RIDGID 18V to Craftsman 20V Battery Adapter

Use your RIDGID 18V batteries on Craftsman 20V cordless tools, without buying into a second battery platform. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. 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

• 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.
• Made for the RIDGID 18V batteries sold at Home Depot, so the fit is the one you already own.
• Covered by a 12-month warranty from the day it arrives.

RIDGID 18V and Craftsman 20V compatibility

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

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the RIDGID 18V platform and that your tool takes Craftsman 20V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge RIDGID 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 RIDGID 18V battery.
