5 Best Battery Powered String Trimmer and Edger Picks

Are you looking for the best battery powered string trimmer and edger to clean up grass around fences, flower beds, sidewalks, and driveway edges without dealing with gasoline or extension cords? The best models combine a useful cutting swath, lithium-ion battery platform, adjustable speed, reliable line feed, comfortable shaft design, and an edging system that can create a clean border without requiring a completely separate tool.

My top overall recommendation is the EGO POWER+ MHC1603 56V Multi-Head String Trimmer and Edger Combo Kit. Unlike basic 2-in-1 trimmers that simply rotate the string head sideways, the EGO includes a 16-inch carbon-fiber string trimmer attachment and a dedicated 8-inch blade edger. Its 56V 4.0Ah ARC Lithium battery, brushless power head, POWERLOAD line system, and attachment ecosystem make it the strongest choice for homeowners who want serious trimming and true edging performance.

For smaller lawns and buyers who prioritize low weight, the WORX WG163 GT 3.0 20V PowerShare 12-Inch String Trimmer and Lawn Edger is one of the easiest tools to live with. It weighs about 5.5 pounds, converts between trimming and wheeled edging, uses a 90-degree pivoting head, and includes two 20V PowerShare batteries. The exact listing has accumulated more than 27,000 customer ratings, giving it one of the largest owner histories in this category.

For value-focused homeowners, the BLACK+DECKER LSTE525 20V MAX 12-Inch String Trimmer and Edger is another proven option. Its two-speed control, PowerDrive transmission, EASYFEED line advancement, wheeled edging conversion, and two included 1.5Ah batteries make it particularly practical for routine residential trimming.

5 Best Battery Powered String Trimmer and Edger

EGO POWER+ MHC1603 56V Multi-Head String Trimmer and Edger Combo Kit- Best Overall

Specification	EGO MHC1603
Battery	56V 4.0Ah ARC Lithium
Trimmer Width	16 inches
Edger	Dedicated 8-in. blade
Motor	Brushless
Line Loading	POWERLOAD
Speed Control	2-speed + variable trigger
Trimmer Runtime	Up to 45 min
Edger Runtime	Up to 75 min on low
Shaft	Carbon fiber
Best For	Medium to large residential yards

The EGO MHC1603 is the standout product here because it gives you a proper trimming attachment and a dedicated blade edger rather than asking one string head to perform both jobs.

The kit includes the PH1420 power head, STA1600 16-inch carbon-fiber string trimmer attachment, EA0820 8-inch carbon-fiber edger attachment, a 56V 4.0Ah ARC Lithium battery, 320W charger, and shoulder strap. EGO rates runtime at up to approximately 45 minutes with the string trimmer and up to 75 minutes with the edger on low.

The dedicated edger is the biggest reason to spend more.

A rotating string trimmer is perfectly adequate for light sidewalk edging, but a steel edging blade with a guide wheel and depth adjustment produces a more consistent groove along concrete.

EGO’s edger can be adjusted to a cutting depth of up to about three inches, giving it enough control for established lawn edges that have begun growing over sidewalks and driveways.

The string trimmer is equally impressive.

Its 16-inch cutting swath is considerably wider than the 12- and 13-inch consumer trimmers elsewhere in this guide, so you cover more grass with every sweep.

The POWERLOAD system is another major advantage.

Instead of manually winding trimmer line around a spool, you feed the line through the head and activate the system to wind it automatically.

Anyone who has spent ten minutes fighting a tangled spool will appreciate how much frustration that removes.

The brushless motor also gives EGO a performance advantage when weeds become denser. Brushless designs generally provide better electrical efficiency, lower internal wear, and more responsive torque control than inexpensive brushed motors.

EGO’s Multi-Head system adds long-term value because the same power head can operate additional compatible attachments, including pole saws, cultivators, hedge trimmers, snow tools, and more. EGO currently lists a broad attachment catalog around the system.

The main trade-off is cost.

This is significantly more expensive than a basic 20V homeowner trimmer.

It also requires physically swapping attachments when transitioning from trimming to edging.

For homeowners who edge regularly and want the cleanest result, however, that inconvenience is worth accepting.

Best for: Medium-to-large lawns, thick grass, frequent edging, EGO battery owners, and buyers wanting a true dedicated edger.

Main limitation: Premium price and heavier multi-head design.

WORX WG163 GT 3.0 20V PowerShare 12-Inch String Trimmer and Lawn Edger- Best Lightweight

Specification	WORX WG163
Battery Platform	20V PowerShare
Batteries	2 included
Cutting Width	12 in.
Weight	Approx. 5.5 lb
Speed	Approx. 7,600 RPM
Edging	Wheeled conversion
Head	90° pivot
Line Feed	Command Feed
Best For	Small lawns

The WORX WG163 GT 3.0 takes the opposite approach.

Instead of maximizing power, WORX focuses on low weight, maneuverability, simple edging conversion, and homeowner-friendly ergonomics.

The WG163 weighs approximately 5.5 pounds, uses a 12-inch cutting diameter, and comes with two lightweight 20V PowerShare lithium-ion batteries. Its head pivots through 90 degrees and converts from string trimming to wheeled edging without requiring another attachment.

This is my favorite model for homeowners who find larger straight-shaft trimmers tiring.

At roughly half the weight of some high-performance battery trimmers, it is easy to maneuver around trees, raised beds, fencing, mailboxes, landscape edging, and other obstacles.

The wheeled edging system is particularly good for beginners.

Rotate the trimmer into edge mode and the small wheels help guide the cutting line along sidewalks and driveways.

That physical support makes it easier to maintain a straight line instead of trying to balance the spinning head in midair.

WORX also includes its Command Feed system.

Pressing the button advances cutting line when needed instead of requiring repeated bumping against the ground.

The adjustable spacer guard is another useful feature when trimming close to flowers or ornamental plants.

The PowerShare ecosystem increases the value if you already own WORX batteries. Compatible batteries can be used across numerous WORX lawn and power tools within the appropriate voltage configuration.

The main limitation is cutting power.

A 12-inch, lightweight 20V machine is optimized for routine grass maintenance—not reclaiming a neglected field full of woody weeds.

If you trim weekly and keep the lawn relatively controlled, that is not a problem.

For dense vegetation, the EGO is in another performance class.

Best for: Small suburban yards, seniors, lightweight trimming, tight landscaping, and frequent sidewalk edging.

Main limitation: Less power and narrower cutting swath than premium models.

BLACK+DECKER LSTE525 20V MAX 12-Inch String Trimmer and Edger- Best Value

The BLACK+DECKER LSTE525 remains one of the most practical cordless trimmer/edger combinations for homeowners who do not need professional-level power.

The kit uses the company’s 20V MAX battery platform, includes two 1.5Ah lithium-ion batteries, and provides a 12-inch cutting swath.

BLACK+DECKER combines two-speed control, PowerDrive transmission, EASYFEED line advancement, and a rotating shaft that converts the trimmer into a wheeled edger.

Specification	BLACK+DECKER LSTE525
Battery	20V MAX
Batteries Included	2 × 1.5Ah
Cutting Width	12 in.
Line Diameter	0.065 in.
Speeds	2
Maximum Speed	About 7,200 RPM
Edging	Wheeled conversion
Line System	EASYFEED
Weight	Approx. 5.3 lb

Two-speed control is particularly useful on a smaller battery platform.

Use the lower setting for routine grass trimming when runtime matters.

Switch to the higher setting when you hit denser patches that require additional cutting speed.

BLACK+DECKER’s PowerDrive transmission is intended to deliver more torque to the cutting line, helping the tool maintain useful performance when grass becomes thicker.

I also like the EASYFEED system.

It allows line advancement with the push of a button instead of forcing you to bump the spool against the ground.

The telescoping and rotating shaft makes switching to edging straightforward.

Once in edge mode, the wheel provides a physical reference against pavement, which makes it easier to establish consistent borders.

The two included batteries are small, but having a second pack is valuable. You can swap batteries rather than stopping completely when the first pack is depleted.

Because the batteries belong to the broader BLACK+DECKER 20V MAX ecosystem, homeowners who already own compatible drills, blowers, hedge trimmers, or other tools may have additional packs available.

The LSTE525 has also accumulated a very large Amazon ownership history, with current marketplace data showing well over 13,000 customer ratings for the exact model.

Its limitation is heavy vegetation.

The 0.065-inch line and 20V architecture are best suited to normal residential grass rather than thick brush.

Best for: Budget-conscious homeowners, small lawns, light-to-medium trimming, and BLACK+DECKER battery users.

Main limitation: Small included batteries and lighter-duty cutting line.

CRAFTSMAN V20 CMCST900D1 13-Inch String Trimmer and Edger Kit- Best 20V All-Rounder

The CRAFTSMAN CMCST900D1 sits between compact 12-inch homeowner trimmers and more expensive high-voltage machines.

It provides a 13-inch cutting swath, 2.0Ah V20 battery, two operating speeds, automatic line advancement, telescoping shaft, and a twist-to-edge design.

CRAFTSMAN lists the complete kit with the battery, charger, spool, auxiliary handle, and guard.

Specification	CRAFTSMAN CMCST900D1
Battery	V20 2.0Ah
Cutting Width	13 in.
Speeds	2
Line Feed	Automatic
Shaft	Telescoping
Edger Conversion	Twist-to-edge
Weight	Approx. 6.3 lb
Rated Runtime	Up to ~25 min
Best For	Small-to-medium lawns

The extra inch of cutting width compared with many 12-inch models makes a noticeable difference over an entire yard.

It does not sound significant on paper, but a wider cutting swath reduces how many passes you make along fence lines and open areas.

CRAFTSMAN also uses two operating modes so you can prioritize either runtime or power.

The telescoping pole helps adapt the machine to different operator heights and makes rotating into edging position easier.

Its automatic line system eliminates the need for manual bump feeding during normal use.

CRAFTSMAN rates runtime at up to approximately 25 minutes with the included battery, although actual performance depends heavily on vegetation density, speed selection, cutting technique, and battery condition.

That runtime is sufficient for many smaller properties but is the main reason I would not choose it for a large lawn unless I already owned spare V20 packs.

The broader CRAFTSMAN V20 ecosystem is an important consideration. If your garage already contains V20 drills, saws, blowers, or other outdoor tools, battery compatibility makes this trimmer much more attractive.

The exact model also has a strong Amazon track record, currently carrying roughly a 4.4-star rating from more than 2,000 reviews.

Best for: Small-to-medium lawns, existing CRAFTSMAN V20 owners, and buyers wanting more cutting width than ultra-light 12-inch tools.

Main limitation: Included 2.0Ah battery limits runtime compared with larger-capacity kits.

Greenworks ST40B05 40V 13-Inch Cordless String Trimmer and Edger Gen 2- Best for Greenworks 40V Owners

The Greenworks ST40B05 is the most attractive choice here for homeowners already invested in the Greenworks 40V battery platform.

It combines a 13-inch cutting path, two-speed operation, auto-feed 0.065-inch line, telescoping aluminum shaft, seven-position pivoting head, and a wheeled edging configuration.

The tool weighs approximately 5.18 pounds without a battery, keeping it relatively manageable despite using a higher-voltage platform.

Specification	Greenworks ST40B05
Battery Platform	40V
Cutting Width	13 in.
Line	0.065 in.
Head Positions	7
Edging	Wheeled 2-in-1
Line Feed	Automatic
Shaft	Telescoping aluminum
Tool Weight	Approx. 5.18 lb
Best For	Existing Greenworks 40V users

The higher-voltage platform gives Greenworks more electrical headroom than typical 20V homeowner trimmers, although motor design and battery discharge capability matter just as much as voltage itself.

Greenworks rates the no-load speed as high as approximately 9,000 RPM, and the seven-position head provides useful flexibility for trimming underneath low obstacles and working on uneven landscaping.

The edger conversion is simple.

Rotate the head into its 90-degree position and use the integrated wheel to guide the cutting line beside concrete.

This is not as precise as the dedicated steel blade on the EGO, but it works well for maintaining already-established sidewalk and driveway edges.

The auto-feed head uses 0.065-inch line, which keeps the machine relatively lightweight and efficient.

For normal lawn grass and small weeds, that diameter is adequate.

For very thick weeds and woody growth, heavier professional-style line would be preferable—but this tool is not really designed as a brush cutter.

One important buying consideration is configuration.

Greenworks sells many products in tool-only and kit versions, so check the exact Amazon listing to confirm whether the battery and charger you need are included before ordering.

For someone who already owns Greenworks 40V batteries from a mower, blower, or other tool, buying a tool-only configuration can be particularly economical.

Best for: Greenworks 40V battery owners, small-to-medium lawns, trimming on slopes, and homeowners who want a lightweight higher-voltage platform.

Main limitation: 0.065-inch line is intended more for grass than heavy brush.

How to Choose the Best Battery Powered String Trimmer and Edger

Choosing a cordless trimmer based only on voltage is one of the easiest ways to buy the wrong tool.

You should evaluate the complete system:

cutting swath, battery capacity, motor type, line diameter, weight, shaft balance, line-feed mechanism, edging design, runtime, and battery ecosystem.

A powerful trimmer that hurts your shoulders after ten minutes is not necessarily better than a smaller tool that comfortably finishes your entire yard.

Dedicated Edger vs. Rotating String Trimmer

This is perhaps the most important distinction in this category.

Most inexpensive trimmer/edger combinations use one string-trimmer head.

You rotate the head 90 degrees and guide the spinning nylon line vertically beside the sidewalk.

This design is:

simple,

lightweight,

inexpensive,

and perfectly adequate for maintaining established edges.

Products such as WORX, BLACK+DECKER, CRAFTSMAN, and Greenworks follow this general approach.

The EGO MHC1603 is different.

Its dedicated 8-inch steel edger blade cuts into soil and turf rather than simply trimming grass with nylon line.

That provides straighter, deeper, and more defined edges.

If you edge once or twice per year, you probably do not need that level of equipment.

If you want a professionally defined border every few weeks, a dedicated blade edger is much better.

Cutting Swath: 12 vs. 13 vs. 16 Inches

Cutting swath determines how wide an area the string clears with each pass.

A 12-inch trimmer is compact and maneuverable.

That width is excellent for:

small lawns,

tight spaces,

flower beds,

and detailed trimming.

Moving to 13 inches gives slightly more productivity without dramatically increasing tool size.

A 16-inch trimmer, such as the EGO, covers substantially more grass and makes more sense for medium-to-large properties.

Wider is not always better.

If most of your trimming happens between closely spaced shrubs and garden borders, a large head can actually be less precise.

20V vs. 40V vs. 56V String Trimmers

Battery voltage tells you about the electrical architecture, but it does not directly tell you how effectively the trimmer cuts.

Actual performance depends on:

motor efficiency, battery current delivery, controller design, gearing, RPM, line diameter, and cutting-head geometry.

A quality 20V trimmer can be excellent for regular lawn grass.

A 40V or 56V platform becomes more attractive when you need:

longer runtime,

larger cutting widths,

thicker line,

stronger torque,

or multiple high-demand lawn tools.

Do not buy 56V solely because the number is larger.

Buy it because your lawn and workload justify the additional size, cost, and battery weight.

Battery Amp-Hours Matter

The amp-hour rating (Ah) is a useful indicator of battery capacity when comparing packs within the same voltage family.

A 4.0Ah battery generally stores approximately twice as much charge as a 2.0Ah battery at the same nominal voltage.

That usually means longer runtime, but it also means more weight.

This is important on handheld tools.

A huge battery that feels perfectly reasonable on a lawn mower can make a string trimmer tiring.

For typical homeowner trimming, I like 2.0Ah to 4.0Ah packs because they provide a useful balance of runtime and handling.

Brushless vs. Brushed Motors

The EGO uses a high-efficiency brushless motor, while budget cordless trimmers may use simpler motor designs.

Brushless technology can provide:

better electrical efficiency,

lower internal wear,

less heat,

and improved power control.

That becomes useful in thicker vegetation where motor load changes rapidly.

For occasional light trimming, a brushed motor can still provide years of adequate service.

For frequent or demanding use, I prefer brushless.

String Diameter

The cutting line is not a minor specification.

Common homeowner trimmers use approximately 0.065-inch line.

This thin line cuts grass efficiently, consumes relatively little power, and works well with lightweight heads.

For tougher vegetation, higher-end trimmers may accept:

0.080-inch,

0.095-inch,

or thicker line.

Heavier line carries more momentum into weeds but requires more motor power.

Do not install thicker line than the manufacturer specifies.

It can overload the head, reduce performance, or create a safety problem.

Automatic Feed vs. Command Feed vs. POWERLOAD

These terms describe different jobs.

Automatic feed advances line as the system determines more cutting line is required.

BLACK+DECKER’s EASYFEED and WORX’s Command Feed give the operator more direct control through a button.

EGO’s POWERLOAD addresses a different annoyance: actually loading new line into the spool.

Feed the line through the head and press the POWERLOAD button to wind it.

If replacing trimmer line is one of your least favorite yard chores, that feature is genuinely useful.

Weight and Balance Matter More Than People Expect

You typically hold a string trimmer away from your body while swinging it from side to side.

A difference of two pounds can therefore feel much greater after 30 minutes than it does when simply lifting tools in a store.

The WORX and BLACK+DECKER designs are particularly attractive for people who prioritize low weight.

Higher-power tools such as EGO provide much greater capability but are physically more substantial.

A shoulder strap can reduce arm fatigue on heavier multi-head systems.

Telescoping Shafts

A telescoping shaft lets you adjust tool length for your height.

This matters both for comfort and cutting accuracy.

If the shaft is too short, you bend forward continuously.

If it is too long, controlling the cutting head becomes awkward.

WORX, BLACK+DECKER, CRAFTSMAN, and Greenworks all emphasize adjustable ergonomics in their homeowner-focused designs.

Correct shaft length allows you to stand relatively upright while keeping the string head parallel to the ground.

Straight Shaft vs. Curved Shaft

Straight shafts provide better reach beneath shrubs and landscape obstacles.

They are also common on higher-performance battery trimmers.

Curved or highly adjustable shafts can feel more comfortable for shorter users.

For edging, what matters most is whether the head or shaft can rotate cleanly into a vertical position.

Battery Ecosystem Should Influence Your Decision

Buying a cordless outdoor tool means buying into a battery platform.

The EGO 56V battery can power numerous EGO outdoor tools.

WORX PowerShare batteries operate across a broad WORX lineup.

BLACK+DECKER has its 20V MAX platform.

CRAFTSMAN uses V20.

Greenworks has several different voltage platforms, including 24V, 40V, 60V, and 80V, so compatibility should be checked carefully.

If you already own two compatible batteries, choosing another tool from that ecosystem can save a substantial amount of money.

How Much Runtime Do You Need?

String trimming usually requires much less total runtime than mowing.

A typical homeowner may mow for 45 minutes but trim for only 10–20 minutes.

That is why lightweight batteries often work well on trimmers.

Consider how much edging you perform as well.

If you have hundreds of feet of sidewalks, driveway borders, retaining walls, and beds, a higher-capacity battery becomes much more useful.

EGO’s official ratings of up to approximately 45 minutes of trimming and 75 minutes of edging with the MHC1603 provide substantial headroom for residential use.

How to Use a String Trimmer as an Edger

For a convertible trimmer, stop the motor before changing positions.

Rotate the shaft or head into the manufacturer’s edging position.

The cutting line should now spin in a vertical plane.

Use the guide wheel where provided.

Move slowly along the boundary between turf and pavement.

Do not bury excessive line into the soil.

You generally want to remove grass that has grown across the concrete edge rather than excavating a deep trench.

For a dedicated blade edger, set the depth conservatively at first.

You can deepen the cut during another pass if necessary.

How Often Should You Edge a Lawn?

There is no universal schedule.

During active spring and summer growth, many lawns benefit from edging every two to four weeks.

Fast-growing turf such as Bermuda may require more frequent maintenance along warm pavement.

If the border is already established, quick maintenance passes take much less time than waiting until several inches of grass have grown across the sidewalk.

Can a String Trimmer Replace a Lawn Edger?

For routine maintenance, yes.

A rotating string trimmer can maintain established lawn borders very effectively.

For creating a new edge through turf and soil, a blade edger is substantially better.

This is why EGO wins overall in this guide.

The dedicated edger attachment can create and maintain a defined groove rather than depending entirely on flexible nylon line.

Frequently Asked Questions

What is the best battery powered string trimmer and edger?

The EGO POWER+ MHC1603 is my best overall choice.

It combines a 16-inch carbon-fiber string trimmer, dedicated 8-inch blade edger, brushless 56V power head, 4.0Ah battery, POWERLOAD line system, and a large attachment ecosystem.

What is the best lightweight cordless trimmer and edger?

The WORX WG163 is my preferred lightweight option.

At roughly 5.5 pounds, it is easy to maneuver and converts into a wheeled edger. The 90-degree pivoting head also helps on slopes and beneath obstacles.

What is the best budget battery string trimmer and edger?

The BLACK+DECKER LSTE525 offers excellent value for a small residential lawn.

It includes two batteries, two speeds, EASYFEED line control, and a wheeled edging conversion while maintaining a relatively low tool weight.

Is 20V enough for a string trimmer?

Yes, 20V is enough for routine residential grass trimming.

Models from WORX, BLACK+DECKER, and CRAFTSMAN demonstrate that a well-designed 20V trimmer can comfortably maintain small and medium suburban yards.

For thick vegetation and wider cutting swaths, higher-voltage equipment offers more headroom.

Is 40V better than 20V for a weed eater?

40V generally provides more performance potential, but it is not automatically necessary.

A small flat yard may be easier to maintain with a lightweight 20V model.

Choose according to vegetation density and runtime requirements rather than voltage alone.

Is a dedicated edger better than a string trimmer?

Yes, when you want deep, highly defined lawn edges.

A blade edger physically cuts turf and soil.

A rotating string trimmer is faster and more convenient for maintaining an edge that already exists.

What string trimmer is easiest to edge with?

Wheeled convertible trimmers such as the WORX WG163 are particularly beginner-friendly.

The wheels support the head and help maintain a straight line beside concrete.

For maximum precision, EGO’s dedicated blade edger is better.

What size string trimmer is best for home use?

A 12- to 13-inch cutting swath is ideal for many small-to-medium residential yards.

It provides enough productivity without becoming difficult to maneuver.

For larger properties, a 15- or 16-inch model saves time.

Is automatic line feed better than bump feed?

It is more convenient for many homeowners, but neither design is universally superior.

Automatic and push-button feed systems eliminate repeated head bumping.

Traditional bump-feed heads remain simple, proven, and popular on heavier-duty trimmers.

How long do cordless string trimmer batteries last?

Per-charge runtime commonly ranges from roughly 20 minutes to well over 45 minutes depending on the battery and workload.

Thicker weeds, high speed, long cutting line, and larger heads increase electrical demand.

Battery capacity gradually declines with age and charge cycles.

Can you edge a driveway with a string trimmer?

Yes. A convertible string trimmer works very well for maintaining driveway edges.

Rotate the cutting head vertically and follow the pavement edge slowly.

Avoid repeatedly striking concrete because it consumes line rapidly.

What line size is best for normal grass?

Around 0.065 to 0.080 inch works well for routine residential grass.

Heavier vegetation may benefit from approximately 0.095-inch line when the specific trimmer is designed to accept it.

Should I buy a trimmer with two batteries?

Two batteries are useful when the included packs have relatively low capacity.

The BLACK+DECKER and WORX kits benefit from having spare batteries available.

If one high-capacity pack already provides enough runtime, a second battery becomes less important.

Are battery string trimmers as good as gas?

Modern premium battery trimmers are powerful enough for most residential properties.

Gas remains attractive for continuous commercial use and extremely heavy vegetation, but cordless tools eliminate fuel mixing, carburetor maintenance, pull starting, exhaust, and much of the routine engine maintenance.

Should I buy a trimmer and edger combo or separate tools?

Buy a combination tool for convenience and separate or interchangeable attachments for maximum edging performance.

A lightweight rotating trimmer is excellent for small lawns.

If crisp edging is a major priority, a system such as the EGO MHC1603 gives you a dedicated blade without requiring a completely separate battery platform.

Which Battery Powered String Trimmer and Edger Should You Buy?

Choose the EGO MHC1603 if you want the strongest overall trimming and edging system. The dedicated 8-inch blade edger, 16-inch trimmer, POWERLOAD system, brushless motor, carbon-fiber shafts, and expandable Multi-Head platform justify the premium for serious residential lawn care.

Choose the WORX WG163 if lightweight handling matters most. Its 5.5-pound design, wheeled edging mode, adjustable head, and PowerShare batteries make routine lawn maintenance unusually easy.

Choose the BLACK+DECKER LSTE525 if you want maximum value from an established homeowner platform. Two batteries, EASYFEED, two speeds, and wheeled edging give it a strong feature set for the money.

Choose the CRAFTSMAN CMCST900D1 if you already own V20 batteries or want a slightly wider 13-inch cutting path without moving into a large high-voltage machine.

Choose the Greenworks ST40B05 if you are invested in the Greenworks 40V ecosystem and want a lightweight trimmer with a pivoting head and wheeled edging conversion.

Final Verdict

The EGO POWER+ MHC1603 is the best battery powered string trimmer and edger for buyers who want one cordless system capable of delivering both powerful trimming and genuinely precise edging.

Its 56V ARC Lithium battery, brushless motor, 16-inch cutting swath, carbon-fiber construction, POWERLOAD line loading, and dedicated 8-inch steel edger attachment place it in a different performance category from typical rotating-head homeowner trimmers.

The WORX WG163 is the better choice when comfort and low weight outweigh maximum cutting power, while the BLACK+DECKER LSTE525 remains one of the most compelling budget options.

CRAFTSMAN provides an excellent middle ground with its 13-inch V20 design, and Greenworks makes particular sense for homeowners who already have compatible 40V batteries.

For the best buying decision, match the tool to your actual property. Consider cutting width, line diameter, battery amp-hours, voltage, motor design, tool weight, shaft adjustment, line-feed system, edging mechanism, and—most importantly—the cordless battery platform you plan to use across the rest of your lawn equipment.
