10 Best Cordless String Trimmers 2025 in the United States

The EGO POWER+ String Trimmer is a strong contender for anyone needing a cordless tool for trimming grass and weeds. Featuring a 56V 2.5Ah battery, this trimmer provides a good balance of power and battery life. The included battery and charger make it convenient right out of the box, and it only takes 50 minutes to fully charge, which is quite efficient. The 15-inch cutting swath means you can cover a good amount of ground quickly, and the dual feed spiral twist line enhances cutting performance, handling tougher weeds with ease.

One of the standout features is the Rapid-Reload head, which simplifies the often tricky task of loading new cutting lines. Additionally, the variable speed control offers flexibility for different trimming tasks, whether you need a gentle touch or more power. Weighing just 7.4 pounds, it should be relatively easy to handle for most users. The high-efficiency brushless motor promises longer run times and lower vibrations, making it more comfortable to use over extended periods. It's also weather-resistant to a certain degree (IPX4), which is a nice bonus for those unexpected rain showers.

Another plus is the fan-cooled charging system that helps prevent overheating, extending the battery's life. The product’s warranties (5 years for the tool, 3 years for the battery) provide added peace of mind. This trimmer is well-suited for homeowners looking for a reliable, easy-to-use cordless option with solid performance.

The Worx GT3.0 20V PowerShare Cordless String Trimmer/Edger is a versatile tool that offers a lot of convenience for garden maintenance. One of its major strengths is the 2-in-1 functionality, allowing it to switch easily from a trimmer to an edger, making it suitable for various tasks. The Command Feed spool system is a unique feature that ensures instant line feeding, reducing the hassle of manually adjusting the line. Another advantage is the inclusion of two 20V batteries, which extend usage time and can be used with other Worx tools, adding to their practicality.

At 6 pounds, it's relatively lightweight, making it easier to handle for extended periods without causing fatigue. The 12-inch cutting diameter is practical for small to medium-sized lawns, and the adjustable shaft adds comfort by accommodating different user heights. Additionally, the rubberized wheels and a tilting head improve maneuverability and precision on slopes and uneven terrains.

However, it may not be the best option for larger lawns due to its 20V battery, which might require more frequent recharging. Some users might find the noise level higher than expected, and while the product is well-designed, assembly is required which might be a minor inconvenience for some. This string trimmer is a solid choice for homeowners with small to medium lawns looking for a lightweight, versatile tool that is easy to use and maintain.

The Greenworks 80V 16 inch Brushless String Trimmer is a strong choice if you want a cordless trimmer that can handle tough grass and weeds efficiently. Its 80V battery provides plenty of power, and the included 2.0Ah battery charges quickly in about 30 minutes, which is convenient if you need to work for longer periods. The 16-inch cutting swath is a good size, allowing you to cover a decent area without too many passes. A brushless motor means quieter operation and less maintenance, which is nice if you want something reliable and easy to start without gas or oil.

The variable speed trigger helps you adjust the cutting speed to protect plants and maneuver easily. On the downside, it weighs 16 pounds, which might feel a bit heavy if you plan to use it for extended times or have limited strength. The shaft is adjustable, which helps with comfort and reach, and the bump feed line system makes reloading line quick and straightforward. Noise levels are lower than gas models but still present since it’s a powerful tool.

This trimmer suits homeowners looking for a balance of power and ease without the fuss of gas engines, but if you need something ultra-lightweight, there are lighter options available. It delivers solid performance for typical yard trimming jobs with the benefit of cordless convenience.
