Homeowners and landscapers often struggle with overgrown grass along fences, sidewalks, and garden borders, where a standard mower falls short and a dedicated gas tool proves too heavy or noisy for quick weekly maintenance. Selecting the right string trimmer and edger means balancing cordless runtime against cutting power, avoiding models that tangle line constantly or tip over on uneven ground, and finding a tool light enough for extended use without arm fatigue. In our evaluation of current options, we focused on dual-function designs that switch from horizontal trimming to vertical edging in seconds, because this versatility reduces the need for multiple pieces of equipment and keeps storage simple in garages or sheds. Many buyers also overlook battery platform compatibility, which can lock them into expensive proprietary packs if they later expand their tool collection.
In August 2026, the most important factors when choosing a String Trimmer And Edger are battery voltage and capacity for uninterrupted runtime, cutting diameter combined with automatic or command line feed for consistent performance, overall weight under 6 lbs for reduced fatigue, and true 2-in-1 or 3-in-1 conversion capability with support wheels for clean edges. We analyzed 9 leading cordless models from WORX, BLACK+DECKER, Greenworks and more based on motor RPM, included batteries, adjustable shafts, and real-world utility metrics to identify clear winners across budgets. For a broader look at complementary lawn tools, start by reviewing the full selection available in the edgers category to match your specific yard size and terrain.
Pros

The WORX WG163 is a cordless 20V string trimmer and lawn edger built for residential use. Weighing just 5.5 lbs with a compact design, it features rubberized wheels and an adjustable spacer guard that create a solid first impression of a user-friendly outdoor power tool focused on precision and ease.
In performance the 7600 rpm motor and 12 inch cutting diameter handle standard grass trimming effectively. The innovative command feed allows instant line deployment with a push button while the head tilts up to 90 degrees for slopes and tight spaces. Conversion from trimmer to edger takes only seconds and the two included Power Share batteries support the broader WORX ecosystem for ongoing convenience.
Potential drawbacks include the 12 inch path that can slow progress on expansive lawns and the 0.065 inch line suited mainly to lighter tasks. Battery runtime is not detailed in specs so users may need to plan around recharges for prolonged sessions.
Overall the WORX WG163 delivers strong value for homeowners managing small to medium yards who want a convertible cordless tool with ecosystem compatibility and straightforward operation.

The included 2.0Ah battery and fast charger that tops up in 1 hour 20 minutes support efficient sessions without pull-cord frustration.
Considerations include the single battery pack, which may need recharging during longer jobs, and the 12-inch diameter that makes the tool less ideal for expansive properties. Users should also plan for eventual spool replacements after the eight factory lines are used.
Overall the LPSUK 20V Cordless String Trimmer delivers the strongest value to homeowners seeking a lightweight, multi-function cordless solution for routine yard maintenance. It is especially well suited for seniors, beginners, and those with modest lawns who prioritize comfort, ease of use, and clean edges without the complexity of larger machines.

Verdict: The Greenworks 40V Gen 2 is a solid choice for homeowners who want a low-noise, low-maintenance trimmer and edger for regular yard upkeep.

Simply rotate the tube 90° to switch modes, and the spacer guard helps protect plants during operation across various yard surfaces.
Potential drawbacks include the roughly 30-minute battery life that may fall short for extensive properties, requiring mid-job swaps or charges, along with the need to replace string spools over time despite the six included units. As a cordless model, it emphasizes convenience and reduced maintenance over the raw continuous output of gas tools.

String Trimmer And Edger Buying Guide
Choosing among the current string trimmer and edger options requires matching technical specifications to your yard size, typical grass thickness, and physical comfort needs. The following criteria draw directly from the motor speeds, battery packages, and conversion mechanisms found across the 9 models we examined.
Battery Voltage, Capacity, and Runtime
Battery systems form the foundation of any cordless string trimmer and edger. Most models in this group use 20V platforms with 2.0Ah packs, delivering 30 minutes of total runtime when two batteries are included, which suits small to medium yards under 5,000 square feet. Higher-voltage options such as the 40V Greenworks unit extend continuous cutting to around 40 minutes and handle denser weeds more effectively. Always check whether the charger supports 1-hour fast charging and whether spare batteries are interchangeable with other tools from the same brand, as this multiplies long-term value. For larger properties, prioritize dual-battery kits that allow hot-swapping without downtime.
Cutting Diameter, Motor Speed, and Line Feed System
A 12-inch cutting swath paired with motors spinning between 7,600 and 9,500 RPM clears grass efficiently while remaining maneuverable around obstacles. Automatic line feed or push-button command feed systems eliminate the need to bump the head on the ground, which frequently causes jams or uneven line lengths. Models that include multiple spare spools or free-for-life line programs reduce ongoing costs. Look for 0.065-inch line diameter as a balance between durability and reduced vibration. Wider 13-inch heads, found on select higher-end units, finish larger areas faster but can feel less precise for tight edging along flower beds.
Weight, Ergonomics, and Adjustability
Units weighing 5 to 5.5 lbs minimize fatigue during sessions longer than 20 minutes and remain accessible for users of varying strength. Telescopic shafts that extend from 38 to 49 inches, combined with 180-degree rotating handles and 60- to 90-degree pivoting heads, allow comfortable operation on slopes or under low fences without stooping. Foldable shafts that collapse for vertical storage prove especially useful in apartments or crowded garages. Rubberized support wheels further stabilize the tool when switched to edging mode, producing straighter sidewalk lines and reducing wrist strain.
Multi-Function Conversion and Accessories
True 2-in-1 or 3-in-1 designs that convert from string trimmer to wheeled edger or mini-mower in seconds eliminate the expense and storage of separate tools. Spacer guards protect plants and ornaments, while flower guards and additional grinding wheels expand utility for hardscape edges. Confirm that conversion requires only a simple button press or shaft rotation rather than tools. These features matter most for homeowners who maintain mixed lawn and garden spaces and want professional results without professional equipment.
Brand Ecosystem and Warranty Support
Brands with expansive battery-sharing platforms, such as WORX Power Share, allow one set of packs to power dozens of additional tools, lowering future investment. One-year warranties with responsive support, as noted on several value models, provide peace of mind for first-time buyers. Established names like BLACK+DECKER and Greenworks typically offer broader service networks. When evaluating, weigh the included accessories against the base price so the total package cost stays within the $39.99 – $119.99 bracket typical for this category. For more details on matching accessories to different lawn setups, explore the resources in the edgers category.
| Model | Cutting Diameter | Motor RPM | Weight | Key Battery Package |
|---|---|---|---|---|
| WORX WG163 | 12 inch | 7600 | 5.5 lbs | 2 x 20V batteries + charger |
| VARSK 12 Inch | 12 inch | 8700 | 5.3 lbs | 2 x 2.0Ah + charger + 6 spools |
| Greenworks 40V | 13 inch | Not Specified | Lightweight | 2.0Ah + charger (40-min runtime) |
This side-by-side comparison of three representative models highlights how motor speed and included spools influence daily efficiency, while battery packages determine total runtime. Use it as a starting point when narrowing choices within the $39.99 – $119.99 spectrum.
Testing & Selection Methodology
We compared 9 cordless string trimmer and edger models by first extracting every available technical specification from manufacturer data sheets, including motor RPM, cutting diameter, battery Ah rating, claimed runtime, weight, and conversion mechanisms. Next we cross-referenced user satisfaction indicators such as reported line-feed reliability and ease of head rotation, noting that ratings ranged from 4.4 to 4.9 where provided. Brand reliability was assessed through ecosystem size (number of compatible tools) and warranty length. Models lacking detailed feature lists were scored only on the concrete attributes supplied, ensuring no assumptions entered the ranking. Final selection weighted dual-function convenience and battery inclusion most heavily because those factors deliver the greatest day-to-day utility for typical residential yards.
Price-to-performance ratios were calculated using the listed retail figures against the number of batteries and spare spools included, confirming that value leaders stay near the lower end of $39.99 – $119.99 while still offering auto-feed systems. This systematic approach produces recommendations grounded in measurable data rather than marketing claims.
Best Picks & Final Verdict
After evaluating the full set of specifications, three models stand out for distinct buyer needs. The WORX Cordless String Trimmer & Lawn Edger WG163 earns the title of Best Overall String Trimmer And Edger thanks to its 2-in-1 conversion, command-feed spool, 90-degree tilting head, rubberized wheels, and dual 20V batteries all packaged at a mid-range price. Its 7600 RPM motor and free-spools-for-life program deliver consistent results across trimming and edging tasks while remaining part of a large battery-sharing family.
For shoppers seeking the Best Value / Budget Choice, the LPSUK 20V Cordless String Trimmer at the lower end of the price spectrum provides 3-in-1 trimmer-edger-mower functionality, an 8000 RPM motor, telescopic shaft, auto line feed, and eight spare lines, all while weighing only 5 lbs. This combination of features at an entry-level cost makes it ideal for small yards or first-time cordless buyers. Users focused on larger properties or denser growth will prefer the Greenworks 40V Cordless 2-in-1 Trimmer Edger as Best for Extended Runtime and Power, given its 13-inch cutting path and 40-minute runtime that outlasts typical 20V packs.
These recommendations cover the majority of residential scenarios within the current $39.99 – $119.99. Pair any selection with the adjustable accessories already included and consult the broader options listed in the edgers category if you need to expand into matching blowers or hedge trimmers later.
Frequently Asked Questions
What battery voltage is best for a string trimmer and edger?
A 20V system with dual 2.0Ah batteries suits most small and medium yards and delivers roughly 30 minutes of total runtime, while a 40V platform extends continuous cutting to 40 minutes and handles thicker weeds more effectively. Choose based on yard size and whether you already own compatible batteries from the same brand.
How do automatic line feed systems work on a string trimmer and edger?
Automatic or command-feed systems advance fresh line each time the trigger is released and re-engaged or when a dedicated button is pressed, eliminating the traditional bump-on-the-ground method that often causes jams. Most models also auto-cut excess line length against a fixed blade for consistent performance.
Can one tool really replace both a trimmer and a dedicated edger?
Yes, models designed with a 90-degree rotating head and support wheels convert from horizontal string trimming to vertical wheeled edging in seconds, producing clean sidewalk lines without a second machine. Look for units that include rubberized wheels and spacer guards for the cleanest results.
What weight should I look for in a cordless string trimmer and edger?
Target models under 5.5 lbs to reduce fatigue during 20- to 30-minute sessions. Lighter designs with telescopic shafts and pivoting heads further improve comfort for users of different heights and for working on slopes or under obstacles.
How often do I need to replace the string line?
Replacement frequency depends on grass density and how often the tool contacts hard surfaces, but models that include six or more spare spools or offer free replacement line programs keep ongoing costs low. Always keep a spare spool ready and inspect line condition after each use. Additional tips on maintenance appear throughout the edgers category pages.
