Craftsman 20V to RIDGID 18V Battery Adapter

This adapter lets you power RIDGID 18V cordless tools with the Craftsman 20V batteries you already own. The 3D-printed ABS housing keeps the fit precise, and pure copper contacts keep current delivery steady. It keeps one battery platform serving more tools, which costs less than buying into another.

Craftsman 20V and RIDGID 18V compatibility

It works in one direction only: Craftsman batteries powering RIDGID tools. For the opposite pairing, see adapters that run on RIDGID 18V 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 RIDGID 18V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Craftsman or RIDGID 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.
