Best Cordless Lawn Edgers and String Trimmers Compared
As an Amazon Associate we earn from qualifying purchases.
This page compares three cordless tools whose listings describe lawn edging: a dedicated goodjob edger with batteries included, a Bosch 18V trimmer and edger combo sold as a bare tool, and a Craftsman V20 two-in-one sold as a tool only. Every figure comes from the listing text and spec fields checked on 2026-10-18. Nothing here comes from using the tools, and the page does not rank them by performance. It shows what each listing states, where the listings disagree, and which details to confirm before you order. Read the table for a quick side-by-side, then the product cards for the detail.
Quick answer: which one fits which job
If you want a dedicated edger with a battery and charger in the box, the goodjob listing is the only one of the three that states both. If you already own a Bosch 18V or AMPShare battery, the Bosch combo is the match, and the Craftsman fits a V20 owner. Both combos describe edging as a mode of a trimmer, so they suit people who also trim fence lines.

Product by product
1. goodjob Cordless Lawn Edger, 20V
The listing states two 2.0Ah 20V lithium batteries and a fast charger come in the box, with 40 minutes of total runtime and a 50 minute quick charge (checked 2026-10-18). The bullets give a 400 watts motor at 3,500 RPM and a lock-tight 9 inch steel blade with a full blade shield. Edge depth has three settings at 1.25 inches, 1.5 inches and 1.75 inches, and the rear dual guide wheels, listed at 4 inches, ride against the edge.
The spec table gives a weight of 4.5 pounds, dimensions of 9 x 7 x 24 inches, and model GB-DLE22A-2MG. The listing also mentions a 180 degree rotatable auxiliary handle, tool-free assembly, a double safety trigger lock, and a 1-year limited warranty.
The battery spec field reads 2 A batteries required (included), which gives no voltage or capacity. The bullets name 20V packs rated 2.0Ah, so confirm the pack rating with the seller before you order.
Best for: a homeowner who wants a dedicated edger with batteries and a charger in one box.
Skip if: you want to reuse a battery you already own, because the listing does not say whether its packs work with other tools.
2. Bosch GRT18V-40N 18V Brushless 16-Inch String Trimmer and Lawn Edger Combo
The listing states this is a bare tool, so no battery or charger comes in the box. It says 18V batteries and chargers work with Bosch 18V tools and products from other AMPShare brands. The motor is brushless with a maximum speed of 5,300 RPM, the cutting swath is 16 inches wide, and a Pro-Tap spool with EasyWind handles line advancement. A toolless adjustable D-handle and a dual-function hand grip are described as the way to switch from trimming to edging.
The spec table gives a weight of 12.7 pounds, a five year limited warranty, and model GRT18V-40N. It lists the item type as String Trimmers, while the title and bullets describe a combo with an edging function.
The Size field reads 757 in, which does not match the 16 inches cutting width in the same listing. The listing does not describe an edge guide or wheel and gives no edge depth setting, so its edging result cannot be set against the goodjob.
Best for: a landscaper or homeowner who already owns Bosch 18V or AMPShare batteries and wants one head for trimming and edging.
Skip if: you need a light tool or a battery in the box, since the listing gives 12.7 pounds and sells the tool bare.
3. Craftsman V20 2 in 1 String Trimmer and Lawn Edger, CMCST901B
The listing states this is a tool-only unit for the V20 battery platform. It gives up to 63 minutes of trimming on a single charge, and the spec table repeats 63 minutes as average battery life. The bullets claim a motor that delivers 52% more power, a 13 inches cutting path, and two speed settings that trade runtime for power.
Edging uses a Turn-To-Edge feature, and the handle height is adjustable. The warranty is 3 years limited. The spec table gives dimensions of 31.77 by 7.72 inches and the colors black and red, but it gives no weight.
The listing marks the 63 minute figure with an asterisk and the 52% figure with a double asterisk, but the footnotes are not in the data, so the test conditions are unknown. The title calls it a 2 in 1 with a lawn edger, while the item type field reads String Trimmer.
Best for: a V20 owner who wants one tool that trims and edges and already has a V20 battery.
Skip if: you need the weight before you buy, or you do not own a V20 battery, because the listing sells the tool without one.
How the three were chosen
Each product is a cordless tool whose listing describes an edging function, checked on 2026-10-18. Replacement string spools and pole saw attachments do not match a cordless edger search, so they are not included. Only three listings met that test, so this is a short comparison rather than a full roundup. Where the listings conflict, the conflict sits next to the figure it affects.
Weight and runtime from the listings
The two figures the listings state most directly are weight and runtime. The goodjob weighs 4.5 pounds and the Bosch weighs 12.7 pounds, so the difference is 8.2 pounds. The goodjob states 40 minutes of total runtime across two 2.0Ah packs, which is 20 minutes per pack if the two packs share the work evenly. The Craftsman states up to 63 minutes on a single charge, which is 23 minutes more than the goodjob total.
The comparison is not like for like. The goodjob figure is a total for two packs, the Craftsman figure is for one charge, and neither listing gives test conditions. Read both as manufacturer claims, and check the battery count before you compare them.
What the listings do not say
- None of the three listings gives a measured result for edge quality, speed or line life. The text is manufacturer wording.
- The Craftsman listing gives no weight, and the Bosch listing gives no runtime figure.
- The Bosch and Craftsman listings do not state an edge depth, so their edging depth cannot be set against the goodjob settings of 1.25 inches, 1.5 inches and 1.75 inches.
- The goodjob battery field reads 2 A batteries required, which conflicts with the 2.0Ah 20V packs named in its bullets.
- The Bosch Size field reads 757 in, which conflicts with its 16 inches cutting width.
- The Craftsman footnotes for the 63 minute and 52% figures are missing from the data, so those figures have no stated conditions.
Frequently asked questions
Is a dedicated edger better than a two-in-one for edging?
The goodjob is the only listing here that describes a dedicated edger, with depth settings and guide wheels. The Bosch and Craftsman listings describe edging as a mode of a trimmer, so their listings do not show how their edges compare with the goodjob.
Which of these come with a battery?
Only the goodjob lists batteries and a charger as included, with two 2.0Ah 20V packs. The Bosch is a bare tool and the Craftsman is tool only, so each needs a compatible battery and charger bought separately.
Which runtime figure should I trust most?
None of them is a like for like figure. The goodjob states 40 minutes total across two packs, the Craftsman states up to 63 minutes on a single charge, and the Bosch states no runtime at all. Ask the seller for test conditions if runtime decides your purchase.
Is the Bosch too heavy for edging?
The listing states 12.7 pounds, which is 8.2 pounds more than the goodjob’s 4.5 pounds. Whether that matters depends on how long you work and how you hold the tool, and the listing does not address either.
Will a Bosch battery run the goodjob or the Craftsman?
The listings do not say so. The Bosch listing names 18V batteries compatible with Bosch and other AMPShare brands, the goodjob names its own 20V packs, and the Craftsman names the V20 platform. Check the battery platform before you buy any of them.
Conclusion
For a dedicated edger with batteries in the box, the goodjob listing is the only one of the three that states both. For a trimmer that also edges, the Bosch suits an existing 18V Bosch or AMPShare battery owner, and the Craftsman suits a V20 owner. Before you order, confirm the battery count and voltage for the goodjob, the runtime conditions for the Craftsman, and the size field for the Bosch.
