10 Best Generators 2025 in the United States

The Generac Guardian 26kW Home Standby Generator is a strong choice for homeowners who want reliable backup power during storms or outages. It delivers a solid 26,000 watts, which is enough to power an entire house, including essential appliances and systems. The generator works with natural gas or liquid propane, giving you fuel flexibility. Its 200 Amp transfer switch ensures smooth and automatic power transfer, so you don’t have to worry about manual setup when the power goes out.

One standout feature is its Wi-Fi connectivity, allowing you to monitor the generator’s status and maintenance needs remotely, which adds convenience and peace of mind. The unit is designed to be quiet for its size, with a fully enclosed casing and low oil shutdown to protect the engine. Built with a durable aluminum frame and crafted in the USA, it promises long-lasting performance backed by a 5-year warranty.

This generator is quite heavy at over 500 pounds and not portable, meaning it’s meant to be permanently installed by a professional electrician. This limits flexibility if you need something for occasional or mobile use. With 10 power outlets and stable voltage output, it’s well-equipped to handle multiple devices safely. If you want a dependable, automatic whole-house generator that you can keep an eye on remotely and don’t need portability, this model fits the bill well. It is better suited for those looking for a fixed installation rather than a generator to move around.

The Westinghouse 13500 Peak Watt Dual Fuel Portable Generator is a strong option for home backup power thanks to its high power output and flexible fuel choices. It delivers up to 13,500 watts at peak on gasoline and 12,500 watts on propane, which means it can handle most household appliances and tools during an outage. Its dual fuel capability—running on gasoline or propane—adds convenience and fuel availability, which is handy if one fuel type runs out. You can expect up to 19 hours of continuous run time on gasoline thanks to its large 9.5-gallon tank, helping keep your home powered for long stretches. Starting the generator is easy with both remote electric start and a recoil backup, so you don’t need to worry about manual pull-starting if conditions are tough.

It features important safety elements such as automatic low oil shutdown and carbon monoxide detection, giving peace of mind during use. The generator is built with heavy-duty components and includes multiple outlets for standard household plugs, RV connections, and transfer switch readiness, making it versatile for different power needs. On the downside, this model weighs 230 pounds, so while it’s portable with effort, it’s not something you’d want to move frequently without help. It also lacks inverter technology, which means the power output is less stable and might not be ideal for sensitive electronics like laptops or medical devices.

Noise levels aren’t specified but generators of this size typically produce noticeable sound, so consider placement if noise is a concern. This Westinghouse generator is well-suited for homeowners needing reliable, high-capacity backup power with the flexibility of dual fuel use, though it may be less convenient for those prioritizing lightweight or ultra-quiet operation.
