3 in 1 Cordless String Trimmer (No Battery) Compatible with Dewalt 20V Max Battery, 12" Electric Weed Wacker with Auto Line Feed, Foldable Weed Eater/Edger Trimmer/Mower for Yard Garden, Grass Trimmer

What It Is

This is a 12-inch cordless string trimmer that runs on a Dewalt 20V Max battery (sold separately). It functions as a trimmer, edger, and mini mower for small yards, gardens, or touch-up work around flower beds and fences.

Fitment & Compatibility

• Battery: Requires any Dewalt 20V Max battery (XR or standard). Does not include a battery or charger.
• Cutting width: 12 inches – suitable for light trimming, not heavy brush or tall weeds.
• Head type: Bump-feed auto line advance; uses 0.065-inch or 0.080-inch trimmer line (check manual for exact spec).
• Edger mode: Rotates head 90°; works with standard sidewalk/curb edges.
• Foldable shaft: Collapses for storage, but check that the locking mechanism is secure before each use.

Before buying: Verify you already own a Dewalt 20V battery and charger. If not, budget an extra $40–$80 for a battery kit. Measure your yard size – this trimmer is best for lots under ¼ acre.

Key Things to Know

• Battery not included – a common gotcha. Many buyers miss this and can’t use it immediately.
• Auto line feed can be finicky – some users report the bump head jams or skips; you may need to manually pull line occasionally.
• Build quality is mixed – the shaft is plastic, and the head can crack if you hit rocks or curbs repeatedly.
• Lightweight but underpowered – fine for grass and light weeds, but struggles with thick brush or overgrown areas.

Should You Buy It

Buy this if you already own Dewalt 20V tools and need a compact trimmer for small, light-duty trimming and edging. Skip it if you have a large yard, heavy weeds, or need a battery included – you’ll be better served by a gas trimmer or a higher-end cordless model with a battery kit.
