10 Best Battery Powered Weed Eater 2025 in the United States

The EGO Power+ ST1502SA is a strong contender in the battery-powered weed eater category, ideal for homeowners and landscaping enthusiasts looking for a reliable tool to tackle weeds and grass. Its 15-inch cutting swath, powered by a high-efficiency brushless motor, makes it effective for larger areas while minimizing vibrations during use, which can enhance user comfort. The inclusion of a Rapid-Reload head is a significant plus, allowing for quick string changes without hassle, saving you time when you're in the middle of a job.

With a weight of just 7.4 pounds, this trimmer is quite lightweight, making it easy to maneuver around your yard. Additionally, its adjustable features and variable speed control cater to different working conditions, allowing users to customize their experience according to the task at hand.

One of the standout features is the 50-minute charging time for the 2.5Ah battery, which offers convenience, especially if you have multiple tasks lined up. Furthermore, the compatibility with all EGO batteries and tools is a significant advantage for those already invested in the EGO ecosystem.

The DEWALT 20V MAX* XR String Trimmer (DCST922B) is a solid choice for those looking for a reliable battery-powered weed eater. One of its main strengths is the 20V battery, which delivers solid performance and runtime, making it suitable for medium-sized yards. The 14-inch cutting swath is another highlight, offering a wide area of cut which means fewer passes are needed to trim your lawn.

At 9.2 pounds, it's relatively lightweight, although some users may find it slightly heavier than other models in this category. The folding hinge design is convenient for those with limited storage space and the QuickLoad spool simplifies the often tedious process of reloading the trimmer line. Additionally, the variable-speed trigger and Hi/Lo speed control provide flexibility between maximizing performance or extending battery life.

It’s worth noting that this model is sold as 'tool only', meaning the battery and charger need to be purchased separately, which could increase the cost. The ergonomic design is well-regarded, though some users might wish for more adjustability. This trimmer is best suited for users seeking a powerful yet flexible tool that offers a balance of performance and convenience, with the caveat of needing to buy the battery and charger separately.

The Greenworks 60V 16" Brushless Cordless String Trimmer is a strong choice for those needing a reliable battery-powered weed eater for medium to large properties. Its 60-volt brushless motor delivers power comparable to a 26cc gas trimmer, making it effective against thick weeds and tough vines. The 16-inch cutting swath helps cover areas quickly, ideal for trimming long fence lines or overgrown patches. The 2.5Ah battery provides up to 65 minutes of runtime per charge, which is decent for average yard work, and it recharges relatively fast in about 45 minutes.

Weighing around 11.6 pounds, it may feel a bit heavy for extended use, but the rotating handle design helps reduce wrist strain, improving comfort and control. It operates at a quieter 68 decibels compared to gas-powered models, allowing early morning use without disturbing neighbors. The spin-to-load head simplifies line replacement, saving time and effort compared to older bump feed systems. Additionally, the product comes with a 4-year warranty and fits into Greenworks’ ecosystem of tools using the same battery, which is a plus if you plan to expand your garden tool collection.

The battery capacity is moderate, so very large jobs may require a backup battery or charging break. While lighter than gas alternatives, it might still be tiring for users seeking a very lightweight option. This trimmer is well suited for homeowners looking for a powerful, quiet, and easy-to-maintain cordless weed eater for regular lawn and garden upkeep.
