Weed Eaters That Run on DeWalt 20V Batteries

Best for
Small yards needing trimmer and blower

The Houselife Cordless Weed Eater and Leaf Blower Combo is a two-tool bare kit designed for DeWalt 20V MAX XR lithium-ion batteries. You get a 4.2-pound 12-inch string trimmer and a 3-pound handheld blower. The combo weighs 7.2 pounds in total.

The trimmer converts between trimmer, in-line wheeled edger and mini mower using a 180-degree adjustable handle and a 90-degree tilting head. It runs at 8500 RPM with auto-feed line, has dual safety locks and a flower guard. The blower claims 400 CFM and 130 MPH with a slim nozzle and one-button control. The spec block lists a battery average life of 30 minutes, though it does not say which battery size that assumes.

This suits owners of small yards who want both jobs covered with batteries they already have. If you do not need a blower, the standalone Houselife trimmer below is the same trimmer concept on its own. If you already run DeWalt gear in the garage, a DeWalt battery powered vacuum is another way to clean up with the same packs.

• 12-inch trimmer plus 400 CFM blower
• Trimmer, edger and mini mower modes
• 8500 RPM with auto-feed line

Light trimming and edging on a budget platform

The Houselife Cordless Weed Wacker Compatible with DeWalt 20V MAX is the trimmer-only version from the same brand. It weighs 4.2 pounds, cuts a 12-inch swath and uses a copper wire motor at 8500 RPM no-load speed.

The dual-mode line system uses an auto-feed centrifugal design that releases 0.4 inch of line each start, plus a second manual option. The 180-degree auxiliary handle and 90-degree tilting head switch it between string trimmer, wheeled edger and mini mower. Dual safety locks and a guard shield round it out, and the listing gives a 1-year warranty.

It suits homeowners doing light, regular trimming around a small lawn and flower beds. It gives way to the brush-cutter style tools when weeds are thick and woody.

• 4.2 pounds, 12-inch cut
• Auto-feed plus manual line advance
• 1-year warranty

The LARYICTU Cordless Weed Wacker for DeWalt 20V is the brushless weed eater for DeWalt battery owners who face tougher growth. The listing claims a 960W brushless motor with idle speeds up to 21,000 RPM, and lists DCB200, DCB203, DCB204, DCB205, DCB206, DCB208, DCB210 and DCBP034 batteries as compatible.

It ships with four blades: a 10.6-inch white plastic blade for lawn edges, an 8.7-inch red plastic blade for soft grass, a 7.5-inch metal blade for older weeds and reeds, and a 7-inch alloy saw blade. A telescopic bar adjusts from 40 to 56 inches, the head tilts 90 degrees up and down and rotates 90 degrees left and right, and auxiliary wheels help on long edges. It weighs 6.4 pounds and has dual on/off switches and an anti-collision bar.

Treat the wattage and speed as seller claims, since they sit far above the other trimmers here. Always wear eye and leg protection with metal blades. This suits yards with overgrown patches; for neat lawn edging, a line trimmer is gentler.

• Brushless motor, up to 21,000 RPM claimed
• Four blade types including metal and saw
• Telescopic 40-56 inch bar and wheels

Weekly edging on sidewalks and driveways

The GELIDALITE 12-Inch Cordless String Trimmer for DeWalt 20V is the most detailed listing for everyday lawn care. It names DCB200, DCB203, DCB204, DCB205, DCB206 and DCB240 batteries, uses a 200W copper motor at 9000 RPM and cuts a 12-inch swath.

It is a 3-in-1 trimmer, wheeled edger and mini mower with quick-attach guide wheels that carry the tool’s weight along sidewalks. The auto-feed spool releases 0.4 inch of line per start, it includes six pre-wound spools of 16.5 feet each and it accepts standard 0.065-inch line. GELIDALITE estimates about 30 minutes of trimming on a 4.0Ah battery and about 45 minutes on a 6.0Ah battery. It weighs 4 pounds with a steel shaft.

The seller offers a 90-day return window and a 1-year replacement promise, as part of what it calls a 4-tier guarantee. This is the pick for weekly maintenance on yards up to about half an acre. For thick brush, look at the LARYICTU instead.

• 200W motor, 9000 RPM, 12-inch swath
• Guide wheels for edging
• Six 0.065-inch spools included

Controlled line feed for tidy edges

The HEINPRO Cordless String Trimmer Compatible with DeWalt 20V MAX is a 4.2-pound 12-inch trimmer that turns into a wheeled edger by rotating the head 90 degrees. Its line system releases about 0.5 inch automatically each time you pull the trigger, and a button on the head lets you pull out line manually if it breaks.

A 180-degree rotating handle and 5-position cutting angle help fit it to your height and terrain. It has dual safety switches and a spacer guard to protect plants, and includes six 0.055-inch spools of 16.5 feet each. The listing describes a strong motor but does not specify wattage or RPM. Its model number and dimensions closely resemble the second Houselife trimmer, though the listings do not say whether they share a design.

Pick the HEINPRO if you want more control over line length when edging borders. For listed runtime estimates, the GELIDALITE gives more detail.

The Bavpelp 4 in 1 Cordless Weed Wacker for DeWalt 20V lists the widest battery range, including DCB200, DCB201, DCB203, DCB204, DCB205, DCB206, DCB230, DCB240, DCB246, DCB248 and DCBP520. It includes four cutting options: trimmer line for soft lawns, stainless steel blades for older weeds, alloy saw blades for branches and a grass brush for moss.

The shaft adjusts from 37 to 53 inches and the head angle adjusts. Here the listing gets shaky. It claims a 13000W brushless motor, which is not a realistic figure for a 20V tool; the spec block gives a cutting width of 12 centimeters while the title says 12 inches; and it lists a weight of 4.3 pounds in the features but 1 kg in the specs. Read those numbers skeptically.

It suits someone who wants many attachments in one tool for mixed jobs. If you value clear, consistent specs, the GELIDALITE or LARYICTU listings are more coherent.
