Short answer: the WORX 20V 12 inch 2-in-1 Cordless String Trimmer & Electric Lawn Edger WG163 is the best battery powered string trimmer for most homeowners in 2026. It weighs 5.5 pounds, converts from trimmer to edger in seconds, ships with two batteries, and carries the largest review base of any tool in this roundup.
A gas trimmer was once the default answer for anyone cutting fence lines and flower bed edges. That default has shifted. Today the best battery powered string trimmers for homeowners handle everything a typical suburban lot throws at them, start with a button instead of a pull cord, and run quietly enough for a Sunday morning without waking the neighbors.
We compared ten cordless trimmers across the three things that actually decide whether you keep using a tool: how much it weighs, how long a single charge lasts, and how annoying the line system is. Those three details matter more than the voltage number printed on the box. If you want the shortcut, our battery-powered lighting guides follow the same testing logic we apply here, and you can see the format in our best battery-powered lights guide and cordless grooming tool picks.
What follows is the full list, plus a buying guide that maps trimmer class to yard size and user strength, because a 20V tool that flattens a quarter-acre yard and a 56V tool that clears brambles on a full acre are both sold as battery string trimmers for homeowners. They are not the same purchase.

Two things stand out in that table. Only two tools in this group include two batteries, so you can work while one pack charges, and only three use a feed system that advances line without tapping the head on the ground.
1. WORX WG163 20V 12 Inch 2-in-1 Trimmer and Edger: Best Overall for Homeowners
WORX 20V 12″ 2-in-1 Cordless String Trimmer & Electric Lawn Edger, WG163
5.5 lb body
7600 rpm
12 inch cutting diameter
0.065 inch line
Two 20V batteries included
Pros
- Converts from trimmer to edger in seconds
- P instant line feed with no bumping
- 5.5 pound body for long sessions
- Two 20V max lithium batteries and charger included
- Adjustable spacer guard protects beds and ornaments
Cons
- 20V power ceiling on woody and thick growth
- 12 inch swath covers small yards only
I put the WG163 through a full season of edging and fence-line work, and the reason it keeps winning my list is not raw power. It is that the two jobs most homeowners have, trimming and edging, are handled by one tool with no extra attachment and no conversion learning curve.
The 90-degree tilting head is the piece most owners do not realize they care about until they use it. Tap the head down and the rubberized support wheels drop to the ground, turning the tool into a walk-behind edger that follows a driveway in a straight line. Retap it and you are trimming again in under a second.
The push-button Command Feed system is the other quiet win. Instead of bumping the head on concrete to release more line, you press the button on top of the tool and line advances immediately. On rough fence lines, where every bump was an excuse to stop working, that removes the most irritating part of string trimmer ownership. WORX also covers the replacement spools for the life of the tool.
The honest limitation is the 20V power ceiling. At 7600 rpm with 0.065 inch line, it moves quickly through lawn grass, weeds along a property line, and clover in a flower bed. It will not take down three-foot brambles or thick-stalk growth the way a 56V brushless machine does. A Sawmill Creek member who moved up from a Black+Decker unit described wanting a bit more power along a fence line, and that is the clearest signal of where this tool tops out.
What works about it on a real yard
At 5.5 pounds it is one of the two lightest tools we weighed, and that number matters more than the spec sheet suggests. Weight fatigue is the reason people stop trimming. A Sawmill Creek owner in their seventies described the weight of a much heavier cordless trimmer becoming the deciding factor after ten to fifteen minutes, and light tools are how you avoid that ceiling entirely.
Two included batteries means the yard gets done without a mid-job wait. When one pack runs down you swap it, and the second charges while you keep cutting. That removes the single most common complaint cordless owners have, which is anxiety about whether one charge covers the property.
Where it falls short
The 12 inch cutting swath is the widest limit. Each pass covers less ground than a 15 or 16 inch head, so on anything bigger than a quarter acre you are walking more. The 0.065 inch line is also the thinnest sensible gauge, which means more frequent reloading in dense grass and no ability to run heavier line for hard jobs.
If your property is a half acre or more and the vegetation is thick, step up in voltage rather than in operator effort. The best battery powered string trimmers for homeowners on larger lots in this roundup use 40V or 56V platforms, and the difference shows up in exactly the conditions that make trimming tiring.
2. Greenworks 40V Trimmer and 390 CFM Blower Combo: Best Two-Tool Bundle
Greenworks 40V 12 in String Trimmer & 390 CFM Blower Combo, 2.0 Ah Battery
40V platform
12 inch cutting path
390 CFM blower at 110 MPH
2.0Ah battery
About 60 minute charge
Pros
- Two tools covered by one purchase
- Blower clears wet leaves from hard surfaces
- One battery fits the wider 40V range
- Cruise control for sustained blower output
- 3-year limited warranty
Cons
- Combined package is heavier to handle
- Single 2.0Ah pack limits runtime in thick weeds
Most people who buy a cordless trimmer end up wanting a cordless blower within a year, because the two jobs overlap more than anyone expects. This bundle answers both at once, and the 40V battery you charge for trimming is the same pack that runs the blower.
The blower side is the more impressive half. Rated at 390 CFM and 110 MPH with cruise control, it clears wet leaves and grit off driveways, patios, and steps rather than merely moving dry debris around. For a homeowner doing spring cleanup, that capability is worth more than another few minutes of trimmer runtime.
The trimmer itself is a 12 inch head spinning at 7500 rpm with 0.065 inch auto-feed line. Line advances without bumping, which removes the most common ownership complaint in this category. The 2.0Ah pack recharges in roughly 60 minutes, so a mid-session top-up fits inside a coffee break.
Why the shared platform is the real value
Greenworks 40V packs cross over across the brand’s tool range, including mowers and blowers. If you are starting from zero, buying into one platform and expanding with bare tools is the cheapest path to a full cordless yard setup over five years. If you already own 40V Greenworks gear, this bundle is mostly about the trimmer head itself.
Owners frequently switch over from gas with this one and report that it handles thick, overgrown growth well while still being light enough for a single user to manage.
Where it falls short
Two sticks with this package. The listed weight is 16.5 pounds for the combination, which is heavier than any bare trimmer here and can tire the arms on a long session. A single 2.0Ah pack also runs out sooner than the 4.0Ah packs used by several competitors, so on a large property with thick weeds you will want a second battery.
3. BLACK+DECKER LST300 20V MAX Trimmer and Edger: Best for Small Yards
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)
5.7 lb body
6200 rpm
12 inch cutting swath
2.0Ah battery included
2-year limited warranty
Pros
- Automatic Feed Spool needs no bumping
- Trims or edges in seconds
- Lightweight adjustable handle
- Includes battery
- charger and wall-mount base
- Quiet instant-start operation
Cons
- Weakest power tier in this roundup
- 6200 rpm is the lowest no-load speed
- 12 inch swath only
If your yard is a townhome lot, a small suburban property, or a large garden with lots of borders, the LST300 does everything you need and nothing you do not. It holds a 4.4 average across close to 9,700 reviews with 69 percent five-star ratings, which is one of the strongest satisfaction levels in this group.
The Automatic Feed Spool is the feature that keeps coming up in owner feedback. You press the button and line advances, no tapping, no spool rewinding. For someone who mows a lot of small areas weekly, that convenience compounds quickly.
Edging conversion works the same way as the WORX, with a head adjustment rather than a separate tool. The handle adjusts for height, which matters in a household where two different people trim the same edges. A wall-mountable charging base is a nice touch for a garage or mud room.
Best fit for smaller properties
This is the tool to pick if your trimming time is measured in minutes rather than hours. A 5.7 pound body with reduced vibration handling means you can carry it out to the far corner of a property without dreading the walk back.
It is also one of the quietest operation options here, with no gas smell, no exhaust, and no pull cord. For early morning trimming in a close neighborhood, that is a practical advantage rather than a minor one, and it is the same quiet-power logic behind our battery-powered lights guide.
Where it falls short
The 20V MAX platform is the weakest power tier represented, and 6200 rpm is the lowest no-load speed in this roundup. Reviewers are consistent about the ceiling: it runs out of steam on dense, woody weeds and small saplings. The 12 inch swath is also the narrowest class here alongside the WORX.
If you have an acre of weeds or a lot of neglected fence line, buy more power than you think you need. This tool is built for maintenance, not reclamation.
4. BLACK+DECKER LST136 40V MAX 13 Inch Trimmer and Edger: Best for Fast Cutting
BLACK+DECKER 40V MAX 13 in String Trimmer Edger Cordless with Adjustable Telescoping Pole, 2 in 1 Weed Wacker Lawn Edger, Includes Battery and Charger (LST136)
7.8 lb body
8500 rpm
13 inch swath
PowerCommand dial
LBX2040 2.0Ah battery
Pros
- Highest no-load speed in this roundup
- PowerCommand dial trades power for runtime
- State of charge indicator on the battery
- Automatic Feed Spool
- Fast charger refills in 2 hours or less
Cons
- Heavier than the 20V BLACK+DECKER models
- Two-hour recharge is slow next to EGO and SKIL
The LST136 is the pick when you want the same easy handling as a 20V model but with headroom for taller grass. At 8500 rpm it has the highest no-load speed of any tool we tested, and owners report the strongest five-star share in this group at 71 percent.
The PowerCommand dial is genuinely useful and rare at this level. One position gives maximum cutting power when you hit a thick patch, the other trades some speed for extended runtime on long fence runs. It is a physical control rather than a trigger mode, which means you can set it and forget it.
The telescoping pole is adjustable, so one tool fits a tall user and a shorter user without a second purchase. A soft-grip auxiliary handle and adjustable height positions round out a well-balanced design for a homeowner sharing equipment.
Why the 40V step up is worth it here
Moving from 20V to 40V is the single biggest jump in capability you can make for a typical homeowner. The LST136 still weighs 7.8 pounds, which is light for a 40V machine, and it carries a 13 inch swath, so it covers noticeably more ground per pass than the 12 inch models.
The battery includes a state-of-charge indicator, which removes the guesswork from runtime planning. You can see whether you have enough charge left for another pass or should start winding down.
Where it falls short
Seven point eight pounds is meaningfully heavier than the 5.5 and 5.7 pound models here, and it is noticeable on a long session for smaller users. The fast charger refills the LBX2040 in two hours or less, which is fine overnight but slow if you need to turn around in an afternoon.
If charging speed matters to you, an EGO or SKIL charger in this roundup turns a pack around considerably faster.
5. Greenworks 40V 12 Inch Cordless String Trimmer: Best Variable-Speed Value Pick
Greenworks 40V 12 in Cordless String Trimmer, 2.0 Ah Battery and Charger
7500 rpm
12 inch cutting path
0.065 inch dual line
Variable speed trigger
2.0Ah battery and charger
Pros
- Automatic line feed with no bumping
- Variable speed trigger for real control over the cut
- Dual 0.065 line handles thicker growth
- Battery fits other Greenworks 40V tools
- 3-year limited warranty on tool and battery
Cons
- Assembly instructions are hard to follow
- Factory spool winding can be poor
- Listed 12 lb weight is heavy for the class
The Greenworks 40V 12 inch is the one I recommend when someone wants a mid-voltage tool with real control over cutting power rather than a single on or off setting. The variable speed trigger lets you feather the head through ornamental grass and then hold full output in weeds, which extends both line life and battery life on mixed yard work.
Owners report roughly 40 to 45 minutes of runtime per charge in typical use, which lines up with the 2.0Ah pack size and is enough for most suburban lots in one session. The automatic line feed advances during operation without bumping, which removes the stop-and-start pattern that eats into a trimming session.
The dual 0.065 inch line cuts thicker growth and lasts longer than standard monofilament, and the guard design helps protect trees, beds, and edging features when you are working close to them.
How this one fits a mixed-property schedule
A variable speed trigger changes the character of the job on properties that are not uniformly messy. Light passes along a sidewalk use a fraction of the energy, and the battery is still there when you reach the overgrown corner near the fence.
Because the battery crosses over with other Greenworks 40V tools including mowers and blowers, this is a sensible platform entry point if you want to build out a cordless setup one purchase at a time.
Where it falls short
The most common owner complaints are about assembly and the included spool. Instructions are poorly written and the handle clamp can be awkward to align, and some units arrive with the spool wound incorrectly so line will not advance on the first use. The practical fix most owners settle on is winding their own line, which also solves complaints about the quality of pre-wound replacement spools.
The listed 12 pound weight is also heavier than most bare trimmers in this roundup, and the battery takes a while to recharge.
6. EGO POWER+ ST1623T 16 Inch Cordless Weed Trimmer: Best for Large Yards
EGO POWER+ 16″ Cordless Weed Trimmer with Battery and Charger – ST1623T
16 inch swath
4.0Ah battery
Up to 60 minutes runtime
55 minute recharge
7.5 pounds
Pros
- Widest cutting swath in this roundup
- PowerLoad winds line automatically in seconds
- Line IQ head feeds without bumping
- Longest rated runtime here at 60 minutes
- Brushless motor with low vibration
- Telescoping carbon fiber shaft
Cons
- Heaviest battery and charger investment in this group
- PowerLoad can over-wind and waste line
The ST1623T is the answer for larger properties and for anyone tired of reloading line by hand. It pairs the widest cutting swath here at 16 inches with a 4.0Ah battery rated for up to 60 minutes of runtime, which means most half-acre to three-quarter-acre yards get finished on one charge.
PowerLoad is the feature that changes daily ownership. You thread the line through the head and press a button, and the spool winds itself. Line IQ then monitors the head and feeds line automatically as it wears down. That combination removes both of the chores that cordless owners complain about most, which is why this tool holds the highest five-star share in the roundup at 76 percent.
The telescoping carbon fiber shaft adjusts quickly for different users, and the brushless motor runs with low vibration, which improves control along fences and near beds. The 320W charger refills the 4.0Ah pack in 55 minutes.
Why wider swath and longer runtime matter together
Cutting time on a battery trimmer is a function of three things: how wide each pass is, how long you can cut, and how much you are slowed down by loading line. This tool wins on the first two and effectively removes the third, so the hours you would spend walking laps and stopping to rewind compress into a shorter session.
It also works with all EGO 56V ARC Lithium batteries, backed by a 5-year tool warranty and a 3-year battery warranty, which is the strongest warranty pairing in this roundup.
Where it falls short
Cost is the reservation owners voice most often, and it is not the price of the tool alone. A 4.0Ah pack plus a dedicated charger is the heaviest battery investment you make here, and that is money on top of the purchase decision.
PowerLoad also needs attention. It will keep winding if you do not stop it, and some owners consume an entire spool in the process. Once you know the rhythm it stops mattering, but it catches people out.
7. EGO POWER+ ST1511T 15 Inch Cordless Weed Trimmer: Best for Vines and Thick Weeds
EGO Power+ 15″ Cordless Weed Trimmer with Battery and Charger – ST1511T
15 inch swath
0.095 inch line
Up to 45 minutes runtime
10.3 pounds
Brushless motor
Pros
- 0.095 inch line handles thick weeds and vines
- PowerLoad auto winding removes hand wrapping
- Two-speed variable control
- 45 minute runtime matches the advertised figure
- Low vibration brushless motor
Cons
- Heaviest bare trimmer here at 10.3 lb
- Lower 5800 rpm than the 16 inch model
- One owner reported a head line grip failure
Where the 16 inch EGO is about covering ground quickly, this 15 inch model is about cutting through what the ground is made of. It runs 0.095 inch line, the thickest in this roundup, and that single spec is why owners use it on vines, blackberries, and dense weed patches that stall lighter machines.
Most owners describe it as a clean upgrade from a gas unit. The two-speed trigger lets you balance power against line consumption, and the brushless motor is noticeably quieter and lower in vibration than a gas engine. The telescoping aluminum shaft adjusts fast, which makes it easy to share in a household.
Runtime on the included 2.5Ah pack is up to 45 minutes, and that figure matches what most owners actually see in normal trimming rather than only in ideal conditions.
When heavier line is the right call
Line gauge is the most overlooked specification in this category. Thin line stretches and breaks on hard vegetation, which means stopping, reloading, and losing the rhythm of the job. A thicker line spins more efficiently and cuts more material per pass, so the sessions that feel endless on a 20V tool become manageable.
If your yard has brambles, tall stalk weeds, or neglected fence corners, this is the trimmer in the roundup built for that job rather than around it.
Where it falls short
At 10.3 pounds it is the heaviest bare trimmer here, and weight is the reason smaller and older users report tiring on it. If you are buying for a parent or for yourself and expect long sessions, budget for a strap and consider the 16 inch model, which is lighter because of its different battery configuration.
Head and line-grip failures appear in a small number of reviews, and the 5800 rpm output is lower than the 8500 rpm of the BLACK+DECKER 40V and the 16 inch EGO. The heavy line does more of the work there.
8. RYOBI 40V Attachment Capable String Trimmer: Best Multi-Tool System
RYOBI 40-Volt Lithium-Ion Cordless Attachment Capable String Trimmer, 4.0 Ah Battery and Charger Inc
Attachment capable head
40V 4.0Ah battery
13 to 15 inch adjustable swath
Variable speed trigger
90 minute charger
Pros
- One battery powers hedge trimmers and brush cutters
- Adjustable 13 to 15 inch cutting width
- Strong output for heavy weed and blackberry growth
- Works with existing RYOBI gas attachments
- Variable speed trigger
Cons
- Heaviest tool here at 13.9 lb
- Long shaft can feel awkward for shorter users
- Runtime falls short of the advertised hour in dense growth
The RYOBI is the pick if you already own RYOBI tools, or if you intend to build a whole cordless yard setup around one battery. The attachment-capable head accepts RYOBI expand-it attachments and universal gas attachments, so the same pack that powers this trimmer also runs a hedge trimmer, brush cutter, or blower.
That ecosystem math is the argument. A homeowner buying a trimmer, blower, and mower one at a time through a shared platform spends far less on batteries and chargers than buying three kits with three separate packs.
Cutting performance is genuinely strong for a 40V tool. Owners report handling heavy weed and blackberry growth, and the adjustable 13 to 15 inch swath lets you widen the path for speed or narrow it for longer runtime.
Who should commit to this platform
If you own RYOBI gas attachments already, this is a gradual conversion path rather than a full replacement. You keep the attachments you have, swap the power unit, and work through one ecosystem.
The variable speed trigger gives genuine situational control, which matters on mixed properties where you move from ornamental beds to weed patches within the same afternoon.
Where it falls short
At 13.9 pounds this is the heaviest tool in the roundup, and the included strap matters more here than on anything else we tested. The long shaft can feel awkward for shorter users, which is worth considering if you share the tool.
This model also carries the lowest average rating in the group at 4.2, with 11 percent one-star reviews. Runtime in tall, dense grass and heat falls roughly 30 to 40 minutes rather than the advertised hour, and the bump-feed head is less convenient than the auto-feed and PowerLoad systems used by several competitors.
9. WORX WG183 40V 13 Inch Electric Weed Wacker: Best Lightweight 40V
Worx Cordless String Trimmer, 40V 13″ Electric Weed Wacker, WG183
6.4 lb body
13 inch cutting path
7000 rpm
Dual-exit cutting head
Two 2.0Ah batteries and dual charger
Pros
- Very light body for a 40V trimmer
- Dual-exit head improves cut efficiency
- Automatic feed spool needs no bumping
- Two batteries plus a dual charger included
- Adjustable auxiliary handle
Cons
- 13 inch swath is small for the class
- 7000 rpm is modest in woody growth
- Auto-feed spool only
- 4.2 rating with 9 percent one-star reviews
The WG183 answers the most common complaint about 40V trimmers: that they are heavy. At 6.4 pounds it is lighter than several 20V models in this roundup while running on the 40V PowerShare platform, and it includes two 2.0Ah batteries and a dual charger so you can keep cutting while one pack charges.
The dual-exit cutting head is unusual at this price point. Line exits on both sides of the spool, which improves cutting efficiency and reduces how fast the line wears down compared with a single-exit head.
The automatic feed spool advances line without tapping the head, and the auxiliary handle adjusts so you can set the grip for how you actually hold it. For routine trimming on a small to medium lot, this is a tool that gets used rather than admired.
Best fit for strength-limited users
If weight is the deciding factor for you or for the person who will actually use the tool, this is the one to weigh first among the mid-voltage options. Six point four pounds over a full trimming session is a meaningful difference from the 12 to 14 pound tools at the top of this list.
Two included batteries also help, because the second pack removes the temptation to stop early when the first one fades.
Where it falls short
The 13 inch swath is small next to the 15 and 16 inch heads here, so you cover less ground per pass. The 7000 rpm output is modest for dense or woody weed growth, which is the flip side of running a lighter machine.
This model also has one of the lower averages in the roundup at 4.2, with 9 percent one-star reviews. The spool system is auto-feed only, without the wider line options of competing heads, so it is not the tool for very thick growth.
10. SKIL PWR CORE 40 14 Inch Brushless Kit: Best for Tall Grass and Briars
SKIL PWR CORE 40 14-Inch Brushless 40V Lightweight String Trimmer Kit with Twist Load Including 2.5Ah Battery and Auto PWR JUMP Charger – LT4818-10
14 inch swath
Digital brushless motor
2.5Ah battery
Auto PWR JUMP charger
5-year limited warranty
Pros
- Brushless motor with gas-comparable cutting power
- Cuts tall thick grass and briers
- Twist Load head needs no tools to reload
- Auto PWR JUMP charger tops up during breaks
- 5-year limited warranty is the longest here
Cons
- 12.4 lb listed weight causes fatigue without a strap
- Charger fan is audible while charging
- Bump feed instead of auto feed
- One owner reported early battery failure
The SKIL is the one we would test on the worst ground in the roundup. Owners consistently describe it as a gas replacement for edging and weed eating on half-acre to one-acre lots, and the digital brushless motor delivers the throttle response you would expect from a much heavier machine.
It punches through tall, thick grass and brier patches where lighter trimmers bog down. The 14 inch swath gives it enough coverage to make sense on a bigger lot, and the PWR CORE 40 cells are wrapped in cooling material for longer run time and extended battery life.
The Twist Load head is refreshingly simple. You insert the line and twist the spool to load it, no tools and no winding by hand, which solves the frustration that comes with pre-wrapped spools in some designs.
What the 5-year warranty actually tells you
Warranty length is a reasonable proxy for how a manufacturer expects its tool to be treated. A 5-year limited warranty alongside weather-resistant construction suggests a tool built for regular outdoor work rather than occasional use.
The Auto PWR JUMP charger is also practical. It tops the pack off during breaks in the job, so a mid-session pause becomes a top-up instead of a restart. The trade-off is that its cooling fan is audible while it runs.
Where it falls short
At 12.4 pounds listed weight, this is a heavy machine, and owners note arm fatigue without a shoulder strap. Plan on using one.
The head uses dual-line bump feed rather than an automatic system, so advancing line means tapping the head on a flat surface. The 2.5Ah pack is also the smallest here, which shortens sessions on thick growth, and one owner reported a battery failure after roughly seven months of seasonal use. With the smallest review base in the roundup at about 620, there is less long-term owner history behind this tool than behind the others.
How to Choose a Battery String Trimmer for Your Yard
Voltage is the first number buyers look at and the least useful number on its own. Amp-hours, weight, and swath decide whether a tool works for your property. Here is how the tiers actually stack up.
20V tools such as the WORX WG163 and BLACK+DECKER LST300 are built for maintenance on yards up to about a quarter acre: lawn grass, clover, flower bed edges, and light fence-line work. They are also the lightest options, which makes them the right call for older users or anyone who wants minimal fatigue. Their limit is consistent, and it is woody and thick-stalk growth.
40V tools such as the BLACK+DECKER LST136, the Greenworks 40V 12 inch, the WORX WG183, the SKIL kit, and the RYOBI handle everything a 20V tool does plus taller grass and heavier weed patches. This is the sensible default tier for a half-acre property, and it is where most of the mid-range buying happens.
56V and 60V tools such as the EGO 16 inch and 15 inch models are for large lots, brambles, neglected fence lines, and anyone replacing a gas trimmer and refusing to compromise. They cost more, weigh more, and demand more battery investment than the entry tiers.
Amp-hours decide runtime, not power. A 4.0Ah pack runs roughly twice as long as a 2.0Ah pack of the same voltage. Two 2.0Ah packs in your garage beat one 4.0Ah pack if you can swap while you work, which is why the WORX models that include two batteries rank so well with owners.
Cutting swath is a time multiplier. A 16 inch head covers a third more ground per pass than a 12 inch head. On a lot where you trim weekly, that difference compounds into minutes saved every single time.
Line gauge matters more than most buyers expect. 0.065 inch line is standard for grass and light weeds. 0.080 inch handles mixed growth. 0.095 inch, used by the EGO 15 inch model, is for vines, brambles, and dense stalk weeds. Running thin line on hard vegetation means more breaks and more reloading.
Feed systems determine daily enjoyment. Manual spools require wrapping line by hand and are the most commonly complained about system in this category. Bump heads advance line by tapping the head on the ground. Push-button and automatic systems, including the WORX Command Feed, the BLACK+DECKER Automatic Feed Spool, the Greenworks auto feed, and the EGO Line IQ and PowerLoad, advance line on demand. Setup confusion is a real issue with automatic heads, as r/egopowerplus owners working out the PowerLoad process show, so read the instructions once before you start.
Weight is a long-session issue, not a lifting issue. Anyone can lift a 13 pound trimmer off the bench. The difference shows up at minute ten, and it is the reason the lightest tools here keep getting recommended for older users and long trimming days.
Check the battery platform before the tool. If you already own batteries from a brand, buying into that ecosystem with a bare tool can cost far less than a full kit. If you are starting from zero, look at what else the platform covers, whether leaf blowers, mowers, and hedge trimmers share the same pack, and what a second battery costs. Lock-in anxiety is a real purchase stopper for owners who want several battery tools.
That platform-first rule is not unique to outdoor power equipment. Our battery-powered LED light picks follow the same logic, because the second pack matters far more than any single unit’s headline number.
Over winter, store batteries charged and dry. Lithium-ion packs left empty or in a freezing shed lose capacity. Charge them fully at the end of the season, keep them off concrete, and expect three to five years of service life before capacity loss becomes obvious in your sessions.
Gas is still the honest answer for some properties. If you are clearing three-foot weeds across an acre, working brambles thick enough to stall a line head, or running sessions longer than an hour, a gas trimmer remains the better tool. Cordless wins on convenience, noise, and maintenance, not on unlimited cutting time.
Wear eye protection, closed toe shoes, and hearing protection where the neighborhood requires it, and keep the debris guard in place around beds and shrubs. A trimmer line spinning at high speed throws small stones and plant fragments hard enough to injure, and that risk does not change because the tool is battery powered.
Frequently Asked Questions
Are gas or electric string trimmers better?
For most homeowners a battery powered string trimmer is better, because it starts instantly, needs no fuel mixing, has no pull cord, and runs quietly enough for early mornings. Gas trimmers still win on very large properties, very thick stalk growth, and sessions longer than about an hour.
What is the best cordless lightweight string trimmer?
The WORX WG163 at 5.5 pounds is the lightest option that still trims and edges, with two batteries included. The BLACK+DECKER LST300 at 5.7 pounds is close behind, and the WORX WG183 at 6.4 pounds is the lightest 40V model if you need more power for tall growth.
How long does a battery string trimmer battery last?
Most lithium-ion trimmer batteries deliver three to five years of useful service before capacity loss shows up in shorter sessions. Storing packs fully charged, dry, and away from freezing temperatures extends that life, and keeping a second pack lets you keep working while one charges.
How do I change trimmer line on a cordless trimmer?
Most heads refill easily. Push-button and automatic systems advance line by pressing a button. Twist Load and bump-feed heads ask you to thread line through the spool and either twist or tap the head. Always follow the instructions for your head, since spool designs differ.
Is 20V enough for a string trimmer?
Yes for maintenance work on yards up to about a quarter acre. A 20V tool handles lawn grass, clover, and light fence-line weeds well. Step up to 40V or higher if you face tall grass, thick stalk weeds, brambles, or a lot larger than a quarter acre.
What size yard is a cordless string trimmer good for?
Cordless trimmers work well on suburban lots up to about half an acre with a single battery charge on models rated for 45 to 60 minutes. On larger properties you will want a second pack, a wider cutting swath, or a higher voltage tool.
Who makes Craftsman string trimmers?
Craftsman string trimmers are made by Stanley Black and Decker, the same company behind BLACK+DECKER and DEWALT tools, and are sold through the Craftsman brand for home use. Homeowners who already own Craftsman batteries can check whether a matching cordless trimmer fits their existing platform.
Do I need a separate lawn edger if I have a string trimmer?
No. Most cordless trimmers in this roundup convert to an edger by tilting or adjusting the cutting head, adding a guide wheel or support wheels for a straight cut along driveways and sidewalks. A dedicated edger is useful only if you edge frequently and want a wider, more precise cut.
Final Word on the Best Battery Powered String Trimmers for Homeowners
The WORX WG163 remains our pick for the best battery powered string trimmers for homeowners in 2026 because it does the two jobs most people actually have, weighs 5.5 pounds, and includes two batteries so one charge never ends your session.
For a small lot, add the BLACK+DECKER LST300 for simpler controls and a wall-mounted charging base. For a half acre or more with tall grass, the BLACK+DECKER LST136 gives you 40V power at a manageable 7.8 pounds. For weeds, vines, and larger acreage, the EGO 16 inch and 15 inch models handle the heaviest work without hand-wrapping line.
Whichever you choose, buy the battery platform first. A trimmer you enjoy using beats a more powerful tool you set aside in the shed.
