Black and Decker 20V to Stanley V20 Battery Adapter

Use your Black and Decker 20V batteries on Stanley V20 cordless tools, without buying into a second battery platform. Both platforms are rated 20V, so torque and speed on the Stanley V20 tool stay where they should be. Built with a durable injection-molded ABS housing and pure copper contacts for steady current delivery. It keeps one battery platform serving more tools, which costs less than buying into another.

Why choose this adapter

• Your Black and Decker 20V battery and Stanley V20 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 Stanley V20 compatibility

It works in one direction only: Black and Decker batteries powering Stanley tools. For the opposite pairing, see adapters that run on Stanley V20 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 Stanley V20 batteries.

Important charging and safety information

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