Best Cordless Grass Trimmers for Trimming and Edging

#1 · Best Overall

1. WORX WG163

• Dimensions L x W: 44.6"L x 35"W
• Weight: 5.5 lb
• Size: 20V GT 3.0 Trimmer / Edger

Best for: For edging and sloped lawns.

Why it ranks #1: Its 12-inch head converts between trimming and edging, tilts 90 degrees, and uses push-button line feed; the kit includes two batteries and an edger wheel.

The WG163 switches from string trimming to in-line edging in seconds, letting one cordless tool handle lawn borders as well as grass cleanup. Its 90-degree tilting head adds reach on slopes and in awkward spots, while rubberized wheels help guide the edger for straighter lines along walkways.

A push-button Command Feed spool advances line on demand, so you can replenish it without stopping to bump the head. When edging, the rubberized wheels support and guide the tool, helping keep cuts straighter; the head also tilts 90 degrees for sloped terrain and hard-to-reach areas. The package includes two batteries, a charger, an edger wheel, and a flower guard, giving buyers the components for switching between edging and trimming around garden beds.

Skip it if you need a wider stated cutting path; the WeGofly WEG21T lists a 13-inch size, compared with this tool’s 12-inch size.

Choose the WORX WG163 for routine grass trimming and guided edging, especially where sloped ground or tight spots need attention. Its 12-inch size and wheel-guided edge mode suit focused yard work rather than a wider cutting path.

#2 · Best Mini-Mower

2. WORX WG170

• Dimensions L x W: 45.1"L x 37.4"W
• Weight: 5.5 lb
• Size: 12 in

Best for: For trimming, edging, and narrow strips.

Why it ranks #2: This 12-inch tool handles trimming, edging, and mini-mowing, with seven handle adjustments, six rotating head settings, Command Feed, and two included batteries.

The WORX WG170 adds a mini-mower mode to its trimmer and in-line edger functions, letting one cordless tool reach narrow lawn strips that a main mower may miss. Seven handle adjustments and six rotating-head settings offer multiple working positions for changing tasks and comfort.

Command Feed line advancement adds line at the push of a button, so a depleted cutting line need not bring trimming to a stop for manual bumping. The three modes cover string trimming, in-line edging, and mini-mowing, including narrow strips beyond a main mower’s reach. Seven handle adjustments and six head settings help tailor the tool’s position across those jobs. The package lists two batteries and a charger; charging time is stated as five hours.

Skip it if you want a stated shorter charging time; the BLACK+DECKER LST300 listing does not specify one, so compare its supplied kit details.

The WG170 fits buyers who want trimming, edging, and mini-mowing for narrow strips in one cordless tool. Its five-hour stated charging time is a planning consideration, particularly if you expect to recharge between yard-work sessions.

• Dimensions L x W: 41.33"L x 9.25"W
• Weight: 5.7 lb
• Size: 12"

Best for: For longer jobs with speed control.

Why it ranks #3: Its included 2.5Ah battery is listed as offering 66% more runtime than standard models, while two speed settings balance cutting power and runtime.

The LST522 pairs a 2.5Ah battery with two-speed control, so you can select higher power for tougher patches or lower speed for longer edging sessions. Automatic line advancement feeds as you work, making this cordless trimmer a practical fit for varied yard tasks without bumping the head.

BLACK+DECKER states that the included LBXR2520 battery offers 66% more runtime than standard models, a useful distinction for larger projects. Two speed settings let you prioritize power on tough areas or runtime during extended work, while the AFS system advances line automatically to avoid stopping for manual feed. The tool is also described as a trimmer and wheeled edger, giving buyers a way to switch from lawn cleanup to border work with the same kit.

Skip it if you require a clearly listed charger in the package; the BLACK+DECKER LST300 explicitly includes one.

Choose the LST522 for trimming and wheeled edging across jobs that benefit from switching between higher power and longer-runtime settings. Its supplied specifications do not identify a charger in the package, so check the included equipment details before choosing.

• Dimensions L x W: 36.23"L x 8.5"W
• Weight: 5.7 lb
• Size: One Size

Best for: For simple trim-and-edge routines.

Why it ranks #4: The 12-inch trimmer converts to a wheeled edger, has automatic line feed, and includes a 20V battery and charger for a ready-to-use kit.

BLACK+DECKER’s POWERDRIVE transmission delivers motor power to the cutting string, while its 2-in-1 design converts to edging in seconds. That combination suits homeowners who want one cordless tool for grass and borders, with automatic line feeding that avoids the need to bump the head during work.

The AFS spool automatically feeds line when needed, keeping the trimming workflow moving without manual bumping. For lawn borders, the tool converts from trimmer to edger in seconds, and the included battery and charger make it a ready-to-use cordless kit. BLACK+DECKER lists a 12-inch steel deck, a lightweight 5.7-pound body, and an adjustable handle; together, these specifications support manageable handling for routine edging and trimming around the yard.

Skip it if you want a wider listed cutting path; the WeGofly WEG21T has a 13-inch size, while this BLACK+DECKER is 12 inches.

This LST300 fits buyers seeking a lightweight cordless trimmer and edger for everyday grass and border upkeep. Its 12-inch deck and included battery kit are practical boundaries to weigh if your lawn calls for a wider cutting path.

#5 · Most Versatile

5. WeGofly 4-in-1

• Dimensions L x W: 33"L x 8"W
• Size: 13-Inch

Best for: For multi-task yard cleanup.

Why it ranks #5: Its listed functions cover string trimming, edging, mini-mowing, and brush cutting; the package includes two 21V 6.0Ah batteries and a charger.

Four working modes—string trimmer, edger, mini lawn mower, and brush cutter—let the WeGofly WEG21T cover several kinds of yard cleanup with one tool. Its package includes two 21V 6.0Ah batteries and a charger, while the listed 13-inch size gives it a wider stated path than 12-inch models.

The four-in-one setup can shift from trimming grass to edging, mini-mowing, or cutting brush, so one tool addresses different small-yard tasks. Two 21V 6.0Ah batteries and a matched charger are supplied for extended use without frequent charging, according to the listing. WeGofly also describes steel gears and a 5.2-pound weight; these details matter to buyers considering the tool’s construction and handling across its multiple modes. A storage bag holds accessories, screws, and blades after use.

Skip it if you prioritize the lowest listed weight; the MLKXCVB HY-71 weighs 3.8 pounds, compared with this tool’s 5.2 pounds.

The WEG21T suits buyers who want one cordless tool for trimming, edging, mini-mowing, and brush cutting, with spare battery capacity included. Its 5.2-pound weight is worth considering if lighter handling matters more than its extra modes.

Listed on Amazon as: 13" Electric Weed Wacker, 4 in 1 Cordless String Trimmer/Lawn Edger/Lawn Mower/Brush Cutter with Steel Gears, 2×21V 6.0Ah Batteries & Charger, 5.2 LBS Lightweight Grass Trimmer for Yard Garden

#6 · Best for Storage

6. KOMASTY Foldable Trimmer

• Dimensions L x W: 40"L x 8"W
• Size: 12 in

Best for: For compact garage storage.

Why it ranks #6: The shaft folds 180 degrees for compact storage, and the head adjusts 90 degrees; its 12-inch cutting capacity and two 2.0Ah batteries suit routine lawn trimming.

The KOMASTY’s shaft folds 180 degrees in three ways for vertical storage, making it a useful fit for tight corners, apartments, or crowded garages. Its 90-degree adjustable head and 180-degree rotatable handle add working positions for slopes, under-bench areas, and other hard-to-reach spots.

A 9,500-RPM motor and 12-inch size are specified for regular lawn trimming, while two 2.0Ah batteries and a charger come with the tool. The adjustable head and rotatable handle can help reach slopes and areas beneath benches without forcing the same position throughout a job. Folding the shaft in three ways supports compact vertical storage after use. The listing cautions that the tool is intended for regular lawn grass, not excessively thick, wet, or overgrown growth.

Skip it if you regularly cut thick, wet, or overgrown grass; the WeGofly WEG21T lists a brush-cutter mode for broader yard tasks.

The KOMASTY fits buyers who need a cordless trimmer that stores vertically and adjusts for slopes or under-bench work. Keep its stated limitation in mind: it is intended for regular lawn grass, not thick, wet, or overgrown growth.

7. HortiHub Cordless Trimmer

• Dimensions L x W: 47.24"L x 11.81"W
• Weight: 5.3 lb
• Size: Medium

Best for: For small-yard grass trimming.

Why it ranks #7: This 5.3-pound trimmer lists a 9,000-RPM cutting head, automatic line feed, and trimming, edging, and brush-cutting uses for general yard maintenance.

A 9,000-RPM cutting head gives the HortiHub HG0556-AOR its stated high-speed cutting action for thick grass and lawn edges. Automatic line feed advances line as you trim, while its 5.3-pound weight and cordless format suit everyday maintenance in small yards and garden areas.

The automatic feed system releases 0.4–0.5 inches of line as the tool works, helping maintain cutting line without stopping for manual adjustment. HortiHub also lists an optimized motor and acoustic-dampening design, supporting its description of reduced operating noise for yard work. Tool-free assembly is stated to get the unit ready in minutes, and the adjustable handle allows a more tailored grip. The listing also says impact-resistant goggles and a safety guard are included.

Skip it if you need a stated battery capacity or runtime before choosing; the BLACK+DECKER LST522 lists a 2.5Ah battery.

Consider the HortiHub for small-yard trimming and everyday garden edges if automatic line feed and tool-free assembly match your workflow. Its supplied specifications leave battery capacity and runtime unstated, a relevant limit for planning longer sessions.

8. MLKXCVB Cordless Trimmer

• Dimensions L x W: 34.6"L x 6.2"W
• Weight: 3.8 lb

Best for: For lightweight cordless handling.

Why it ranks #8: It weighs 3.8 pounds and includes two 21V batteries, detachable wheels, and a 90-degree adjustable head, though the listing omits cutting width.

At a listed 3.8 pounds, the MLKXCVB HY-71 is the lightest-weight option in this group with a stated weight. Its 90-degree adjustable head and detachable wheels offer additional ways to handle trimming, while two 21V lithium batteries and a fast charger come in the package.

The 880W pure-copper motor is listed with a no-load speed up to 18,000 RPM, and the tool is described as a 3-in-1 cordless weed eater. Detachable wheels can support a wheeled approach to yard work, while the adjustable head changes the working angle for different areas. Two removable batteries and a fast charger are included; swapping batteries can extend operation without waiting for a single battery to recharge, according to the product description.

Skip it if you need a stated battery capacity or runtime for planning; the BLACK+DECKER LST522 specifies a 2.5Ah battery.

Choose the HY-71 if a low listed weight, detachable wheels, and swappable batteries suit your cordless yard routine. Its specifications do not state battery capacity or runtime, so those details remain a boundary for planning extended work.

#9

9. Panbemer 48V Trimmer

• Dimensions L x W: 33"L x 6"W
• Weight: 4 lb

Best for: For cordless weed and twig cleanup.

Why it ranks #9: The listing identifies a 48V cordless string trimmer weighing four pounds, but gives fewer concrete details about its cutting width, line feed, or included kit.

Panbemer’s listed 48V lithium power system is paired with claimed cutting torque for thick weeds, overgrown grass, and small twigs. At a stated four pounds, this cordless trimmer suits buyers seeking a lightweight option for those cleanup tasks without gas, fuel mixing, or power cords.

The battery-powered design removes the need for fuel mixing and cords, simplifying setup for yard work where an outlet or gas supply is inconvenient. Panbemer says the 48V system delivers torque for thick weeds, overgrown grass, and small twigs, extending its stated use beyond routine lawn edges. Its compact 33-by-6-inch dimensions and four-pound listed weight are relevant for handling and storage. The supplied details do not specify battery capacity, runtime, or cutting width.

Skip it if you need stated battery capacity or runtime; the BLACK+DECKER LST522 lists a 2.5Ah battery for comparison.

The Panbemer suits buyers seeking a lightweight cordless tool for weeds, overgrown grass, or small twigs, without fuel mixing. Its supplied details do not state runtime or cutting width, so it is a less specific fit for planning coverage.

#10

10. CRAFTSMAN CMCSS800C1

• Dimensions L x W: 7.27"L x 3.13"W x 12.13"H

Best for: For garden beds and shrub touch-ups.

Why it ranks #10: This is a handheld grass shear and hedge trimmer rather than a string trimmer, with 4-inch and 8-inch blades for precise garden-bed and shrub work.

The CRAFTSMAN CMCSS800C1 switches between an 8-inch shrubber blade and a 4-inch grass-shear blade, covering shrub touch-ups and precise cleanup around beds. Its handheld format and included V20 1.5Ah battery and charger make it a different kind of cordless option from full-size string trimmers.

The 8-inch blade handles shrub trimming, while the 4-inch blade is intended for fescues and garden-bed cleanup, letting one compact tool address two detail-cutting jobs. Blade changes are described as quick, so switching between the shrubber and grass shear is part of the workflow. CRAFTSMAN specifies cuts up to 5/16 inch deep with the hedge clippers. The included 20V 1.5Ah battery and charger complete the kit, though its handheld blades suit precise work rather than broad string-trimmer passes.

Skip it if you need broad grass-trimming passes; the WORX WG163 is a 12-inch cordless string trimmer and edger.

Choose the CRAFTSMAN for precise shrub touch-ups, fescues, and garden-bed cleanup rather than covering broad lawn areas. Its 8-inch and 4-inch blades suit detail work, so a full-size string trimmer is a better fit for wider passes.
