Weed Wackers That Run on Your DeWalt 20V Batteries

As Amazon Associates, we earn from qualifying purchases. This means we may receive a small commission at no extra cost to you if you click through and make a purchase.

If you already own DeWalt 20V MAX batteries from a drill or impact driver, it makes sense to look for a weed wacker (also called a string trimmer or weed eater) that can use them. An important point up front: all six trimmers in this guide are third-party tools made by other companies, such as Houselife, OJFAON, HEINPRO, worksky and GELIDALITE, and designed to fit DeWalt 20V batteries. They are not made or sold by DeWalt, and none of them includes a battery or charger.

These six differ mainly in cutting width, whether they convert into an edger or mini mower, and whether they use string, blades or come bundled with a leaf blower.

Cordless Weed Wacker for DeWalt 20V

Best for: Weeds between pavers and light brush

Pros

  • 4 interchangeable blade types
  • Telescopic 36-52 inch pole
  • Gloves and eye mask included

Cons

  • 8-inch cutting width
  • Listing weight conflicts: 4.5 vs 7 lbs
Cordless Weed Wacker Compatible with DEWALT
Cordless Weed Wacker Compatible with DEWALT

Best for: Small yards needing trim, edge and mow

Pros

  • 3-in-1 trimmer, edger, mini mower
  • Light 4.2 lbs
  • Auto and manual line feed
  • 90° tilting head

Cons

  • Third-party tool, not DeWalt-made
  • 12-inch cutting width

The Cordless Weed Wacker Compatible with DEWALT batteries is made by Houselife (model HL-DST30A-0DB) and sold as a bare tool, meaning you get the trimmer only. It works as three tools in one: a string trimmer, an in-line wheeled edger for crisp lines along sidewalks, and a mini lawn mower for small patches of grass. It has a 12-inch cutting diameter and a flower guard to keep the line away from plants.

The motor has a listed no-load speed of 8,500 RPM. No-load speed is how fast the head spins with nothing slowing it down, so real-world speed in thick grass will be lower. The line feed works two ways: an auto feed releases 0.4 inches of line every time you start the tool, and there is also a manual option. At 4.2 lbs, it is among the lighter options here, with a 180° adjustable auxiliary handle, a 90° tilting head, a dual safety lock and a one-year manufacturer warranty.

This suits a homeowner with a small yard who wants one light tool for trimming, edging and quick mowing. If your lawn has long borders or thick weeds, the wider 16-inch HEINPRO model covers more ground per pass.

Cordless Weed Wacker for DeWalt 20V for Weeds and Light Brush

The Cordless Weed Wacker for DeWalt 20V packs, sold by OJFAON, works differently from a classic string trimmer. It comes with interchangeable heads: two circular saw blades, two stainless steel blades, a grass rope and a grass brush. The listing describes the brush for removing weeds and moss from paving, and the steel blades for small shrubs and older weeds. It lists compatibility with a long list of DeWalt 20V MAX batteries, including the DCB200, DCB203, DCB205 and DCB240.

A telescopic pole adjusts from 36 to 52 inches, which helps both shorter and taller users stand upright. It has dual safety starter switches and a splash guard, and the kit adds gloves, an eye mask and a tool kit. The cutting width is listed at 8 inches, the narrowest here. The listing gives two weights, 4.5 pounds in the features and 7 pounds in the specifications, and does not explain which applies.

This is a useful tool for patios, paths and garden beds with stubborn weeds. It is not the best pick for trimming large lawn edges; one of the 12-inch or 16-inch string trimmers will be quicker there.

HEINPRO Cordless Weed Wacker Compatible for Wider Cuts and Brushless Power

HEINPRO Cordless Weed Wacker Compatible

Best for: Bigger lawns wanting wider cuts

Pros

  • Brushless motor
  • 16-inch cutting swath
  • Bump feed line
  • Extra 0.08-inch line coils

Cons

  • Heavier at 5.8 lbs
  • No edger or mower mode listed

The HEINPRO Cordless Weed Wacker Compatible with DeWalt 20V MAX batteries (model HP-DST39A-0DB) is the only brushless model here. A brushless motor skips the small carbon brushes found in older motors, which the listing says improves efficiency, reduces heat and lengthens service life. It has a 16-inch cutting swath, the widest in this guide, and a listed speed of 6,000 RPM.

Line advances by bump feed, which means you tap the head on the ground to release more line while you work. It uses a sturdier 0.08-inch line and comes with six pre-wound coils in three sets of two, one set already installed. An adjustable auxiliary handle helps with balance. At 5.8 pounds, it is heavier than the 12-inch trimmers. The listing does not mention edger or mower modes.

Choose the HEINPRO if you have a larger lawn and want fewer passes. If light weight matters more, such as for an older gardener, the 4-pound GELIDALITE or 4.2-pound Houselife tools are easier to hold.

Cordless String Trimmer

Best for: Basic trimming with a spare spool

Pros

  • 3-in-1 trimmer, edger, mower
  • Automatic line feed
  • Extra spool and screwdriver

Cons

  • Weight not listed
  • Replacement spool bought separately

The Cordless String Trimmer from worksky (model WKS-D2030-1) is a 12-inch trimmer that fits DeWalt 20V Max batteries, with no battery included. Like the Houselife tools, it converts between trimmer, edger and mower modes, and uses automatic line feed so you do not need to pull line by hand.

The cutting head spins up to 7,000 RPM according to the listing. The head, secondary handle and trimming angle all adjust, and the listing describes a foldable design. The box includes a screwdriver for adjustments and an extra spool of line; replacement spools are sold separately. The listing does not specify the tool’s weight.

This is a straightforward option for someone who wants basic three-mode trimming with a spare spool in the box. Shoppers who want clearer weight and runtime information will find more detail on the GELIDALITE listing.

12-Inch Cordless String Trimmer for Dewalt for Weekly Edging

Best for: Weekly edging on up to 1/2 acre

Pros

  • 9000 RPM motor
  • Guide wheels for edging
  • 6 pre-wound spools
  • Listed runtime by battery size

Cons

  • 12-inch swath for soft weeds
  • Lists specific compatible batteries only

The 12-Inch Cordless String Trimmer for Dewalt batteries, from GELIDALITE (model EF-20ST-001), lists compatibility with the DCB200, DCB203, DCB204, DCB205, DCB206 and DCB240 batteries. It has a 200W copper motor with a listed 9,000 RPM no-load speed, the fastest here, and a 12-inch swath. Quick-attach guide wheels carry the tool’s weight when you use it as an in-line edger along driveways, and it also works as a mini mower.

The auto-feed spool releases 0.4 inches of line each time you start it, and the head accepts standard 0.065-inch line. Six pre-wound spools of 16.5 feet each are included. This is also the only listing that estimates runtime: up to 30 minutes on a 4.0Ah battery and up to 45 minutes on a 6.0Ah battery, suggested for yards up to half an acre. It weighs 4 lbs with a steel shaft, a 0-90° tilting head and a 180° rotating auxiliary handle. The seller lists a 90-day return window and a one-year replacement policy.

This suits regular weekend maintenance on soft weeds and lawn edges. For thicker growth, the listing itself steers you toward lighter work, so the HEINPRO or a blade tool may be the better fit.

Cordless Weed Eater & Leaf Blower for a Two-Tool Yard Kit

Best for: Trim and blow clean in one set

Pros

  • Trimmer plus 400 CFM blower
  • 3-in-1 trimmer modes
  • Light tools: 4.2 and 3 lbs

Cons

  • Listed 30-minute battery life
  • One battery swaps between tools

The Cordless Weed Eater & Leaf Blower combo from Houselife (model HL-DLBSTA-0DB) pairs a 12-inch string trimmer with a handheld leaf blower, both designed for DeWalt 20V MAX XR batteries. The trimmer matches the single Houselife tool above: 8,500 RPM, auto-feed line, 180° adjustable handle, 90° tilting head, dual safety locks, a flower guard, and trimmer, wheeled edger and mini mower modes. It weighs 4.2 lbs.

The 3 lb blower lists 400 CFM and 130 MPH of airflow. CFM (cubic feet per minute) measures how much air moves, while MPH measures how fast it moves; together they tell you how well a blower shifts leaves and grass clippings. The blower uses one-button control. The listing gives a battery average life of 30 minutes, without saying which battery size that figure assumes.

This combo makes a good gift for someone with a small yard, patio or driveway to keep tidy. If you only need a trimmer, the single Houselife tool covers that job on its own.

How to Choose the Right Weed Wacker for DeWalt 20V Batteries

Check your battery. Some listings name exact compatible models, such as the GELIDALITE and OJFAON tools. If you own a battery from your DeWalt 20 volt drill, compare its model number with the list before you buy. A higher Ah (amp-hour) battery generally runs longer.

Match cutting width to yard size. A 12-inch head suits small and medium yards. The 16-inch HEINPRO covers more lawn per pass, while the 8-inch OJFAON blade tool is best for weeds on hard surfaces.

Decide on extra modes. The Houselife, worksky and GELIDALITE tools switch between trimmer, edger and mower. The combo adds a blower for clean-up.

Think about weight and comfort. Tools between 4 and 4.5 lbs are easier for long sessions; adjustable handles and tilting heads help too. For more tools that share the same battery, see our overview of the DeWalt 20 volt platform.

FAQ

Are these weed wackers made by DeWalt?

No. All six are made by third-party brands and designed to fit DeWalt 20V MAX batteries. DeWalt does not make or warranty them; warranties come from each seller.

Do these trimmers come with a battery?

No. Every listing is tool only, with no battery or charger included, so you need your own DeWalt 20V battery.

How long will a battery last in these trimmers?

Only two listings give figures: the GELIDALITE estimates up to 30 minutes on a 4.0Ah battery and 45 on a 6.0Ah, and the combo lists 30 minutes. The others do not specify.

What is the difference between auto feed and bump feed?

Auto feed releases a little line each time you start the tool. Bump feed releases line when you tap the head on the ground, as on the HEINPRO.

Which one is best for a beginner?

A light 12-inch model like the GELIDALITE or Houselife trimmer is easy to handle and converts to an edger, which covers most beginner yard jobs.
