10 Best Battery Weed Wacker 2026 in the United States

The DEWALT 60V Cordless String Trimmer (model DCST972X1) is a solid choice if you're looking for a powerful battery-powered weed wacker that offers good balance between performance and convenience. Its 60V lithium-ion battery delivers strong power to handle regular trimming tasks, and the included charger means you’re ready to go right away. The cutting width adjusts between 15 and 17 inches, which provides some flexibility for different yard sizes—though it’s slightly smaller than some heavy-duty models.

At 15 pounds, it’s on the heavier side, so it might feel a bit tiring during long sessions, especially if you’re not used to carrying that weight. One of its standout features is the quick-load spool system, making it easy and fast to replace the trimming line without hassle. It also uses a dual-line system, improving cutting efficiency, and supports thicker DEWALT lines for tougher vegetation. The variable speed trigger and high/low speed control help optimize battery life and power depending on your trimming needs, which is handy for extending runtime.

Another plus is the attachment capability, which allows you to add other DEWALT tools to this base unit, adding versatility if you want more than just a trimmer. Assembly is required, but it’s generally straightforward for most users. While it’s a bit heavier and the 15-17 inch cutting swath might not suit very large areas, this trimmer suits homeowners who want a reliable, well-powered tool for typical lawn maintenance with some extra flexibility.

The DEWALT 20V MAX XR String Trimmer is a solid choice if you're looking for a reliable cordless weed whacker with a good balance of power and convenience. It runs on a 20-volt battery system, and DEWALT’s XR line is known for efficient power use. The 14-inch cutting width is wide enough to handle most yard trimming tasks without being too bulky, making it suitable for medium-sized lawns. Weighing just over 9 pounds, it is fairly lightweight, which helps reduce fatigue during use. The folding hinge allows the trimmer to be compact for storage or transport, which is a big plus if you have limited space.

You can adjust the speed with a variable trigger and a Hi/Lo switch, giving you control over performance versus battery runtime. The QuickLoad Spool system makes reloading the line fast and hassle-free, which is often a frustrating part of weed whacker maintenance. This model is sold as 'tool only,' so you’ll need to have or buy a compatible 20V MAX battery separately, which adds to the initial cost.

While it’s durable for thick brush, very heavy-duty or professional landscaping work might require a more powerful or larger machine. For homeowners wanting an easy-to-use, efficient trimmer for regular yard maintenance, this DEWALT model fits well.

The Worx GT Revolution 20V String Trimmer, also known as the WG170.2, serves multiple functions, effectively transforming into a string trimmer, edger, and mini-mower. This multi-tool capability makes it a versatile choice for various lawn care tasks. The trimmer's 20V battery offers the convenience of cordless operation, and it charges relatively quickly within an hour. However, the battery capacity is 2.0 Ah, which might not sustain long sessions for larger yards without needing a recharge. The cutting width of 12 inches is adequate for small to medium-sized gardens, allowing for precision without being too unwieldy.

Weighing only 5.5 pounds, the trimmer is lightweight and easy to maneuver, reducing user fatigue during extended use. With 7 handle adjustments and 6 rotating head settings, it provides a high level of adjustability to accommodate various user preferences and hard-to-reach areas. The automatic Command Feed line system is a notable feature that adds convenience, eliminating the need to stop and adjust the line manually. The twin rubberized wheels aid in maintaining stability during edging, resulting in cleaner and straighter lines. Additionally, the spacer guard helps protect plants and lawn decorations from accidental harm.

A potential drawback includes the assembly requirement, which might be a minor inconvenience for some users. Moreover, while the tool is part of the Worx Power Share family, enabling battery compatibility with other Worx tools, users are limited to the battery’s runtime, which may not be sufficient for extensive yards. This product is well-suited for users with smaller to medium-sized lawns looking for a versatile and easy-to-use solution for various trimming needs.
