10 Best Cordless Weed Wackers 2025 in the United States

The EGO POWER+ String Trimmer is a solid choice for anyone seeking a cordless weed wacker that balances power and ease of use. It runs on a 56V battery, which provides strong performance and is compatible with all EGO ARC Lithium batteries, making it versatile if you already own their products. Its 4.0Ah battery offers a decent runtime, enough for typical yard work without frequent recharging. The 16-inch cutting width is a good size for trimming around lawns and gardens, allowing efficient clearing of weeds and grass in one pass.

Weighing 7.5 pounds, this trimmer is relatively lightweight, helping reduce arm fatigue during extended use. The telescopic carbon fiber shaft is a standout feature, as it adjusts to your height for comfortable handling, which is not always common in cordless models. It also features a professional-grade dual line with a spiral twist line feed system (Line IQ), which feeds line automatically as needed, saving you the hassle of manual adjustments.

The brushless motor enhances efficiency and durability, while the digital 2-speed selector lets you switch between power levels depending on the task, which helps conserve battery life. The weather-resistant construction means it can withstand light moisture, adding to its reliability. While the battery life is good, heavy-duty trimming on thick weeds may drain it faster, so having a spare battery might be beneficial. Assembly is required, which might need some patience if you’re not comfortable putting tools together. Also, at 7.5 pounds, it’s not the lightest in its class but remains manageable. This trimmer is best suited for homeowners who want a powerful, easy-to-use cordless tool with comfort features like the adjustable shaft and automatic line feed. It is especially appealing for those who value battery compatibility within the EGO ecosystem and want a durable, weather-resistant design.

The DEWALT 20V MAX* XR String Trimmer is a strong choice for those needing a reliable cordless weed wacker. Its 14-inch cutting width offers a good balance between coverage and maneuverability, making it suitable for medium-sized yards or trimming around obstacles. Weighing about 9 pounds, it is somewhat on the heavier side compared to some competitors, which might affect ease of use during extended periods.

The trimmer features a folding hinge that helps reduce storage space and makes transportation easier—great for users with limited storage. It uses a 20V battery, which is common and provides decent power, although the exact battery life depends on the battery pack you use (note that the battery is sold separately). The variable-speed trigger and Hi/Lo speed switch let you control the power for better performance or longer runtime, adding useful flexibility. The QuickLoad Spool system is a highlight—it simplifies and speeds up line replacement without fiddling, a definite plus for less experienced users.

This DEWALT model is well-suited for homeowners who want a sturdy, fairly wide cutting tool with convenient line loading and easy storage, though its weight and absence of an adjustable shaft for customizing handle height could be limitations for some.

The Greenworks 60V 16” Brushless Cordless String Trimmer is a strong choice for homeowners looking for a reliable and easy-to-use cordless weed wacker. Its 60V battery provides solid power, and the included 2.5Ah battery offers up to about 65 minutes of runtime, which is good for moderate yard work without frequent interruptions to recharge. The 16-inch cutting width strikes a nice balance—wide enough to clear grass and weeds efficiently but still manageable for detailed edging around sidewalks and flower beds.

This trimmer uses a brushless motor, which means it runs more efficiently and tends to last longer compared to standard motors. The dual-line bump feed system makes reloading the trimming line quick and hassle-free, so you won’t waste time dealing with jams or complicated adjustments. Weighing about 11.6 pounds, it’s lighter than many gas-powered models, which helps reduce user fatigue during longer sessions. However, it’s still a bit on the heavier side compared to some other cordless trimmers, so very small or limited mobility users might find it slightly less comfortable.

This Greenworks trimmer is well suited for homeowners who want a cordless, professional-grade tool that handles everyday trimming and edging efficiently with good power and manageable weight. It’s less ideal for those needing ultra-lightweight options or highly adjustable handles.
