10 Best Portable Generators Rating 2025 in the United States

The DuroMax XP13000EH Dual Fuel Portable Generator is a robust option for anyone in need of reliable power during outages, whether at home, on an RV adventure, or at a job site. With a substantial power output of 13,000 watts, this generator can easily support household essentials and more, making it well-suited for emergency situations. One of its standout features is the dual fuel capability, allowing users to switch between gasoline and propane effortlessly, providing flexibility and convenience.

Portability is another strong point, thanks to its no-flat tires and heavy-duty construction, which can withstand rugged use. The electric start feature enhances user-friendliness, as it simplifies the ignition process. Additionally, the diverse range of outlets, including a 50 amp outlet, ensures compatibility with various devices.

The generator weighs a hefty 234 pounds, which might make it cumbersome for some users to transport, despite the built-in wheels. Furthermore, while DuroMax has a reputation for durability, it's important to consider regular maintenance to ensure longevity, especially with the complex engine setup. The DuroMax XP13000EH is ideal for homeowners looking for a dependable backup power solution or for outdoor enthusiasts needing portable power. However, potential buyers should be prepared for its weight and possible noise levels.

The Generac 18,000-Watt Portable Generator is a strong choice if you need a powerful, gas-fueled backup for your home or outdoor activities. Its 18,000 running watts and 22,500 starting watts mean it can handle large appliances and tools easily. It runs on gasoline, with a large 14.2-gallon tank providing about 9 hours of use per fill, which is good for extended power needs. Safety is a highlight here, with COsense Technology protecting against dangerous carbon monoxide and a low-oil shutdown feature that helps prevent engine damage. The engine is electronically fuel-injected, which improves efficiency and reliability.

At 427 pounds, this generator is quite heavy, so while it’s called portable, it will require some effort or a transport method to move around. It includes only three power outlets, which might limit how many devices you can plug in simultaneously. The TruePower Technology ensures your sensitive electronics like phones and computers get clean, steady power.

This model is well suited for homeowners or recreational users who need reliable, high power during outages or remote work but may not be ideal if you want something lightweight or very quiet.

The DuroMax XP15000HX is a powerful portable generator that delivers up to 15,000 starting watts and 12,000 running watts, making it well-suited for whole-home backup during outages or for commercial use. It runs on both gasoline and propane, giving you flexibility in fuel choice—propane is cleaner and can be stored longer, which is handy for emergencies. The 670cc engine is robust and designed to last, with all-copper windings that help extend its life.

It includes a user-friendly digital display showing voltage, frequency, and maintenance reminders, plus remote electric start and a front-facing control panel for easy fuel switching. Safety is a strong point, with a built-in carbon monoxide sensor that automatically shuts the generator off if dangerous fumes are detected. The generator offers a wide range of outlets, including multiple household 120V outlets and heavy-duty 120/240V options, one of which is ready for a transfer switch to connect directly to your home’s electrical system.

Portability is somewhat limited due to its weight—345 pounds—and large size, but it does come with wheels and handles to help move it around when needed. While the noise level is not specified, generators of this size typically tend to be louder. This model is ideal if you need high power output and fuel flexibility for home backup or job sites, and you are prepared to handle a heavier unit that requires some effort to move.
