Black and Decker 20V to DeWalt 20V Battery Adapter

This adapter lets you power DeWalt 20V MAX cordless tools with the Black and Decker 20V batteries you already own. Power passes straight through: Black and Decker 20V and DeWalt 20V MAX share the same 20V rating. Constructed from durable molded ABS with pure copper contacts, for a secure fit and dependable current transfer. Fewer battery systems in the workshop, on the bench or in the van, and no extra chargers to find room for.

Why choose this adapter

• Your Black and Decker 20V battery and DeWalt 20V MAX tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
• Injection-moulded ABS, not 3D printed — no layer lines to split under load.
• 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.

Black and Decker 20V and DeWalt 20V MAX compatibility

It works in one direction only: Black and Decker batteries powering DeWalt tools. For the opposite pairing, see adapters that run on DeWalt 20V MAX 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 DeWalt 20V MAX batteries.

Important charging and safety information

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