Our Top 3 Picks For Best String Trimmers (June 2026)

Quick Comparison: Best String Trimmers In 2026

Budget Pick — BLACK+DECKER BESTA510 14-Inch 2-in-1 String Trimmer

What to Look for in a String Trimmer

When shopping for the best string trimmer for your property, several key features determine which model will serve you best. Understanding these factors will help you make an informed decision and ensure you get the right tool for your specific yard care requirements.

Power Source: Battery vs. Corded Electric vs. Gas

The power source is the first and most important decision when selecting a string trimmer. Battery-powered cordless string trimmers have surged in popularity, offering the convenience of unrestricted movement without the noise, emissions, or maintenance demands of gas-powered models. Modern lithium-ion battery technology in 20V, 40V, 56V, and 80V configurations provides impressive power and runtime that meets or exceeds the demands of most residential properties. Corded electric string trimmers like the BLACK+DECKER BESTA510 deliver consistent, unlimited power for smaller yards where dragging an extension cord is manageable. Gas-powered string trimmers remain the choice for commercial landscapers and properties with heavy, overgrown vegetation, though they require more maintenance and produce significant noise and exhaust.

Cutting Swath

The cutting swath, also referred to as the cutting path or cutting width, determines how much ground you can cover with each pass. A wider 14 to 16-inch cutting swath allows you to complete trimming tasks more quickly, making these models ideal for larger properties. Narrower 12-inch cutting paths provide better precision around delicate landscaping and are generally lighter and more maneuverable, making them better suited for small yards with tight spaces and intricate edging requirements.

Battery Life and Voltage

For cordless string trimmers, battery voltage and amp-hour (Ah) capacity directly impact performance and runtime. Higher voltage batteries such as the 56V EGO POWER+ models and the 80V Greenworks trimmer deliver more torque and cutting power for denser vegetation and larger areas. The amp-hour rating indicates how long the battery will last on a single charge. If you have a medium to large property, prioritize models with higher capacity batteries or those that come with multiple batteries to minimize downtime during your trimming sessions.

Feed System: Bump Feed vs. Automatic Feed vs. PowerLoad

The line feed mechanism affects how you interact with the trimmer during operation. Traditional bump feed systems require you to tap the cutting head on the ground to release more line, a familiar motion for experienced users. Automatic feed systems like BLACK+DECKER’s AFS continuously advance the line without manual intervention, eliminating interruptions during your work. Advanced systems such as EGO’s POWERLOAD technology offer push-button line winding that makes restringing quick and frustration-free. WORX’s Command Feed system provides on-demand line feeding at the push of a button, giving you full control over when additional line is deployed.

Motor Type and RPM

The motor type and speed measured in RPM (revolutions per minute) determines cutting efficiency. Brushless motors found in premium battery models like the EGO POWER+ ST1623T and Greenworks 80V deliver more power, run cooler, and last longer than their brushed counterparts. Higher RPM ratings generally mean cleaner cuts and faster completion of trimming tasks, though the relationship between motor speed and actual cutting performance is also influenced by the trimmer’s design, line type, and the density of vegetation being cut.

Line Size and Type

String trimmer line comes in various diameters typically ranging from 0.065 inches to 0.105 inches. Thicker, heavier-gauge line such as 0.095-inch professional-grade dual-line spiral-twist trimmer line found on EGO models handles tough weeds and thick grass more effectively than thinner lines. Round line works well for general use, while twisted or serrated line provides enhanced cutting performance for demanding conditions.

When budget is a primary concern, the BLACK+DECKER BESTA510 stands out as the clear winner among the best string trimmers available under $100. This corded electric weed wacker combines a powerful 6.5-amp motor with an impressive 14-inch cutting diameter to deliver reliable performance for small to medium yards at a price that won’t break the bank.

The BESTA510 features BLACK+DECKER’s Automatic Feed Spool technology, which eliminates the need for manual bumping to advance line during operation. This push-button advancement system keeps the trimmer running smoothly without interruption, allowing you to focus on achieving a clean, even cut along your lawn’s edges and borders. The POWERDRIVE Transmission ensures consistent power delivery to the cutting line, maintaining effective performance even when tackling thicker weeds and grass.

At just 6.3 pounds and featuring an adjustable auxiliary handle, this lightweight string trimmer is comfortable to use for extended periods without causing user fatigue. The 2-in-1 design includes wheeled edge guide functionality, converting quickly and easily between trimming and edging modes to handle both tasks with a single tool. The cord retention system prevents accidental disconnection from your extension cord during operation, eliminating frustrating interruptions mid-job.

The primary trade-off with the BESTA510 is its corded nature, which requires an extension cord for operation. This limits your range to the length of your cord and necessitates managing the cord while you work. However, for homeowners with small yards who value consistent power delivery without the hassle of battery charging or the expense of replacing batteries over time, the BESTA510 offers exceptional value. With over 17,000 customer reviews and a 4.4-star average rating, this proven model has satisfied countless homeowners seeking an affordable, dependable solution for their lawn trimming needs.

Best Overall Pick — WORX WG163 Cordless String Trimmer and Edger

The WORX WG163 earns our top recommendation as the best overall string trimmer for most homeowners, delivering an exceptional balance of performance, versatility, features, and affordability. With over 27,000 customer reviews and a 4.4-star rating, this 2-in-1 trimmer and edger has proven itself in real-world use across countless residential properties of varying sizes and conditions.

This cordless string trimmer operates on WORX’s innovative 20V PowerShare battery platform, which offers remarkable value through its cross-compatibility with the entire WORX garden tool ecosystem. The trimmer comes standard with two lithium-ion batteries and a charger, ensuring you always have a backup battery ready to swap in when one runs low. This dual-battery configuration effectively doubles your runtime, allowing you to complete larger trimming jobs without the frustration of stopping to recharge.

The WG163 features WORX’s Command Feed technology, a push-button instant line feeding system that puts you in complete control. Unlike automatic feed systems that may advance line at inopportune moments, Command Feed delivers line exactly when you want it, reducing line waste and ensuring optimal cutting performance throughout your session. The adjustable spacer guard protects your plants and lawn ornaments from damage while the 90-degree tilting head handles sloped terrain and those challenging hard-to-reach spots along fence lines and retaining walls.

As a 2-in-1 trimmer and edger, the WG163 transforms from a horizontal trimming machine to a vertical edging tool in just seconds using the included edger wheel. Rubberized wheels guide the edger along hardscape surfaces for straighter, cleaner lines that enhance your lawn’s overall appearance. The 12-inch cutting diameter and 7,600 RPM motor provide ample power for residential trimming needs, making quick work of grass, light weeds, and overgrowth along fence lines and landscape borders.

Best Battery Technology — EGO POWER+ ST1623T 16-Inch String Trimmer

For homeowners who demand the absolute best in battery-powered trimming technology and are willing to invest in a premium tool, the EGO POWER+ ST1623T represents the pinnacle of cordless string trimmer innovation. This feature-packed model combines LINE IQ automatic line feeding technology with POWERLOAD push-button line winding, delivering an unparalleled user experience that eliminates virtually every frustration traditionally associated with string trimmers.

The ST1623T’s LINE IQ technology represents a significant advancement in trimmer line management. This auto-sensing system continuously monitors the cutting line and automatically advances line as needed to maintain the optimal 16-inch cutting swath. The result is uninterrupted trimming without the constant attention to line length that other trimmers demand. When combined with the 0.095-inch professional-grade dual-line spiral-twist trimmer line, the ST1623T delivers clean, consistent cuts through grass, weeds, and light brush with remarkable efficiency.

The POWERLOAD technology solves one of the most common pain points in string trimmer ownership: restringing. With a simple push of a button, the ST1623T winds the trimmer line onto the spool automatically. This eliminates the frustration of tangled line, uneven winding, and the trial-and-error process that typically accompanies manual restringing. The telescopic carbon fiber shaft adjusts to your exact height with a lifetime warranty, ensuring a comfortable, customized fit that promotes proper ergonomics during extended use.

Running on EGO’s advanced 56V ARC Lithium battery platform, the ST1623T delivers up to 60 minutes of runtime with the included 4.0Ah battery. The high-efficiency brushless motor provides 5,800 RPM for effective cutting performance, while the digital two-speed selector allows you to optimize between maximum power for tough vegetation or extended runtime for routine maintenance trimming. The IPX4 weather-resistant construction ensures reliable operation in damp conditions, so you can continue your yard work even after morning dew or light rain.

Best Budget Battery Option — BLACK+DECKER LST522 20V MAX Cordless Trimmer

The BLACK+DECKER LST522 offers an compelling entry point into the world of cordless string trimmers without sacrificing the convenience of battery power. This 20V MAX model delivers the freedom of wireless operation at a price point that rivals many corded electric alternatives, making it an ideal choice for budget-conscious homeowners who want the flexibility of a cordless trimmer without a significant financial investment.

What sets the LST522 apart from other budget options is its Automatic Feed System (AFS), which ensures uninterrupted line advancement without manual bumping. This system automatically supplies the optimal amount of line as you trim, reducing line waste while maintaining consistent cutting performance throughout your session. The enhanced 2-speed PowerDrive transmission lets you choose between maximum power for dense vegetation or an energy-saving mode that extends battery runtime for lighter trimming tasks.

The included LBXR2520 battery provides an impressive 66% more runtime compared to standard BLACK+DECKER 20V MAX batteries, allowing you to complete more trimming on a single charge. Depending on your grass density and the selected speed setting, you can expect between 15 and 45 minutes of continuous operation, which is sufficient for most small to medium residential yards. The battery is part of the 20V MAX system, meaning it compatible with the entire range of BLACK+DECKER cordless tools, providing excellent value if you already own or plan to invest in other BLACK+DECKER power tools.

Weighing just 5.7 pounds with premium soft-grip handle, the LST522 is designed for comfortable extended use. The adjustable height and handle positioning accommodate users of different sizes, while the effortless conversion to wheeled edger mode enables clean, professional-looking edges along walkways, driveways, and landscape beds. The 12-inch cutting diameter provides a good balance between coverage and precision, making it easy to navigate around trees, garden beds, and other landscaping features.

Best Premium Battery Pick — EGO POWER+ ST1502SA 15-Inch Rapid Reload String Trimmer

The EGO POWER+ ST1502SA occupies the sweet spot between the entry-level LST522 and the flagship ST1623T, offering premium features and build quality at a mid-range price point. This 15-inch battery-powered string trimmer brings together EGO’s proven 56V battery technology with the Rapid-Reload head system and a high-efficiency brushless motor, creating a versatile tool well-suited for property owners who demand professional-grade performance without professional-grade equipment costs.

The Rapid-Reload head system on the ST1502SA represents a significant improvement over traditional bump feed mechanisms. When your trimmer line runs out, the Rapid-Reload head allows for quick, hassle-free line changes that take just seconds rather than the minutes typically required with conventional systems. This feature proves especially valuable during extended trimming sessions or when working in areas with abrasive surfaces that accelerate line wear. The high-efficiency brushless motor delivers consistent power throughout the battery discharge cycle, maintaining cutting performance from the first pull of the trigger to the last.

The split shaft design enhances the ST1502SA’s portability and storage convenience. By separating into two sections, the trimmer fits more easily in vehicle cargo areas and occupies less space in your garage or shed when not in use. This design also facilitates easier transport to different properties or job sites, making the ST1502SA an excellent choice for homeowners who maintain multiple yards or for semi-professional use where equipment transport is a consideration.

Variable speed control allows you to match the trimmer’s power output to the task at hand. Lower speeds extend battery runtime during routine maintenance trimming of established lawn edges, while higher speeds provide the extra power needed for tackling dense weed growth, thick grass, or light brush clearing. The included 2.5Ah battery charges from empty to full in just 50 minutes with the fan-cooled charging system, minimizing downtime between trimming sessions.

Best Versatile Option — WORX WG170 3-in-1 Trimmer/Edger/Mini Mower

If versatility ranks highest among your priorities when selecting the best string trimmer for your needs, the WORX WG170 stands alone as the most flexible option in our roundup. This remarkable 3-in-1 tool transforms seamlessly between a string trimmer, an in-line edger, and a mini lawn mower, effectively replacing three separate tools with a single compact device that costs less than $120 with two batteries included.

The WG170’s transformation between modes takes just seconds, requiring no tools for conversion. As a string trimmer, it handles the standard duties of maintaining clean edges along fence lines, around trees, and between landscaping elements. Switching to the edger mode positions the cutting head vertically with rubberized guide wheels that create crisp, clean edges along sidewalks, driveways, and pathway borders. The mini mower mode engages a rolling bar that trims grass to an even height in areas too tight for your lawn mower to navigate, such as narrow strips between flower beds or along retaining walls.

WORX’s Command Feed technology provides the same on-demand line advancement found on the WG163, putting you in complete control of when additional cutting line is deployed. The 7 handle adjustments and 6 rotating head settings ensure you can find the perfect configuration for your body size and the specific demands of each trimming zone in your yard. This adjustability proves especially valuable for households with multiple users of varying heights, as the WG170 can be quickly reconfigured to fit anyone from a teenager to a taller adult comfortably.

The 7600 RPM motor matches the power of the WG163, delivering effective cutting performance through grass and light weeds. The 12-inch cutting diameter provides good coverage for residential use while maintaining the precision needed for navigating around delicate plants and garden features. Like its sibling model, the WG170 operates on WORX’s 20V PowerShare platform and comes with two batteries and three spares, ensuring you have plenty of line and power capacity for any size yard.

Best High-Power Option — Greenworks 80V 16-Inch Brushless Cordless String Trimmer

For homeowners who refuse to compromise on cutting power and need performance that rivals gas-powered equipment, the Greenworks 80V 16-inch Brushless Cordless String Trimmer delivers where it matters most. This high-voltage battery-powered trimmer produces the raw power necessary to handle demanding yard work including thick overgrown vegetation, dense weed growth, and larger properties where lesser trimmers would struggle or require multiple battery swaps.

The 80V battery configuration places the Greenworks ST80L210 in a power class above the 56V EGO models and well beyond standard 20V and 40V consumer trimmers. This additional voltage translates directly to increased torque and cutting force, making quick work of weeds and grass that would bog down lesser trimmers. The high-efficiency brushless motor maintains consistent power delivery throughout the battery cycle while running quieter than gas-powered alternatives and producing zero direct emissions.

The 16-inch cutting path with 0.080-inch dual-line provides substantial coverage for faster job completion on larger properties. Variable speed control allows you to modulate power output based on the density of vegetation, conserving battery when tackling lighter growth while unleashing full power for demanding clearing tasks. The bump feed line advancement system offers familiar operation for users transitioning from gas trimmers, delivering line on demand with a simple tap of the cutting head against the ground.

Despite its impressive power output, the Greenworks 80V maintains relatively compact dimensions at 65 inches in length with a 7.5-inch width. However, prospective buyers should note that this model weighs 16 pounds, making it substantially heavier than most competitors in this roundup. This additional weight results from the larger, more powerful battery and motor assembly, and users should factor in the physical demands of maneuvering a heavier trimmer during extended cutting sessions.

Best Tool-Only Option — EGO POWER+ ST1510T 15-Inch PowerLoad String Trimmer

The EGO POWER+ ST1510T addresses a specific but significant market segment: homeowners who already own EGO 56V batteries and want a premium trimmer without paying for a duplicate battery and charger. This tool-only option delivers the same professional-grade features as the higher-priced ST1623T while eliminating the redundancy and expense of redundant power sources that would sit unused in your garage.

Like its sibling model, the ST1510T features EGO’s acclaimed POWERLOAD technology for push-button line winding that transforms the traditionally frustrating restringing process into a simple, foolproof operation. Simply insert the line, press the button, and the spool winds automatically in seconds. This technology alone makes the ST1510T worth considering even for users new to the EGO ecosystem, as it eliminates one of the most common sources of frustration in string trimmer ownership.

The telescopic aluminum shaft adjusts to your exact height preference, promoting proper ergonomics during extended trimming sessions. The 15-inch cutting swath with 0.095-inch dual-line spiral-twist trimmer line provides a balance of coverage and precision suitable for most residential applications. Bump-feed line advance gives you control over line deployment while the high-efficiency brushless motor ensures consistent power throughout the battery discharge cycle.

The ST1510T is compatible with the entire range of EGO 56V ARC Lithium batteries, from compact 2.0Ah cells for lighter duty to expanded capacity 7.5Ah batteries for extended runtime on larger properties. This flexibility allows you to tailor your battery investment to your specific needs rather than being locked into a single fixed capacity. The 5-year tool warranty provides comprehensive coverage that reflects EGO’s confidence in the build quality and durability of this model.

Frequently Asked Questions

Are battery-powered string trimmers as powerful as gas models?

Modern high-voltage battery-powered string trimmers like the 80V Greenworks and 56V EGO models deliver performance that rivals gas-powered equipment for the vast majority of residential applications. These advanced cordless trimmers handle thick weeds, dense grass, and light brush effectively. However, professional-grade gas trimmers with larger engines (28cc and above) still hold an advantage for heavy commercial use, thick overgrown vegetation, and extended runtime requirements. For typical homeowner needs, the best battery string trimmers provide more than sufficient power without the noise, emissions, and maintenance demands of gas models.

How long does the battery last on a cordless string trimmer?

Battery runtime varies significantly based on the trimmer’s voltage, the battery’s amp-hour capacity, and the density of vegetation being cut. Entry-level 20V trimmers typically provide 15 to 45 minutes of runtime per charge, while mid-range 40V to 56V models offer 30 to 60 minutes. High-capacity 80V trimmers like the Greenworks can deliver similar runtime but with noticeably more cutting power. The included battery capacity and whether you have spare batteries ready to swap will determine your total effective runtime for any given trimming session.

What is the difference between bump feed and automatic feed systems?

Bump feed systems require you to manually tap the cutting head against the ground to release additional line when it wears short. This traditional method gives you complete control over line deployment but requires practice to use effectively. Automatic feed systems like BLACK+DECKER’s AFS continuously advance line without manual intervention, ensuring uninterrupted cutting but potentially wasting line in certain conditions. Advanced systems like EGO’s POWERLOAD and WORX’s Command Feed offer push-button or on-demand line feeding that combines the precision of manual control with the convenience of automatic systems.

Can I use my string trimmer battery with other outdoor power tools?

Many string trimmer manufacturers design their battery platforms to be cross-compatible across multiple tools. BLACK+DECKER’s 20V MAX system, WORX’s 20V PowerShare platform, and EGO’s 56V ARC Lithium lineup all include a wide range of compatible tools including blowers, hedge trimmers, pole saws, lawn mowers, and more. Before investing in a cordless system, consider the other outdoor power tools you currently own or plan to purchase, and choose a platform that offers the tools you need with shared battery compatibility to maximize the value of your battery investment.

What size string trimmer do I need for my yard?

Property size and terrain complexity are the primary factors in determining the appropriate cutting swath. For small yards under a quarter acre with many landscape features, a 12-inch cutting width provides the precision needed for tight spaces and detailed edging work. Medium properties up to half an acre are well-served by 14 to 15-inch models like the EGO ST1510T or BLACK+DECKER BESTA510. Larger properties over half an acre benefit from the faster coverage of 16-inch cutting swaths found on models like the EGO ST1623T and Greenworks 80V, which reduce total trimming time significantly on larger areas.

Conclusion

Choosing the right string trimmer for your lawn care needs ultimately depends on your property size, terrain, budget, and desired features. The best string trimmers of 2026 offer options for every requirement, from the affordable corded BLACK+DECKER BESTA510 for small yards to the powerful 80V Greenworks for demanding properties. For most homeowners, the WORX WG163 delivers the ideal combination of performance, features, and value as our Best Overall pick, while the EGO POWER+ ST1623T represents the pinnacle of battery-powered trimming technology for those seeking premium features. Whatever your needs, investing in a quality string trimmer will help you achieve the clean, polished lawn edges and landscape definition that transforms your yard from ordinary to exceptional. Regular trimming maintenance keeps your landscape looking its best throughout the growing season and protects your property value by ensuring your outdoor spaces always make a strong first impression.
