DeWalt Cordless Weed Eater Options for Your 20V Batteries

DeWalt is best known for its yellow-and-black 20V MAX battery platform, which powers drills, saws and a wide range of outdoor tools. Once you own a couple of those batteries, it makes sense to look for a DeWalt cordless weed eater that runs on them so you do not have to buy a second battery system. A weed eater, also called a string trimmer or weed wacker, spins a plastic line fast enough to cut grass where a mower cannot reach.
One honest note before we start: all six trimmers here are made by other companies (Houselife, HEINPRO, GELIDALITE, AXORIX and Lx2crya) to fit DeWalt 20V MAX batteries, and they differ mainly in cutting width, weight and whether they add an edger, a leaf blower or metal blades, so none of them is an official DeWalt tool.

Cordless Weed Wacker Compatible with DEWALT
Best for: Small yards needing trim, edge and mow
Pros
- 3-in-1 trimmer, edger, mini mower
- Light at 4.2 lbs
- Auto and manual line feed
- Flower guard
Cons
- Battery and charger not included
- Houselife-made, not DeWalt
The Cordless Weed Wacker Compatible with DEWALT is a Houselife bare tool, which means the battery and charger are not included; you slot in a DeWalt 20V MAX battery you already own. It has a 12-inch cutting diameter, an 8500 RPM copper wire motor and a 1-year manufacturer warranty.
It is a 3-in-1 tool: a string trimmer, an in-line wheeled edger for crisp lines along paths, and a “mini mower” mode for small patches of grass. The line feed works two ways. Auto feed releases 0.4 inch of line every time you start the tool, and the listing mentions a second, manual option as well. At 4.2 lbs, with a 180-degree adjustable auxiliary handle, a 90-degree tilting head, a flower guard and a dual safety lock, it is aimed at comfortable, low-fatigue use.
This model suits a first-time homeowner with a modest yard who wants one light tool for trimming and edging. If your lawn is larger or has thick growth, the wider HEINPRO below covers more ground per pass.
HEINPRO Cordless Weed Wacker Compatible for Wider Cutting
Heinpro
HEINPRO Cordless Weed Wacker Compatible with DeWalt 20V MAX Battery
Price and specifications are read from the Amazon product page and can change.
HEINPRO Cordless Weed Wacker Compatible
Best for: Bigger lawns wanting a wider swath
Pros
- 16-inch cutting swath
- Brushless motor
- Thicker 0.08-inch line
- Spare line coils
Cons
- Heaviest single trimmer at 5.8 lbs
- Coil count listed two ways
The HEINPRO Cordless Weed Wacker Compatible is the widest cutter in this group, with a 16-inch swath. “Swath” is the width of the circle the line cuts, so a bigger number means fewer passes. It uses a brushless motor, which runs cooler and more efficiently than a brushed motor because it has no carbon brushes rubbing inside, and spins at 6000 RPM with thicker 0.08-inch line.
It uses bump feed: tap the head on the ground and it lets out more line. The listing says you get six pre-wound coils arranged as three sets of two, with one set already installed, though the highlight line mentions four bulk coils, so expect at least a couple of spares. It weighs 5.8 lbs and has an adjustable auxiliary handle. Battery and charger are not included.
Pick this one if you have a bigger lawn, long fence lines or tougher grass. It does not list edger or mower modes, so if neat edging matters more than width, the 12-inch wheeled models suit you better.
12-Inch Cordless String Trimmer for Dewalt for Neat Edging

12-Inch Cordless String Trimmer for Dewalt
Best for: Weekly edging on sidewalks and driveways
Pros
- Guide wheels for edging
- Named DeWalt battery models
- Six spare spools
- Runtime estimates given
Cons
- Built for soft weeds
- GELIDALITE-made, not DeWalt
The 12-Inch Cordless String Trimmer for Dewalt from GELIDALITE names the exact DeWalt batteries it takes: DCB200, DCB203, DCB204, DCB205, DCB206 and DCB240. It is a 3-in-1 trimmer, edger and mini mower, with quick-attach guide wheels that carry the tool’s weight as you roll along a driveway or sidewalk.
It has a 200W copper motor at 9000 RPM, a 12-inch swath and auto feed that releases 0.4 inch of line at each start. It takes standard 0.065-inch line and comes with six pre-wound spools of 16.5 feet each. The seller estimates about 30 minutes of trimming with a 4.0Ah battery and up to 45 minutes with a 6.0Ah battery, and says it is optimized for weekly maintenance and soft weeds. It weighs about 4 lbs with a steel shaft.
This is the one for tidy suburban yards cut every week, where crisp edges matter. It is not meant for overgrown brush; for that, look at the blade-equipped Lx2crya model.
Cordless Weed Eater & Leaf Blower for a Two-Tool Yard Kit
Houselife
Cordless Weed Eater & Leaf Blower Combo Compatible with Dewalt 20V Battery
Price and specifications are read from the Amazon product page and can change.
Cordless Weed Eater & Leaf Blower
Best for: One-battery trim and cleanup kit
Pros
- Trimmer plus leaf blower
- 400 CFM / 130 MPH blower
- 3-in-1 trimmer head
Cons
- Battery not included
- One battery swaps between tools
The Cordless Weed Eater & Leaf Blower combo from Houselife pairs a 4.2 lb trimmer with a 3 lb handheld blower, both running on the same DeWalt 20V battery (not included). The trimmer matches the solo Houselife model: 12-inch cut, 8500 RPM, auto feed, 3-in-1 trimmer, edger and mini mower, a 180-degree handle and a 90-degree tilting head.
The blower is rated at 400 CFM and 130 MPH. CFM (cubic feet per minute) is how much air moves; MPH is how fast it moves. Together they describe how well a blower sweeps leaves and grass clippings off driveways and patios. The blower uses a simple one-button control. The listing gives about 30 minutes of average battery life, and the dimension line reads 1 by 1 inch, which is clearly a listing error.
This combo suits a gift for a new homeowner who already has DeWalt batteries and wants to trim and clean up in one session. If you own only one battery, you will swap it between the tools.
Weed Wacker Cordless Compatible with DEWALT for Trimming and Edging
Best for: Clean lawn edges on a budget of effort
Pros
- Trimmer and edger modes
- Auxiliary wheel
- Six spare spools
- 12,000 RPM listed
Cons
- Cutting width listed as 11 and 12 inches
- AXORIX-made, not DeWalt
The Weed Wacker Cordless Compatible with DEWALT from AXORIX is a 2-in-1 string trimmer and edger. You rotate the shaft and adjust the head to switch modes, and an auxiliary wheel adds stability for edging. Battery and charger are not included.
The listing claims up to 12,000 RPM, the highest line speed among the string models here, along with single-sided automatic line feed and six pre-wound spools. It weighs 4.5 lbs and has a 180-degree handle, a 90-degree rotating head, a dual-switch safety system and a debris guard. The title and features say 12-inch cutting width while the spec sheet says 11 inches, so expect roughly that size.
It suits readers who mainly want a trimmer that also edges well, without a mower mode they may never use. If you want a wheeled edger with named battery models, the GELIDALITE is a close alternative.
Cordless Weed Wacker for Dewalt 20V for Brush and Tough Weeds
The Cordless Weed Wacker for Dewalt 20V from Lx2crya is really a light brush cutter. Instead of relying only on string, it ships with four types of cutting head: trimmer line for soft lawns, stainless steel blades for older weeds, alloy saw blades for small branches and a grass brush for moss. The box includes two circular saw blades, two straight blades, two three-corner blades, a grass rope, a grass brush, a glove, a tool kit and a shoulder strap.
The pole adjusts from 37 to 53 inches and the tool weighs 4.3 lbs. It lists compatible batteries including DCB200, DCB203, DCB205, DCB240 and DCBP520. Some specs are hard to trust: the listing claims a 1300W brushless motor and 23,000 RPM, gives a 6-inch cutting width and says two AA batteries are required, which does not fit a DeWalt-powered tool. Treat those numbers with caution.
This suits someone clearing an overgrown corner, a fence line with woody weeds or mossy patio cracks. Metal blades need more care than string, so a first-time buyer with a neat lawn will be happier with one of the string models above.
How to Choose the Right DeWalt Compatible Weed Eater
Start with your battery. All six are tool-only, so check that you own a DeWalt 20V MAX battery; the GELIDALITE and Lx2crya listings name specific models. A 4.0Ah or larger pack gives noticeably longer sessions than a small 2.0Ah pack. If you are building up your battery collection, our look at a DeWalt cordless compressor shows another handy tool on the same platform.
Next, match cutting width to yard size. A 12-inch head is plenty for small and medium yards, while the 16-inch HEINPRO saves time on large lawns.
Then think about the jobs. For edging along paths, choose a wheeled model such as the GELIDALITE, AXORIX or Houselife. For clean-up after trimming, the Houselife combo adds a blower. For thick weeds and brush, the Lx2crya’s blades are the answer.
Finally, consider weight and comfort. Everything here sits between about 4 and 5.8 lbs, and adjustable handles help. If you would rather compare an official tool, our guide to the DeWalt 20 volt weed wacker covers DeWalt’s own model.
FAQ
Are these trimmers made by DeWalt?
No. They are made by other brands to accept DeWalt 20V MAX batteries. DeWalt does not make or warranty them.
Do any of them include a battery?
No. Every listing says tool only, so you need your own DeWalt 20V MAX battery and charger.
What is the difference between auto feed and bump feed?
Auto feed lets out a little line each time you start the tool. Bump feed lets out line when you tap the head on the ground, as on the HEINPRO.
Which one has the widest cut?
The HEINPRO, with a 16-inch cutting swath. Most of the others cut about 12 inches.
Which is best as a gift?
For someone who already owns DeWalt batteries, the Houselife weed eater and leaf blower combo covers two jobs in one box.
Can these cut small branches?
Only the Lx2crya model lists saw blades for branches. The string trimmers are meant for grass and soft weeds.
