Weed Wacker Compatible with Dewalt 20V Max Battery, 12 Inch Cordless String Trimmer, Auto Line Feed Grass Trimmer w/9 Line Spools for Lawn, Yard and Garden (Battery Not Included)

What It Is

This is a 12-inch cordless string trimmer (weed wacker) that runs on a Dewalt 20V Max battery (sold separately). It’s designed for light to medium trimming tasks around lawns, gardens, and yard edges—not for heavy brush or thick weeds.

Fitment & Compatibility

• Battery required: Dewalt 20V Max battery (any Ah capacity). Battery not included.
• Deck/head size: 12-inch cutting swath. Fits standard trimmer line (0.065-inch or 0.080-inch recommended).
• Auto-feed system: Uses pre-cut line spools (9 included). Ensure spools are the correct width for the head (typically 0.065-inch line, 12-15 ft per spool).
• OEM vs aftermarket: This is an aftermarket trimmer, not a Dewalt OEM part. It will not replace a Dewalt trimmer head or spool—it’s a standalone tool.
• Check before buying: Confirm your Dewalt 20V Max battery has a working release tab and contacts. This trimmer uses the standard slide-on battery mount. Measure your yard size—this is not for large, overgrown areas.

Key Things to Know

• Quality & build: Mixed reviews (3.8/5). Some users report the auto-feed mechanism jams or the head cracks after a few uses. Plastic components feel less durable than Dewalt OEM trimmers.
• Installation/difficulty: Trivial—just slide on a charged battery and press the trigger. No assembly required beyond attaching the guard (included).
• Common gotchas: The auto-feed line can over-spool or snap if you hit hard objects. The 9 included spools are pre-wound but may not last long (expect 2-3 spools per full battery charge in light grass). Battery drain is moderate—a 5Ah battery lasts ~20-25 minutes of continuous use.
• No warranty details: As an aftermarket tool, check seller return policy. Dewalt does not cover this.

Should You Buy It

Buy this only if you already own Dewalt 20V Max batteries and need a cheap, lightweight trimmer for small, tidy-up jobs—like edging along sidewalks or trimming under shrubs. Skip it if you need a rugged, daily-use tool or plan to tackle thick weeds or large yards; invest in a Dewalt OEM trimmer or a gas model instead.
