• 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.

DeWalt 20V MAX and Metabo HPT 18V compatibility

It works in one direction only: DeWalt 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 DeWalt 20V MAX 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 DeWalt 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 DeWalt 20V MAX battery.
