Cordless String Trimmers Compared: 7 Listings
As an Amazon Associate we earn from qualifying purchases. Details
The search behind this page named Greenworks string trimmers, but the listings it returned include only one Greenworks trimmer. This page therefore compares seven cordless string trimmers and trimmer combos, with the title written around that product type. Three are bare tools with no battery, and four include batteries, one of them a combo with a mower deck. Listing figures were checked between 11 and 12 October 2026, and they are shown as each seller states them.
Quick answer
If you want a battery and charger in the box, the Greenworks 24V, the RAXONE 21V and the JAGROM 20V all list batteries and a charger as included. If you want the longest stated run time, the RYOBI 40V listing gives 71 minutes on a 4Ah battery, but that listing is a bare tool. If you want one tool that also cuts a small lawn, the BLACK+DECKER MTC220 combo is the only listing here with a removable wheeled mower deck.

How we chose these listings
A string trimmer is the product type used here. Seven of the twelve products came up as trimmers or trimmer combos. The other five were excluded: three paper cutters (B075NYWF5P, B08PKXC1B7 and B0DG4DJSRV), a 12V AC adapter for a WORKPRO grass shear (B0DCF89S75), and a 22V AC/DC adapter for a hedge trimmer (B0CS66QPRT). None of them is a string trimmer, so none is compared here. Each trimmer appears once, and the figures come from the bullets and specification fields. Where a title and a specification field disagree, both values are shown.
1. Greenworks 24V 12 in String Trimmer (B0G6D3HDYF)
This is the only Greenworks trimmer in the set. The bullets describe a brushless motor, a 12-inch cutting path with a 0.065-inch dual line, and a 2-in-1 design that converts from trimmer to edger. The telescoping aluminum shaft is listed as adjustable from 4 feet 8 inches to 6 feet 5 inches. The kit includes a 3.0 Ah battery, a 65W Type-C charger, a 3-foot charging cable and 10 plastic blades. The model is ST1212, and the item dimensions are 52.95 inches long by 12.4 inches wide. The specification field lists the item weight as 5 g, which does not fit the rest of the listing, so check the weight on the product page.

2. RYOBI 40V 15 in String Trimmer, Bare Tool (B0D23XZKZL)
The title says this is a bare tool, and the battery field says one battery is required. The bullets say up to 71 minutes of runtime with a 40V 4Ah battery, and the battery average life field also gives 71 minutes. The bullets say it accepts the EXPAND-IT attachments, and they include a claim that it has more power than a 21cc gas trimmer. The title gives a 15-inch cutting width, while the specification field gives 13 inches, so the two figures need to be checked on the product page. The listed speed is 8,500 rpm, the item weighs 11 pounds, and the warranty is a 30-day limited warranty.

3. BLACK+DECKER MTC220 Weed Eater, Edger and Mower Combo (B00HH4K548)
This combo is the only listing here that is a trimmer, an edger and a mower in one. The bullets describe a removable wheeled deck that turns the unit into a small push mower, and an automatic feed spool that the listing says keeps the trimmer running without line adjustments. The kit includes two lithium-ion batteries and a charger, and the specification fields give a 12-inch cutting width, a 20V type and an item weight of 9.9 pounds. The listed dimensions are 40.5 inches long by 15.25 inches wide. The included items name the string trimmer, a guard, an auxiliary handle and a spool. The warranty is a 2-year limited warranty.

4. Lacoco 14 in Cordless Trimmer for Dewalt 20V, No Battery (B0H8MT97HR)
This listing is a tool only, and the title says no battery is included. The bullets say it works with Dewalt 18V to 21V packs and name several Dewalt model numbers. The cutting width is 14 inches, the widest in this group, and the specification field lists a speed of 20,000 rpm. A bullet gives a 750W motor, and the listing does not say how that figure was measured. The item weighs 5 pounds, and the title says the kit includes 8 spool lines. The specification field names the brand as Lacoco and the model as GCJ-06B. No warranty term appears in the fields read.

5. RAXONE 21V Cordless Trimmer and Edger (B0HFJCZDT6)
This trimmer includes two 2.5 Ah batteries and a fast charger, so it is ready to use from the box. The bullets give a speed of 9,500 rpm and a 12-inch cutting path, and they describe an automatic line feed that releases line during use. The specification fields list an item weight of 6.2 pounds, a model of HG0556-CRE and a crimson color. The listing dimensions are 49.21 inches long by 12 inches wide. No warranty term appears in the fields read, and the listing does not name a compatible battery brand.

6. JAGROM 20V Electric String Trimmer and Edger (B0DTPB4Y2Z)
The title says 2.0Ah battery and charger, while the specification field says two lithium-ion batteries are included. This is one of the points to check on the product page before you buy. The bullets describe a 2-in-1 trimmer and edger with a wheel, a shaft that folds 180 degrees in three directions, and a head that adjusts 90 degrees. The listed speed is 9,500 rpm and the cutting width is 12 inches. The specification field gives an average battery life of 30 minutes, and the item weighs 7 pounds. The model is listed as jag, and the dimensions are 40 inches long by 14 inches wide.

7. Bamse 21V String Trimmer Body (B0GG8Q4WC1)
This is a bare body. The title and the included items field both say the battery and charger are not included. The color is red, the brand is Bamse, and the model is MR7503. The listing does not give a cutting width, a speed, a weight or a warranty in the fields read, and the bullets consist of the title only. Buy this only if you already own a 21V battery that the listing’s title describes, and confirm compatibility on the product page, because the listing does not name a battery brand.

Worked example: run time and cutting path from the listed numbers
Run time is the first figure to compare. The RYOBI listing gives 71 minutes on its 40V 4Ah battery. The JAGROM specification field gives an average battery life of 30 minutes. For a 20-minute session, the RYOBI battery covers three full sessions with about 11 minutes left, while the JAGROM battery covers one full session with 10 minutes left. These are averages from the listings, not measured runs, and the listed run time depends on the load and the grass.
Cutting path is the second figure. The Lacoco listing gives 14 inches and the Greenworks, RAXONE, JAGROM and BLACK+DECKER listings give 12 inches. A 14-inch pass is 2 inches wider than a 12-inch pass, or about 17 percent more width per pass. A strip that takes 12 passes with a 12-inch trimmer takes about 10 passes with a 14-inch one (12 divided by 1.17 is about 10.3), if the passes overlap the same way. The RYOBI listing gives 15 inches in the title and 13 inches in the specification field, so its width is the one figure in this group that needs checking.
What we could not verify
The listings do not give cutting speed, line diameter or noise in a comparable form, so this page cannot rank the trimmers on those points. Warranty terms are missing from five listings. The Greenworks weight and the RYOBI cutting width conflict with other fields, and the JAGROM battery count conflicts with its title. Only five of the seven listings give item dimensions, and each gives length and width without a height, so a storage check needs the product page. The Lacoco and Bamse listings give no dimensions in the fields read. The Lacoco 750W figure is a bullet claim, and this page does not confirm it. The bare tools in this group need a separate battery, and the listings do not say which battery pack is included or needed beyond the fields quoted above.
Frequently asked questions
Which of these trimmers include a battery and charger?
The Greenworks 24V, the BLACK+DECKER MTC220, the RAXONE 21V and the JAGROM 20V include batteries, and each lists a charger. The RYOBI 40V and the Lacoco and Bamse listings are bare tools, so you will need a battery and charger for them.
Which trimmer has the longest stated run time?
The RYOBI listing states up to 71 minutes on a 40V 4Ah battery. The JAGROM specification field states an average battery life of 30 minutes. The other listings do not give a run time in the fields read.
Does the Lacoco trimmer work with a Dewalt battery?
The Lacoco bullets say it is compatible with Dewalt 18V to 21V batteries and name several Dewalt model numbers. Check the battery model on the product page before you buy, because the listing is a bare tool and does not include a battery.
Which of these can also cut a lawn?
The BLACK+DECKER MTC220 is the only listing here with a removable wheeled deck that turns the unit into a small push mower. The other six are trimmers or trimmer and edger tools with no mower deck listed.
Is the Greenworks trimmer a trimmer and an edger?
Yes. The Greenworks bullets describe a 2-in-1 design that converts from trimmer to edger. The JAGROM listing also describes a 2-in-1 trimmer and edger, and the RAXONE title describes a trimmer and edger.
Conclusion
For a ready-to-use trimmer with the batteries in the box, the Greenworks, RAXONE and JAGROM listings are the simplest choices, with the JAGROM title and specification conflict to check first. For the longest stated run time, the RYOBI bare tool is the figure to compare, once you have a battery. For a trimmer and a small mower in one unit, the BLACK+DECKER MTC220 is the only combo here. Check the battery and charger fields and the warranty on each product page before you buy. The figures on this page are a snapshot from 11 to 12 October 2026, so confirm each one on the live listing.
