10 Best Cordless Weed Eaters 2025 in the United States

The EGO POWER+ 15" cordless string trimmer is a strong contender for anyone needing a reliable and easy-to-use cordless weed eater. It comes with a powerful 56V, 2.5Ah lithium battery that provides good run time and charges quickly in about 50 minutes. The 15-inch cutting width is wide enough to cover most lawn trimming jobs efficiently without feeling bulky. Weighing 7.4 pounds, it strikes a reasonable balance between being lightweight for easy handling and sturdy enough for tougher weed cutting. The split shaft design is practical as it allows for easier storage and versatility, like edging. One standout feature is the Rapid-Reload head, which makes changing the cutting line fast and hassle-free, saving time compared to older designs. The brushless motor means less vibration and longer life, plus the trimmer is weather resistant, so it can handle light rain without issue. Variable speed control adds flexibility for different trimming needs.

A potential downside is that the battery capacity of 2.5Ah may limit continuous use for large yards, meaning you might need extra batteries for longer jobs. Also, while the tool is well-built, the weight might be noticeable during extended use for some users. This trimmer delivers solid power and convenient features, making it ideal for homeowners looking for a cordless tool that’s easy to maintain and effective for regular lawn and weed trimming tasks.

The EGO POWER+ 16" string trimmer stands out as a powerful and user-friendly cordless weed eater, especially suited for homeowners who want a balance of performance and convenience. It uses a strong 56V battery with a 4.0Ah capacity, offering up to 60 minutes of runtime, which is enough for most medium to large yard jobs on a single charge. The 16-inch cutting width is wide enough to cover ground efficiently without making the tool too bulky or hard to maneuver. Weighing 7.5 pounds, it’s relatively lightweight for a battery-powered trimmer, which helps reduce arm fatigue during longer use. A key highlight is its patented Line IQ technology that automatically feeds the string without bumping, and the PowerLoad system that simplifies reloading the line with just a push of a button—both great time-savers and very convenient.

The telescoping carbon fiber shaft is another plus, allowing easy height adjustments for comfort and better ergonomics; plus, carbon fiber adds strength while keeping the tool light. While 7.5 pounds is light compared to gas models, some users might still find it a bit heavy if they have limited strength or need to trim for extended periods. Also, the price tends to be on the higher side compared to some basic cordless trimmers, reflecting its premium features.

The IPX4 rating means it's somewhat weather resistant but not fully waterproof, so caution is needed in wet conditions. This EGO model is well suited for those who want a reliable, efficient, and easy-to-use cordless trimmer with modern features, especially if quick line reloading and adjustable shaft length are important to them.

The Greenworks 40V 12" Cordless String Trimmer is a solid choice for light to medium yard work, especially for those who want the convenience of a battery-powered tool without dealing with gas and oil. Its 40V battery and 2.0Ah capacity provide enough power to cut through tough grass and weeds, while the included battery recharges quickly in about an hour. With a 12-inch cutting width, it’s well suited for trimming along edges and around plants but may take longer for larger areas compared to wider models. The automatic line feed system makes replacing the cutting line simple, reducing maintenance time.

Weighing 12 pounds, the trimmer is relatively lightweight, which helps reduce fatigue during extended use. The variable speed trigger offers better control around delicate areas. The straight shaft design provides good reach, though some users might prefer curved shafts for comfort. It features a push-button start and is maintenance-free, making it very user-friendly.

This trimmer is a quiet, eco-friendly option ideal for homeowners seeking easy trimming with decent power and portability. However, those with very large yards or thick brush might find it less powerful than higher voltage or gas models.
