TUAJYUJ 21V 4-in-1 Cordless Trimmer: Best for Attachment Versatility
The TUAJYUJ is different from a basic string trimmer: its listed kit includes several cutting attachments, including nylon blades, steel trimming line, and saw-style blades. The head can be adjusted for edging, while the telescoping handle and adjustable head offer options for changing your reach and working angle.
At a stated 3.5 pounds, it is the lightest option in this comparison. The kit also includes two 4,000mAh batteries, a charger, and protective gear. The product description claims up to 40 minutes of continuous runtime per battery, though actual runtime can vary with the attachment and work conditions.
This design may suit someone who wants one tool for varied yard tasks, rather than a conventional line trimmer alone. It is less straightforward than the WORX and BLACK+DECKER options, which focus on familiar line trimming and edging. The supplied listing data marks this product unavailable, so check its listing before planning a purchase. Also, follow the manual for attachment use and limits; a multi-blade setup calls for extra care around people, plants, and hard surfaces.
Pros:
- Light stated weight of 3.5 pounds
- Includes multiple cutting attachments for different tasks
- Two batteries and a charger are included
- Telescoping handle and adjustable head
Cons:
- Not a conventional spool-feed string trimmer
- Supplied listing data marks it unavailable
Verdict: Consider the TUAJYUJ if attachment variety matters more than a simple line-feed system, but confirm availability and understand the attachments before choosing it for routine edging.
BLACK+DECKER 20V MAX: Best for Simple Automatic Line Feeding
This BLACK+DECKER is a 2-in-1 line trimmer and edger with a 12-inch cutting swath. It converts between the two modes and uses an Automatic Feed Spool system, which advances line as needed without requiring you to bump the tool against the ground.
The listed kit includes one 2.0Ah battery and a wall-mountable charging base. Its adjustable handle and height positions give you ways to tailor the grip, while the product description lists a 6,200 RPM motor speed and a two-year limited warranty.
Its simple conversion and automatic feed make it a practical choice for regular trimming around lawn borders. The cutting swath is narrower than a larger trimmer might offer, which can mean more passes across open areas. The supplied product details do not state a runtime figure, so yard size and the amount of edging you plan to do are worth considering.
Pros:
- Converts between trimming and edging
- Automatic line feed avoids bumping to advance the line
- Adjustable handle and height positions
- Battery and charging base are included
Cons:
- One battery is included
- 12-inch cutting swath may require more passes across wider areas
Verdict: Choose the BLACK+DECKER if you want a straightforward cordless trimmer with automatic line feeding and a clear trim-to-edge conversion.
WORX WG163: Best for Guided, Controlled Edging
The WORX WG163 combines a 12-inch string trimmer with an edging mode. It converts in seconds and has support wheels to help guide the tool along a lawn edge. That extra guidance is useful when you want to keep a steady path beside a sidewalk or driveway.
Instead of relying on automatic line feed, this model uses a push-button Command Feed system. Its head tilts up to 90 degrees for slopes and hard-to-reach spots, and an adjustable spacer guard helps keep the line away from plants and landscape features. The package includes two 20V batteries, a charger, and a spool.
At a listed 5.5 pounds, it weighs more than the lightweight WG154. In return, it offers a second battery and edging wheels, which may matter for longer sessions or anyone who values a guided edge. Its 0.065-inch line and 12-inch cutting diameter are specified, making it easier to compare its basic cutting setup with other choices.
Pros:
- Edging wheels help guide the tool along borders
- Two batteries are included
- Push-button line feed gives you direct control
- Tilting head and spacer guard support careful trimming
Cons:
- Heavier than the WORX WG154
- Line advances by button rather than automatically
Verdict: The WG163 is a strong fit if you want wheels to guide edging and prefer a push-button feed system over automatic line advancement.
ALSO GO 21V Cordless Trimmer: Best for Adjustable Angles
The ALSO GO is a 12-inch cordless line trimmer with a head that rotates for edging. Its product details specify a vertical adjustment range from zero to 90 degrees, which can help when you are working along slopes, corners, or other uneven areas. An automatic line-feed system advances and cuts worn line as you work.
The listed package includes two 2,000mAh batteries, a fast charger, and ten replacement lines. Its stated weight is 5.27 pounds, with an adjustable auxiliary handle for changing your grip. The description also lists a 9,500 RPM motor, though the cutting width and battery capacity are more useful details for comparing the tool’s fit to your yard.
This model may suit someone who wants an adjustable head and automatic feeding without stepping up to a multi-attachment tool. The product information does not provide a runtime estimate, so two included batteries are a useful feature but do not guarantee a particular amount of work time. The listed weight is also higher than both WORX options.
Pros:
- Rotating head supports trimming and edging
- Automatic line feed
- Two batteries and ten replacement lines are included
- Auxiliary handle adjusts to support different grips
Cons:
- Heavier than the two WORX models listed here
- Runtime is not specified in the supplied product details
Verdict: Consider the ALSO GO if adjustable head angles and automatic line feeding are priorities, while keeping its stated weight and unspecified runtime in mind.
WORX WG154: Best Lightweight Pick for Small to Medium Yards
The WORX WG154 is a compact 2-in-1 trimmer and edger designed for routine yard maintenance. It weighs 4.2 pounds and switches between trimming and in-line edging by rotating the head. Automatic line feed helps keep you working without manually bumping the tool to advance the line.
An adjustable flower guard helps protect plants, ornaments, and landscape features when you trim close to them. The kit includes a 20V 2.0Ah battery, charger, spool, and safety guard. The battery is part of the WORX Power Share system, which works with WORX 20V tools and select 40V and 80V tools.
The WG154 is the lightest traditional line-trimmer option in this comparison, making it a sensible choice for quick edging and trimming jobs. Its product details do not state a cutting width or runtime, and the package includes one battery. For larger yards or longer sessions, the WG163’s two-battery kit may be a better fit.
Pros:
- Light stated weight of 4.2 pounds
- Converts between trimming and in-line edging
- Automatic line feed and adjustable flower guard
- Battery works within the WORX Power Share system
Cons:
- One battery is included
- Cutting width and runtime are not stated in the supplied details
Verdict: Pick the WG154 for light, routine trimming and edging, especially if you already use compatible WORX batteries.
How to Choose a Battery String Trimmer for Edging
Check How the Tool Switches to Edging Mode
Look for a head or shaft that changes position without a complicated setup. The products here use rotating or adjustable heads to move from horizontal trimming to vertical edging. If you need to follow long stretches of sidewalk or driveway, support wheels like those on the WORX WG163 can help guide the tool. For corners and slopes, a head that tilts may be more useful.
Choose a Line-Feed System You Prefer
Automatic line feed advances line as needed, which can reduce stops to adjust it by hand. A push-button feed gives you more direct control over when line advances. Both approaches can work well; your choice depends on whether you prefer fewer manual steps or control over line use. The TUAJYUJ differs from these conventional spool systems because its kit includes several blade and line-style attachments.
Match Cutting Width to Your Yard
A wider cutting swath covers more ground with each pass, while a narrower swath can be easier to control around tight borders and obstacles. The BLACK+DECKER, WORX WG163, and ALSO GO list 12-inch cutting widths or diameters. The supplied details do not state a cutting width for the TUAJYUJ or WORX WG154, so compare the product listing if that measurement is important to you.
Consider Weight and Handle Adjustments
Edging requires you to guide the tool along a border, so weight and balance can affect comfort. Among the listed models, the TUAJYUJ has a stated weight of 3.5 pounds and the WORX WG154 weighs 4.2 pounds. The other products weigh more than five pounds according to their supplied details. Adjustable handles and shafts can also help you find a more comfortable working position.
Think About Batteries and Runtime
Check how many batteries come with the trimmer, their listed capacity, and whether they work with tools you already own. The WORX models use the Power Share platform, and the BLACK+DECKER includes a 2.0Ah battery. The TUAJYUJ and ALSO GO include two batteries each. Runtime is not specified for every model, so battery count alone is not a reliable way to predict how long a job will take.
Look at Guards and Included Accessories
A spacer or flower guard can help keep the cutting line away from plants and lawn ornaments. Also check the package contents for a charger, replacement spool or line, and other parts you need. If you choose a tool with blade attachments, read its instructions carefully and use only the attachments and cutting methods approved for that model.
Frequently Asked Questions
Can a battery string trimmer also edge a lawn?
Yes. The products in this guide include an edging mode, usually by rotating or repositioning the head so the cutting line runs vertically along a border. Check the tool’s instructions for the correct conversion method.
What is the difference between automatic and push-button line feed?
An automatic system advances line as needed while you work. A push-button system lets you trigger line feed when you want it. Neither approach is best for every user, so choose based on how much control you want over line advancement.
Which option is the lightest?
The TUAJYUJ lists a weight of 3.5 pounds, but it uses multiple cutting attachments rather than only a conventional spool-feed system. Among the traditional line trimmers, the WORX WG154 is the lightest listed at 4.2 pounds.
Do these trimmers include batteries and chargers?
The supplied product details list batteries and chargers with all five models. The battery count and capacity differ, so check the included-items list for the exact package you plan to buy.
Is a wider cutting swath always better for edging?
Not always. A wider swath can cover more grass per pass, but a smaller or more carefully guided cut may be easier around narrow beds, corners, and other tight spaces. Edging control and the tool’s head design also matter.
Which trimmer is best for following a straight sidewalk edge?
The WORX WG163 stands out for this task because it includes rubberized support wheels that guide the edger. A steady pace and careful alignment are still important for a clean line.
Final Recommendation
For most shoppers who want a conventional battery string trimmer with useful edging guidance, the WORX WG163 is the most balanced choice in this group: it has a 12-inch cutting diameter, support wheels, push-button line feed, and two included batteries. Choose the lighter WORX WG154 for simpler, routine yard work, or the BLACK+DECKER if automatic line feeding is your priority. Before buying, compare the included battery setup and verify that the tool’s edging method fits your yard.
