DeWalt 20V MAX and Porter Cable 18V Ni-Cd compatibility

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

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge DeWalt or Porter Cable 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.
