DeWalt 20V MAX and Hikoki 18V compatibility

It works in one direction only: DeWalt batteries powering Hikoki tools. For the opposite pairing, see adapters that run on Hikoki 18V batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the DeWalt 20V MAX platform and that your tool takes Hikoki 18V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge DeWalt or Hikoki 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 DeWalt 20V MAX battery.
