DeWalt is best known in the outdoor category for its 20V MAX battery platform, the same yellow-and-black batteries that power its drills, drivers and yard tools. That is exactly why so many people search for a “DeWalt weed whip”: they already own the batteries and want a trimmer that clicks onto them. An important point before we start: every trimmer in this guide is a third-party tool made by another company (Houselife, worksky, OJFAON, HEINPRO, Bavpelp and MtiolHig) and designed to fit DeWalt 20V MAX batteries. None of them is made or endorsed by DeWalt, and each one is sold tool only, which means no battery and no charger in the box.
The six models below differ mainly in cutting width, in the type of cutting head (auto-feed string, bump-feed string or interchangeable blades) and in extras such as a leaf blower or a telescopic pole.
DeWalt Compatible String Trimmers Compared
| Model | Cutting width | Line feed or head | Motor speed listed | Extras |
|---|---|---|---|---|
| Houselife Weed Eater and Leaf Blower | 12 inches | Auto feed | 8,500 RPM | Leaf blower |
| worksky Cordless String Trimmer | 12 inches | Auto feed | 7,000 RPM | Spare spool |
| OJFAON Weed Wacker | 8 inches | 4 interchangeable heads | Not listed | Blades, gloves, eye mask |
| HEINPRO Weed Wacker | 16 inches | Bump feed | 6,000 RPM | Spare line coils |
| Bavpelp Weed Wacker | 12 inches (title) | 4 interchangeable heads | 23,000 RPM (spec) | Blades, grass brush |
| MtiolHig String Trimmer | 12 inches | String, feed type not listed | 8,500 RPM | Battery level display |
A few terms in plain words. “Cutting width” or “swath” is how wide a strip of grass the trimmer clears in one pass. “Auto feed” lets out fresh line on its own as it wears down, while “bump feed” releases line when you tap the head on the ground. Blade heads swap the string for metal or plastic blades that handle thicker weeds and small brush.

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: Small yards needing trimmer and blower
Pros
- Trimmer plus leaf blower
- Auto line feed
- Converts to edger and mini mower
- Blower rated 400 CFM
Cons
- Battery and charger not included
- Third-party, not made by DeWalt
The Cordless Weed Eater & Leaf Blower from Houselife is a bare-tool combo: a 12 inch string trimmer and a handheld leaf blower, both designed for DeWalt 20V MAX XR batteries. The listing says the trimmer weighs 4.2 lbs and the blower 3 lbs, with 7.2 pounds as the combined item weight.
The trimmer runs at 8,500 RPM with an auto-feed line system, and a 180-degree adjustable handle plus a 90-degree tilting head let it switch between trimmer, wheeled edger and mini mower. It has dual safety locks and a flower guard to protect plants. The blower is listed at 400 CFM and 130 MPH with one-button control and a slim nozzle for tight spaces. The listing gives a battery life of about 30 minutes but does not say which battery size that figure assumes.
This is the pick for someone searching for a weed eater and leaf blower combo for DeWalt batteries, especially with a small yard, patio or driveway. For a bigger lawn, the wider HEINPRO below covers more ground per pass.
Cordless String Trimmer for Straightforward Trimming
Best for: Tall users and compact storage
Pros
- Brushless 8500 RPM motor
- Battery level display
- 50-60 inch telescopic shaft
- Folds to 28 inches
Cons
- Weight listed as 5.5 and 6 lbs
- Tool only
Worksky
Cordless String Trimmer (No Battery) Compatible with Dewalt 20V Max Battery
Price and specifications are read from the Amazon product page and can change.
Cordless String Trimmer
Best for: Simple trimming with a spare spool
Pros
- Auto line feed
- Extra spool included
- Trimmer, edger and mower modes
Cons
- No battery included
- Lower 7000 RPM head speed
The Cordless String Trimmer from worksky is a basic 12 inch trimmer for DeWalt 20V MAX batteries, sold with no battery. The box includes a small screwdriver tool and an extra spool of line, which helps first-time owners who do not yet know where to buy replacements.
It uses automatic line feed, so you do not need to pull line by hand, and its cutting head spins at up to 7,000 RPM. Like several models here it converts between trimmer, edger and mower modes, and the head angle, secondary handle and trimming angle are all adjustable. The listing gives a length of 47.2 inches but does not specify the weight.
It suits someone who just wants a simple trimmer for lawn edges and fence lines. It gives way to the higher-speed Houselife or MtiolHig models if the grass tends to be thick.
Cordless Weed Wacker for DeWalt 20V with Interchangeable Blades
Best for: Light brush and moss clearing
Pros
- Four cutting attachments
- Adjustable 37-53 inch pole
- Light for the category
Cons
- Specs contradict each other
- Motor claims look inflated
Ojfaon
Cordless Weed Wacker for DeWalt 20V MAX Battery
Price and specifications are read from the Amazon product page and can change.
Cordless Weed Wacker for DeWalt 20V
Best for: Mixed weeds, moss and small brush
Pros
- Four blade types included
- Telescopic 36-52 inch pole
- Gloves and eye protection included
Cons
- 8 inch cutting width
- Weight listed two ways
The Cordless Weed Wacker for DeWalt 20V made by OJFAON is less a string trimmer and more a 4-in-1 weeder, lawn trimmer, edger and brush cutter. The listing names compatible DeWalt 20V MAX batteries including DCB200, DCB203, DCB205, DCB240 and DCBP520, among others.
The kit includes 2 circular saw blades, 2 stainless steel blades, a grass rope, a grass brush for moss and paving, gloves, an eye mask and a tool kit. The telescopic pole adjusts from 36 to 52 inches, and there are dual safety switches and splash guards. The listing claims 4.5 pounds in the feature text but 7 pounds in the specifications, and its cutting width is only 8 inches.
Choose it for patios, gravel paths and small overgrown corners rather than wide lawns. The HEINPRO covers much more lawn per pass.
HEINPRO Cordless Weed Wacker Compatible for Larger Lawns
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: Larger lawns needing a wider cut
Pros
- 16 inch cutting swath
- Brushless motor
- Bump feed head
- Spare line coils included
Cons
- Battery and charger not included
- Coil count listed inconsistently
The HEINPRO Cordless Weed Wacker Compatible model offers the widest cut in this list at 16 inches, which means fewer passes on a larger lawn. It uses a brushless motor, which the listing says brings better efficiency, less heat and a longer service life.
The motor runs at 6,000 RPM with a durable 0.08 inch line and a bump-feed head. It has an adjustable auxiliary handle and weighs 5.8 pounds. The feature list says it comes with 6 pre-wound line coils arranged as 3 sets of 2, while another line on the listing says 4 coils, so expect at least spares but check the exact count. Battery and charger are not included.
This model suits owners of a medium or large lawn who want the most traditional string-trimmer layout. If you are building out a DeWalt battery kit, our DeWalt 20 volt weed wacker guide explains the brand’s own options too.
Cordless Weed Wacker for Dewalt 20V with Four Cutting Attachments
The Cordless Weed Wacker for Dewalt 20V made by Bavpelp is another 4-in-1 blade-style tool with trimmer line, stainless steel blades, alloy saw blades and a grass brush. The adjustable pole runs from 37 to 53 inches, and the listing names the same range of compatible DeWalt 20V MAX batteries as the OJFAON model.
This listing needs care. The title says a 12 inch cut while the spec table says 12 centimeters; the text claims 4.3 pounds and the spec says 1 kg; and the feature text mentions a “13000W brushless motor,” a figure that is far beyond what a 20V battery can deliver, alongside a 23,000 RPM spec. We would not rely on those performance numbers.
It may suit light moss and weed clearing on paths, but for dependable specs, the HEINPRO or MtiolHig listings are clearer.
Cordless String Trimmer Compatible with Dewalt for Tall Users
The Cordless String Trimmer Compatible with Dewalt from MtiolHig has a brushless motor at 8,500 RPM no-load speed, a 12 inch cutting width and a built-in battery level display so you are not surprised by a shutdown.
Adjustability is its strength: a 75-degree tilting head, a 90-degree rotating handle and a 50 to 60 inch telescopic shaft, which suits taller users. It converts between trimmer, edger and mower and folds to 28 inches for storage. Weight is given as 5.5 lbs in the text and 6 pounds in the specs.
Choose it if comfort and storage matter most. Once you are on DeWalt batteries, the same packs also run shop tools like a DeWalt 1/2 inch impact wrench.
How to Choose the Right DeWalt Compatible String Trimmer
Check the battery. All six are tool only. Confirm your battery is a DeWalt 20V MAX pack; the OJFAON and Bavpelp listings name specific compatible battery models.
Match the cutting width to your yard. The 16 inch HEINPRO suits bigger lawns; the 12 inch models suit small to medium yards; the 8 inch OJFAON is for tight spots.
String or blades. String heads are safest around fences and flower beds. Blade kits (OJFAON, Bavpelp) handle tougher weeds and moss.
Extras. Pick the Houselife combo if you also want a blower, or the MtiolHig for its battery display and telescopic shaft.
