10 Best Cordless Line Trimmer 2025 in the United States

The Greenworks 40V Cordless String Trimmer + Leaf Blower Combo Kit is designed to make yard maintenance easy and efficient. This combo kit includes a 12-inch string trimmer and a powerful leaf blower, both powered by a 40V battery. The 2.0Ah battery provides enough power for most residential tasks, and the push-button start makes it easy to use. The string trimmer features an auto feed head, which simplifies line advancement, and the 12-inch cutting width is sufficient for handling overgrown grass and weeds.

The leaf blower offers a strong 390 CFM air flow and a 110 MPH air speed, with a variable speed trigger and cruise control for better handling during use. Weighing only 16.5 pounds, this kit is lightweight and ergonomically designed to reduce user fatigue, making it a good choice for homeowners looking for a manageable and low-maintenance yard tool. The tools are also maintenance-free, with no gas, oil, or emissions to worry about, providing quiet operation.

However, the 2.0Ah battery might require frequent recharging for larger yards, and the 12-inch cutting width may not be sufficient for very large or heavily overgrown areas. Despite these drawbacks, the Greenworks 40V Combo Kit has received positive feedback from users, making it a reliable and effective solution for typical residential yard maintenance.

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 BLACK+DECKER 20V MAX Cordless String Trimmer and Edger is a versatile tool designed for those who need both trimming and edging capabilities in their yard maintenance. It boasts a battery voltage of 20V, which, along with its high-performance lithium-ion battery, provides extended runtime and is compatible with other BLACK+DECKER tools. This could be a significant advantage for users who already own compatible products. The trimmer's 12-inch cutting width is suitable for small to medium gardens, allowing efficient trimming of grass and weeds, although it may not be as effective for larger areas.

Weighing just 5.7 pounds, this tool is relatively lightweight, making it easier to handle and reducing fatigue during prolonged use. The adjustable shaft and soft-grip handle further enhance user comfort, allowing customization based on the user's height and preferred grip. However, the product's weight might still be a consideration for users with limited strength or endurance for extended sessions.

Notably, the automatic feed spool (AFS) system is a significant benefit, eliminating the need for manual line feeding and ensuring uninterrupted work. The 2-speed control feature allows users to choose between increased power for dense vegetation or longer battery life for lighter tasks, offering flexibility depending on the task at hand. The PowerDrive Transmission further enhances performance by delivering more torque for thicker grass and weeds.

A downside to note is that this model has been discontinued by the manufacturer, which might affect the availability of spare parts or service in the future. Nonetheless, for anyone needing a lightweight, dual-function tool, this BLACK+DECKER model ticks many boxes.
