Homeowners and landscapers frequently struggle with uneven edges, overgrown weeds along fences and walkways, and the physical strain of outdated tools when searching for a reliable Black & Decker String Trimmer Edger. Common pain points include limited cutting reach on thick grass, battery fade mid-job on cordless units, cord management issues on electric models, and the ongoing cost of replacement line that jams or breaks too easily. Selecting among the many BLACK+DECKER options and compatible accessories requires matching power output, cutting diameter, and feed systems to yard size and terrain type so that weekly maintenance stays efficient rather than exhausting.
When evaluating black & decker string trimmer edger options in August 2026, prioritize cutting width of 12-13 inches, power source (corded 5-amp or cordless 20V-40V MAX), automatic or easy-feed string systems, and overall tool weight under 10 pounds for reduced fatigue. These factors, combined with battery inclusion and spool compatibility, determine real-world performance across the 7 models we analyzed from BLACK+DECKER, Eventronic, YWTESCH. Readers seeking broader context can start by reviewing core specifications of edgers before narrowing to string trimmer hybrids.

Drawbacks & Considerations: The main limitation is compatibility, since it is intended for specific BLACK+DECKER models rather than all trimmers. The 0.065-inch line is also best suited to lighter trimming jobs, so users with tougher vegetation may want a more heavy-duty solution.

- Included fast charger reaches a full charge in two hours or less
- Battery level indicator and no-bump auto-feed spool add everyday convenience
- Backed by a 3-year limited warranty
Cons
- Ships with a single 2.0Ah battery, which may limit runtime for very large yards
- 13-inch cutting swath is better suited to residential lawns than heavy commercial use
- Battery-powered performance depends on charge level and PowerCommand seting selected
The BLACK+DECKER LST136 is a 40V MAX cordless string trimmer and edger built for homeowners who want gas-free, low-maintenance lawn care. It features a 13-inch cutting swath, an adjustable telescoping pole, and a soft-grip handle, so users of varying heights can find a comfortable working position. The kit arives complete with the LBX2040 2.0Ah lithium-ion battery, LCS40 fast charger, AF-100 spool, guard, and auxiliary handle.
Performance is driven by the PowerDrive transmission, which sends more motor power to the cutting string, and speds reach up to 8500 RPM for efficient cutting. The PowerCommand dial lets you prioritize maximum power for thick weeds or maximum runtime for larger areas. The Automatic Feed Spool advances line without bumping, while the state-of-charge indicator keeps you aware of remaining battery. Conversion from trimmer to edger takes only seconds, making border work along paths quick and clean.
There are trade-offs to consider. The tool includes a single 2.0Ah battery, so owners with larger properties may want a spare to avoid downtime while recharging. The 13-inch swath and battery platform are best matched to residential lawns rather than sustained commercial workloads, and effective runtime will vary with the PowerCommand setting and battery charge.
Verdict: The LST136 is a strong fit for homeowners seking a versatile, quiet, and easy-to-maintain 2-in-1 trimer and edger. Buyers with small to medium yards will get the most value, especially those who appreciate the fast charger, auto-feed convenience, and the reassurance of a 3-year limited warranty.
Pros

The BLACK+DECKER LSTE523 20V MAX String Trimmer and Edger is a cordless 2-in-1 tool designed for everyday lawn upkeep. It features a 12-inch cutting width, an adjustable-height shaft, and a soft-grip handle that improves comfort and control for a range of users. As part of the 20V MAX system, it ships with the LB2X3020 extended-runtime lithium battery, a charger, an AFS spool, and a guard.
Performance and key features center on convenience and control. The standout EASYFEED system advances trimmer line with the push of a button, removing the need to bump the head against the ground. A 2-speed control lets you dial up power for thicker weeds or drop down to stretch runtime, while the PowerDrive Transmission increases torque at the string for stronger cuting. The tool also converts into a wheeled edger for clean borders along walkways and beds.
Drawbacks and considerations are typical of a compact cordless trimmer. The 12-inch swath and battery-based power make it ideal for small to medium lawns rather than large lots or heavy brush. Because it includes a single battery, extended sessions may require a recharge break, and gas users should expect lighter-duty cutting performance.
Verdict: This trimmer is a solid pick for homeowners with small to mid-sized yards who value low-maintenance, cordless operation and want the flexibility of an integrated edger. The EASYFEED line system and 2-speed control make routine trimming simpler, and the 2-year limited warranty ads peace of mind.
Pros

Performance & Key Features: Each spool measures 30 ft and is made from polyamide nylon designed for flexibility and abrasion resistance. The product is positioned for everyday lawn maintenance, with line that can cut grass and light weeds while helping reduce drag during use. The included extra caps and springs add convenience if those parts also need replacement.
Drawbacks & Considerations: This is a compatibility-specific accessory, so buyers need to confirm their Black+Decker model before ordering. The 0.065-inch line is suitable for routine trimming, but it is not the strongest choice for dense brush or very heavy vegetation.
Verdict: This pack offers good value for homeowners who need an easy-to-install refill for a compatible Black+Decker trimmer. It is most useful for regular yard cleanup, fast spool swaps, and users who prefer pre-wound convenience over manual line loading.
Black & Decker String Trimmer Edger Buying Guide
Choosing the right Black & Decker String Trimmer Edger depends on matching technical attributes to property size, user strength, and maintenance habits. Below are the core criteria derived from specification comparison of 7 current models spanning $8.88 – $159.00.
Power Source and Voltage or Amperage
Power source determines runtime freedom versus consistent output. Cordless units in the lineup operate on 20V MAX or 40V MAX lithium-ion platforms and typically include the battery and charger, making them suitable for medium yards without nearby outlets. Corded models such as the 5-amp electric version deliver uninterrupted power but require extension cord management and limit reach to the cord length. For properties larger than a quarter acre, 40V systems provide higher torque for denser vegetation while 20V options balance lighter weight with adequate performance on standard turf. Always verify battery amp-hour rating when listed, as higher Ah extends continuous runtime before recharging.
Cutting Width and Dual Trimmer-Edger Functionality
Most models offer 12-inch or 13-inch cutting paths that rotate or pivot into a vertical edger position for clean sidewalk borders. Wider 13-inch heads cover more ground per pass and reduce total trimming time on expansive lawns, while 12-inch heads improve maneuverability around flower beds and tight corners. Dual 2-in-1 designs allow a single tool to handle both horizontal weed whacking and vertical edging, eliminating the need for a separate edger. Confirm the head-lock mechanism holds securely at 90 degrees to avoid mid-job adjustments that interrupt workflow.
String Feed System and Line Diameter Compatibility
Automatic or EasyFeed systems advance fresh 0.065-inch diameter line without bumping the head on hard surfaces, reducing operator effort and protecting pavement. Manual bump-feed remains common on budget units and works reliably once the technique is learned. Aftermarket multipacks from Eventronic and YWTESCH supply compatible AF-100 style spools plus spare caps and springs, ensuring long-term ownership costs stay low. Match the exact diameter and auto-feed design of the original spool to prevent jams. Stocking genuine or high-quality compatible line is essential because low-grade string frays faster against concrete and fences.
Weight, Ergonomics, and Adjustable Shaft
Tools under 8-10 pounds with telescoping poles and adjustable handles reduce shoulder and back strain during extended sessions. Wheeled edger variants transfer weight to the ground for precise straight edges with minimal lifting. Look for soft-grip handles and balanced battery placement that keep the center of gravity near the user. Height-adjustable shafts accommodate operators of different statures and allow comfortable two-handed control when converting between trim and edge modes. Lightweight construction becomes critical for users managing large properties or those with limited upper-body strength.
Included Accessories and Long-Term Value
Many cordless kits ship with a battery, charger, and at least one spool, lowering the initial barrier. Replacement line multipacks priced near the lower end of $8.88 – $159.00 extend tool life economically. Evaluate warranty length and brand support, as BLACK+DECKER maintains widespread parts availability. Value improves when the same battery platform works across other lawn tools already owned. For pure accessories, multipacks offering eight spools plus caps and springs deliver the lowest cost per foot of line while remaining fully compatible with AF-100 systems used by the main trimmers.
The table below compares three core BLACK+DECKER models on key measurable attributes drawn from published specifications. Users reviewing the full category of edgers will notice similar trade-offs between power and portability.
| Model | Power Source | Cutting Width | Key Feature |
|---|---|---|---|
| BLACK+DECKER 40V MAX LST136 | 40V MAX Cordless | 13 inch | Telescoping pole, battery included |
| BLACK+DECKER 20V MAX LST522 | 20V MAX Cordless | 12 inch | Wheeled edger, 2-speed PowerDrive |
| BLACK+DECKER ST8600 | 5-Amp Corded | 13 inch | Continuous power, lightweight |
Testing & Selection Methodology
We compared 7 models by systematically reviewing manufacturer specifications for voltage or amperage, cutting diameter, feed mechanism type, included battery or charger status, and line diameter compatibility. Weight and shaft adjustability were noted from product dimensions where available. Brand reliability was assessed through established market presence of BLACK+DECKER alongside aftermarket support from Eventronic and YWTESCH for consumables. User satisfaction metrics and warranty terms were cross-checked against publicly listed details rather than anecdotal claims. Models were ranked by how well their published specs addressed common yard tasks: open-area trimming, edge definition, and ongoing line replacement cost. No physical lab testing was performed; rankings reflect objective data density and real-world utility alignment for typical residential use cases in 2026.
Selection prioritized complete kits that reduce extra purchases and multipacks that lower consumable costs. Products lacking clear voltage, width, or compatibility data were deprioritized. This process yields transparent, specification-driven recommendations that remain current through the dynamic placeholder system.
Best Picks & Final Verdict
After evaluating the full set of 7 options spanning $8.88 – $159.00, clear winners emerge for different buyer priorities. The top recommendations balance published power ratings, cutting performance, and accessory ecosystem without relying on unsubstantiated claims.
Best Overall Black & Decker String Trimmer Edger: BLACK+DECKER 40V MAX 13 in String Trimmer Edger Cordless with Adjustable Telescoping Pole (LST136). Its higher 40V platform paired with a full 13-inch path and telescoping shaft delivers the strongest combination of runtime potential and reach for medium to large yards while including battery and charger. The dual trimmer-edger conversion supports complete perimeter maintenance in one tool.
Best Value / Budget Choice: BLACK+DECKER String Trimmer / Edger, 13-Inch, 5-Amp (ST8600). This corded model provides continuous 5-amp power and a full 13-inch width at the lower end of the spectrum, eliminating battery replacement concerns for users with ready access to outlets. It remains lightweight and effective for standard residential lots.
Best for Easy Edge Definition: BLACK+DECKER 20V MAX 12 Inch Weed Eater Cordless String Trimmer and Wheeled Edger (LST522). The wheeled base transfers weight to the ground for straighter edges with less physical effort, while the 2-speed PowerDrive and included 2.5Ah battery suit users prioritizing comfort and controlled edging. For ongoing supply, the Eventronic or YWTESCH 10-pack AF-100 compatible spools keep the tool running at minimal cost. Those researching related tools may also consult the main edgers category for complementary options.
Frequently Asked Questions
What cutting width works best for most residential black & decker string trimmer edger tasks?
A 12-inch to 13-inch cutting width handles typical residential lawns efficiently by balancing coverage speed with control around obstacles. Wider 13-inch heads reduce passes on open areas while 12-inch heads improve precision near beds and fences. Most models in this review use these diameters for versatile performance.
How do I choose between cordless and corded black & decker string trimmer edger models?
Choose cordless 20V or 40V MAX units when mobility across large or obstacle-filled yards is essential and the included battery provides sufficient runtime. Select corded 5-amp models for continuous power without recharging when an outdoor outlet and extension cord are practical. Both types convert to edger mode on the reviewed BLACK+DECKER designs.
What string diameter and feed type should I use with these trimmers?
Use 0.065-inch diameter line with automatic or EasyFeed systems for jam-resistant operation that advances line without hard bumping. Compatible multipacks from Eventronic and YWTESCH supply AF-100 style spools that match original equipment. Stocking spare spools, caps, and springs ensures uninterrupted work.
Are replacement spools from Eventronic and YWTESCH reliable for BLACK+DECKER tools?
Yes, the listed multipacks are designed as direct AF-100 compatible replacements offering multiple spools plus caps and springs at the lower end of $8.88 – $159.00. They maintain automatic feed function when installed correctly. Users comparing full options can review the complete edgers selection for additional context on maintenance parts.
How often should I replace the string on a black & decker string trimmer edger?
Replace the string whenever it becomes too short for effective cutting or shows excessive fraying after contact with hard surfaces, typically every few sessions depending on yard size and vegetation density. Keeping multipack spools on hand minimizes downtime. Automatic feed systems help maximize usable length per spool.
