10 Best Battery String Trimmers 2026 in the United States

The Worx 20V 12" Cordless String Trimmer & Leaf Blower combo is a practical choice for homeowners needing lightweight and versatile yard tools. It runs on a 20V battery system, which is standard for mid-range cordless trimmers, and includes two batteries plus a charger—great for continuous use without long waits. Having two batteries helps extend runtime. The 12-inch cutting swath is suitable for small to medium lawns, though it may feel a bit narrow for larger areas. A helpful feature is the push-button line feed system, which makes replacing or advancing the trimming line quick and hassle-free.

This model also converts easily between trimmer and edger modes, offering flexibility for different lawn edges and trimming needs. At about 5.3 pounds for the trimmer, it’s lightweight enough for most users to handle comfortably without fatigue. The included leaf blower is also impressively light and powerful, with a 360 cfm airflow at 75 mph, making it handy for clearing debris. The product requires some assembly, and while the combo is well suited for casual to moderate lawn care, serious or heavy-duty users might prefer a higher voltage or wider cutting swath.

This combo provides two useful cordless tools bundled together, delivering decent power and ease of use for regular yard maintenance.

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 EGO POWER+ String Trimmer is a strong option for those looking for a cordless tool to tackle weeds and grass with ease. It runs on a powerful 56V battery with a capacity of 2.5Ah, offering a good balance between runtime and weight. At just over 7 pounds, it is relatively lightweight, making it comfortable to use without quickly tiring your arms.

The 15-inch cutting swath is wide enough for efficient trimming but still manageable for detailed work around edges and tight spaces. A standout feature is the POWERLOAD head, which lets you load the trimmer line by simply pushing a button — this saves time and hassle compared to manually winding the line yourself. The dual-feed spiral twist line system provides consistent cutting performance, while the brushless motor and variable speed control offer power and flexibility for different trimming tasks.

Featuring a split carbon fiber shaft that can improve durability and handling, this string trimmer suits gardeners who want a reliable, easy-to-use cordless tool with good power and smart features. However, if you need the longest possible battery life or more customizable adjustments, you might want to check other models.
