Quick verdict
A slide adapter that lets a DeWalt 20V MAX or Milwaukee M18 battery power Craftsman V20 tools, so a garden full of Craftsman trimmers and blowers can run on the packs already bought for the workshop drills. Adapters work because all three platforms are 18 volt nominal lithium; they pass the power and not the brand's communication, so the tool's own protection is what is left. It saves buying a second set of batteries and it voids nothing that was not already out of warranty. Match the listed battery models.
Strengths
- Runs Craftsman V20 tools on DeWalt 20V or Milwaukee M18 packs
- Saves buying and charging a second battery platform
- Slides on and locks like a native pack
- Listed compatibility for common DeWalt DCB and Milwaukee 48-11 packs
- Inexpensive against one new battery
Weaknesses
- Bypasses brand communication; rely on the tool and pack protection
- Adds height and a little wobble under the tool
- Not for use with Craftsman V20 chargers; charge packs on their own charger

Two Brands, One Pile of Batteries
The drills are DeWalt, the string trimmer was a Craftsman bargain, and now there are two chargers and two sets of packs. A battery adapter joins them. ZWDXRB’s slides a DeWalt 20V MAX or Milwaukee M18 pack onto one side and plugs into a Craftsman V20 tool on the other, so the trimmer runs on the drill batteries.
This review is based on the listing specifications and on how passive cross-brand battery adapters work generally. We have not used this adapter ourselves and the brand is a generic importer.
How It Works
DeWalt 20V MAX, Milwaukee M18 and Craftsman V20 are all five-cell 18 volt nominal lithium packs. The adapter is a shaped block of plastic with contacts that connect the pack terminals to the tool terminals and rails that lock to both. The tool sees 18 volts and runs. Nothing is converted; it is a mechanical and electrical bridge.
What Is Lost
Modern packs and tools talk to each other to manage temperature and current. The adapter passes power only. The pack’s own board still cuts off at low voltage and the tool’s own board still limits current, which is why adapters work in practice; the extra layer of brand communication is gone. Stay within the listed pack models, and if a pack or tool gets unusually hot, stop and let it cool. Do not charge through the adapter.
Fit
The adapter adds an inch or so under the tool and a little play. On a trimmer or blower that is unnoticeable; on a compact drill it changes the balance. The listing names the DeWalt DCB and Milwaukee 48-11 packs it fits; check yours against it.
Value
One adapter costs less than one new 4 Ah pack. For someone with four DeWalt batteries and two Craftsman garden tools, it removes a charger from the bench and a platform from the shopping list.
Who Should Buy It
- Owners of DeWalt or Milwaukee packs and Craftsman V20 garden tools.
- Anyone consolidating onto one battery platform.
- Bargain hunters who bought a bare tool cheaply.
Common Owner Complaints
Wobble and the missing brand handshake. Both are inherent to adapters.
Technique Tips
Fit the adapter to the tool first, then slide the pack onto the adapter, and listen for both latches to click; a half-seated pack cuts out under load. Start a new combination on a light job, a trimmer on soft grass, before trusting it on a hedge trimmer in thick growth. Keep the adapter on the tool you use it with rather than swapping it daily, since the latches wear with every change.
Alternatives to Consider
Adapters in other directions for other tool collections. Buying into one platform and selling the other. A second battery for the Craftsman tool.
Verdict
For running Craftsman V20 tools on DeWalt or Milwaukee packs, this adapter does the job and saves a second battery platform. Use the listed packs, charge them on their own chargers and watch for heat.

ZWDXRB Battery Adapter Converting DeWalt 20V MAX and Milwaukee M18 Packs to Craftsman V20 Tools FAQs
All three platforms are 18 volt nominal lithium packs. The adapter connects the pack terminals to the tool terminals and locks mechanically to both, so the tool runs as if on its own battery.
The adapter is passive. Overcurrent and low-voltage protection come from the pack and the tool, not the brand handshake. Stay within the listed battery models and stop if a pack or tool gets unusually hot.
No. Charge DeWalt and Milwaukee packs on their own chargers. The adapter is for running tools only.
Runtime follows the pack: a 5 Ah DeWalt gives roughly a 5 Ah Craftsman worth of work.
