Best Weed Eater Line for Electric and Cordless Trimmers
As an Amazon Associate we earn from qualifying purchases.
What’s the best weed eater line? It is the one that matches your trimmer’s spool, head and line diameter, because a line that is too thick or the wrong type will jam, wear the spool or refuse to feed. For most electric and cordless trimmers, the line comes as a pre-wound spool that snaps into the head, so the practical question is which replacement spool your model accepts and how many spools the pack includes. This guide compares six products from the product data: three replacement spools for specific trimmer families, and three cordless trimmers that include line in the box. It uses only the facts the listings state.
Quick answer
- For an EGO 56V 15-inch trimmer, the 4-pack AS1300 spool (B0H9C7QGWB) is the listing that names the EGO trimmer models and the AH1300 head. It is a 0.095-inch dual twist line.
- For a Ryobi One+ trimmer that takes the AC14RL3A spool, the KAKO 12+2 pack (B08DMJ52ZV) lists 11 feet of 0.065-inch nylon line per spool.
- For a Worx trimmer in the WG168, WG184, WG190 or WG191 family, the WETOOLPLUS 3+1 pack (B0BTTFMFSZ) names those models and includes one cap.
- If you own a cordless trimmer rather than a spool-fed one, check the bundled line count first. Three trimmers in this group include extra line, but none of them is a line-only product.
How to choose the right line
Start with the trimmer model number, not the line brand. A spool is a physical part with a fixed size and a fixed hub, and the listings in this group name compatible trimmer models for each spool. A spool made for a different platform may fit the eye and still not feed correctly, so a model match is the safest first step. If your model is not named, check the spool’s packaging or the manufacturer’s parts list before you buy.
Next, look at the line diameter. The listings in this group give three diameters: 0.095 inches for the EGO-compatible spool, 0.065 inches for the Ryobi-compatible spool, and 0.11 inches for the extra line that comes with one cordless trimmer. A thicker line cuts heavier weeds and tends to put more load on the motor, while a thinner line is lighter on the head. The trimmer’s manual sets the diameter it accepts, and the listing’s diameter should match that figure.
Then compare the pack size. The EGO listing is a 4-pack, the KAKO listing is 12 spools plus 2 caps, and the Worx listing is 3 spools plus 1 cap. The number of spools determines how often you will need to reload. A homeowner who trims a small yard once a week may need only one or two spools a season, while a person who mows an acre or uses a trimmer on a commercial schedule will go through spools much faster.
Last, check whether the line is pre-wound or bulk. Every spool in this group is pre-wound, which means you snap it in rather than wind line by hand. The listings describe tool-free or quick installation, and the EGO listing says the spool snaps in within about 3 seconds. That makes a pre-wound spool the practical choice for most people.
Comparison at a glance
The table uses only what the listings state. “Not stated” means the listing text does not say it. Where a spec field gives a figure that conflicts with the title or bullets, this guide uses the bullet or title figure and says so.
| Product (ASIN) | Type | Compatible with | Line or pack | Listed weight |
|---|---|---|---|---|
| EGO AS1300 4-pack spool (B0H9C7QGWB) | Replacement spool | EGO 56V 15-inch trimmers ST1500 family and AH1300 head | 0.095-inch dual twist, 4 spools | 11.7 ounces |
| KAKO AC14RL3A spool (B08DMJ52ZV) | Replacement spool | Ryobi One+ AC14RL3A spool; listed 18V, 24V models | 0.065-inch nylon, 11 ft per spool, 12 spools plus 2 caps | 4.16 ounces |
| WETOOLPLUS WA0014 spool (B0BTTFMFSZ) | Replacement spool | Worx WG168, WG184, WG190, WG191 | 3 spools plus 1 cap | 4.96 ounces |

Replacement spools, one by one
EGO AS1300 4-Pack Trimmer Spool, 0.095-Inch (B0H9C7QGWB)
This is the spool with the most specific model match in the group. The title and bullets say it is made for EGO POWER+ 56V 15-inch string trimmers. The listing names the trimmer models ST1500, ST1500-S, ST1500F, ST1500SF, ST1504SF, ST1500XY, ST1502XY and ST1502SA, and it names the trimmer head AH1300. If your EGO trimmer is in that family, this spool is the listing that states the match directly.
The line is described as a 0.095-inch diameter, heavy-duty polyamide nylon cord on an impact-resistant ABS spool. The listing calls it a dual twist line with a spiral design, which it says reduces air resistance and noise during high-speed rotation. The bullets say the line is flexible, abrasion-resistant and suited to thick weeds, tall grass, and edges along sidewalks and patio joints. Those are the listing’s own descriptions. They are not results from a trial, and this guide does not claim to have run the line.
The pack is a 4-pack, and the listing describes a tool-free quick-wrap system that snaps the old spool out and the new spool in. The listed item weight is 11.7 ounces. The brand field is blank and the listing’s manufacturer is LCJZSET. Because the spool is pre-wound and the pack includes four, this is a practical choice for an EGO owner who wants a full season of reloads on hand.
KAKO AC14RL3A Replacement Spool for Ryobi Weed Wacker, 0.065-Inch, 12 Plus 2 Pack (B08DMJ52ZV)
This spool is made for the Ryobi One+ AC14RL3A spool format. The title and bullets describe it as an 11-foot, 0.065-inch diameter nylon line pre-wound on an ABS spool. The bullets name a list of Ryobi trimmer models, including 18V models such as OLT1825, OLT1830H, OLT1831 and RLT1830H15, and a 24V model, RY24000. The listing says the spool works with an automatic line change, and it describes the cut as coming from CNC machining and winding.
The title says the pack is 12 spools plus 2 caps, and the bullets repeat that count. The listing gives a weight of 4.16 ounces. Some listing fields show different pack counts, such as 14 packs and 500 items, which look like data errors, so this guide relies on the title and bullet count of 12 spools plus 2 caps.
Because this is a 0.065-inch line, it is a lighter choice than the EGO spool. That matches the listing’s emphasis on Ryobi trimmers, which are usually built around thinner line. If your Ryobi trimmer uses a different spool, the model list is the thing to check before you buy, since the listing is specific about the AC14RL3A format.
WETOOLPLUS WA0014 Spool Line and Cap Cover for Worx, 3 Plus 1 Pack (B0BTTFMFSZ)
This pack includes three spools and one cap cover, and the title says the cover is a 3+1 set. The listing says the spools are a direct replacement for the original WA0014 part and that the cap is designed to match the original. It names WORX models WG168, WG184, WG190 and WG191, and it says the spools are made from copolymer nylon resin. The bullets describe an anti-tangle, no-jam design and a sturdy cap that holds the spool in place.
The listing’s spec fields show a weight of 4.96 ounces and list a cutting width of 0.08 inches. The listing does not state the line diameter in its bullets, so a buyer should confirm the diameter against the trimmer’s manual before loading the spool. The brand is WETOOLPLUS, and the item type is string trimmer spool.
This pack suits a Worx owner who needs spools plus a spare cap. The three-spool count is a good size for a yard that is trimmed a few times a month, and the cap is useful if the original cap is lost or cracked. The listing offers a satisfaction guarantee, but the terms of that guarantee are on the seller’s page and this guide does not restate them.
Cordless trimmers that include extra line
Three cordless trimmers in the product set include line. These are complete tools, not spool packs, and they are shown here because the line is a real part of the box. If you already own a trimmer and want only line, one of the spool products above is the better fit. If you are buying a trimmer and want a spare line supply at the same time, the three below are worth a look.
MtiolHig Cordless String Trimmer for Milwaukee 18V, with 18 Extra Lines (B0DSPTVJFB)
The listing is for a 3-in-1 trimmer, edger and mower head that works with Milwaukee 18V batteries. The battery and charger are not included, and the listing says so in its first bullet. The bullets say the package includes 18 extra 0.11-inch lines, which is the largest line supply in this group. The listing states a cutting width of 11 inches and a no-load speed of 8500 RPM in the bullet text, while one specification field shows 4800 rpm, so the bullet figure is the one this guide uses.
The listing says the shaft telescopes from 50 to 60 inches and the head tilts 75 degrees, and it describes a folding design that drops to 28 inches for storage. The bullet gives a weight of 5.5 pounds, while a spec field gives 6 pounds. The guard is adjustable, and the listing names the guard as a feature for protecting flowers and shrubs. Because the trimmer is tool only, budget for a Milwaukee 18V battery and charger if you do not already own them.
Lacoco Cordless String Trimmer and Edger for Dewalt 20V, with 8-Piece Spool Line (B0H8MT97HR)
This is a 14-inch 3-in-1 cordless tool that the title says is made for Dewalt 20V batteries, with the battery not included. The title also names an 8-piece grass cutter spool line. The bullets say the tool converts between a string trimmer, a wheeled edger and a mini mower, and that it has a 180-degree adjustable handle and a 60-degree adjustable cutting head. The listing gives a speed of 20000 RPM and a 750W motor, and the specification fields show a weight of 5 pounds.
The bullets do not describe the line diameter, so the diameter is not stated. If you buy this tool, confirm the line size in the box before you trim. The brand is Lacoco and the model number is GCJ-06B. The listing’s claims about the 20000 RPM speed and the wheeled design are the listing’s own statements.
Lemolifys 20000 RPM Brushless Cordless String Trimmer for Dewalt 20V, with 8 Line Spools (B0HJC217DF)
This 3-in-1 trimmer is made for Dewalt 20V MAX batteries, and the listing says the battery and charger are not included. The title says the package includes 8 line spools. The bullets describe a 14-inch cutting path, a detachable wheel set that converts the tool between a wheeled lawn edger and a handheld weed eater, and a weight of about 4 pounds. The listing says the tool is light enough for seniors and women to handle, which is a claim about handling in the listing text.
The line diameter is not stated in the bullets, and the specification fields give only the brand, color, unit count and model number XB-DCS-GCJ. Check the spool packaging when the tool arrives. If you already own a Dewalt 20V battery, this is a tool that works with it. If you do not, the battery cost is part of the purchase.
Mistakes to avoid when you buy line
- Matching brand instead of model. A spool made for one platform will not always fit another. Check the model list in the listing before you buy.
- Ignoring the diameter. The listings use 0.065, 0.095 and 0.11 inches. The trimmer’s manual sets the diameter it accepts, so use that figure as the test of compatibility.
- Buying a tool for the line. A cordless trimmer that includes line is still a tool purchase. Do not pick a tool only because it includes spools if you already own a compatible trimmer.
- Relying on odd spec fields. Several listings show pack counts or dimensions that conflict with the title, such as 14 packs for a 12-spool bundle. Use the title and bullets for the count.
- Forgetting the battery. All three cordless trimmers are sold tool only, with no battery or charger in the box. Add the battery and charger to the budget before you buy.
How to decide in five minutes
Look up your trimmer’s model number and its spool or head name. If the model is EGO 56V 15-inch, the EGO AS1300 spool is the listing that names the match. If the model takes the Ryobi AC14RL3A spool, the KAKO pack is the one that lists those models. If your trimmer is a Worx WG168, WG184, WG190 or WG191, the WETOOLPLUS pack names those models. If you are shopping for a new cordless trimmer, count the extra line in the box, then check the battery platform you already own.
FAQ
What is the best weed eater line for most trimmers?
There is no single best line for every trimmer. The best line is the one your trimmer’s head accepts, in the diameter its manual specifies. In this group, the listings name specific fits for EGO, Ryobi and Worx spools. Start with the model, then the diameter, then the pack size.
Does thicker line always cut better?
The listings do not make that claim for every product. The EGO spool’s listing says its 0.095-inch dual twist line is designed for thick weeds, tall grass and rugged yard conditions. The Ryobi spool is 0.065 inches. A thicker line is not automatically better; use the diameter the trimmer is built for.
Are pre-wound spools easier than bulk line?
Every spool in this group is pre-wound, and the listings describe quick installation. The EGO listing says the spool snaps in within about 3 seconds using a tool-free system. Pre-wound spools avoid the hand winding that bulk line needs, so they are the practical choice for most homeowners.
How many spools should I buy?
The packs in this group contain 3, 4 or 12 spools. A household that trims once a week will need fewer than a household that trims more often. Buy a pack that covers the season, and keep one spare on hand so a broken spool does not stop the work.
Do the cordless trimmers include a battery?
None of the three cordless trimmers in this group includes a battery or charger. Each listing says the tool is sold as a bare tool, and the battery platform is Milwaukee 18V for one, and Dewalt 20V or 20V MAX for the other two.
Can I use one brand’s spool on another brand’s trimmer?
The listings name specific compatibilities, and they do not say that a spool from one brand will fit another. Use the model match in each listing, and if your trimmer is not named, check the parts list from the trimmer’s manufacturer before buying.
Bottom line
The best weed eater line is the one that matches your trimmer model and head. For an EGO 15-inch trimmer, the EGO AS1300 4-pack is the listing with the direct match. For a Ryobi AC14RL3A spool, the KAKO 12-plus-2 pack covers a long season. For Worx WG168, WG184, WG190 or WG191 trimmers, the WETOOLPLUS 3-plus-1 pack names those models. If you are buying a new cordless trimmer, count the extra line in the box and check the battery you already own, because none of the three includes one.
