Black and Decker 20V and Metabo HPT 18V compatibility

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

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Black and Decker or Metabo HPT 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.
