Best Cordless Grass Trimmers and Edgers

Taming unruly lawn edges and trimming around obstacles without being tethered by a cord offers a significant upgrade in yard work convenience. Cordless grass trimmers and edgers leverage battery power to provide freedom of movement, but the landscape of options can be daunting. This guide cuts through the noise to identify the most effective and user-friendly models for various needs, focusing on performance, battery life, and ergonomic design.

How this list was curated

Our evaluation of cordless grass trimmers and edgers was driven by a commitment to providing actionable insights. We focused on the following concrete criteria:

• Cutting Performance: We assessed the ability of each trimmer to tackle various types of grass and weeds, including thicker, more stubborn varieties, and how cleanly it edges.
• Battery Life and Charging: The runtime per charge and the speed of recharging are critical for completing yard work efficiently. We prioritized models offering substantial use before needing a recharge.
• Ergonomics and Weight: Ease of use over extended periods is paramount. We considered the balance, grip comfort, and overall weight of each unit.
• Durability and Build Quality: We looked for models constructed with robust materials that suggest longevity and resistance to the rigors of outdoor use.
• Versatility and Features: The ability to convert between trimming and edging, adjustable handle heights, and line replacement mechanisms were important considerations.

Top Cordless Grass Trimmers and Edgers for 2024

1. Greenworks 40V 14-Inch Cordless String Trimmer

Best for: Homeowners with medium-sized yards seeking a balance of power and portability.

Skip if: You have a very large property or need to clear dense, overgrown brush regularly.

This Greenworks model offers a compelling blend of adequate power for typical lawn maintenance and a manageable weight. Its 40V battery system is part of a wider ecosystem, allowing for battery interchangeability with other Greenworks tools. The 14-inch cutting path is sufficient for most residential applications, and the automatic line feed minimizes interruptions. The trade-off for this balanced performance is that it may struggle with exceptionally tough weeds or very thick, overgrown areas where higher voltage models would excel.

2. EGO Power+ 56V MAX 15-Inch String Trimmer with PowerLoad™

Best for: Users who value advanced features and a premium experience, with larger yards.

Skip if: Budget is a primary concern, or you prefer a simpler, no-frills operation.

EGO’s Power+ line is known for its robust performance, and this trimmer is no exception. The 56V battery delivers substantial power, capable of handling most trimming and edging tasks with ease. Its standout feature is the PowerLoad™ head, which automatically winds new line, a significant convenience. The 15-inch cutting width covers more ground per pass. However, this advanced functionality and higher voltage come at a higher price point, and the overall system can feel more substantial in hand.

3. Ryobi 18V ONE+ Cordless String Trimmer/Edger

Best for: Existing Ryobi 18V ONE+ tool owners or those on a tighter budget needing basic functionality.

Skip if: You require maximum power or extended runtimes for larger properties.

Leveraging the widespread Ryobi 18V ONE+ battery platform, this trimmer offers an economical entry point for those already invested in the system. It easily converts from trimmer to edger with a simple twist of the shaft. While its power is best suited for light to medium duty, it’s an excellent choice for maintaining smaller lawns and for users who prioritize tool consolidation. The primary limitation is its less aggressive cutting power compared to higher-voltage competitors, making it less ideal for heavy-duty tasks.

4. DeWalt 20V MAX XR Brushless String Trimmer

Best for: Landscaping professionals or serious DIYers needing a durable, high-performance tool.

Skip if: You are looking for a lightweight, entry-level option.

DeWalt’s reputation for professional-grade tools extends to its cordless string trimmers. This 20V MAX XR model features a brushless motor for enhanced power, efficiency, and durability. It’s designed for continuous use and offers excellent torque for tackling demanding jobs. The variable speed trigger provides control, and the robust construction ensures it can withstand professional use. The trade-off here is its higher cost and a weight that might be more than some homeowners need for occasional use.

5. WORX WG163 GT 20V Cordless Grass Trimmer Edger

Best for: Small yards and tight spaces where maneuverability is key.

Skip if: You need a wide cutting path or extensive battery life for larger areas.

The WORX WG163 stands out for its compact design and dual-functionality. It’s exceptionally lightweight and easy to handle, making it ideal for navigating intricate garden beds and tight corners. Its 20V battery provides adequate power for basic trimming and edging. The spool system is designed for easy line replacement. The limitation is its narrower 10-inch cutting width and a battery that may not last through larger yard tasks, making it best suited for smaller, more contained areas.

Surprising Pick: SKIL 40V Brushless String Trimmer

Best for: Users who appreciate innovative design and a focus on user comfort without sacrificing power.

Skip if: You are heavily invested in another brand’s battery ecosystem.

SKIL’s entry into the cordless outdoor power equipment market has been notable, and their 40V Brushless String Trimmer is a strong contender. It often flies under the radar compared to more established brands, but it offers impressive performance with its brushless motor, delivering ample power for most residential tasks. The design prioritizes ergonomics, featuring a comfortable auxiliary handle and balanced weight distribution. Its unique selling proposition lies in its intuitive operation and robust build, often at a more competitive price than comparable models from industry giants. The primary reason it’s a surprising pick is its ability to punch above its weight class in terms of power and user experience, often overlooked by consumers loyal to older brands.

Segmentation: Choosing the Right Cordless Grass Trimmer Edger Cordless for Your Needs

For the Casual Homeowner (Small to Medium Yards)

If your primary concern is maintaining a neat lawn and garden edges a few times a month, prioritize lightweight models with good battery life for their class and ease of use. Models like the Ryobi 18V ONE+ or WORX WG163 are excellent choices, especially if you already own batteries from these brands. They offer sufficient power for light to medium duty and are easy to handle.

For the Dedicated Gardener (Medium to Large Yards)

For those who take pride in their landscaping and have larger areas to maintain, power and runtime become critical. Look for models with higher voltage batteries (40V or 56V) and wider cutting paths. The Greenworks 40V and EGO Power+ 56V trimmers are strong contenders here, offering the performance needed for more demanding tasks and longer operating periods.

For the Property Owner with Tough Terrain (Large Yards, Overgrown Areas)

If your property features thick weeds, dense brush, or requires frequent, heavy-duty trimming, you need a robust machine. The DeWalt 20V MAX XR Brushless String Trimmer is built for this kind of work, offering professional-grade power and durability. While it might be overkill for a small, manicured lawn, it’s the workhorse you need for challenging conditions.

FAQ

Q1: How long do cordless grass trimmer batteries typically last?

A1: Battery life varies significantly by voltage, motor type (brushed vs. brushless), and the intensity of use. Lower voltage models (18-20V) might offer 20-40 minutes of runtime, while higher voltage (40-56V) models can provide 45-75 minutes or more on a single charge, depending on the specific battery amp-hour (Ah) rating.

Q2: Can I use a grass trimmer edger cordless for thick weeds and brush?

A2: For light to medium grass and weeds, most cordless models will suffice. However, for dense, overgrown areas or thick brush, you’ll need a higher-voltage model (40V or above) with a more powerful motor, often featuring brushless technology, and potentially a thicker gauge trimmer line.

Q3: What is the advantage of a brushless motor in a cordless trimmer edger?

A3: Brushless motors are more efficient, meaning they draw less power from the battery for the same amount of work. This translates to longer runtimes and more consistent power output. They also tend to be more durable and require less maintenance than brushed motors.
