• 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 Bolt-On compatibility

It works in one direction only: RIDGID 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 RIDGID 18V 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 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.
