Constructed from durable molded ABS with pure copper contacts, for a secure fit and dependable current transfer. Fewer battery systems in the workshop, on the bench or in the van, and no extra chargers to find room for.

Why choose this adapter

• Your Craftsman 20V battery and Craftsman 20V Bolt-On tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
• Injection-moulded ABS, not 3D printed — no layer lines to split under load.
• Solid copper terminals, so less of the current is lost as heat.
• 5 mm² internal wiring, rated for 40A continuous with 80A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
• Covered by a 12-month warranty from the day it arrives.

Craftsman 20V and Craftsman 20V Bolt-On compatibility

It works in one direction only: Craftsman batteries powering Craftsman tools. For the opposite pairing, see adapters that run on Craftsman 20V Bolt-On batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Craftsman 20V platform and that your tool takes Craftsman 20V Bolt-On batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Craftsman or Craftsman batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Craftsman 20V battery.
