5 Best Lightweight Cordless String Trimmers for Easy Yard Work

Looking for the best lightweight cordless string trimmer that will not leave your arms and shoulders tired after routine lawn care? The ideal lightweight trimmer should balance low tool weight, comfortable ergonomics, battery runtime, cutting swath, line feed, and edging capability without sacrificing enough power to handle normal grass and weeds.

My top pick is the WORX WG154 20V PowerShare 10-Inch Cordless String Trimmer & Edger. At only about 4.2 pounds with its battery installed, it is exceptionally easy to carry, while the 10-inch cutting head, automatic line feed, flower guard, and quick trimmer-to-edger conversion make it an excellent match for small residential yards.

For minimum weight and a larger cordless-tool ecosystem, the RYOBI ONE+ 18V 10-Inch Cordless String Trimmer/Edger PCLST01B is another strong option. RYOBI specifically designed it as an ultra-light trimmer for small yards, with an adjustable 8- to 10-inch cut swath, automatic line feed, edging conversion, and more than 35 minutes of claimed runtime with a 2Ah battery.

If you want a simple budget-friendly trimmer that remains easy to control, the BLACK+DECKER LST201 20V MAX 10-Inch String Trimmer/Edger weighs about 4.5 pounds and combines an adjustable handle, adjustable height, automatic line feed, and easy edging conversion.

5 Best Lightweight Cordless String Trimmers

What Makes a Cordless String Trimmer Truly Lightweight?

A string trimmer’s listed weight is only part of the story.

A machine can have a respectable number on the specification sheet and still feel tiring if most of that mass sits behind your rear hand or out near the cutting head.

For that reason, I looked at several factors:

overall weight, battery size, shaft balance, auxiliary-handle adjustment, cutting-head size, shaft length, edging conversion, line-feed system, and typical residential cutting performance.

The battery deserves special attention.

Large 4Ah, 5Ah, and 6Ah lithium-ion packs provide longer runtime, but they can add noticeable weight to the back of a small trimmer. A lightweight machine paired with a compact 1.5Ah or 2Ah battery may actually feel much more comfortable for a homeowner who only trims for 10 to 20 minutes.

Cutting width also matters.

A 10-inch head helps keep weight down and improves maneuverability. A 12- or 13-inch cutting swath requires fewer passes but generally comes with a larger guard, longer line, and somewhat more powerful motor.

The best choice therefore depends on whether your priority is minimum fatigue or faster cutting.

5 Best Lightweight Cordless String Trimmers

1. WORX WG154 20V PowerShare 10-Inch Cordless String Trimmer & Edger- Best Overall

The WORX WG154 is one of the easiest full-size cordless lawn trimmers to handle if weight is your main concern.

WORX lists the complete trimmer at approximately 4.2 pounds with the battery, which is impressively low for a machine that can perform both trimming and edging duties.

That low weight is the primary reason it ranks first.

10-Inch Cutting Width Keeps It Nimble

The WG154 uses a 10-inch cutting diameter.

That is narrow compared with 15- or 16-inch professional-style trimmers, but it works extremely well on smaller lawns.

A compact head is easier to guide around:

trees, fence posts, flower beds, patios, raised beds, mailboxes, sheds, and tight lawn corners.

You sacrifice some productivity on long fence lines, but the trimmer feels significantly easier to control.

For the homeowner searching specifically for lightweight equipment, that trade makes sense.

Only 4.2 Pounds With Battery

Many manufacturers quote bare-tool weight, which can make comparisons misleading.

WORX specifically states that this model is approximately 4.2 pounds with its battery installed.

That makes the WG154 particularly appealing for users who find larger cordless machines uncomfortable.

Lower weight can reduce fatigue in the:

forearms, shoulders, wrists, upper back, and lower back.

It also makes it easier to rotate the tool into edging position.

Automatic Line Feed

The trimmer uses an automatic single-line feed system.

There is no need to repeatedly strike the head against the ground as you would with a conventional bump-feed trimmer.

For routine residential trimming, automatic feed is convenient because you can concentrate on maintaining cutting height and working around landscaping rather than monitoring line length.

The trimmer uses 0.065-inch line, which is appropriate for lawn grass and light weeds.

Quick Trimmer-to-Edger Conversion

The cutting head rotates so the WG154 can function as a cordless lawn edger.

That makes it useful along:

Sidewalks.

Driveways.

Curbs.

Patio borders.

Garden edges.

A dedicated steel-blade edger will make a deeper trench, but the rotating string head is more than adequate for routine edge maintenance.

Flower Guard

A folding spacer guard helps maintain distance between the spinning line and desirable plants.

This is particularly useful if your yard includes decorative landscaping.

Trimmer line can damage tree bark and tender stems surprisingly quickly, so maintaining physical separation is better than relying solely on visual judgment.

PowerShare Battery Compatibility

The WG154 operates on the 20V PowerShare battery platform.

WORX states that the platform extends across a large collection of compatible equipment.

That can improve long-term value if you eventually add compatible blowers, hedge trimmers, drills, or other tools.

Where It Falls Short

The 10-inch cutting swath means more passes on larger properties.

Its 0.065-inch line is also designed for light residential vegetation, not thick brush.

If your yard regularly contains heavy St. Augustine, tall field grass, or mature weeds, the SKIL later in this guide provides more cutting capacity.

Who Should Buy It?

Choose the WORX WG154 if your priorities are:

minimum carrying weight, easy maneuverability, simple edging, and small-yard maintenance.

For routine trimming around an ordinary residential property, it gives up very little while saving a meaningful amount of weight.

2. RYOBI ONE+ 18V 10-Inch Cordless String Trimmer/Edger PCLST01B- Best Ultra-Light Small-Yard Pick

The RYOBI PCLST01B was specifically designed around lightweight trimming.

RYOBI describes it as its lightest-weight string trimmer, intended primarily for small-yard use. It provides an adjustable 8- to 10-inch cutting swath, automatic line feed, and a shaft that twists into edging position.

Designed Around Low Weight

RYOBI lists the trimmer at roughly 4.28 pounds in its current specifications.

That places it firmly in ultra-light territory.

This kind of machine is ideal for people whose lawn mower already handles 95% of the yard and who only need a trimmer for small areas the mower cannot reach.

You are not carrying unnecessary motor capacity or an oversized cutting head for a 10-minute job.

Adjustable 8- to 10-Inch Swath

The adjustable cutting width is clever.

Use the 10-inch setting when you want to cover more grass per pass.

Switch toward the 8-inch setting when maximum runtime or precision is more important.

RYOBI specifically notes that the smaller swath can help extend runtime while the larger configuration improves productivity.

More Than 35 Minutes of Claimed Runtime

RYOBI rates the machine for more than 35 minutes of runtime with a 2Ah ONE+ battery.

That is substantial for a trimmer designed around compact lawns.

If your normal post-mowing trimming session only lasts 10 to 15 minutes, the battery should provide plenty of useful reserve under suitable conditions.

Real runtime varies with grass density, line length, temperature, and technique.

Auto-Feed Head

The PCLST01B uses 0.065-inch line with an automatic-feed head.

Line advances as part of normal operation rather than requiring a traditional bump-feed technique.

This reinforces its homeowner-friendly design.

Twist-to-Edge Shaft

Rotating the shaft converts it from horizontal trimming to vertical edging.

That lets one lightweight tool maintain both grass around obstacles and neat borders along paved areas.

ONE+ Battery Ecosystem

The RYOBI 18V ONE+ platform is one of the tool’s strongest advantages.

RYOBI states that the system now covers more than 300 compatible products.

If you already use ONE+ drills, saws, blowers, lights, or other equipment, buying another compatible lawn tool can be more economical than starting a separate battery platform.

Where It Falls Short

This is not a heavy weed trimmer.

The narrow head and thin line are ideal for maintained grass but less suited to neglected areas.

The lightweight construction also means the machine is optimized around convenience rather than maximum shaft rigidity or commercial durability.

Who Should Buy It?

Choose the RYOBI if you have a small yard, short trimming sessions, and an existing ONE+ battery collection.

It is also one of the first models I would consider for anyone specifically trying to reduce arm and shoulder fatigue.

3. BLACK+DECKER LST201 20V MAX 10-Inch String Trimmer/Edger- Best Budget Lightweight Pick

The BLACK+DECKER LST201 follows the same lightweight philosophy but adds particularly useful adjustment for the operator.

BLACK+DECKER lists the machine at approximately 4.5 pounds, with an adjustable handle, adjustable height, 10-inch cutting width, automatic line feed, and 20V MAX battery.

4.5-Pound Design

At about 4.5 pounds, the LST201 remains easy to carry through an entire small yard.

More importantly, the adjustable height lets you tailor the working position instead of adapting your body to a fixed-length tool.

That is valuable for shorter and taller users alike.

A trimmer that is too short encourages excessive bending.

One that is too long can force your arms outward and increase shoulder fatigue.

AFS Automatic Feed Spool

BLACK+DECKER uses its AFS Automatic Feed Spool.

The system advances trimmer line without requiring the head to be bumped against the lawn.

For casual homeowners, this reduces the learning curve.

Converts to an Edger

Rotating the head changes the LST201 from a conventional grass trimmer into an edging tool.

It works well for maintaining established edges around concrete and garden borders.

20V MAX Battery

The common kit includes a 1.5Ah lithium-ion battery and charger.

A small battery is actually beneficial from a weight perspective.

While a larger 4Ah pack would provide more runtime, it would also increase rear-end weight.

For a lightweight trimmer used on a small lawn, the compact pack is appropriate.

10-Inch Head

Like the WORX and RYOBI, the BLACK+DECKER uses a compact 10-inch cutting swath.

That favors control and maneuverability rather than raw productivity.

The machine is especially comfortable around flower beds and fenced yards where a big 15-inch cutting circle can become awkward.

Where It Falls Short

The compact battery and light-duty cutting head limit performance in heavy vegetation.

This is not the model for cleaning an overgrown drainage ditch or cutting waist-high weeds.

It is designed for grass trimming and light weed control.

Who Should Buy It?

Choose the LST201 if you want an inexpensive, lightweight cordless weed eater with automatic line feed and adjustable ergonomics.

It is especially practical for townhomes, small suburban yards, and light weekly lawn maintenance.

4. Greenworks 24V 12-Inch Cordless String Trimmer/Edger ST24B217- Best Lightweight Pick With a Wider Cut

The Greenworks ST24B217 increases cutting width without moving into genuinely heavy trimmer territory.

Current specifications list a 12-inch cutting width, 24V battery system, and roughly 5.18-pound machine weight for the Gen 2 configuration.

That makes it a good middle ground between ultra-light 10-inch models and larger performance trimmers.

12-Inch Cutting Width

A 12-inch head covers roughly 20% more width per pass than a 10-inch head before accounting for overlap.

Across a long fence line, that difference becomes noticeable.

The Greenworks therefore makes sense for someone who wants a lightweight machine but has enough property that a tiny cutting head would feel slow.

Around Five Pounds

At roughly 5.18 pounds, the Greenworks remains relatively easy to maneuver.

The weight increase over a 4.2-pound machine buys you a wider cutting circle and somewhat more substantial platform.

For many users, this is the sweet spot.

24V Power

The 24V battery architecture provides enough capability for ordinary residential trimming while remaining smaller than Greenworks’ higher-voltage outdoor systems.

This model is best paired with maintained turf rather than heavy overgrowth.

Good Choice Around Landscaping

The 12-inch design remains compact enough to navigate around trees and garden beds.

You get more productivity without jumping immediately to a large straight-shaft machine.

Battery Platform

The Greenworks 24V platform extends to numerous compatible lawn and power tools.

This can be especially useful if you prefer using lighter batteries across several pieces of equipment.

Where It Falls Short

The Greenworks is not as feather-light as the first three picks.

If minimum weight is the only criterion, WORX, RYOBI, or BLACK+DECKER makes more sense.

Its advantage is providing a bit more cutting width while remaining manageable.

Who Should Buy It?

Choose the Greenworks if you want a light cordless trimmer with a more productive 12-inch cutting swath.

It is a particularly good fit for small-to-medium lawns with longer fence lines and borders.

5. SKIL PWR CORE 20 LT4823B-10 13-Inch Brushless String Trimmer- Best Lightweight Power

The SKIL LT4823B-10 stretches the definition of lightweight compared with the tiny 10-inch models above, but it earns a place because it provides significantly stronger cutting hardware without becoming a bulky high-voltage trimmer.

SKIL lists a 13-inch cutting swath, digital brushless motor, dual 0.080-inch line, two speed settings, variable-speed trigger, folding shaft, and a tool weight of 6.2 pounds or less.

Brushless Motor

The digital brushless motor is the biggest reason to choose SKIL.

Brushless technology generally provides better efficiency and power management than a basic brushed motor.

For someone who wants low fatigue but occasionally encounters thicker grass, this extra performance can be valuable.

13-Inch Cutting Swath

The 13-inch head covers considerably more grass per sweep than the 10-inch machines.

This reduces the number of passes required along long fence lines.

Independent testing described the SKIL as well balanced and light enough for small-property owners while still delivering useful weed-cutting performance.

Dual 0.080-Inch Line

The SKIL uses dual 0.080-inch trimmer line rather than the single 0.065-inch line common on ultra-light residential tools.

That gives it a major advantage against:

coarse grass, taller weeds, thicker lawn edges, and denser vegetation.

It is still not a brush cutter, but it gives you more headroom.

Two Speeds Plus Variable Trigger

Low speed reaches approximately 5,000 RPM, while high reaches around 6,000 RPM.

The variable-speed trigger lets you further control output.

Use less power around delicate landscaping and increase speed when vegetation becomes heavier.

This helps balance performance and runtime.

Twist Load Head

SKIL’s Twist Load system simplifies loading fresh string.

Feed the line through the head, center the ends, and twist the head to wind the line onto the spool.

This avoids the tedious hand-winding required by older spool designs.

Folding Shaft

The shaft folds for easier storage.

This is useful if you have limited garage or shed space or occasionally transport the trimmer in a vehicle.

Where It Falls Short

SKIL is noticeably heavier than the top three.

A larger 4Ah battery also adds more mass than the small packs used by ultra-light models.

If your lawn only requires five minutes of trimming, the additional performance may not justify that weight.

Who Should Buy It?

Choose the SKIL if you want a relatively lightweight cordless string trimmer that can still handle thicker grass with a brushless motor and 0.080-inch dual line.

It is the performance-oriented pick in this group.

Lightweight Cordless String Trimmer Comparison

Product	Weight	Cut Swath	Line	Key Feature	Best For
WORX WG154	~4.2 lb with battery	10 in.	0.065 in.	Auto feed, 2-in-1	Best overall
RYOBI PCLST01B	~4.3 lb	8–10 in.	0.065 in.	Adjustable swath	Minimum fatigue
BLACK+DECKER LST201	~4.5 lb	10 in.	0.065 in.	Adjustable height	Budget use
Greenworks ST24B217	~5.2 lb	12 in.	Light-duty line	Wider head	Faster residential trimming
SKIL LT4823B-10	≤6.2 lb tool spec	13 in.	Dual 0.080 in.	Brushless motor	More cutting power

How Light Should a Cordless String Trimmer Be?

For genuinely lightweight residential use, I consider approximately 4 to 7 pounds a useful target.

Below five pounds feels exceptionally easy to maneuver.

Between five and seven pounds can still be comfortable while allowing a larger battery, wider cutting head, or stronger motor.

Once machines approach 10 pounds or more, balance and shoulder support become much more important.

Weight tolerance is individual.

A person trimming for five minutes may happily use a heavier tool.

Someone maintaining several hundred feet of fencing may strongly prefer saving even two pounds.

Why Balance Matters as Much as Weight

Imagine two trimmers that both weigh six pounds.

One places three pounds near the cutting head and three pounds near your rear hand.

The other concentrates most of its mass at the far end of the shaft.

The second tool can feel much heavier because your arms must resist greater leverage.

Good weight distribution reduces that effect.

An adjustable front handle also helps because you can reposition your support hand until the trimmer feels more neutral.

This is one reason ergonomic design deserves as much consideration as the scale weight.

Is a Lightweight String Trimmer Powerful Enough?

Yes, for routine residential lawn care.

A lightweight battery trimmer can easily handle:

lawn grass, fence lines, sidewalk edges, weeds around trees, landscaping borders, and common soft-stem weeds.

The limitations appear when vegetation becomes tall, wet, fibrous, or woody.

A tiny 10-inch trimmer with 0.065-inch line is not the ideal machine for clearing an abandoned field.

For that work, move toward:

A brushless motor.

0.080- or 0.095-inch line.

A 13- to 16-inch swath.

A larger battery.

Or an attachment-capable power head.

10-Inch vs. 12-Inch vs. 13-Inch Trimmer

Cutting width changes both productivity and handling.

10-Inch

A 10-inch string trimmer is extremely maneuverable.

It is best for small yards and landscaping-heavy areas.

WORX, RYOBI, and BLACK+DECKER fit this profile.

12-Inch

Twelve inches provides noticeably better productivity while remaining compact.

Greenworks provides this useful middle ground.

13-Inch

A 13-inch machine like SKIL begins to feel closer to a traditional residential straight-shaft trimmer.

It requires fewer passes and supports heavier line, but weight increases.

Does Battery Size Affect Trimmer Weight?

Yes, significantly.

A compact 1.5Ah or 2Ah battery is much lighter than a large 5Ah or 6Ah pack.

This creates an important buying decision.

If your yard requires only 15 minutes of trimming, using the smallest practical battery can make the machine much more comfortable.

You do not necessarily need the maximum-capacity battery available for the platform.

Larger batteries make more sense when runtime matters more than minimizing weight.

18V vs. 20V vs. 24V for Lightweight Trimmers

Do not buy based on voltage alone.

Many 20V MAX systems are approximately 18V nominal, while different brands use different battery architectures and labeling.

For lightweight residential tools, all three voltage classes can work well.

Instead compare:

weight, watt-hour capacity, cutting swath, line size, motor type, and runtime.

The RYOBI 18V and WORX 20V models are extremely lightweight.

Greenworks 24V provides a slightly wider cutting platform.

SKIL 20V uses brushless technology and heavier dual line for more performance.

0.065 vs. 0.080 Trimmer Line

Line diameter strongly influences what vegetation a trimmer handles comfortably.

0.065-Inch Line

Best for:

Normal lawn grass.

Light weeds.

Edging.

Small residential yards.

It also helps keep the rotating mass and motor demand lower.

WORX, RYOBI, and BLACK+DECKER use this lighter-duty class.

0.080-Inch Line

Better for:

Coarser grass.

Taller weeds.

Long fence lines.

More demanding residential work.

SKIL’s 0.080-inch dual-line head provides noticeably more capability.

Automatic Feed vs. Bump Feed

Ultra-light trimmers frequently use automatic feed because it is simple for casual homeowners.

The mechanism advances additional line without intentionally tapping the head against the ground.

WORX, RYOBI, and BLACK+DECKER all emphasize easy line advancement.

A bump-feed head gives the user more control over exactly when line advances.

SKIL uses bump feed combined with its Twist Load reloading system.

Neither approach is universally superior.

Auto feed favors simplicity.

Bump feed favors operator control.

Are Lightweight Trimmers Good for Edging?

Yes.

In fact, lower weight can make edging easier because you have to rotate and guide the cutting head vertically.

WORX, RYOBI, and BLACK+DECKER all convert easily between trimming and edging modes.

For routine sidewalk maintenance, that is usually enough.

A dedicated blade edger is still better for establishing a brand-new deep edge between lawn and pavement.

Best Lightweight Cordless Trimmer for Seniors

A tool for an older user should not be chosen based on age alone.

Physical comfort varies significantly from person to person.

However, useful features generally include:

low total weight, balanced shaft, adjustable handle, easy trigger, automatic line feed, simple battery installation, and minimal vibration.

The WORX WG154, RYOBI PCLST01B, and BLACK+DECKER LST201 are particularly appealing when reducing lifting effort is the main goal.

Best Lightweight Cordless Trimmer for Women

The same principle applies: there is no separate technical requirement based on gender.

Choose according to the operator’s height, grip comfort, strength, trimming duration, and yard size.

An adjustable shaft and auxiliary handle can be particularly useful for smaller users because they prevent the tool from forcing an awkward working posture.

The lightest machines in this guide are easy to reposition regardless of who operates them.

Best Lightweight Cordless Trimmer for a Small Yard

For a small yard, I would prioritize comfort over maximum power.

If mowing takes 20 minutes and trimming takes another eight, there is little benefit in carrying a large 15-pound professional machine.

A 10-inch cordless trimmer is enough to maintain grass around obstacles and finish the lawn neatly.

WORX and RYOBI are especially well matched to this situation.

How Much Runtime Do You Need?

Time your normal trimming session.

That is far more useful than obsessing over maximum advertised runtime.

If your normal job takes 12 minutes, a battery capable of 25 to 35 minutes already provides substantial reserve.

RYOBI claims more than 35 minutes with a 2Ah battery on the PCLST01B under appropriate conditions.

A larger property may benefit from either a second small battery or a larger-capacity pack.

Should You Choose Brushless?

A brushless string trimmer generally provides better efficiency, stronger power management, and no carbon brushes to wear inside the motor.

But brushless technology often costs more.

For a homeowner trimming a tiny lawn, the advantage may not justify additional weight or expense.

For thicker vegetation, it becomes more valuable.

That is why SKIL serves a different buyer than the ultra-light WORX and RYOBI models.

How to Reduce Fatigue While String Trimming

Set the shaft so you can stand relatively upright.

Move the auxiliary handle until both arms remain relaxed.

Do not grip the trimmer harder than necessary.

Use smooth side-to-side sweeps rather than aggressive chopping movements.

Allow the tip of the trimmer line to perform most of the cutting.

Keep the cutting head at a consistent height.

Take advantage of lower motor speed when available.

And use an appropriately sized battery instead of automatically attaching the largest pack in the platform.

These small changes can make a six-pound trimmer feel dramatically easier over a long session.

Final Verdict

The WORX WG154 is my overall choice for the best lightweight cordless string trimmer. At roughly 4.2 pounds with its battery, it provides the comfort advantage lightweight-tool buyers want while retaining a useful 10-inch cutting head, automatic feed, plant guard, and edging capability.

The RYOBI PCLST01B is an excellent alternative for extremely light small-yard work. Its adjustable 8- to 10-inch cutting swath, automatic feed, edging conversion, and compact ONE+ battery system make it particularly comfortable during short maintenance sessions.

The BLACK+DECKER LST201 is the budget-focused choice, combining approximately 4.5-pound weight with adjustable ergonomics and simple automatic line advancement.

Choose the Greenworks ST24B217 when you want a lightweight machine but prefer a wider 12-inch cutting path that can finish longer borders faster.

The SKIL LT4823B-10 is the performance-oriented lightweight option. It weighs more than the tiny 10-inch machines, but its brushless motor, 13-inch swath, dual 0.080-inch line, variable-speed trigger, and two-speed control give it significantly more capability in thicker grass.

For most homeowners, the right lightweight trimmer is not the absolute lightest number on a scale. The better choice balances tool weight, battery weight, cutting width, shaft balance, runtime, line diameter, and ergonomic adjustment so you can finish the entire yard comfortably without carrying more machine than you actually need.
