10 Best Cordless Line Trimmer 2025 in the United States

The Worx String Trimmer Cordless 3.0 WG163.9 is a versatile tool that combines the functions of a trimmer and an edger. With a 20V battery (not included), it offers significant portability and convenience for small to medium-sized yards. The 12-inch cutting width is suitable for most home gardening needs, while its light weight of 4.63 pounds makes it easy to handle, even during extended use.

The adjustable telescopic shaft and handle ensure comfort and adaptability to different user heights and postures. Additionally, the 90-degree tilting shaft allows you to trim hard-to-reach areas with ease. One standout feature is the Command Feed spool system, which provides instant line feeding, minimizing interruptions during use. However, it’s important to note that this model is sold as a tool only, so you’ll need to have or purchase compatible WORX 20V batteries separately.

This trimmer is best suited for those who already own other WORX tools and batteries, or are willing to invest in the battery ecosystem. The WG163.9 is a practical and user-friendly option for home gardeners seeking flexibility and ease of use, though the additional battery purchase may be a consideration for some.

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 Greenworks 40V 13-Inch Cordless String Trimmer/Edger offers a versatile solution for garden maintenance with its 2-in-1 functionality, easily switching between trimming and edging with a button press. The 40V lithium-ion battery is a significant advantage, not only providing ample power with a 2.0Ah capacity but also being compatible with over 75 other Greenworks tools. This can be a cost-effective choice for users invested in the Greenworks ecosystem. Its 13-inch cutting width is ideal for homeowners with medium-sized lawns, striking a balance between maneuverability and efficiency.

The 90° pivoting head allows for trimming and edging at multiple angles, enhancing precision in garden maintenance tasks. The durable aluminum telescoping shaft adjusts to different user heights, promoting ergonomic comfort and reducing fatigue during extended use. At just under 11 pounds, it's relatively lightweight, which can be particularly beneficial for users who prefer easy handling. The automatic line feed system and push-button start offer convenience, making operation straightforward even for those less familiar with power tools. Being maintenance-free, it eliminates the hassle of dealing with gas, oil, and emissions, appealing to eco-conscious users.

However, its single .065-inch line might not be robust enough for tougher vegetation, which could be a limitation depending on the garden's needs. Additionally, while the product enjoys a solid reputation with a 4-star rating from over 9,500 reviews, some users might find the battery life limiting for larger areas, requiring frequent recharges. Despite these minor drawbacks, the Greenworks trimmer is a well-rounded tool that suits casual gardeners looking for a user-friendly and environmentally friendly option.
