If you searched “craftsman v20 adapter” hoping for a battery-platform bridge, the short answer is simple: Craftsman does not make an official adapter that lets V20 batteries run tools from another brand, voltage, or platform. The two accessories that come closest are both portable power sources, not compatibility bridges. They turn a V20 battery pack into a USB/AC charging station, which is genuinely useful on a jobsite, but neither one solves the “will this battery fit that tool” problem.
What Craftsman actually sells under the adapter-adjacent category
Craftsman’s own V20 pages list exactly two products that shoppers sometimes confuse with cross-platform adapters: the V20 USB Power Source, Tool Only (CMCB002B), and the V20 Portable Power Station/Inverter (150 Watt), Tool Only (CMCB1150B). Both clip onto a V20 battery and export power for personal electronics. Neither converts V20 to DeWalt 20V Max, Porter-Cable 20V, the short-lived 2018 “Craftsman 20V”/DieHard line, or any other cordless tool voltage.
The CMCB002B is the smaller of the two. According to Craftsman, it has a “Single USB port for charging compatible devices like phones, tablets and more,” and delivers “2.1a output current for rapid charging rate.” The company describes it as “Part of the V20 cordless power tool and outdoor equipment system” and “Part of the growing V20 Lithium Ion System.” It is a compact way to keep a phone alive on a job, not a way to keep a drill running on a different battery.
The CMCB1150B is the more serious power source. It “delivers charging for a wide variety of devices 150 watts,” with “3 Unique Charging Ports: (1) type-a, (1) type-c, (1) AC.” It also includes an “LED Flashlight [that] Provides light in dark workspaces” and a “Durable rubber overmold.” For organization, it is “VERSATRACK compatible (sold separately),” and it carries a “3 Year Limited Warranty.”
How Craftsman compares to the rest of the market
This puts Craftsman in the same camp as DeWalt, Milwaukee, and RIDGID: brands that do not offer a first-party cross-platform battery adapter. RYOBI, Makita, and Bosch are the contrast; each does sell real cross-platform bridges for at least some of its battery systems, and this site covers those separately. The distinction matters because the word “adapter” gets used loosely online, and a shopper can easily end up on a product page for a USB power source expecting a battery-to-tool adapter. With Craftsman, the difference is worth reading carefully.
It is also worth noting the ownership context, because it is a common source of confusion. Stanley Black & Decker owns Craftsman, DeWalt, and Porter-Cable, all of which operate on similar 20V Max-style lithium-ion platforms. Despite that shared ownership, none of those brands officially supports swapping battery packs with one another. DeWalt’s 20V Max, Craftsman’s V20, and Porter-Cable’s 20V lines use their own physical mounts and battery-management handshakes. So if you are hoping Stanley Black & Decker quietly made a universal adapter behind the scenes, the answer is no.
What about the old “Craftsman 20V”/DieHard line?
The 2018-era “Craftsman 20V” tools sold with DieHard batteries are a separate story, and Craftsman does not list an official bridge from V20 to that older line either. If you are trying to keep older red-and-black Craftsman 20V tools running, you are generally looking at buying into that older battery ecosystem or exploring third-party options, not an official Craftsman adapter. This guide focuses on V20, but the same no-official-bridge rule applies there too.
Practical takeaway
Neither Craftsman accessory is a battery-platform bridge. Both turn a V20 battery into portable USB/AC power, which is a genuinely useful thing on its own, just not what “adapter” usually means in a compatibility context. No official Craftsman adapter bridges V20 to the old incompatible Craftsman 20V/DieHard line, and none bridges to DeWalt or Porter-Cable despite shared Stanley Black & Decker ownership. If you are looking for a way to use a different brand’s battery in a Craftsman tool, or a Craftsman battery elsewhere, that product does not officially exist. If you just want portable power from a V20 battery you already own, the CMCB1150B (150W, three port types, VERSATRACK-mountable) is the more capable of the two options.
