More Details on Our Top Picks
20V Cordless Weed Wacker String Trimmer 12″ 2-in-1 Edger for Yard
This cordless 20V model excels as a budget-friendly, versatile tool that combines trimming and edging in one device, thanks to its 180° foldable shaft and adjustable head. Compared with the EGO POWER+ trimmer, it offers a more affordable solution but sacrifices some runtime and power, making it less suited for large, dense areas. Its 9500 RPM motor provides sufficient speed for typical yard jobs, but the approximate 40-minute runtime and limited power for thick weeds are key tradeoffs. The dual batteries keep you working longer without frequent recharges, yet the runtime may require planning for bigger projects. It’s best suited for small to medium yards with routine maintenance needs.
Pros:- Versatile 2-in-1 design for trimming and edging
- Adjustable and foldable for compact storage
- Includes two batteries for extended use
Cons:- Limited runtime of around 40 minutes per charge
- Less powerful for thick or dense weeds
- Requires recharging between use sessions
Best for: Homeowners with small to medium yards looking for a flexible, budget-friendly tool
Not ideal for: Large properties or overgrown areas with dense, stubborn weeds—this may struggle with heavy-duty tasks
- Power Source:20V battery
- Cutting Width:12 inches
- Battery Capacity:2.0Ah (x2)
- Runtime:up to 40 minutes
- RPM:9500 RPM
- Adjustable Features:180° foldable shaft, 90° rotatable head
Our verdict“This trimmer is ideal for small yard chores and casual users prioritizing versatility and affordability.”
WORX 20V 12-Inch 2-in-1 Cordless String Trimmer & Edger, WG163
The WORX WG163 stands out for its quick transformation from trimmer to edger, making it perfect for homeowners who want fast, effortless yard work. Its lightweight design at just 5.5 lbs reduces fatigue, especially compared to heavier models like the Greenworks 40V combo, which offers more power but is bulkier. The instant line feed and adjustable, tilting head improve efficiency but may falter on larger or more stubborn weeds, requiring patience. The two 20V batteries provide decent runtime for small to medium tasks, yet for larger yards, battery life may become a limiting factor. This model suits users who prioritize maneuverability and easy switching over heavy-duty power.
Pros:- Convertible between trimmer and edger in seconds
- Lightweight for easy handling
- Compatible with all WORX 20V and 40V tools
Cons:- Battery life may be insufficient for larger jobs
- Requires two batteries for continuous operation
- Limited power for dense or thick weeds
Best for: Homeowners seeking a lightweight, quick-to-adjust tool for routine yard maintenance
Not ideal for: Large, overgrown properties or jobs demanding heavy-duty power, where longer runtime and more torque are necessary
- No-load speed:7600 rpm
- Cutting diameter:12 inches
- Weight:5.5 lbs
- Line length:10 inches
- Line diameter:0.065 inches
- Batteries included:2x20V Power Share lithium
Our verdict“This pick is best for small to medium yards where quick, light-duty trimming is needed with minimal fatigue.”
20V Cordless Electric Weed Wacker and Edger, 12-Inch Lightweight String Trimmer with 2 Batteries and Charger
This lightweight 20V trimmer is designed for quick, everyday yard work, with a 12-inch cutting width and an adjustable head that simplifies edging and trimming. Its 9500 rpm motor ensures decent speed, but the 30-minute runtime per battery limits its use to smaller projects, especially compared to the EGO model offering longer operation times. The foldable design makes storage straightforward, yet handling light-duty tasks is where it truly excels, particularly for users who prefer a manageable, straightforward tool. It’s less suitable for dense weeds or larger landscapes where longer runtime and more power are required.
Pros:- Lightweight and easy to maneuver
- Automatic line feed reduces manual bumping
- Includes two batteries for longer sessions
Cons:- Limited runtime per battery (30 minutes)
- Not suited for very dense or tough weeds
- Requires proper handling to avoid line breakage
Best for: Homeowners with small yards who want a lightweight, easy-to-handle trimmer for regular maintenance
Not ideal for: Larger properties or overgrown areas where extended runtime and higher power are needed
- Power Source:Battery Powered
- Cutting Width:12 inches
- Speed:9500 rpm
- Number of Batteries:2 Lithium Ion
- Battery Average Life:30 minutes
- Item Dimensions:40″L x 8″W
Our verdict“This model works best for small, routine yard tasks where ease of use is more important than power or runtime.”
Greenworks 40V 12 in String Trimmer & 390 CFM Blower Combo, 2.0 Ah Battery
The Greenworks 40V combo offers a balanced solution for those who want both trimming and blowing capabilities, with a focus on yard cleanup. Its 40V battery provides more power and longer runtime than 20V options, but at a heavier weight of 8 lbs, it’s less nimble than smaller models like the WORX. The blower’s 110 MPH air speed and 390 CFM airflow excel at debris removal, yet the trimmer’s auto-feed line can sometimes jam, and the 60-minute full charge time may slow down larger projects. This duo suits users who prioritize powerful, quiet operation and a comprehensive yard maintenance kit, despite some handling and runtime limitations.
Pros:- Lightweight and manageable at 8 lbs
- Powerful blower and trimmer for versatile yard work
- Compatible with other 40V tools in the ecosystem
Cons:- Battery life may be limited for extensive use
- Trimmer auto-line feed can jam occasionally
- Battery takes about an hour to fully charge
Best for: Homeowners needing a powerful combo for yard cleanup and edging, especially in smaller to medium yards
Not ideal for: Large properties or heavy-duty weed clearing where extended runtime and increased power are required
- Battery Voltage:40V
- Trimmer Length:12 inches
- Blower Air Speed:110 MPH
- Blower CFM:390 CFM
- Battery Capacity:2.0 Ah
- Weight:8 lbs
Our verdict“This combo delivers solid power for yard cleanup and edging but is best suited for small to medium spaces.”
EGO POWER+ 16″ Cordless Weed Trimmer with Battery and Charger
The EGO POWER+ 16″ trimmer elevates yard work with its 16-inch cutting width, making it a standout for larger areas compared to the 12-inch models. Its LINE IQ technology automates line feeding, reducing manual effort, while the brushless motor promises durability and consistent power. With up to 60 minutes of runtime, it surpasses most competitors, including the Greenworks and WORX options, especially for larger or more frequent trimming tasks. The telescopic shaft adds ergonomic comfort, though the 55-minute charge time and reliance on compatible batteries mean it’s less flexible for quick, small jobs. This model suits dedicated yard owners seeking high performance and long-lasting operation.
Pros:- Automatic line feeding with LINE IQ technology
- Longer runtime of up to 60 minutes
- Adjustable telescopic shaft for ergonomic comfort
Cons:- Requires compatible batteries for maximum runtime
- Charging takes around 55 minutes, which could delay quick jobs
- Higher price point compared to simpler models
Best for: Serious gardeners and homeowners needing extended runtime and advanced features for large or frequent yard work
Not ideal for: Casual users with small yards or those who prefer quick, lightweight tools for occasional trimming
- Battery:4.0Ah included
- Battery Compatibility:Works with all EGO 56V ARC Lithium batteries
- Cutting Width:16 inches
- Runtime:Up to 60 minutes
- Charging Time:55 minutes
- Motor:Brushless
Our verdict“This trimmer is tailored for users who prioritize extended runtime, durability, and feature-rich operation for extensive yard work.”
EGO POWER+ 15″ Cordless Weed Trimmer with Battery and Charger
This EGO POWER+ model stands out for its combination of power and battery flexibility. Its 15-inch cutting width and brushless motor deliver efficient trimming, comparable to the larger Greenworks 40V option but with more durability. The quick reload head and compatibility with all EGO 56V batteries streamline yard maintenance, though the included 2.5Ah battery may give shorter runtime compared to larger capacities like the Craftsman 4Ah pack. Its 45-minute runtime is sufficient for typical yard jobs, but heavier users might find it less enduring. The 50-minute fast charge is a major plus, especially over the 2-year warranty, making this a reliable, versatile choice for medium to large yards. However, its weight can be tiring for prolonged use, and requiring EGO batteries limits compatibility outside the brand.
Pros:- Powerful brushless motor for durability
- Long runtime with fast charging
- Compatibility with all EGO 56V batteries
- Quick and easy line reload system
Cons:- Battery life can vary depending on workload
- Heavy for extended use
- Requires EGO batteries, limiting flexibility
Best for: Homeowners with medium to large yards who want a reliable, high-performance trimmer with quick recharge capabilities
Not ideal for: Small yard owners or those seeking ultra-lightweight tools for quick, minor touch-ups
- Cutting Width:15 inches
- Line Diameter:0.095 inch
- Battery:2.5Ah included
- Runtime:Up to 45 minutes
- Charging Time:50 minutes
- Warranty:5-year tool, 3-year battery
Our verdict“This trimmer suits those who need serious power and battery flexibility for medium to large yards without sacrificing durability.”
BLACK+DECKER 20V MAX String Trimmer and Edger 2-in-1, Cordless Weed Wacker with Auto Spool Feed, Battery and Charger Included, 12-Inch Steel Deck, Reduced Vibration
This BLACK+DECKER 20V MAX model offers a lightweight, versatile solution for homeowners who want an easy-to-handle tool. Its 12-inch cutting width and automatic spool feed make it simpler to operate than some bulkier models like the Craftsman V20, especially for quick yard tasks. The dual functionality as a trimmer and edger provides convenience, but the smaller 20V battery results in limited runtime, especially compared to the 63-minute capacity of the Craftsman with a bigger battery. The steel deck adds durability but makes it slightly heavier than plastic alternatives. Its adjustable handle improves comfort, yet its lightweight design can sometimes feel less stable during prolonged use, particularly on uneven terrain.
Pros:- Convertible 2-in-1 trimmer and edger
- Automatic spool feed reduces bumping
- Lightweight with adjustable handle
- Includes battery and charger for convenience
Cons:- Limited runtime for larger jobs
- Steel deck adds weight compared to plastic models
- Battery capacity may be insufficient for heavy-duty tasks
Best for: Homeowners needing an affordable, easy-to-use tool for small to medium yards, especially those who value versatility
Not ideal for: Large yard owners or those with extensive trimming needs who require longer runtime and more power
- Power:20V MAX
- RPM:6200
- Cutting Width:12 inches
- Battery:2.0 Ah lithium-ion
- Warranty:2 years
- Features:Auto spool feed, adjustable handle
Our verdict“This model is perfect for budget-conscious homeowners seeking a lightweight, versatile trimmer for small to medium yards.”
CRAFTSMAN V20 String Trimmer and Lawn Edger Kit with 4Ah Battery and Charger
The Craftsman V20 kit excels in runtime and adaptability, making it a strong choice for users with larger lawns. Its 13-inch cutting width and two-speed settings allow for tailored trimming, comparable to the EGO but with an advantage in longer operation—up to 63 minutes—thanks to the 4Ah battery. Its adjustable height and versatile design make it comfortable for prolonged use, especially compared to the Black+Decker’s limited runtime. The limited compatibility to V20 batteries means users invested in other systems might need to buy additional batteries, but for V20 system owners, this kit offers excellent value. The slightly narrower cut may be a downside for some users seeking wider coverage.
Pros:- Very long runtime of up to 63 minutes
- Adjustable handle and height for comfort
- Two-speed operation for different tasks
- Includes battery and charger for all-day use
Cons:- Limited to V20 batteries, reducing flexibility
- Might require two-speed adjustments for best performance
- Slightly narrower cutting width than some competitors
Best for: Large yard owners who prioritize long runtime and adjustable comfort in a cordless trimmer
Not ideal for: Users with small yards or those outside the V20 system who want broader cutting widths
- Battery:V20 4.0Ah
- Cutting Width:13 inches
- Runtime:Up to 63 minutes
- Line Diameter:0.065 inches
- Includes:String trimmer, spool, battery, charger
Our verdict“This trimmer is best suited for users with large yards who value extended runtime and ergonomic operation within the V20 system.”
20V 12-inch Cordless String Trimmer, Weed Wacker & Edger
This 20V model shines for users who need a light, maneuverable tool for smaller yards or quick touch-ups. Its 12-inch cutting width and 8000 RPM motor provide sufficient power for light trimming and edging tasks, especially considering its weight of just over 6 pounds. The inclusion of two 4.0Ah batteries and multiple spools offers extended use, surpassing single-battery models like the Black+Decker for larger jobs. Its automatic line feed reduces hassle, but the limited 12-inch width makes it less suitable for larger lawns. The requirement of 2 AAA batteries for operation is a minor inconvenience, and the lack of weather resistance info raises questions about durability in wet conditions.
Pros:- Lightweight and highly maneuverable
- Includes two batteries for extended operation
- Automatic line feed simplifies use
- Versatile for trimming and edging
Cons:- Limited to 12-inch cutting width
- Battery life may be shorter on demanding jobs
- Relies on AAA batteries for operation, which may be inconvenient
Best for: Homeowners with small to medium yards who want a lightweight, easy-to-handle trimmer for quick jobs
Not ideal for: Large yard owners or those with extensive trimming needs who require wider coverage and longer runtime
- Power Source:Battery Powered
- Cutting Width:12 inches
- Speed:8000 rpm
- Number of Batteries:2
- Batteries Required:2 AAA batteries
- Item Dimensions:17.32″L x 6.69″W
Our verdict“This lightweight trimmer is ideal for small yards and quick touch-ups, especially for users prioritizing ease of handling over wide coverage.”
How We Picked
I evaluated each battery string trimmer based on performance, such as cutting power and runtime, as well as usability factors like weight, balance, and noise levels. Build quality and durability played a key role, along with battery life and the availability of spare batteries. I also considered value for money, including included accessories like chargers and extra batteries. Products were ranked to reflect their suitability for different user needs, from casual homeowners to more demanding enthusiasts, ensuring each pick serves a specific purpose effectively.Factors to Consider When Choosing Battery String Trimmer
Choosing the right battery string trimmer involves more than just looking at specs. Understanding how power, weight, and features interact can help you avoid common pitfalls, such as buying a lightweight model that lacks sufficient runtime or a powerful one that’s too heavy for extended use. This guide highlights key factors to consider so you can make an informed decision tailored to your yard size and personal comfort preferences.Power and Voltage
The voltage rating of a trimmer directly impacts its cutting power and runtime. Higher voltage models, like 40V, tend to handle thicker weeds and larger areas more effectively, but often come with increased weight. Lower voltage options, such as 20V, are more lightweight and easier to maneuver, making them suitable for smaller yards or light maintenance tasks. Consider your yard size and the thickness of weeds you typically encounter when choosing power levels to avoid over- or under-investing.
Battery Life and Runtime
Battery capacity and efficiency determine how long you can work without recharging. Larger batteries provide longer runtimes but add weight, which can cause fatigue. Some models come with dual batteries or quick-charging features, extending operation time for bigger projects. Pay attention to the average runtime per charge relative to your yard size, and consider whether additional batteries are worth the extra cost for uninterrupted work.
Weight and Ergonomics
Weight is a critical factor—heavier trimmers can cause fatigue, especially during extended use. Ergonomic features like adjustable handles, vibration reduction, and balanced weight distribution improve comfort. For users with limited strength or mobility issues, lighter models provide better control, but may sacrifice some power or battery capacity. Always test or review weight specifications to ensure the trimmer suits your physical comfort.
Versatility and Features
Features like 2-in-1 design for edging, adjustable shafts, and automatic spool feeds enhance usability. These additions can save time and effort but often come at a higher price. Decide which extras are essential for your needs—if edging is a frequent task, a dedicated feature-rich model makes sense. Conversely, if you only need basic trimming, a simpler design might suffice and save money.
Brand Compatibility and Accessories
Consider whether the brand’s batteries are compatible with other tools you own, as this can reduce costs and storage clutter. Some brands offer extensive accessory options, like additional batteries or specialized blades, which can be worthwhile investments. Be aware that cross-brand compatibility is rare, so choosing a system that aligns with your existing tools can streamline maintenance and replacements.
Frequently Asked Questions
How long does a typical battery last on a string trimmer?
Battery life varies based on capacity, power level, and the thickness of weeds. Most 20V batteries offer between 20 to 40 minutes of runtime for standard yard work, while higher voltage batteries like 40V can extend this to over an hour. Keep in mind that dense weeds and heavier loads drain batteries faster, so larger batteries or extra spare ones are recommended for bigger projects. Choosing a model with quick-charging capability can also help maximize your trimming time in a single session.
Is a higher voltage trimmer always better?
Not necessarily. Higher voltage models deliver more power and longer runtimes, which is beneficial for tackling thick weeds or larger yards. However, they tend to be heavier and more expensive, making them less ideal for quick, light tasks or users sensitive to weight. Lower voltage models are lighter, easier to handle, and often more affordable, but may struggle with dense or tough vegetation. Match the voltage to your yard size and the types of weeds you typically encounter.
Can I use the same battery across different brands?
Generally, batteries are not cross-compatible across different brands due to proprietary designs and voltage standards. Some brands offer compatible battery systems, but most require you to stick with their ecosystem. If you already own tools from a specific brand, selecting a trimmer with that brand’s batteries can save money and simplify your setup. Always verify compatibility before purchasing additional batteries or tools to avoid frustration and extra costs.
How important are vibration reduction features?
Vibration reduction significantly enhances comfort, especially during long or frequent trimming sessions. Excessive vibration can lead to fatigue or discomfort, reducing your overall control and efficiency. Many modern models incorporate anti-vibration systems to minimize strain on your hands and arms. If you anticipate extended use or have joint issues, prioritizing a trimmer with good vibration mitigation can make yard work more manageable.
Should I prioritize battery capacity or weight?
Balancing battery capacity and weight depends on your yard size and physical comfort. Larger batteries increase runtime but also add weight, which can cause fatigue over time. For smaller yards or lighter tasks, a lower-capacity, lighter battery may be more comfortable and still sufficient. For bigger yards, investing in a higher-capacity battery might be worth the extra weight, especially if it means fewer recharges or additional batteries needed during a session.
Conclusion
For general homeowners with small to medium yards, the EGO POWER+ 16″ Cordless Weed Trimmer offers a reliable mix of power and comfort, making it the best overall choice. Those prioritizing value should consider the BLACK+DECKER 20V MAX String Trimmer, which balances affordability with decent performance. For larger yards or more demanding tasks, the Greenworks 40V 12-inch String Trimmer provides extended runtime and power. Beginners or infrequent users will benefit from lighter, simpler models, while seasoned gardeners seeking maximum performance should look at premium options like EGO or CRAFTSMAN for their extra features and durability.
