10 Best Cordless Weed Wackers 2025 in the United States

The DEWALT 20V MAX* XR String Trimmer is a strong choice for those needing a reliable cordless weed wacker. Its 14-inch cutting width offers a good balance between coverage and maneuverability, making it suitable for medium-sized yards or trimming around obstacles. Weighing about 9 pounds, it is somewhat on the heavier side compared to some competitors, which might affect ease of use during extended periods.

The trimmer features a folding hinge that helps reduce storage space and makes transportation easier—great for users with limited storage. It uses a 20V battery, which is common and provides decent power, although the exact battery life depends on the battery pack you use (note that the battery is sold separately). The variable-speed trigger and Hi/Lo speed switch let you control the power for better performance or longer runtime, adding useful flexibility. The QuickLoad Spool system is a highlight—it simplifies and speeds up line replacement without fiddling, a definite plus for less experienced users.

This DEWALT model is well-suited for homeowners who want a sturdy, fairly wide cutting tool with convenient line loading and easy storage, though its weight and absence of an adjustable shaft for customizing handle height could be limitations for some.

The EGO POWER+ String Trimmer is a solid choice for anyone seeking a cordless weed wacker that balances power and ease of use. It runs on a 56V battery, which provides strong performance and is compatible with all EGO ARC Lithium batteries, making it versatile if you already own their products. Its 4.0Ah battery offers a decent runtime, enough for typical yard work without frequent recharging. The 16-inch cutting width is a good size for trimming around lawns and gardens, allowing efficient clearing of weeds and grass in one pass.

Weighing 7.5 pounds, this trimmer is relatively lightweight, helping reduce arm fatigue during extended use. The telescopic carbon fiber shaft is a standout feature, as it adjusts to your height for comfortable handling, which is not always common in cordless models. It also features a professional-grade dual line with a spiral twist line feed system (Line IQ), which feeds line automatically as needed, saving you the hassle of manual adjustments.

The brushless motor enhances efficiency and durability, while the digital 2-speed selector lets you switch between power levels depending on the task, which helps conserve battery life. The weather-resistant construction means it can withstand light moisture, adding to its reliability. While the battery life is good, heavy-duty trimming on thick weeds may drain it faster, so having a spare battery might be beneficial. Assembly is required, which might need some patience if you’re not comfortable putting tools together. Also, at 7.5 pounds, it’s not the lightest in its class but remains manageable. This trimmer is best suited for homeowners who want a powerful, easy-to-use cordless tool with comfort features like the adjustable shaft and automatic line feed. It is especially appealing for those who value battery compatibility within the EGO ecosystem and want a durable, weather-resistant design.

The EGO POWER+ String Trimmer is a robust cordless weed wacker designed for efficiency and ease of use. Its 56V 2.5Ah battery provides substantial power, and the included rapid charger ensures minimal downtime with a 50-minute full charge time. The 15-inch cutting width allows for quick and effective trimming, while the dual feed spiral twist string ensures a clean cut on both weeds and grass. Weighing 7.4 pounds, it strikes a good balance between sturdiness and manageable weight, making it relatively easy to handle for prolonged periods. The adjustable shaft adds to its user-friendliness by accommodating different user heights and preferences.

Additionally, the variable speed control offers flexibility for different trimming tasks. A standout feature is the Rapid Reload head, which simplifies the process of loading new cutting line, enhancing convenience. The high-efficiency brushless motor is another plus, offering longer run times and less vibration, which contributes to user comfort and the tool's longevity. The weather-resistant (IPX4) design also provides peace of mind for outdoor use in various conditions.

On the downside, while the 2.5Ah battery included is decent for moderate tasks, heavy-duty users might find the battery life limiting and may need to invest in a higher capacity battery. The line feed system, while generally efficient, may occasionally require manual adjustment, which could interrupt the flow of work. The price point might also be a consideration for budget-conscious buyers. However, the 5-year tool warranty and 3-year battery warranty offer great value and assurance of the product’s durability. This trimmer is ideal for homeowners with medium to large yards who seek a reliable, high-performing tool.
