10 Best Portable Generators Rating 2025 in the United States

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 XP13000HX is a powerful portable generator with a high output of 13,000 starting watts and 10,500 running watts, making it capable of powering a whole home during outages. Its dual fuel option allows you to run it on gasoline or propane, which is great for flexibility and fuel availability—propane burns cleaner and lasts longer in storage. The generator features a robust 500cc engine with all copper windings, designed for durability and long life. Starting it is easy with the electric push-button start and a digital display for convenience.

Portability is supported by included wheels and a handle, but at 245 pounds, it’s quite heavy, so it may not be ideal for frequent moving by one person. It offers a good range of outlets, including regular household plugs, a 30 amp, and a 50 amp transfer switch-ready outlet, making it versatile for different power needs. Safety is addressed with a carbon monoxide (CO) alert system, which is important when using a generator at home.

While the product is described as portable, it is fairly bulky and may be noisy during operation, which is common for generators of this size but worth considering if noise is a concern. This generator is well suited for residential users needing reliable, strong power backup with flexible fuel options and multiple outlets, though it requires some effort to move around and might be loud in quiet neighborhoods.

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.
