The EGO POWER+ String Trimmer is a robust cordless weed wacker designed for efficiency and ease of use. Its 56V 2.5Ah battery provides substantial power, and the included rapid charger ensures minimal downtime with a 50-minute full charge time. The 15-inch cutting width allows for quick and effective trimming, while the dual feed spiral twist string ensures a clean cut on both weeds and grass. Weighing 7.4 pounds, it strikes a good balance between sturdiness and manageable weight, making it relatively easy to handle for prolonged periods. The adjustable shaft adds to its user-friendliness by accommodating different user heights and preferences.

Additionally, the variable speed control offers flexibility for different trimming tasks. A standout feature is the Rapid Reload head, which simplifies the process of loading new cutting line, enhancing convenience. The high-efficiency brushless motor is another plus, offering longer run times and less vibration, which contributes to user comfort and the tool's longevity. The weather-resistant (IPX4) design also provides peace of mind for outdoor use in various conditions.

On the downside, while the 2.5Ah battery included is decent for moderate tasks, heavy-duty users might find the battery life limiting and may need to invest in a higher capacity battery. The line feed system, while generally efficient, may occasionally require manual adjustment, which could interrupt the flow of work. The price point might also be a consideration for budget-conscious buyers. However, the 5-year tool warranty and 3-year battery warranty offer great value and assurance of the product’s durability. This trimmer is ideal for homeowners with medium to large yards who seek a reliable, high-performing tool.

The Greenworks 60V 13" Cordless String Trimmer & Leaf Blower Combo Kit is a solid choice for homeowners who want a powerful and versatile tool for lawn care without the hassle of gas-powered machines. Its 60V battery offers strong performance, and the included 4.0 Ah battery provides decent runtime for typical yard tasks, though heavy use might require a backup battery. The 13-inch cutting width is a good balance for trimming around flower beds and fences without being too bulky. The dual line bump feed system makes reloading quick and easy, which is helpful if you often trim thick or tough grass.

Weighing 22.1 pounds, it’s on the heavier side for a cordless trimmer, which could be tiring for longer jobs, but the ergonomic design helps reduce fatigue.

This kit suits users with medium-sized yards looking for a combo tool to keep both grass and leaves under control. For very large properties or longer continuous runtimes, additional batteries or a more heavy-duty model may be recommended. For casual to moderate use, this combo provides good power, convenience, and ease of use.

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.

Buying Guide for the Best Cordless Weed Wackers

Choosing the right cordless weed wacker can make your yard work much easier and more efficient. When selecting a weed wacker, it's important to consider various specifications that will determine how well the tool meets your needs. Understanding these key specs will help you make an informed decision and ensure you get the best fit for your gardening tasks.
Battery VoltageBattery voltage indicates the power output of the weed wacker. Higher voltage means more power, which is useful for tackling thicker and tougher weeds. Typically, battery voltages range from 18V to 80V. For light to moderate yard work, a 20V to 40V battery should suffice. For larger areas with dense vegetation, consider a 40V to 80V battery. Choose based on the size of your yard and the type of weeds you need to manage.
Battery LifeBattery life determines how long the weed wacker can operate on a single charge. This is crucial for uninterrupted work, especially in larger yards. Battery life is often measured in ampere-hours (Ah), with higher Ah values indicating longer run times. For small to medium yards, a battery with 2.0Ah to 4.0Ah should be adequate. For extensive areas, look for batteries with 5.0Ah or more. Consider how long you typically spend on yard work to choose the right battery life.
Cutting WidthCutting width refers to the diameter of the area the weed wacker can cut in a single pass. A wider cutting width means you can cover more ground quickly, which is ideal for larger yards. Cutting widths usually range from 10 to 15 inches. For small gardens or precise trimming, a 10 to 12-inch cutting width is suitable. For larger areas, a 13 to 15-inch cutting width will help you finish the job faster. Match the cutting width to the size of your yard and the precision required.
WeightThe weight of the weed wacker affects how easy it is to handle and maneuver. Lighter models are easier to use for extended periods and are less tiring. Weed wackers typically weigh between 5 to 15 pounds. For smaller yards or if you have limited strength, a lighter model (5 to 8 pounds) is preferable. For larger areas or if you need more power, you might opt for a heavier model (9 to 15 pounds). Consider your physical capability and the duration of use when choosing the weight.
Adjustable ShaftAn adjustable shaft allows you to change the length of the weed wacker to suit your height and reach. This feature is important for comfort and reducing strain on your back and arms. Some models offer telescoping shafts that can be easily adjusted. If multiple people of different heights will be using the tool, or if you need to reach under bushes or in tight spaces, an adjustable shaft is highly beneficial. Choose a model with this feature for greater versatility and comfort.
Line Feed SystemThe line feed system determines how the cutting line is advanced during use. There are three main types: bump feed, automatic feed, and fixed line. Bump feed requires you to tap the head on the ground to release more line, which gives you control but can be cumbersome. Automatic feed releases line as needed, offering convenience but potentially wasting line. Fixed line systems use pre-cut lengths of line, which are easy to replace but less flexible. Choose based on your preference for control and convenience.
