10 Best Cordless Line Trimmer 2025 in the United States

The Greenworks 40V 12" Cordless String Trimmer is a solid choice for homeowners needing a reliable tool for light to moderate yard trimming tasks. Its 40V battery provides enough power to handle tough grass and weeds, while the included 2.0Ah battery offers about an hour of use per charge, which is suitable for smaller lawns. The 12-inch cutting width is fairly standard, making it easy to maneuver around flower beds and shrubs, although it may take longer to cover larger areas compared to wider models.

Weighing 12 pounds, this trimmer is on the lighter side, helping reduce arm fatigue during extended use. It features an auto-feed line system that eliminates the need for manual adjustments, and the variable speed trigger allows good control over cutting power depending on the job. The battery charges quickly in about 60 minutes, and while the 2.0Ah capacity is adequate for typical tasks, longer or more demanding jobs might benefit from an additional battery. Its maintenance-free design with no gas or oil makes it easy to use and environmentally friendly.

This trimmer is well-suited for those seeking a lightweight, easy-to-use, and quiet cordless option for regular yard upkeep rather than intensive, professional-level trimming.

The EGO POWER+ String Trimmer (ST1623T) is a well-rounded choice for those looking for a battery-powered trimmer for their lawn care needs. It comes equipped with a robust 56V 4.0Ah battery and charger, ensuring ample power and runtime for most trimming tasks. The 16-inch cutting width makes it efficient in covering larger areas quickly, which is a notable advantage for users with bigger lawns or extensive trimming work. Weighing 7.5 pounds, it strikes a decent balance between portability and sturdiness.

The telescopic carbon fiber shaft is a standout feature, allowing for easy height adjustments to suit user comfort, which enhances usability for people of various heights. Additionally, the high-efficiency brushless motor promises durability and less maintenance over time. The dual line spiral-twist and digital 2-speed selector provide flexibility in handling different types of vegetation with precision. Its weather-resistant construction adds to its reliability, making it a suitable choice for various outdoor conditions. On the downside, the trimmer does require assembly, which might be a minor inconvenience for some users.

The inclusion of the POWERLOAD and LINE IQ systems simplifies line feeding and ensures continuous operation without manual intervention. With its strong performance and user-friendly features, the EGO POWER+ String Trimmer is a compelling option for both casual and more demanding lawn care enthusiasts.

The DEWALT 20V MAX* XR String Trimmer (DCST922B) offers a range of features suited for users looking for a reliable and portable cordless line trimmer. With a 14-inch cutting width, it covers a wide area, making it efficient for medium to large yards. The folding hinge is a standout feature, allowing for easy storage and transportation, which is ideal if you have limited space or need to move the trimmer frequently.

Weighing 9.2 pounds, it is relatively lightweight, reducing fatigue during extended use. The QuickLoad Spool feature simplifies the task of winding new line, which can save time and effort. Additionally, the variable-speed trigger and Hi/Lo speed control switch give you the flexibility to balance power and runtime according to your needs.

It is important to note that this model is 'tool only,' meaning the battery and charger are not included. This could be a drawback if you don't already own compatible DEWALT batteries. Also, while the trimmer is durable and can handle thick brush, 20V might not be sufficient for extremely tough and dense vegetation compared to higher voltage models. The DEWALT 20V MAX XR String Trimmer is best suited for homeowners seeking a balance of portability, ease of use, and effective performance in typical yard maintenance tasks.
