  8. Frequently asked questions about 20V string trimmers

The best 20V string trimmer for most small to medium yards is the WORX WG163, a 2-in-1 tool with a tilting head, edging wheels, push-button line feed and 2 included batteries. For a wider cut, consider a CRAFTSMAN 13 in model; for a folding tool, look at the DeWalt DCST922B.

A 20V label alone does not tell you how well a trimmer fits your yard. Swath, weight, battery inclusion, line feed and the way you plan to edge all affect the choice.

If you are comparing battery classes, our 40V vs 20V trimmer guide explains what to weigh before choosing a platform. For a wider set of cordless options, see our best cordless weed eaters for home lawns.

How we chose the best 20V string trimmers

The best 20V string trimmer depends on the work you need it to do, so we compared cutting width, line feed, included batteries, edging features and storage needs. We also checked whether each option is a full kit or a bare tool.

Our score weighs specs, features and buyer feedback against what you’re shopping for.

The list puts lighter, versatile kits near the top, then includes wider-cutting, multi-tool and bare-tool choices for different yards. A battery included in a kit can simplify setup, while a bare tool may suit you if you already own compatible batteries.

WORX WG163 20V 2-in-1 Trimmer and Edger: Best for easy edging

WORX WG163 20V 2-in-1 Trimmer and Edger, 20V string trimmers
9.1/10Our score
  • 12 in cutting diameter
  • Tilting head and rubberized edging wheels
  • 2 batteries and charger included
  • Push-button line feed

A light trimmer that switches to edging mode and comes with 2 batteries. The 90-degree tilting head and support wheels help guide cuts along borders.

See it on Amazon

Pros

  • Trimmer and edger in one tool
  • 2 batteries included
  • Adjustable spacer guard

Cons

  • 12 in cutting diameter
  • Line diameter is 0.065 in

The WORX WG163 is the best fit here if your regular work includes both trimming and lawn borders. It changes from trimmer to edger in seconds, and rubberized wheels help guide the edging cut along a walkway.

Its head tilts 90 degrees, which helps you reach sloped areas and awkward spots. The adjustable spacer guard helps keep the line away from plants and landscape features.

The trimmer weighs 5.5 lb and has a 12 in cutting diameter. WORX includes 2 20V batteries and a charger, and the push-button Command Feed system advances line when you press the button.

Choose it for manageable weight, guided edging and a ready-to-use battery kit. If you prefer automatic line advance without pressing a button, compare the BLACK+DECKER LST300 below.

BLACK+DECKER 20V MAX 2-in-1 Trimmer and Edger: Best for automatic line feed

BLACK+DECKER 20V MAX 2-in-1 Trimmer and Edger, 20V string trimmers
8.8/10Our score
  • 12 in cutting swath
  • Automatic line feed
  • 1 battery and charger included
  • Adjustable height and handle

This trimmer converts to an edger and automatically advances line without bumping. Its adjustable height and handle give you room to set a more comfortable grip.

See it on Amazon

Pros

  • Automatic line feed
  • Battery and charger included
  • Trimmer converts to edger

Cons

  • Only 1 battery included
  • 12 in cutting swath

The BLACK+DECKER LST300 suits buyers who want automatic line feed without bumping. Its 12 in cutting swath and conversion to an edger cover routine trimming and border work.

The included 2Ah battery and charger make this a complete kit. The tool weighs 5.7 lb, and its adjustable height and handle give you options for grip and working position.

BLACK+DECKER describes its battery as providing 33% more runtime per pack than its previous LBXR20 battery. Treat that as a comparison with the named earlier battery, not a guaranteed run time for your yard.

Pick it if automatic feed matters more than having a second battery in the box. If you want a wider cutting path, the CRAFTSMAN 4Ah kit gives you a 13 in swath.

CRAFTSMAN V20 Trimmer and Edger Kit (4Ah): Best for longer stated runtime

CRAFTSMAN V20 Trimmer and Edger Kit (4Ah), 20V string trimmers
8.6/10Our score
  • 13 in cutting swath
  • 4Ah battery and charger included
  • Up to 63 minutes of runtime claimed
  • 2 speed settings

The 4Ah kit pairs a wider 13 in swath with 2 speed settings. CRAFTSMAN claims up to 63 minutes of runtime on low speed with the included battery.

See it on Amazon

Pros

  • Widest swath among the first 3 picks
  • Battery and charger included
  • Turn-to-edge operation

Cons

  • Runtime claim is for low speed
  • Only 1 battery included

The CRAFTSMAN V20 4Ah kit is a good match for buyers who want a wider swath and a stated runtime figure. It cuts a 13 in path and includes a 4Ah battery and charger.

CRAFTSMAN claims up to 63 minutes of runtime per charge when using the included battery on low speed. Two speed settings let you prioritize runtime or power, and Turn-To-Edge changes the tool for lawn edging.

The 13 in swath can cover a broader strip in each pass than the 12 in options above. Choose this kit if that width and its included battery suit your yard; see the brushless CRAFTSMAN next if adjustable width is more useful.

Which 20V trimmer fits your battery and storage needs?

A bare tool can make sense if you already own a compatible battery, while a folding tool may help when storage space is limited. Consider total kit needs alongside cutting width.

CRAFTSMAN V20 RP Brushless Trimmer and Edger Kit: Best for adjustable cutting width

CRAFTSMAN V20 RP Brushless Trimmer and Edger Kit, 20V string trimmers
8.0/10Our score
  • Brushless motor
  • Adjustable 11 in to 13 in swath
  • 5Ah battery and charger included
  • Push-button feed

The brushless kit lets you set an 11 in to 13 in swath and includes a 5Ah battery. Its listed weight is higher than the lighter picks above.

See it on Amazon

Pros

  • Adjustable swath
  • Brushless motor
  • WeatherGuard protection for the tool

Cons

  • 9.4 lb listed weight
  • Up to 75-minute runtime is a brand claim

The CRAFTSMAN V20 RP is the pick for adjusting the cutting path between 11 in and 13 in. Its brushless motor, 5Ah battery and charger come together in a kit, and push-button feed advances line.

CRAFTSMAN claims up to 75 minutes of runtime with this setup. The listed weight is 9.4 lb, so account for that if you expect long sessions or prefer a lighter tool.

WeatherGuard is designed to help protect the tool from moisture and dust. The protection applies to the tool, not the battery or charger.

Choose this one if adjustable swath and a brushless motor matter more than minimizing weight. For a trimming and cleanup pair, the WORX WG928 adds a blower to the kit.

WORX WG928 Trimmer and 360 CFM Blower Kit: Best for trimming and cleanup

WORX WG928 Trimmer and 360 CFM Blower Kit, 20V string trimmers
7.8/10Our score
  • 12 in trimmer and edger
  • 360 CFM blower
  • 2 batteries and charger included
  • Push-button line feed

This kit pairs a 12 in trimmer and edger with a blower for clearing clippings and dry leaves. It suits a buyer who wants both tools in one battery platform.

See it on Amazon

Pros

  • Trimmer and blower in one kit
  • 2 batteries included
  • Push-button line feed

Cons

  • 10.4 lb listed weight
  • More kit than needed if you already own a blower

The WORX WG928 fits buyers who want a trimmer and blower together. Its 12 in trimmer converts to an edger, and the kit also includes a blower rated for up to 360 CFM and 75 MPH.

The push-button Command Feed system supplies line on demand. WORX includes 2 batteries and a charger, so the trimmer and blower arrive as a combined kit for routine yard work and cleanup.

At 10.4 lb, this is the heaviest pick with a stated weight in this roundup. Choose it if you need both tools; if you already own a blower, a standalone trimmer may be easier to store.

DeWalt DCST922B 20V Folding Trimmer (Tool Only): Best for compact storage

DeWalt DCST922B 20V Folding Trimmer (Tool Only), 20V string trimmers
7.7/10Our score
  • 14 in cutting swath
  • Folding hinge
  • Variable-speed trigger and Hi/Lo switch
  • Bare tool

The folding hinge reduces the tool's length for storage and transport. Its 14 in swath is the widest here, but this bare tool does not include a battery or charger.

See it on Amazon

Pros

  • Folding hinge
  • 14 in cutting swath
  • Variable-speed trigger and Hi/Lo control

Cons

  • Battery and charger sold separately
  • Bare-tool setup adds a battery compatibility check

The DeWalt DCST922B is the best fit when compact storage is a priority. Its folding hinge reduces the trimmer’s length by 40% for storage and transport.

A 14 in swath makes it the widest-cutting option in this group. The variable-speed trigger and Hi/Lo switch let you manage output, while the QuickLoad spool is designed for quick line replacement.

This is a bare tool, so the battery and charger are sold separately. Confirm that you have a compatible DeWalt 20V MAX battery before choosing it.

Which 20V trimmers give you more line and battery control?

A 2-speed setting can let you choose between power and runtime, while an automatic or push-button feed changes how you advance line. Check what comes with each tool before comparing features.

BLACK+DECKER 20V MAX LSTE525 Trimmer and Edger: Best for a two-battery kit

BLACK+DECKER 20V MAX LSTE525 Trimmer and Edger, 20V string trimmers
7.6/10Our score
  • 12 in cutting width
  • 2 batteries included
  • 2 speed settings
  • Push-button EASYFEED line advance

The LSTE525 includes 2 batteries and offers 2 speed settings, so you can choose more power or extend runtime. Its EASYFEED button advances line without bumping.

See it on Amazon

Pros

  • 2 batteries included
  • 2 speed settings
  • Converts to wheeled edger

Cons

  • 12 in cutting width
  • Battery capacity is not specified here

The BLACK+DECKER LSTE525 makes sense if you value 2 included batteries and speed control. Choose between 2 speed settings to boost power or extend runtime, and use the EASYFEED button to advance line without bumping the head.

It converts to a wheeled edger and has a 12 in cutting width. The tool weighs 5.3 lb, the lightest stated weight among the picks with listed weights.

The kit includes a charger, guard and spool along with both batteries. Choose it if you want battery backup for a longer session; check battery compatibility if you already own tools in the 20V MAX system.

CRAFTSMAN V20 Trimmer and Edger (Bare Tool): Best for an existing V20 battery

CRAFTSMAN V20 Trimmer and Edger (Bare Tool), 20V string trimmers
7.1/10Our score
  • 13 in cutting swath
  • Automatic line advance
  • 2 speed settings
  • Battery and charger sold separately

This bare tool has a 13 in swath and automatic line advance. Choose it if you already have a compatible CRAFTSMAN V20 battery and charger.

See it on Amazon

Pros

  • 13 in cutting swath
  • Automatic line advance
  • Turn-to-edge function

Cons

  • Battery and charger sold separately
  • No battery runtime figure provided

The CRAFTSMAN CMCST900B is a bare tool for an existing V20 battery setup. It offers a 13 in swath, automatic line advance and 2 speed settings, and turns to edge along lawn borders.

It feeds 0.065 in line without bumping. The box includes the trimmer, spool, auxiliary handle and guard, but the battery and charger are sold separately.

Choose this model if you already have compatible CRAFTSMAN V20 batteries and want a wider cutting path. If you need a complete kit, the CRAFTSMAN 4Ah option above includes the battery and charger.

BLACK+DECKER 20V MAX Resin Blade and String Trimmer Kit: Best for trying resin blades

BLACK+DECKER 20V MAX Resin Blade and String Trimmer Kit, 20V string trimmers
6.9/10Our score
  • Resin blade and string trimming
  • 2 speed settings
  • Battery and charger included
  • On-board storage for up to 6 blades

This kit combines resin blade trimming with a string spool and converts to a wheeled edger. Its stated 5 in cutting width is much narrower than the other picks.

See it on Amazon

Pros

  • Resin blade and string options
  • Battery and charger included
  • On-board blade storage

Cons

  • 5 in cutting width
  • Runtime claim does not specify the speed setting

The BLACK+DECKER resin blade kit is the most specialized pick here. It combines resin blade trimming with a string spool, converts to a wheeled edger and includes a battery and charger.

Its listed cutting width is 5 in, much narrower than the 12 in to 14 in swaths on the other picks. The 2-speed control lets you choose more power or longer runtime, and on-board storage holds up to 6 blades.

BLACK+DECKER claims up to 62 minutes of runtime, but the stated figure does not identify a speed setting. Consider this kit if the resin blade option is the main reason you are shopping.

How to choose a 20V string trimmer for your yard

Choose a 20V trimmer by matching its swath, weight, line feed and battery kit to the shape of your yard and the work you expect to do. These checks help narrow the options before you compare brand platforms.

What cutting width suits a 20V string trimmer?

A wider cutting width can cover more ground per pass, while a narrower one can give you more room around tight borders. This roundup ranges from the 5 in BLACK+DECKER resin blade model to the 14 in DeWalt.

For a typical lawn with walkways and planting beds, a 12 in or 13 in swath is a practical middle ground among these picks. If your yard has many narrow corners, pay attention to head movement and guard design as well as width.

Should you buy a kit or a bare tool?

Buy a kit if you need the battery and charger, and choose a bare tool only when you already have compatible batteries. The DeWalt DCST922B and CRAFTSMAN CMCST900B are bare tools, while the WORX WG163 comes with 2 batteries and a charger.

Battery platform compatibility matters because each brand’s system differs. Read our best 40V string trimmers guide if you are also weighing a higher-voltage option.

Which line feed is easiest to use?

Automatic feed advances line as needed, while push-button feed lets you choose when to advance it. The BLACK+DECKER LST300 and CRAFTSMAN CMCST900B use automatic advance, while the WORX WG163 uses a button-operated system.

A feed style is a matter of preference, but it affects how you handle pauses when line runs short. If you are unsure about line size, see our guide to choosing the right string trimmer line size.

Is a folding shaft useful?

A folding hinge helps when the trimmer must fit in a short storage space or vehicle. The DeWalt DCST922B folds to reduce its length by 40%, making it the clearest option here for compact storage.

A folding design does not replace checking the full dimensions of your storage spot. Measure the available height and length before choosing any trimmer.

Which 20V string trimmer should you choose?

Choose the WORX WG163 for light handling, easy edging and 2 included batteries. Pick the CRAFTSMAN 4Ah kit for a 13 in swath and a stated low-speed runtime, or the DeWalt DCST922B if its folding design and bare-tool setup fit your storage and battery system.

If 20V models do not seem suited to your yard, compare the power tradeoffs in our 40V vs 20V trimmer guide. For another view of DeWalt’s 20V design, read our DeWalt DCST922B review.

Frequently asked questions about 20V string trimmers

Are 20V string trimmers powerful enough for a small yard?

A 20V trimmer can suit a small yard with routine grass trimming and edging, especially when its swath and line feed match the work. Thick growth, a large area or long sessions may call for more runtime or a wider swath.

Compare the yard’s size and grass conditions with our 40V vs 20V trimmer guide.

Does a 20V string trimmer come with a battery?

Some kits include a battery and charger, while bare tools do not. The DeWalt DCST922B and CRAFTSMAN CMCST900B are bare tools, so check that you have a compatible battery and charger before buying.

The WORX WG163, for example, includes 2 batteries and a charger.

What cutting width should I choose for a 20V trimmer?

A wider swath covers more ground in each pass, while a narrower one can help around tight borders and obstacles. The picks here range from 5 in for the resin blade kit to 14 in for the DeWalt DCST922B.

For more on the tradeoffs, see our string trimmer buying guide.

Is a brushless 20V string trimmer worth choosing?

A brushless motor may suit you if runtime and power matter, but compare the full kit, weight and battery platform too. The CRAFTSMAN V20 RP has a brushless motor, adjustable 11 in to 13 in swath, and a 5Ah battery.

Read what a brushless line trimmer is before deciding which features matter.

Can one 20V trimmer edge a lawn too?

Yes. Several picks convert from trimming to edging, including the WORX WG163, BLACK+DECKER LST300 and CRAFTSMAN V20 models.

Some use a wheel to guide the cut along a walkway or lawn border.

Look for a tool with a conversion feature if you want to edge without keeping a separate edger.
