• 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.
• A USB port on the adapter, so the same battery charges a phone on site.
• Covered by a 12-month warranty from the day it arrives.

Black and Decker 20V and Ryobi 18V ONE+ compatibility

It works in one direction only: Black and Decker batteries powering Ryobi tools. For the opposite pairing, see adapters that run on Ryobi 18V ONE+ batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Black and Decker 20V platform and that your tool takes Ryobi 18V ONE+ batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Black and Decker or Ryobi 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 Black and Decker 20V battery.
