Quick verdict
A 58V brushless string trimmer with three speed settings, a 15-inch swath, a bump-feed head and a shaft that splits to take DCK pole saw, hedge trimmer and edger attachments. The 4.0 Ah pack is rated for up to 90 minutes and charges in 48 minutes, which is generous for a trimmer kit. The caveats are an 11.5-pound tool body, which is heavy for the class, and a battery platform with few other tools behind it.
Strengths
- 58V brushless motor with 4000, 5000 and 6000 RPM settings
- 4.0 Ah pack rated for up to 90 minutes
- 5A charger with cell cooling, 48-minute refill
- Shaft-release button takes DCK attachments
- Shoulder strap and adjustable loop handle included
- 5-year tool and 3-year battery warranty stated
Weaknesses
- 11.5 pounds for the tool body alone is heavy for a trimmer
- Few other tools share the DCK 58V battery
- Bump head needs manual rewinding, no auto-wind
- Attachments are sold separately and only from DCK

Who this trimmer is for
Most battery trimmer kits ship with a small pack and leave you to buy a bigger one. The DCK 58V kit goes the other way: a 4.0 Ah battery rated for up to 90 minutes, a 5A fast charger, a shoulder strap and a shaft that splits to take other DCK heads. It is pitched at the owner of a half-acre lot who wants a long session on one charge and is willing to try a lesser-known brand to get it.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
The box holds the trimmer, a 58V 4.0 Ah lithium pack, a 5A charger with active cell cooling, a shoulder strap and the adjustable loop handle. DCK states a 15-inch cutting swath, a bump auto-feed head with a quick-reload spool, three speed settings at 4000, 5000 and 6000 RPM, a tool-body weight of 11.5 pounds, and a shaft-release button for its pole saw, pole hedge trimmer and edger attachments, all sold separately. The listing also states a 5-year tool warranty and a 3-year battery warranty, with ETL listing.
Cutting and speed settings
Three fixed speeds are the practical feature here. The 4000 RPM setting is for edging a bed without flinging mulch and for stretching runtime; 5000 RPM covers weekly grass; 6000 RPM is for the fence line that grew a crop of thistles. DCK’s claim of 80 percent more power is marketing against an unnamed baseline and should be ignored, but a 58V brushless motor is a credible size for a 15-inch head. Line diameter is not stated in the listing. Owners of this class of trimmer generally report good cutting in grass and light weeds and a slowdown in woody stems, which is where a dedicated brush cutter belongs anyway.
Runtime and charging
A 4.0 Ah pack at 58V holds roughly 230 watt-hours, which is why DCK can quote up to 90 minutes. Expect that figure on the low setting in light grass and perhaps half of it at 6000 RPM in thick growth. The 5A charger with cell cooling refills the pack in about 48 minutes per DCK, so a second long session is possible the same morning. The weak point is the platform: DCK’s 58V line is small compared with EGO, Greenworks or Ryobi, so this pack is unlikely to power much else in your shed.
Build, handling and ergonomics
At 11.5 pounds before the battery, this is a heavy trimmer. A typical 15-inch battery trimmer lands several pounds lighter, so the included shoulder strap is a necessity rather than an accessory. The adjustable loop handle and rubber grip help with the balance, and the attachment-capable split shaft explains some of the mass, since the coupler and the stronger tube add weight. The multi-head coupling is a genuine plus if you want a pole saw or hedge trimmer on the same motor and pack later.
Living with it
The bump head feeds line on the fly, but rewinding is manual; DCK says the quick-reload spool makes that fast, and owners of similar heads report a few minutes per reload. Keep a spare spool of the correct diameter, which you will need to confirm from the manual since the listing omits it. Clean the guard after wet cuts, store the pack indoors at partial charge over winter, and register the warranty on purchase.
Alternatives to Consider
The EGO Power+ ST1511T is lighter and has the Powerload auto-wind head, with a smaller 2.5 Ah pack and a far larger range of tools on its battery. The Ryobi 40V HP 15-inch attachment-capable trimmer takes the Ryobi Expand-It heads and has a huge battery ecosystem behind it. The Greenworks 80V 16-inch trimmer is another brushless option with a bigger dealer footprint.
Verdict
Buy the DCK 58V 15-inch trimmer if runtime per charge is your priority, you want a shoulder strap and a big pack in the box, and you plan to add a DCK pole saw or hedge trimmer to the same shaft. Skip it if weight matters, if you want an auto-winding head, or if you would rather buy into a battery platform with dozens of tools and years of parts support.

DCK 58V Cordless 15-Inch Brushless String Trimmer with 4.0 Ah Battery and 5A Charger FAQs
DCK lists its own pole saw, pole hedge trimmer and edger attachments, all sold separately. The listing does not claim compatibility with other brands' attachment systems, so assume it is DCK only.
DCK rates it for up to 90 minutes. That will be on the 4000 RPM setting in light grass; the 6000 RPM setting in thick weeds will cut it considerably, as with any battery trimmer.
DCK states 11.5 pounds for the tool body, before the battery. That is heavier than most 15-inch battery trimmers, which is why the shoulder strap is in the box and worth using.
The listing states a 5-year tool warranty and a 3-year battery warranty, and says the tool is ETL listed. Register it and keep the receipt, since lesser-known brands tend to need both for a claim.
