Its 200-amp transfer switch ensures that your entire home can be powered, providing peace of mind during unexpected blackouts.

Portability may not be a strong suit, as this generator weighs 455 pounds, making it more suitable for stationary installation rather than frequent relocation. On the positive side, the unit is engineered for easy installation by a licensed electrician, so you won't have to worry about the technicalities of setup.

A significant advantage is the Wi-Fi connectivity through Mobile Link, enabling remote monitoring. This allows you to check the generator's performance from anywhere and receive alerts about maintenance, which is especially useful for busy homeowners. While the generator is built to last and backed by a 5-year limited warranty, some users may find the initial investment to be significant. However, the quality of the G-Force engine and the advanced True Power Technology, which ensures clean energy with minimal distortion, justify the cost for many.
