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+ ST1502SA cordless string trimmer offers a robust 56-volt battery, providing substantial power for tackling weeds and grass. Its 15-inch cutting width is quite generous, allowing for efficient trimming in larger areas. Weighing in at 7.4 pounds, it strikes a good balance between being lightweight and durable, making it easier to handle without causing too much fatigue. The adjustable shaft feature ensures that users of different heights can comfortably use the trimmer. The Rapid Reload line feed system simplifies the process of reloading the cutting line, saving time and effort.

Moreover, the high-efficiency brushless motor promises longer run times, reduced vibrations, and extended motor life, contributing to a more pleasant user experience. A notable advantage is the weather resistance (IPX4), which adds durability for outdoor use in various conditions. The package includes a 2.5Ah battery and a standard charger, with a rapid 50-minute charge time from zero to full, which is quite efficient. Compatibility with all EGO batteries adds flexibility for those already using EGO tools.

On the downside, while the 2.5Ah battery is adequate, users with larger properties may find the battery life limited and might need to recharge or have a spare battery on hand. Additionally, although the tool is lightweight, handling it for extended periods may still cause some fatigue. In summary, the EGO Power+ ST1502SA is a strong contender for those looking for a powerful, efficient, and easy-to-use cordless weed trimmer, especially if they already own other EGO products.
