10 Best Battery String Trimmers 2025 in the United States

The Worx String Trimmer Cordless GT3.0 is a versatile tool that functions both as a string trimmer and an edger, making it handy for various lawn care tasks. It operates on a 20V battery system and comes with two batteries, ensuring you have extended runtime. The cutting swath is 12 inches, which is decent for small to medium-sized yards. At a weight of 5.3 pounds, it is relatively lightweight and easy to handle, especially with the rubberized wheels for support and guidance.

The head tilts 90 degrees, which is useful for trimming on slopes and hard-to-reach areas, and the adjustable spacer guard helps avoid damaging your plants and ornaments. The Command Feed spool system allows for instant line feeding, which is a convenient feature, and the free spools for life offer cost savings in the long run. However, the line diameter is 0.065 inches, which might not be suitable for very tough weeds. Additionally, while it provides a no-load speed of 7600 RPM, users with larger yards or heavy-duty requirements might find the battery needing frequent recharges.

Assembly is required, which might be a minor inconvenience for some users. This trimmer is ideally suited for homeowners with small to medium-sized lawns who value versatility and ease of use.

The Worx String Trimmer/Edger/Lawn Mower 3-in-1 GT Revolution is a versatile garden tool that combines a string trimmer, edger, and mini lawn mower. It operates on 20V batteries, which are included in the package, along with multiple accessories such as trimmer spools and a charger. While the 12-inch cutting swath might be slightly smaller than some other models, it is sufficient for typical residential use. The product's relatively light weight of 4.04 pounds makes it easy to handle, even for extended periods.

One of its standout features is the automatic fresh line system, which allows you to quickly add more line with the push of a button, reducing downtime during use. Additionally, the trimmer offers excellent adjustability with 7 handle adjustments and 6 rotating head settings, making it comfortable to use in various positions and reach difficult areas. The motor runs at 7600 RPM, providing strong performance for most garden tasks. However, the 5-hour charging time might be a drawback for users needing quick turnaround times.

This makes the Worx GT Revolution well-suited for homeowners looking for a multi-functional garden tool with flexible usage options and easy handling.

The Worx WG154 is a lightweight and versatile 2-in-1 battery string trimmer and edger that works well for homeowners needing a convenient tool for trimming and edging without buying two separate devices. It runs on a 20V lithium-ion battery with a 2.0 Ah capacity, which offers decent power for everyday yard work and can be swapped with many other Worx tools using the PowerShare system. The 10-inch cutting swath is good for small to medium lawn areas, providing efficient coverage without being too bulky. Weighing just about 4.2 pounds with the battery, it's easy to handle, reducing fatigue during use. The rotating head makes switching between trimming and edging simple and quick, which is great for detailed yard maintenance. The automatic line feed system means you won’t have to manually adjust the string often, saving time and effort. Plus, the adjustable flower guard helps protect plants and decorations, which is helpful for tidy work around sensitive spots.

The 2.0 Ah battery might run out faster on larger or tougher jobs compared to higher capacity batteries, and the 10-inch cutting width might be small for bigger yards, requiring more passes to finish. Also, assembly is required, so some upfront setup is necessary. This trimmer is ideal for users looking for a lightweight, easy-to-use tool for small to mid-sized yards who appreciate the convenience of a combined trimmer and edger with interchangeable batteries.
