  • 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 Stanley V20 compatibility

It works in one direction only: Ryobi batteries powering Stanley tools. For the opposite pairing, see adapters that run on Stanley V20 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 Stanley V20 batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Ryobi or Stanley 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.
