- 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.
Ryobi 18V ONE+ and Craftsman 20V compatibility
It works in one direction only: Ryobi 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 Ryobi 18V ONE+ 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 Ryobi 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 Ryobi 18V ONE+ battery.
