DeWalt 20V Weedeaters: Genuine Models vs Compatible Trimmers

Best for
Buyers wanting a genuine DeWalt kit

The DEWALT DCST925M1R 20V MAX Lithium-Ion Cordless string trimmer kit is the DeWalt DCST925 renewed. It is sold through Amazon Renewed, so it is a refurbished unit rather than new, but it is genuine DeWalt hardware. The title lists a 4 Ah battery as part of the kit, and the specs count three items, which fits a trimmer, battery and charger, although the listing does not spell out the contents.

It offers a 13-inch cutting swath with 0.080-inch line and a gear drive transmission that DeWalt says amplifies torque through overgrowth. The variable-speed trigger and high/low switch let you trade power for runtime. The listing gives an item weight of 12 pounds, which likely includes packaging and the battery.

This is the pick if you want the DeWalt name and a battery without buying a new kit. If you already have batteries and want a slightly wider cut plus folding storage, the DCST922B is the better genuine option.

• 13-inch swath with 0.080-inch line
• Gear drive transmission
• Variable trigger with high/low speed control
• Uses the same batteries and chargers as other 20V MAX tools

Wide swaths on a budget of batteries

The HEINPRO Cordless Weed Wacker Compatible with DeWalt 20V MAX batteries is a third-party string trimmer, not a DeWalt product, and the battery and charger are not included. Its headline number is a 16-inch cutting swath, the widest in this group, driven by a brushless motor rated at 6,000 RPM with 0.08-inch line.

It uses a bump feed head, so you tap the head on the ground to advance line, and an adjustable auxiliary handle. The bullets say it ships with six pre-wound line coils in three sets of two, one set installed, while the item highlight mentions four coils; expect at least four. The listing gives a weight of 5.8 pounds.

This is a string trimmer compatible with DeWalt battery packs for bigger lawns where swath width saves passes. It gives way to the DCST922B if you want genuine DeWalt build and a folding shaft.

• 16-inch swath
• Brushless motor, 6,000 RPM
• Bump feed line advancement
• Spare pre-wound line coils

Best for
DeWalt owners with limited storage

The Dewalt DCST922B 20V MAX 14 in folding string trimmer is the genuine DeWalt weed wacker bare tool in this lineup. The box holds the trimmer, a guard and a handle, with no battery or charger. Its signature feature is a folding hinge that the description says cuts the length by 40 percent, making it easy to hang in a crowded garage or slide into a car trunk.

The DeWalt DCST922B is brushless and variable speed, with a Hi/Lo switch and a QuickLoad spool for fast replacement of 0.080-inch line across a 14-inch swath. The specs list 6,000 RPM and a weight of 7.3 pounds, heavier than the compatible trimmers but in line with a full-size shaft. It works with FLEXVOLT and POWERSTACK batteries as part of the 20V MAX system.

If you already own DeWalt batteries, this is the most straightforward answer to which DeWalt 20V trimmer to buy. For a battery in the box, choose the renewed DCST925 instead. Our DeWalt battery powered weed eater guide covers more of the lineup.

• Folding hinge reduces length by 40 percent
• Brushless motor with variable speed
• QuickLoad spool, 0.080-inch line
• 14-inch cutting swath

The Cordless Weed Wacker Compatible with DEWALT batteries is made by Houselife, model HL-DST30A-0DB, and sold as a tool only. Its pitch is versatility: a 3-in-1 design that switches between string trimmer, in-line wheeled edger and mini lawn mower, with a flower guard to protect plants.

The listing quotes a copper wire motor with an 8,500 RPM no-load speed, a 12-inch cutting diameter, and a dual line feed that includes an auto feed releasing 0.4 inches of line each time you start the tool. It weighs 4.2 lbs, with a 180-degree adjustable handle, a 90-degree tilting head, a dual safety lock and a one-year warranty.

This suits small yards and garden borders where one light tool can trim, edge and tidy. It gives way to the HEINPRO or a DeWalt model for larger, tougher lawns.

The 12-Inch Cordless String Trimmer for Dewalt batteries is a GELIDALITE tool-only trimmer and the most specific about fit and runtime. It names compatible DeWalt batteries, including DCB200, DCB203, DCB204, DCB205, DCB206 and DCB240, and says a 4.0Ah pack gives up to 30 minutes of trimming while a 6.0Ah pack stretches that to about 45 minutes, for yards up to half an acre.

It is a 3-in-1 trimmer, edger and mini mower with quick-attach guide wheels. The listing quotes a 200W copper motor at 9,000 RPM, a 12-inch swath, an auto-feed spool, and six pre-wound spools of 0.065-inch line. It weighs 4 lbs with a steel shaft, has a 0 to 90-degree tilting head and a 180-degree rotating handle, and comes with a return and replacement guarantee.

This suits weekly edging and soft-weed maintenance. The thinner line is less suited to thick overgrowth, where the 0.080-inch DeWalt models are better equipped.

The Cordless String Trimmer from worksky, model WKS-D2030-1, is compatible with DeWalt 20V MAX batteries and arrives with no battery. It is a 3-in-1 trimmer, edger and mower with a 12-inch cutting diameter, automatic line feed and a cutting head rated up to 7,000 RPM.

The package includes a screwdriver for adjustments and an extra spool of line. The head, secondary handle and trimming angle are adjustable, and the item highlight describes it as foldable. The listing does not specify weight, line diameter or warranty.

This suits light trimming around a modest yard for someone who wants a spare spool in the box. For more detail on runtime and fit, the GELIDALITE listing is more thorough. If you are building out a 20V garden kit, our DeWalt 20V jobsite blower guide pairs well for cleanup.
