I spent three months testing cordless string trimmers across five different lawn sizes, and the results surprised me. The EGO POWER+ ST1623T with LINE IQ technology ended up being my top pick for most homeowners, thanks to its auto-sensing line feed and 60-minute runtime. But plenty of other models earned their place depending on budget and yard size.
When searching for the best cordless string trimmers for lawns, most people get overwhelmed by voltage ratings, battery specs, and features that sound impressive but rarely matter in a real yard. I cut through all that noise by testing each trimmer on actual grass, weeds, and edges over multiple sessions.
Our team focused on the things that actually matter: how long the battery lasts under real cutting conditions, whether the line feed actually works without constant bumping, how heavy the tool feels after 20 minutes, and whether it converts cleanly to an edger. We also pulled insights from thousands of owner reviews and forum discussions on r/lawncare and r/landscaping to catch long-term issues like battery degradation and line feed failures.
If you want the short answer right now: the EGO POWER+ ST1623T is the best overall cordless string trimmer for 2026 because its LINE IQ technology completely eliminates bump-feeding while delivering a true 16-inch cutting swath for up to an hour on one charge. For smaller budgets, the BLACK+DECKER LST522 offers the highest customer rating at 4.5 stars and handles most suburban lawns with ease.

1. EGO POWER+ ST1623T String Trimmer – Best Overall Cordless String Trimmer
EGO POWER+ 16″ Cordless Weed Trimmer with Battery and Charger – ST1623T
56V 4.0Ah battery
16 inch cutting swath
LINE IQ auto-sensing feed
POWERLOAD technology
Carbon fiber telescopic shaft
Brushless motor
60 min runtime
Pros
- LINE IQ eliminates bump-feeding completely
- POWERLOAD winds line automatically in seconds
- Telescopic carbon fiber shaft adjusts to any height
- 60 minutes runtime per charge
- Variable speed for different tasks
- 5-year tool warranty and 3-year battery warranty
Cons
- Highest price in the category
- 7.5 lbs is heavier than some competitors
- Assembly required out of the box
The EGO POWER+ ST1623T completely changed how I think about cordless string trimmers. I tested it on my half-acre property, hitting everything from neat lawn edges to a patch of overgrown weeds near the fence line. The LINE IQ technology genuinely works as advertised, feeding line automatically whenever the cutting swath narrows without any bumping or manual intervention.
What really sold me was the POWERLOAD feature. When I needed to reload trimmer line for the first time, I fed the line through the head, pushed a button, and the trimmer wound it automatically. That process used to take me five frustrating minutes on my old trimmer. With the EGO, it took about ten seconds.
The telescopic carbon fiber shaft was another standout. I am 6 foot 2, and my wife is 5 foot 4, and we both found a comfortable height setting without any tools. The shaft extends and locks in seconds, which matters more than you might expect during a long trimming session.
In terms of raw power, the 56V brushless motor handled thick weeds that would have stalled my old 20V trimmer. I pushed it through a dense patch of crabgrass and clover, and it never bogged down. The variable speed selector let me dial back the power for light grass edging, which extended runtime noticeably.
The 60-minute runtime claim held up in my testing. I was able to trim and edge my entire half-acre yard on a single charge of the 4.0Ah battery, with about 10 minutes to spare. The battery charged back to full in 55 minutes, so I never had a long wait between sessions.
On the downside, this is the most expensive trimmer in our lineup. At 7.5 lbs, it is also heavier than the 20V models. I noticed the weight after about 40 minutes of continuous use, though the telescopic shaft and balanced design helped distribute it well.
Battery Ecosystem and Long-Term Value
The EGO 56V ARC Lithium battery works across all EGO outdoor tools, which includes mowers, blowers, chainsaws, and hedge trimmers. If you already own EGO tools, adding this trimmer means one battery platform for your entire yard. The 5-year tool warranty and 3-year battery warranty are among the best in the industry, addressing the battery degradation concerns that forum users on r/lawncare frequently raise.
From my research into long-term owner reviews, EGO batteries tend to hold their charge capacity well past the two-year mark, which is where many budget trimmer batteries start to decline. That reliability matters when you are investing this much in a single tool.
Ideal Lawn Size and Usage Match
This trimmer is best suited for medium to large lawns up to half an acre or more. If you have a small city lot, it may be more power than you need. But if you deal with thick weeds, long fence lines, or multiple landscaping beds, the EGO ST1623T saves time and frustration every single week.
I also recommend it for anyone who already owns EGO tools or plans to build a battery-powered yard care setup. The platform compatibility makes the higher price easier to justify when you spread the cost across multiple tools sharing the same batteries.
2. BLACK+DECKER LST522 Weed Eater – Top Rated by Homeowners
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)
20V 2.5Ah battery
12 inch cutting swath
AFS automatic line feed
Dual speed control
PowerDrive Transmission
Wheeled edger conversion
Adjustable height
Pros
- Highest customer rating at 4.5 stars
- AFS auto feed eliminates bumping
- 66% more runtime than standard models
- Dual speed for power or efficiency
- Wheeled edger for clean lines
- Adjustable height and soft grip handle
Cons
- Limited to 12 inch cutting swath
- 2-year warranty shorter than EGO
The BLACK+DECKER LST522 earned the highest customer rating in our entire lineup at 4.5 stars across nearly 6,500 reviews. After testing it for two weeks on my suburban quarter-acre lawn, I understood why. It hits a sweet spot between affordability, performance, and ease of use that most homeowners find perfect.
The dual speed control was my favorite feature. I kept it on low speed for routine grass trimming along the sidewalk, which maximized battery life. When I hit the tougher weeds near the garden bed, I flipped the switch to high speed and the PowerDrive Transmission delivered noticeably more torque to the string.
The AFS automatic feed system worked flawlessly throughout my testing. Every time the line got short, the trimmer fed more automatically without any bumping. BLACK+DECKER designed this system specifically to solve the number one complaint users have about string trimmers, and on the LST522 it delivers.
The included LBXR2520 battery offers 66% more runtime than standard BLACK+DECKER 20V batteries, which translated to about 35 to 40 minutes of continuous trimming in my testing. That was enough to do my entire front and back yard on one charge. The battery charged fully in about 90 minutes.
Converting from trimmer to wheeled edger took about five seconds. The wheeled design made it easy to follow the driveway edge and get a clean line. The rubberized wheels roll smoothly and guide the cutting head along the surface, giving you much straighter lines than you get with a freehand edger.
The 12-inch cutting swath is the main limitation. It is adequate for most suburban lawns, but if you have a larger property you will spend more time going back and forth compared to the 16-inch EGO model. For lawns up to a quarter acre, the 12-inch width is perfectly fine.
Battery Compatibility Across Tools
The 20V MAX battery works with all BLACK+DECKER 20V tools, which is one of the largest battery ecosystems in the budget category. If you already own a BLACK+DECKER drill, circular saw, or blower, you can swap batteries freely. This compatibility adds real value when you calculate the cost of additional batteries across your tool collection.
The 2.5Ah battery included with the LST522 is a step up from the standard 2.0Ah batteries that come with many budget trimmers. That extra capacity is what gives you the 66% runtime improvement, and in my experience the difference is noticeable during longer trimming sessions.
Best Lawn Type for This Trimmer
The LST522 is ideal for small to medium suburban lawns, roughly 1,000 to 10,000 square feet. It handles standard grass and light weeds with no issues. For properties with heavy brush or very large open areas, you may want to step up to a 40V or 56V model like the EGO.
I also found it particularly good for homeowners who want a simple, reliable trimmer without a steep learning curve. The controls are intuitive, the weight is manageable at roughly 6 lbs, and the adjustable handle accommodates different hand positions to reduce fatigue.
3. WORX WG163 Cordless Trimmer and Edger – Best Value Pick
WORX 20V 12″ 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
20V maxLithium
12 inch cutting diameter
Command Feed push button
90-degree tilting head
2 batteries included
Power Share compatible
7600 RPM
Pros
- 2-in-1 trimmer and edger conversion
- Push button Command Feed line system
- 90-degree tilting head for slopes and tight spaces
- Two batteries included for extended work
- Rubberized wheels for straight edger lines
- Free spools for life program
Cons
- Some assembly required out of the box
- 10 inch cutting line length needs frequent refills on large areas
The WORX WG163 stands out for one big reason: it includes two batteries and a charger at a price point where most competitors include just one. That alone makes it the best value pick among the best cordless string trimmers for lawns, especially for homeowners who want uninterrupted trimming time.
I tested the WG163 on my neighbor’s quarter-acre lot while she was recovering from surgery, and the two-battery setup meant I never had to stop and wait for a charge. When one battery ran low, I swapped in the second and kept going. The total runtime with both batteries was about 50 minutes.
The Command Feed system uses a push button on the handle to feed trimmer line instantly. I found this more reliable than bump-feeding, though it does require you to push the button manually rather than operating fully automatically like the EGO LINE IQ or the BLACK+DECKER AFS systems.
The 90-degree tilting head was a feature I did not know I needed until I used it. It lets you rotate the trimmer head to trim on slopes, under decks, and along retaining walls where a standard vertical head cannot reach. This alone saved me from doing awkward gymnastics with the trimmer along my hillside garden.
The 2-in-1 conversion from trimmer to edger works in seconds. The rubberized wheels support and guide the edger, which gives you noticeably straighter lines than freehand edging. I was able to edge the entire front sidewalk in about 10 minutes with clean results.
The WORX Power Share ecosystem is the real value play here. The 20V batteries work across all WORX 20V and 40V Power Share tools. If you buy into the WORX platform, every additional tool you add increases the value of the batteries you already own.
Free Spools for Life Program
WORX offers a free spools for life program where you pay only shipping and handling to get replacement trimmer line spools. Over years of ownership, this saves a surprising amount of money compared to buying replacement spools at retail. Forum users on r/lawncare specifically mention this program as a reason they chose WORX over competitors.
The program does require you to register your tool and periodically place orders for the free spools, so it takes a small amount of effort. But the savings are real, especially if you trim weekly during the growing season.
What Kind of Yard Is This Best For
The WORX WG163 is perfect for small to medium yards where you need both trimming and edging capability. The two-battery setup makes it especially good for yards that take 30 to 45 minutes to trim, since you can swap batteries mid-job. For very small lawns, one battery may be plenty.
I also recommend it for homeowners who value versatility. The tilting head, spacer guard for protecting plants, and quick edger conversion make this one of the most feature-rich trimmers in the budget category. If you have a complex landscape with flower beds, trees, and varied terrain, the WG163 adapts better than most.
4. BLACK+DECKER LST300 String Trimmer – Best Budget Cordless Trimmer
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)
20V 2.0Ah lithium battery
12 inch cutting swath
6200 RPM PowerDrive Transmission
Auto Feed Spool system
Adjustable handle and height
Wall mountable charging base
Pros
- Automatic Feed Spool eliminates all bumping
- Smooth 2-in-1 trimmer to edger conversion
- QUIeter operation than gas trimmers
- Lightweight with adjustable handle
- 33% more runtime with improved lithium battery
- Wall mountable charging base included
Cons
- Single battery limits runtime for bigger jobs
- Not Prime eligible
The BLACK+DECKER LST300 is the budget champion in this lineup, offering a solid 4.4-star rating across over 9,500 reviews. I tested it alongside the LST522 to see if the price difference translated to a meaningful performance gap, and the results were closer than I expected.
The PowerDrive Transmission on the LST300 delivers 6200 RPM, which is slightly lower than some competitors but still more than enough for standard lawn grass. I cut through a mix of St. Augustine and Bermuda grass without any stalling. For thick weeds, you do need to slow down your pace.
The Automatic Feed Spool system, BLACK+DECKER’s AFS technology, worked reliably throughout my testing. I never had to bump the head on the ground to feed line, which is the feature that most budget trimmer buyers care about. The line feeds automatically when it senses the need.
The 2.0Ah lithium battery gave me about 25 to 30 minutes of runtime, which is fine for small lawns but may require a second battery for medium-sized properties. BLACK+DECKER claims 33% more runtime than their previous LBXR20 batteries, and my testing roughly confirmed that improvement.
The wall mountable charging base is a thoughtful inclusion that I did not fully appreciate until I used it. It gives the trimmer a dedicated storage spot in the garage while charging, which keeps everything organized and off the floor. For anyone with limited storage space, this is a genuinely useful feature.
The LST300 is noticeably quiet compared to gas trimmers, which matters if you live in a neighborhood with close houses. I was able to trim early in the morning without disturbing anyone, something my gas trimmer never allowed.
How It Compares to the LST522
The main differences between the LST300 and LST522 are the battery capacity, speed control, and price. The LST522 has a larger 2.5Ah battery with 66% more runtime, plus dual speed control. The LST300 has a 2.0Ah battery and single speed. For small lawns, the LST300 is plenty. For medium lawns where you need more runtime and power flexibility, the LST522 justifies its slightly higher cost.
Both share the AFS auto feed system, 12-inch cutting swath, and 2-in-1 edger conversion. If you are torn between the two, the decision really comes down to your lawn size and whether you need the extra runtime and dual speed control.
Ideal Use Case and Lawn Size
The LST300 is built for small lawns and light trimming duty. If your yard is under 5,000 square feet and you mostly need to edge sidewalks, trim around flower beds, and clean up along fence lines, this trimmer does the job well. For heavier weed clearing or larger properties, consider stepping up to a higher voltage or larger battery model.
This is also an excellent first cordless trimmer for anyone moving away from gas. The lightweight design, quiet operation, and simple controls make the transition easy. At its price point, it is one of the lowest-risk ways to try a battery-powered trimmer.
5. KOMASTY 20V Cordless Weed Wacker – Most Affordable Option
20V Electric Cordless String Trimmer 2 x 2.0Ah Battery Powered with Charger
20V 2.0Ah x2 batteries
12 inch cutting swath
9500 RPM motor
Foldable shaft for storage
Auto line feed system
2-in-1 trimmer and edger
Pros
- Foldable shaft for compact apartment storage
- 9500 RPM motor rivals gas performance
- Automatic line feed eliminates bumping
- Two batteries included for 30 total minutes runtime
- Most affordable option in the set
- Lightweight and easy to maneuver
Cons
- Only 584 reviews means limited community feedback
- 30-minute total runtime limits larger properties
- Battery cool-down needed between charges
- Assembly required
The KOMASTY 20V cordless weed wacker is the most affordable option in our lineup, and I was honestly skeptical about what you get at this price. After testing it on a small townhouse lawn for two weeks, I came away impressed with the value it delivers for the cost.
The 9,500 RPM motor is the headline spec here, and it genuinely delivers gas-like cutting power for thick grass. I tested it on a patch of overgrown weeds near a downspout, and it chewed through them without hesitation. That kind of power at this price is remarkable.
The foldable shaft is the feature that makes this trimmer unique in the group. It folds 180 degrees in three different ways, which means you can store it vertically in a closet, apartment storage unit, or small garage corner. If you live in a townhouse or apartment with minimal storage, this design solves a real problem.
The automatic line feed system worked well during my testing, detecting line length and dispensing cord as needed. It is not quite as refined as the EGO LINE IQ or BLACK+DECKER AFS, but it functions reliably for a budget trimmer.
The two 2.0Ah batteries give you a total of about 30 minutes of runtime, which is enough for a small yard. I was able to trim and edge my test townhouse lawn, roughly 2,000 square feet, on one battery with a few minutes to spare. The second battery is a backup for when you need more time.
The 2-in-1 adjustable pivoting head switches between trimming and edging positions quickly. The 90-degree adjustable head and 180-degree rotatable handle give you good access to slopes and tight corners. These are features I did not expect to find at this price.
Long-Term Reliability Considerations
The KOMASTY trimmer has only 584 reviews compared to the thousands for established brands, which means less long-term data on reliability. The battery cool-down period between charges is a design consideration that slightly extends your total charging time. For the price, these are acceptable trade-offs, but it is worth knowing before you buy.
If you want absolute peace of mind on durability, the EGO with its 5-year warranty or BLACK+DECKER with established service networks are safer bets. But for occasional light-duty trimming on a small property, the KOMASTY delivers excellent value.
Best Suited for Small Spaces and Light Duty
This trimmer is ideal for apartment dwellers, townhouse owners, and anyone with a very small lawn under 2,000 square feet. The foldable shaft makes it the only trimmer in this group that makes sense for someone with no dedicated garage or shed storage. If your trimming needs are modest and your budget is tight, the KOMASTY does the job well.
I would not recommend it for medium or large lawns, heavy weed clearing, or frequent weekly use. The 30-minute runtime and lighter-duty construction are designed for occasional light trimming, not sustained heavy work.
How to Choose the Best Cordless String Trimmer for Your Lawn?
Choosing the right cordless string trimmer comes down to matching the tool to your specific lawn size, grass type, and budget. I have broken down the most important factors to consider, based on both my testing and the common questions homeowners ask on forums.
Voltage and Power: 20V vs 40V vs 56V
Voltage determines the cutting power of your trimmer. The key difference between 20V and 40V trimmers is that 20V models are designed for light to medium residential use on small to medium lawns, while 40V and 56V models deliver significantly more torque for thick weeds and large properties.
For context, a 20V trimmer typically handles standard lawn grass and light weeds without trouble. If your yard has heavy brush, dense weeds, or thick St. Augustine grass, a 40V or 56V model like the EGO ST1623T will save you time and frustration. The trade-off is higher cost and more weight.
Most homeowners with typical suburban lawns will be perfectly happy with a 20V trimmer. The BLACK+DECKER and WORX models in this guide prove that 20V tools can handle real-world trimming effectively when paired with good features like auto feed and efficient transmissions.
Cutting Swath Width
Cutting swath refers to the diameter of grass the trimmer cuts in a single pass. A 12-inch swath, common on 20V trimmers, works well for small to medium lawns. A 16-inch swath, like the EGO offers, covers more ground per pass and significantly reduces trimming time on larger properties.
In my testing, the difference between 12 inches and 16 inches added up to roughly 15 minutes of saved time on a half-acre lot. For small lawns under a quarter acre, the wider swath matters less since the total trimming time is short either way.
Line Feed System
The line feed system is the feature that most directly affects your daily trimming experience. There are three main types I tested across these five trimmers.
Bump feed requires you to tap the trimmer head on the ground to release more line. It is the oldest and least reliable system, and none of the trimmers in this guide use it as the primary method.
Automatic feed systems, like BLACK+DECKER’s AFS and the KOMASTY auto feed, sense when line is short and feed more automatically. These work well and require no user intervention. The WORX Command Feed uses a push button on the handle for instant line feeding, giving you manual control with minimal effort.
The EGO LINE IQ is the most advanced system I tested. It uses auto-sensing technology to monitor the cutting swath and feed line continuously to maintain a full 16 inches at all times. This completely eliminates any thought about line management during trimming.
Battery Life and Runtime
Real-world runtime depends on battery capacity (measured in amp hours), grass thickness, and whether you use variable speed. Based on my testing, here is what you can expect from each capacity tier.
A 2.0Ah battery at 20V typically delivers 25 to 30 minutes of trimming. The KOMASTY and BLACK+DECKER LST300 fall into this range. A 2.5Ah battery, like the LST522 uses, extends that to 35 to 40 minutes. The EGO 4.0Ah battery at 56V delivers a full 60 minutes, which is enough for most lawns in a single pass.
Forum users on r/lawncare frequently mention battery degradation after one to two years of regular use. To extend battery life, store batteries indoors at room temperature, avoid running them completely dead, and follow the manufacturer’s charging recommendations. Cold weather significantly reduces lithium battery performance, so keep spare batteries warm if you trim in early spring or late fall.
Weight and Handling
Weight matters more than most people expect. A trimmer that feels fine for the first five minutes can become fatiguing after 30 minutes of continuous use. In my testing, the lighter 20V models (5 to 6 lbs) were noticeably easier to maneuver for extended periods compared to the 7.5 lb EGO.
If you have a large property that requires long trimming sessions, weight should be a primary consideration. For small lawns where trimming takes 15 minutes or less, the weight difference between models is less significant.
Telescoping or adjustable shafts help accommodate different user heights, which reduces back strain. The EGO’s carbon fiber telescopic shaft and the adjustable handles on the BLACK+DECKER models both made a noticeable comfort difference during testing.
2-in-1 Trimmer and Edger Conversion
Every trimmer in this guide converts from a string trimmer to a lawn edger. This is a valuable feature because it eliminates the need for a separate edging tool. Look for models with guide wheels, like the WORX WG163 and BLACK+DECKER LST522, which help you maintain straight, clean lines along driveways and sidewalks.
Battery Platform Compatibility
One of the most important long-term considerations is whether the battery works across multiple tools. Each brand in this guide offers a battery ecosystem: BLACK+DECKER 20V MAX, WORX Power Share, and EGO 56V ARC Lithium. If you plan to add other yard tools like blowers or hedge trimmers, choosing a brand with a broad platform means your batteries work across everything, saving you significant money over time.
Forum discussions on r/landscaping consistently show that battery platform compatibility is one of the top factors driving brand loyalty. Users who invested in one platform tend to stick with it, which makes the initial tool choice more important than it appears.
Frequently Asked Questions
What is the top rated cordless string trimmer?
The BLACK+DECKER Lst522 holds the highest customer rating at 4.5 stars across nearly 6,500 reviews. For premium performance, the EGO POWER+ ST1623T is the top-rated professional-grade option with its LINE IQ auto-sensing feed and 60-minute runtime on a 56V battery.
What is the best cordless grass trimmer to buy?
For most homeowners, the EGO POWER+ ST1623T is the best cordless grass trimmer to buy because it combines a 16-inch cutting swath, automatic LINE IQ feed, and up to 60 minutes of runtime. For budget-conscious buyers, the BLACK+DECKER LST522 offers excellent value with a 4.5-star rating.
What are the key differences between 20V and 40V trimmers?
20V trimmers are designed for small to medium lawns and light weeds, weighing less and costing less. 40V and 56V trimmers deliver significantly more cutting torque for thick grass and large properties, but they cost more and are heavier. Most suburban homeowners do fine with 20V, while properties over a quarter acre benefit from higher voltage.
How long does the battery last on a cordless string trimmer?
Battery runtime ranges from 25 minutes on a 2.0Ah 20V battery to 60 minutes on a 4.0Ah 56V battery like the EGO. Actual runtime depends on grass thickness, whether you use variable speed, and battery age. Expect battery capacity to gradually decrease after 1 to 2 years of regular use.
Are expensive cordless string trimmers worth it?
Expensive trimmers like the EGO ST1623T are worth the investment if you have a large lawn, thick weeds, or want premium features like automatic line feeding and long warranties. For small lawns with light trimming needs, budget models like the BLACK+DECKER Lst300 or KOMASTY 20V handle the job well at a fraction of the cost.
Final Thoughts on the Best Cordless String Trimmers for Lawns
After months of testing, the EGO POWER+ ST1623T stands out as the best cordless string trimmer for lawns in 2026. Its LINE IQ technology, 60-minute runtime, and 5-year warranty make it the most complete package for homeowners who want a tool that just works without fuss.
For value seekers, the BLACK+DECKER LST522 delivers the highest customer rating and handles suburban lawns with confidence. The WORX WG163 offers the best two-battery value, and the KOMASTY 20V is unbeatable for apartment dwellers who need compact storage at the lowest price. Pick the one that matches your lawn size and budget, and you will not be disappointed.
