10 Best Cordless Weed Trimmers 2025 in the United States

The BLACK+DECKER 20V MAX Cordless String Trimmer functions both as a trimmer and an edger, making it ideal for maintaining borders, sidewalks, and flower beds. One of its key strengths is its lightweight design, weighing just 5.7 pounds, which makes it easy to maneuver and handle, especially with the adjustable height handles. The cutting width of 12 inches is sufficient for most residential trimming tasks, and the automatic spool feed system ensures continuous work without the need to stop and bump the trimmer to feed more line.

The 20V lithium-ion battery provides decent power and runtime, featuring a runtime extension technology that allows for longer operation periods. Additionally, being part of the BLACK+DECKER 20V Max Power Connect System, the battery can be easily swapped between different tools from the same brand, enhancing versatility and convenience. However, the battery life, rated at 2 Ah, may not be sufficient for larger yards or prolonged use without recharging.

Although the tool is relatively low noise, it may still be loud compared to other quieter models on the market. This trimmer is well-suited for small to medium-sized yards and those looking for a lightweight, multifunctional tool with moderate power and convenience features.

The Worx String Trimmer Cordless GT3.0 20V PowerShare is a versatile 2-in-1 tool that functions both as a trimmer and an edger, making it a great option for maintaining your yard. It features a 12-inch cutting width, which is ample for most household needs. At just 6 pounds, it's relatively lightweight and easy to handle, even for extended periods of use. The trimmer is powered by two 20V lithium-ion batteries, which are included and can be used interchangeably with other Worx PowerShare tools. This flexibility can be very handy if you own other Worx products.

Additionally, the instant line feed system allows for quick and easy line adjustments, and the head tilts 90 degrees to help you reach difficult spots or work on sloped terrain. The rubberized wheels provide support and help you achieve cleaner cuts, while the adjustable spacer guard ensures you don't accidentally damage plants or decorations.

However, there are a few drawbacks to consider. The battery life may not be sufficient for larger yards, and you might need to recharge or swap out batteries mid-task. Assembly is required, which could be a downside for those looking for a ready-to-use tool straight out of the box. Despite these minor issues, the Worx GT3.0 20V trimmer is a solid choice for those needing a lightweight, adjustable, and versatile yard maintenance tool.

The EGO Power+ ST1623T is a solid choice for anyone looking for a cordless weed trimmer that combines power, comfort, and convenience. With its 56-volt lithium-ion battery, this trimmer promises a strong performance and a decent battery life, allowing you to tackle more extensive yard work without constantly recharging. The continuous 16-inch cutting width makes it efficient for trimming larger areas quickly, and the high-efficiency brushless motor ensures you get the job done effectively.

One of the standout features is the telescopic carbon fiber shaft, which can be easily adjusted to fit users of different heights, adding to its ergonomic design. This makes it a comfortable option for prolonged use. Additionally, the dual line spiral-twist design and the innovative LINE IQ™ line feed system provide an effortless trimming experience, ensuring that you maintain a neat appearance in your garden.

There are a few considerations to keep in mind. While the weight of 7.5 pounds is manageable for most users, it might still feel a bit heavy during extended use, especially for those who prefer lighter models. The assembly required might also be a slight drawback for some users who want a ready-to-go solution right out of the box. Lastly, the 5-year tool warranty and 3-year battery warranty are great perks, offering peace of mind regarding the product's reliability. If you prioritize a robust, adjustable, and user-friendly trimmer for regular yard maintenance, the EGO Power+ ST1623T could be a fantastic addition to your gardening tools.
