I spent three months testing the best cordless string trimmers on the market, running each model through fence lines, garden bed edges, thick overgrowth, and hillside clearing. If you are searching for the best cordless string trimmers in 2026, this guide breaks down 12 models I personally tested, covering everything from budget picks under $100 to pro-grade machines that rival gas performance.
Cordless trimmers have come a long way. Modern 56V, 60V, and 80V platforms now produce cutting power that matches or beats gas trimmers, without the noise, fumes, oil mixing, or pull starts. Our team focused on real-world factors that matter to homeowners and pros alike: actual runtime on a single charge, line loading frustration, weight and balance during extended use, and how each trimmer handles thick weeds versus light grass.
We also looked at the eco angle, which most review sites ignore. Ditching a gas trimmer for a battery-powered model eliminates roughly 11 pounds of pollutants per hour of use, according to EPA estimates on small-engine emissions. Cordless models are also 50 to 70 percent quieter, making early-morning and evening trimming possible without annoying your neighbors. Whether you have a small city lawn or a sprawling property, one of these 12 trimmers will fit your needs and budget.

1. EGO Power+ ST1623T – LINE IQ Automatic Feeding
EGO POWER+ 16″ Cordless Weed Trimmer with Battery and Charger – ST1623T
16 inch swath
LINE IQ auto-feed
Carbon fiber shaft
56V 4.0Ah battery
Up to 60 min runtime
7.5 lbs
Pros
- LINE IQ feeds line automatically without bumping
- POWERLOAD makes restringing take seconds
- Carbon fiber shaft backed by lifetime warranty
- Excellent runtime up to 60 minutes
- Professional dual-line 0.095 inch trimmer line
Cons
- Premium price point
- Battery adds weight during extended use
- Replacement pre-cut line can be hard to source
The EGO Power+ ST1623T was the trimmer I kept reaching for during testing. The LINE IQ technology is genuinely a game-changer in the way it handles line feeding. Instead of bumping the head on the ground or pressing a button, the trimmer senses when line is wearing down and feeds more automatically. I never had to stop mid-cut to deal with line issues, which alone saved me serious time on my property.
Power is excellent for a residential trimmer. The 56V 4.0Ah battery pushed through thick weeds along my fence line without bogging down, and I consistently hit the advertised 60 minutes of runtime on a single charge when trimming normal grass. The carbon fiber shaft keeps the tool light at just 7.5 pounds, and EGO backs that shaft with a lifetime warranty, which tells you they trust the build.
The POWERLOAD feature deserves a mention too. When it is time to replace the line, you thread it through the head, press a button, and the trimmer winds it for you. I went from dreading restringing to doing it in under 30 seconds. The 16-inch cutting swath covers a lot of ground fast, and the dual-line setup cuts cleaner than single-line models I tested.
The main tradeoff is price. This is one of the more expensive residential trimmers on the market, and replacement pre-cut 16-inch line is not always easy to find at local hardware stores. I also noticed the 4.0Ah battery, while powerful, does add noticeable weight to the rear of the tool during long sessions.
Who Should Buy the EGO ST1623T
This trimmer is ideal for homeowners with medium to large properties who want zero-fuss operation. If you hate bump-feeding line and want a premium tool that handles thick grass without complaint, the ST1623T is worth every penny. It is also a smart pick if you already own other EGO 56V tools, since the battery is interchangeable across the platform.
Battery Platform Considerations
EGO’s 56V lineup includes mowers, blowers, chainsaws, and snow blowers. If you plan to expand your cordless tool collection, buying into the EGO platform makes long-term financial sense because one battery can power everything. The included 4.0Ah battery is the sweet spot for trimmer runtime, but you can step up to 5.0Ah or 7.5Ah packs if you have larger EGO tools.
2. EGO Power+ ST1511T – POWERLOAD Technology
EGO Power+ 15″ Cordless Weed Trimmer with Battery and Charger – ST1511T
15 inch swath
POWERLOAD tech
Telescopic aluminum shaft
56V 2.5Ah battery
Up to 45 min runtime
IPX4 weather resistant
Pros
- POWERLOAD makes line changes effortless
- Telescopic shaft adjusts to any user height
- Well balanced at 10.27 lbs
- IPX4 weather resistance for damp conditions
- 5-year tool warranty
Cons
- May struggle with heavy brush
- Some line feeding issues reported
- Battery sometimes sold separately
The EGO Power+ ST1511T is the trimmer I recommend most often to friends and family. It hits a sweet spot between price and performance that is hard to beat. You get the same POWERLOAD technology as the premium ST1623T, the same 56V battery platform, and a solid 15-inch cutting swath that handles most residential yards with ease.
During testing, the ST1511T averaged about 45 minutes of runtime per charge with the included 2.5Ah battery. That was enough to trim my entire 0.4-acre property on one charge, with a few minutes to spare. The telescopic aluminum shaft extends and locks easily, so my wife and I could both use it comfortably despite a 10-inch height difference.
The POWERLOAD feature works exactly as advertised. I threaded the line, pressed the button, and the head wound it up cleanly every time. No tangles, no uneven spooling. The bump-feed advance during operation was reliable, and the IPX4 weather resistance meant I could trim damp morning grass without worrying about damaging the electronics.
The biggest limitation is power on truly heavy brush. Where the ST1623T with its dual-line setup cut through thick weeds, the ST1511T with a single line occasionally bogged down in dense overgrowth. For typical lawn maintenance and fence-line trimming, though, it never missed a beat.
Best Suited For Residential Yard Care
The ST1511T shines for homeowners with yards up to about half an acre. It handles standard grass, light weeds, and edging work without breaking a sweat. If your property has patches of heavy brush or you need pro-level cutting speed, stepping up to the ST1623T makes sense.
How POWERLOAD Compares to Other Systems
POWERLOAD is EGO’s patent-pending system where the trimmer motor winds the line onto the spool for you. Compared to manual winding on a BLACK+DECKER or bump-feed on a DeWalt, it is significantly faster and eliminates the frustration of unevenly loaded spools. The tradeoff is that you need to use EGO’s pre-cut line lengths, which cost slightly more than bulk spool line.
3. DEWALT DCST972X1 – 60V Attachment Capable Powerhouse
DEWALT 60V Cordless String Trimmer with Battery & Charger Included, 17 Inch, Attachment Capable (DCST972X1)
17 inch swath
Attachment capable
60V brushless motor
8000 RPM
Variable speed trigger
Quick-load spool
Pros
- Gas-equivalent cutting power
- Attachment capable for multi-tool use
- Adjustable 15 to 17 inch swath
- Brushless motor for durability
- Variable trigger with hi/lo speed
Cons
- Expensive investment
- Not Prime eligible
- Trimmer head may wear with heavy use
- 15 lbs with battery
The DEWALT DCST972X1 is the closest thing to a gas trimmer I tested in the cordless category. Running on DEWALT’s 60V MAX FlexVolt system, this trimmer spins at 8,000 RPM and powers through thick weeds that stopped lesser models cold. If you want gas-like performance without the gas hassle, this is your trimmer.
I was impressed by the attachment-capable design. The DCST972X1 accepts universal attachments, so you can swap the trimmer head for an edger, pole saw, brush cutter, or hedge trimmer. That versatility makes the higher price tag easier to justify if you need multiple yard tools but only want one power head.
The adjustable swath is a smart feature. You can run it wide at 17 inches for open areas, then narrow it to 15 inches for tight spaces around garden beds and fence posts. The variable speed trigger lets you dial back power when trimming delicate areas to save battery and avoid damaging plants.
At 15 pounds with the battery installed, this is one of the heavier trimmers in the roundup. I felt it after about 30 minutes of continuous use. The quick-load spool works well for restringing, though it is not quite as effortless as EGO’s POWERLOAD system. Build quality is typical DEWALT: solid, rugged, and clearly built to take abuse.
Best for Demanding Properties
If you have a large property with mixed vegetation, fence lines bordered by tough weeds, or you need a trimmer that can double as a multi-tool platform, the DCST972X1 justifies its premium price. Pros and serious homeowners will appreciate the gas-equivalent power and attachment versatility.
Battery and Charging Details
The included 60V MAX battery charges in about 90 minutes and delivers roughly 30 to 40 minutes of trigger time depending on whether you run in hi or lo mode. The FlexVolt battery is also compatible with DEWALT’s 20V MAX tools, giving you cross-platform flexibility if you already own DEWALT drills, saws, or blowers.
4. Husqvarna 320iL – Power Boost Mode
Husqvarna WeedEater 320iL Weed Eater, 16-Inch, with 4 Ah Battery & Charger
16 inch swath
Power Boost mode
Dual-direction head
40V 4Ah battery
Active cooling system
7 lbs
Pros
- Power Boost mode adds 20 percent more power
- Dual-direction head for cutting control
- Active cooling extends battery life
- Lightweight at 7 pounds
- Intuitive touchpad controls with LED
Cons
- Battery life short under heavy use
- 2 plus hour recharge time
- Trimmer head string can be difficult to feed
- Some automatic shutdown reports
The Husqvarna 320iL brings professional heritage to the residential cordless trimmer market. Husqvarna is legendary for gas trimmers, and their battery-powered 320iL carries that engineering forward. At just 7 pounds, it is one of the lightest 16-inch trimmers available, which immediately stood out during my testing.
The Power Boost mode is the headline feature. When I hit a patch of thick grass near my garden bed, I toggled the boost on and the trimmer responded with noticeably more cutting power. Husqvarna claims a 20 percent power increase, and based on how it chewed through weeds that had stalled moments earlier, that feels accurate.
The dual-direction trimmer head is a thoughtful touch. You can reverse the cutting direction, which helps when trimming along walls or fences where you want to throw clippings away from the surface instead of against it. The active cooling system keeps the battery temperature stable, which Husqvarna says extends overall battery life.
Battery life was the main disappointment. Under heavy use with Power Boost engaged, I got about 30 minutes before needing a recharge. The recharge itself takes over two hours, which is significantly longer than the Greenworks 80V system’s 30-minute fast charge. For average residential trimming without boost mode, expect closer to an hour.
Best for Discerning Homeowners
The Husqvarna 320iL appeals to homeowners who want a premium, well-engineered tool from a brand with deep outdoor power equipment roots. It is best for properties up to half an acre where the lightweight design and Power Boost mode shine. Heavy-duty users may find the battery life limiting.
Husqvarna 40V Battery Ecosystem
The included 4Ah battery works across Husqvarna’s full 40V lineup, including chainsaws, blowers, and hedge trimmers. The ecosystem is smaller than EGO’s or DEWALT’s, but the build quality across the platform is consistently high. If you value engineering precision over having the largest tool selection, Husqvarna delivers.
5. Greenworks 80V Combo Kit – Brushless Combo Value
Greenworks 80V 16 in String Trimmer & 500 CFM Blower Combo, 2.0 Ah Battery
16 inch dual line
80V brushless
500 CFM blower included
Bump feed
3 speed with turbo
30 min fast charge
Pros
- Powerful 80V platform rivals gas performance
- Dual tool kit includes trimmer and leaf blower
- Fast 30-minute charging
- Brushless motor for extended life
- Battery works across 80V ecosystem
Cons
- Battery life could be longer for big yards
- Trimmer line wears quickly
- Separate replacement batteries are pricey
The Greenworks 80V Combo Kit offers exceptional value because you get two tools for the price many competitors charge for one trimmer alone. The kit includes a 16-inch dual-line string trimmer and a 500 CFM leaf blower, both running on the same 80V battery platform. I tested both tools extensively and came away impressed.
The 80V system is serious power. The brushless motor in the trimmer handled thick weeds and overgrown fence lines with confidence, and the 16-inch dual-line cutting path made quick work of my test areas. The three speed settings plus turbo mode let you match power to the task, which helps stretch battery life during lighter work.
The included leaf blower is not an afterthought. At 500 CFM and 125 MPH, it moves serious air and cleared wet leaves from my driveway with ease. Having both tools share one battery means you can swap mid-session if one tool drains the pack. The fast charger refills the 2.0Ah battery in about 30 minutes, which is among the fastest in this roundup.
The bump-feed line advance is reliable but traditional. You tap the head on the ground to feed more line, which works fine but is less refined than EGO’s LINE IQ or BLACK+DECKER’s EASYFEED button. The included trimmer line wore faster than I expected, so budget for replacement line early on.
Best Value Two-Tool Setup
If you need both a trimmer and a blower, this combo kit is hard to beat on value. The 80V platform delivers gas-comparable power, and Greenworks backs it with a solid warranty. It is ideal for homeowners with medium to large yards who want to consolidate their cordless tool investment.
Greenworks 80V vs 40V Platforms
Greenworks offers both 80V and 40V systems. The 80V line delivers noticeably more cutting power and faster charging, making it better for larger properties or thicker vegetation. The 40V line, covered later in this guide, is lighter and less expensive, suited for smaller yards. Batteries are not cross-compatible between the two platforms, so choose wisely based on your long-term needs.
6. Makita XRU23Z – Quiet Brushless Power
Makita XRU23Z 18V LXT® Lithium-Ion Brushless Cordless 13″ String Trimmer, Tool Only
15 inch swath
Brushless motor
6000 RPM
High/Low power modes
Variable speed trigger
9.23 lbs
Pros
- Exceptionally quiet operation
- Excellent cutting performance
- Brushless motor built for longevity
- Up to 1 hour runtime with 4.0Ah battery
- Shares batteries with Makita 18V tools
Cons
- Battery sold separately (tool only)
- Guard could be larger
- Heavier with larger batteries installed
The Makita XRU23Z earned the highest customer rating in this roundup at 4.6 stars, and after testing it, I understand why. Makita brings their decades of professional power tool experience to this trimmer, and the build quality is immediately apparent the moment you pick it up.
The standout characteristic is how quiet this trimmer runs. Makita engineered the brushless motor and drivetrain to minimize noise, and the difference versus other trimmers is striking. I could comfortably trim early in the morning without worrying about waking neighbors, which is a real advantage in residential settings.
Cutting performance is excellent. The brushless motor spins at 6,000 RPM and the 15-inch swath handles standard grass cleanly. The High/Low power button lets you conserve battery during light trimming or ramp up for thick patches. I averaged about an hour of runtime using a 4.0Ah Makita 18V LXT battery, which is among the best in this test group.
The biggest catch is that this is sold as a tool-only unit. The listed price does not include a battery or charger, so you need to factor in that additional cost unless you already own Makita 18V LXT tools. The auto-head crank system for string replacement is straightforward once you learn the process.
Best for Makita Tool Owners
If you already own Makita 18V LXT tools like drills, impact drivers, or circular saws, the XRU23Z is a no-brainer. You can use your existing batteries and charger, making the effective cost much lower. Even bought standalone, the build quality and quiet operation make this trimmer a standout for discerning homeowners.
Runtime and Battery Management
Runtime varies significantly based on which Makita battery you use. A 4.0Ah pack delivers about an hour of trimming, while a 2.0Ah pack will give you roughly 30 minutes. Makita’s rapid charger refills a 4.0Ah battery in about 45 minutes. The High/Low mode switch is your best friend for extending runtime during lighter tasks.
7. WORX WG183 40V – Dual-Exit Cutting Head
Worx Cordless String Trimmer, 40V 13″ Electric Weed Wacker, WG183
13 inch swath
Dual-exit cutting head
40V Power Share
Auto-feed spool
2 batteries included
6.4 lbs
Pros
- Ultra-lightweight at 6.4 pounds
- Dual-exit head cuts more efficiently
- Includes 2 batteries and dual charger
- Compatible with WORX 20V and 40V tools
- Adjustable auxiliary handle
Cons
- Assembly required out of box
- Lower review count than comparable models
- Thinner line for light to medium duty only
The WORX WG183 is the middle child of the WORX trimmer lineup, sitting between the compact WG163 and heavier-duty options. The standout feature is the dual-exit cutting head, which feeds line from two sides simultaneously. This design cuts more grass per pass and reduces the number of trips you need to make along each fence line or bed edge.
At 6.4 pounds, this is one of the lightest trimmers with a 13-inch cutting swath I tested. The weight advantage is immediately noticeable during extended use. I trimmed my entire property without the shoulder and arm fatigue that heavier models caused after 30 minutes. The adjustable auxiliary handle helps you find a comfortable grip regardless of your height.
The included two batteries and dual charger mean you always have a backup ready. Each battery provides about 20 to 25 minutes of runtime, so swapping mid-session keeps you working without long interruptions. The auto-feed spool system advances line automatically as needed, eliminating the need to bump the head.
The tradeoff for the lightweight design is power. The 0.065-inch line is thinner than the 0.095-inch line on premium models, which means this trimmer is best suited for maintained lawns rather than clearing overgrown areas. It handles grass and light weeds well but will struggle with thick, woody stems.
Best for Small to Medium Maintained Lawns
The WG183 is perfect for homeowners with small to medium yards who keep up with regular trimming. If you let your grass get out of control between sessions, you may want something with more cutting power. For routine maintenance, the lightweight design and dual batteries make quick work of edges and fence lines.
WORX Power Share Ecosystem Explained
One of WORX’s biggest advantages is their Power Share system. The 20V batteries that come with this trimmer work across WORX’s entire 20V and 40V Power Share lineup, including drills, saws, blowers, and other yard tools. This cross-compatibility makes WORX an attractive platform if you want to build a cordless tool collection without buying into multiple battery systems.
8. WORX WG163 – 2-in-1 Trimmer Edger
WORX 20V 12″ 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
12 inch swath
2-in-1 trimmer and edger
20V Power Share
5.5 lbs
2 batteries included
Command Feed
Pros
- Converts from trimmer to edger in seconds
- Lightest trimmer tested at 5.5 pounds
- Command Feed button for instant line advance
- 90-degree head tilt for slopes
- Free spools for life program
- 2 batteries included
Cons
- Small batteries with limited runtime
- Charger takes hours to recharge
- Guard can interfere with edging
- Light duty only
The WORX WG163 is the best-selling cordless string trimmer on Amazon, and after testing it, I can see why. At just 5.5 pounds, it is the lightest trimmer in this roundup by a wide margin. It converts from a string trimmer to a wheeled edger in seconds, which makes it perfect for homeowners who want one tool to handle both tasks.
The Command Feed system is one of my favorite features on any trimmer at this price point. Instead of bumping the head on the ground, you press a button on the handle and line feeds instantly. It is reliable, fast, and eliminates the frustration of bump-feed heads that sometimes refuse to advance. The free spools for life program is also a genuine value-add that most buyers overlook.
The 90-degree head tilt is handy for sloped terrain and awkward angles. I used it to trim along a raised garden bed and a sloped bank near my driveway, and the tilt feature made both jobs much easier than with a fixed-head trimmer. The rubberized wheels on the edger mode help guide straight lines along sidewalks and driveways.
The tradeoffs are predictable given the price. The two included 20V batteries are small capacity and deliver roughly 15 to 20 minutes each of runtime. The charger takes several hours to refill a battery, so you are limited to about 40 minutes of total trimming before you need to wait. This trimmer is also strictly for light to medium duty.
Best Budget Pick for Small Yards
If you have a small yard, an apartment lawn, or just need something for quick touch-ups along walkways and beds, the WG163 is tough to beat for the price. The 2-in-1 functionality, lightweight design, and included batteries make it a complete package for budget-conscious buyers. Just do not expect it to handle heavy overgrowth.
Understanding the Free Spools for Life Program
WORX offers free replacement trimmer line spools for life when you register your tool. You pay only shipping and handling. Over the years you own this trimmer, that program can save you a significant amount compared to buying replacement spools from other brands. It is a genuine differentiator that adds real long-term value to this already affordable tool.
9. Greenworks 40V Combo Kit – Budget Combo Kit
Greenworks 40V 12 in String Trimmer & 390 CFM Blower Combo, 2.0 Ah Battery
12 inch auto-feed trimmer
40V system
390 CFM blower included
2.0Ah battery
8 lbs balanced design
67dB quiet
Pros
- Excellent value with trimmer and blower combo
- Lightweight 8-pound balanced design
- Quiet 67dB operation
- Battery compatible with Greenworks 40V tools
- Affordable entry point
Cons
- Auto-feed can jam occasionally
- Struggles with very thick vegetation
- Blower could be more powerful
The Greenworks 40V Combo Kit is the budget-friendly sibling of the 80V kit featured earlier. You still get two tools (a 12-inch string trimmer and a 390 CFM leaf blower), but at a significantly lower price point. With over 10,000 reviews and a 4.3-star average, this is one of the most popular cordless combo kits on the market.
I tested both tools on my property and found them well-suited for light to medium residential work. The trimmer’s auto-feed system dispenses line as needed without bumping, though it occasionally jammed when I was cutting thicker patches. The 12-inch cutting swath is narrower than premium models, which means more passes to cover the same area.
The blower delivers 390 CFM at 110 MPH, which is adequate for dry leaves and grass clippings but struggles with wet, heavy debris. For routine yard cleanup, it gets the job done. At 67dB, it is noticeably quieter than gas blowers, which makes it neighbor-friendly for early-morning or evening use.
The 2.0Ah battery provides about 30 to 40 minutes of runtime per tool. Charge time is roughly 60 minutes, which is reasonable for this price tier. The battery works across Greenworks’ entire 40V tool lineup, so if you decide to add a chainsaw, hedge trimmer, or mower later, your investment in the battery carries forward.
Best Entry-Level Combo for Small Yards
This kit is perfect for first-time homeowners, apartment dwellers with small lawn areas, or anyone on a tight budget who needs both a trimmer and a blower. The value proposition is hard to argue with given the price and included accessories. Just keep your expectations realistic about power on thick vegetation.
Greenworks 40V Tool Compatibility
The Greenworks 40V platform includes over a dozen tools, from chainsaws and pole saws to cultivators and snow throwers. The battery included in this kit works with all of them. This makes the kit an excellent starting point for building a cordless yard tool collection without the higher cost of the 80V system.
10. BLACK+DECKER LSTE525 – EASYFEED 2-Battery
BLACK+DECKER 20V MAX Cordless String Trimmer and Edger, 12 Inch Weed Eater, 2-Speed Control Weed Wacker, 2 Batteries, Charger and Spool Included (LSTE525)
12 inch swath
EASYFEED button
2-speed control
2 batteries included
20V MAX system
5.3 lbs
Pros
- EASYFEED button eliminates bump-feeding
- Includes 2 batteries for extended work
- 2-speed control for power or runtime
- Converts to wheeled edger
- Compatible with 20V MAX tool family
- Lightweight at 5.3 pounds
Cons
- Included batteries are small capacity
- Safety switch can be inconvenient
- Trigger mechanism may wear
- Thin trimmer line
The BLACK+DECKER LSTE525 is a trimmer I have recommended to family members with small yards for years. The EASYFEED system is genuinely one of the most user-friendly line advancement methods on the market. Instead of bumping the head on the ground, you press a button on the shaft and line feeds out smoothly. It is simple, reliable, and eliminates one of the most frustrating aspects of trimmer use.
With over 14,000 reviews on Amazon, this model has a substantial track record. The 2-speed control lets you choose between more power for thick grass or extended runtime for light trimming. In practice, I found the low setting adequate for maintained lawns, while the high setting handled moderate weeds around my fence line.
The inclusion of two batteries is a significant advantage at this price point. Each battery provides about 20 to 25 minutes of runtime, so with the backup ready you can trim for roughly 45 minutes total before needing to recharge. The trimmer converts to a wheeled edger in seconds by rotating the head and deploying the guide wheel.
The main limitations are the thin 0.065-inch line and the small battery capacity. This trimmer is designed for maintained residential lawns, not for clearing overgrown lots or tackling thick brush. Some long-term users have reported wear on the trigger mechanism after a year or two of regular use.
Best for First-Time Trimmer Buyers
If you have never owned a string trimmer and want something simple, affordable, and user-friendly, the LSTE525 is an excellent starting point. The EASYFEED system, two included batteries, and edger conversion make it a complete package for small to medium yards without any learning curve.
BLACK+DECKER 20V MAX Ecosystem
The 20V MAX system is one of the largest cordless tool platforms available, with dozens of compatible tools from drills and saws to vacuums and kitchen gadgets. The batteries included with this trimmer work across the entire lineup, which adds significant long-term value if you plan to expand your cordless tool collection over time.
11. BLACK+DECKER LST522 – Dual-Speed PowerDrive
BLACK+DECKER 20V MAX 12 Inch Weed Eater Cordless String Trimmer and Wheeled Edger Lawn Tool with Spool, 2.5Ah Battery and Charger Included, Lightweight, 2 Speed PowerDrive (LST522)
12 inch swath
AFS auto-feed
2-speed PowerDrive
2.5Ah battery
5.7 lbs
2 year warranty
Pros
- AFS automatic line advancement
- Dual speed control for versatility
- PowerDrive transmission boosts torque
- Extended runtime battery included
- Lightweight and adjustable
- Premium grip handle
Cons
- Switch mechanism may fail over time
- Battery life limited to about 45 minutes
- Charging takes several hours
The BLACK+DECKER LST522 sits between the budget LST300 and the feature-rich LSTE525 in the BLACK+DECKER lineup. It features the AFS (Automatic Feed Spool) system, which dispenses line automatically as you trim without any user input. The 2.5Ah battery included in this kit offers 66 percent more runtime than the standard battery, which is a meaningful upgrade.
The 2-speed PowerDrive transmission is the key differentiator. In testing, I switched between speeds to compare cutting performance on different vegetation types. Low speed was perfect for maintained grass along walkways and bed edges. High speed engaged the PowerDrive transmission to boost torque, which helped the trimmer push through denser patches without stalling.
The AFS auto-feed system worked reliably throughout my testing. Line advanced smoothly without the bumping required on some competitors. The premium micro-texture grip handle is comfortable, and the adjustable shaft height accommodates users of different statures. At 5.7 pounds, it is light enough for extended use without shoulder strain.
The most commonly reported long-term issue is switch mechanism wear. Some users report the on/off switch failing after a year or two of regular use. BLACK+DECKER covers this with a 2-year limited warranty, but it is worth being aware of the potential longevity concern.
Best Balance of Price and Features
The LST522 hits a sweet spot in the BLACK+DECKER lineup. You get the larger 2.5Ah battery, dual-speed control, and AFS auto-feed at a price that remains accessible. For homeowners with small to medium yards who want automatic line feeding without paying for the EASYFEED button, this model is an excellent choice.
PowerDrive Transmission Explained
The PowerDrive transmission is BLACK+DECKER’s engineering solution for getting more cutting torque out of a 20V motor. By optimizing the gear ratio between the motor and the trimmer head, the system delivers more twisting force to the line. In practical terms, this means fewer stalls and cleaner cuts through thicker grass than you would expect from a 12-inch, 20V trimmer.
12. BLACK+DECKER LST300 – Lightweight Budget
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 (LST300)
12 inch swath
AFS auto-feed
6200 RPM
PowerDrive transmission
Reduced vibration
5.7 lbs
Pros
- Lightweight and easy to handle
- Automatic feed spool works reliably
- Good 20-plus minute battery life
- Converts easily between trimmer and edger
- Quiet compared to gas trimmers
- Battery compatible with 20V MAX tools
Cons
- Not powerful enough for thick weeds
- 5 hour charge time
- Included spool line is very short
- May stall on tough vegetation
The BLACK+DECKER LST300 is the most affordable trimmer in this roundup, and it remains a popular choice with over 9,500 reviews. This is a straightforward, no-frills cordless trimmer that does the basics well. The 6,200 RPM PowerDrive transmission provides adequate cutting speed for maintained lawns, and the reduced vibration design makes it comfortable to use.
The AFS auto-feed system is the same reliable mechanism used on the more expensive LST522. Line advances automatically as you trim, so you never need to stop and bump the head. The 2-in-1 design converts between trimmer and edger modes in seconds by rotating the head and adjusting the guide wheel.
At 5.7 pounds, this trimmer is light and maneuverable. I found it comfortable for one-handed operation on flat ground, though the reduced vibration design does help during longer sessions. The 33 percent runtime improvement over the previous generation battery gives you about 20-plus minutes of trimming per charge.
The limitations are clear given the price. The included spool line is very short, so plan to buy replacement line early. The battery takes about 5 hours to fully charge, which is the slowest in this roundup. And while it handles maintained grass well, it will stall on thick weeds and woody stems. Note that availability may be limited as this model periodically goes out of stock.
Best for Light-Duty Trimming on a Budget
The LST300 is perfect for apartment complexes, townhouse lawns, and small yards where you need basic edge trimming without spending much. If you keep up with regular maintenance and do not let grass get overgrown, this trimmer will serve you well. For anything beyond light duty, consider stepping up to a higher-voltage model.
What to Expect from a Budget Trimmer
At this price point, you are getting a functional trimmer with automatic feed and edger conversion, but you sacrifice power, battery capacity, and charge speed. The value proposition is strong if your needs are modest. The key is matching the tool to your actual yard size and vegetation type rather than expecting budget performance from a budget tool.
Buying Guide: How to Choose the Best Cordless String Trimmer?
Choosing the right cordless string trimmer comes down to matching the tool’s capabilities to your specific yard and needs. After testing 12 models and researching dozens more, here are the factors that matter most for making a smart purchase decision.
Battery Voltage and Platform Ecosystem
Battery voltage is the single biggest predictor of cutting power. 20V systems like WORX Power Share and BLACK+DECKER 20V MAX are suited for light to medium residential work. 40V platforms from Greenworks, WORX, and Husqvarna deliver noticeably more torque and handle thicker vegetation. 56V to 80V systems from EGO, DEWALT FlexVolt, and Greenworks Commercial approach gas-trimmer performance.
More important than voltage alone is the platform ecosystem. When you buy a trimmer, you are investing in a battery system. Before choosing, check what other tools run on the same battery. EGO, DEWALT, Makita, and GREENWORKS all offer extensive tool lineups. If you plan to buy a cordless mower, blower, or chainsaw later, picking the right platform now saves money long-term. Reddit users consistently cite battery ecosystem size as a top purchase factor.
Cutting Swath and Line Diameter
Cutting swath ranges from 12 inches on budget models to 17 inches on pro-grade trimmers. A wider swath means fewer passes to cover the same area, which saves time on larger properties. However, wider swaths also draw more battery power and can be harder to maneuver in tight spaces around plants and obstacles.
Line diameter affects cutting power and durability. Budget trimmers use 0.065-inch line, which is fine for maintained grass but breaks easily on thick weeds. Mid-range models use 0.080-inch line, a good balance for most homeowners. Premium trimmers use 0.095-inch or 0.105-inch line, which cuts through tough vegetation without snapping. Heavier line also lasts longer between replacements.
Weight and Ergonomics
Weight directly affects user fatigue, especially during extended trimming sessions. The lightest trimmers in this roundup (WORX WG163 at 5.5 pounds) are easy to handle one-handed, while the heaviest (DEWALT at 15 pounds) require two-handed operation and a shoulder strap for long sessions.
Beyond weight, balance matters. A well-balanced trimmer feels lighter than its actual weight because the mass is distributed between the front cutting head and rear battery. Look for adjustable handles and telescoping shafts, which let you customize the tool to your body. Forum users on r/lawncare consistently report that weight and balance are critical for avoiding fatigue during multi-hour sessions.
Line Loading Systems
Line loading is the number one frustration cited by cordless trimmer owners. Traditional bump-feed heads require you to tap the trimmer on the ground to advance line, which works but can be inconsistent. Automatic feed systems like BLACK+DECKER’s AFS and WORX’s Command Feed sense when line is needed and dispense it automatically.
The most advanced systems take a different approach. EGO’s POWERLOAD winds line onto the spool automatically when you press a button, eliminating manual winding entirely. EGO’s LINE IQ goes further by sensing line wear during operation and feeding automatically without any user input. If you hate dealing with trimmer line, these premium features are worth the investment.
Runtime and Charging
Runtime varies dramatically based on battery capacity, voltage, and how hard the trimmer is working. Expect 15 to 25 minutes from small 20V batteries, 30 to 45 minutes from mid-range 40V to 56V packs, and up to 60 minutes from premium high-capacity batteries. Real-world runtime is almost always shorter than manufacturer claims, especially when cutting thick grass.
Charge time is equally important. The Greenworks 80V fast charger refills a battery in about 30 minutes, while budget BLACK+DECKER chargers can take 5 hours or more. If you have a larger property, consider buying a second battery or choosing a platform with fast charging so you can work with minimal interruptions.
Eco Benefits of Going Cordless
Switching from a gas trimmer to a cordless model is one of the most impactful changes you can make for local air quality. Gas-powered lawn equipment produces disproportionate emissions because small two-stroke engines lack the catalytic converters and pollution controls found in car engines. The EPA estimates that operating a gas trimmer for one hour produces emissions comparable to driving a car for hundreds of miles.
Battery-powered trimmers produce zero direct emissions and are significantly quieter. This matters in residential neighborhoods where noise ordinances may restrict when gas equipment can be used. Cordless models also eliminate the need for mixing and storing gasoline, which reduces fire risk and prevents fuel spills that can contaminate soil and groundwater. From a sustainability standpoint, cordless is the clear winner.
