Black and Decker 20V to Makita 18V Battery Adapter

This adapter lets you power Makita 18V LXT cordless tools with the Black and Decker 20V batteries you already own. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. It keeps one battery platform serving more tools, which costs less than buying into another.

Why choose this adapter

• 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.
• A USB port on the adapter, so the same battery charges a phone on site.
• Covered by a 12-month warranty from the day it arrives.

Black and Decker 20V and Makita 18V LXT compatibility

It works in one direction only: Black and Decker batteries powering Makita tools. For the opposite pairing, see adapters that run on Makita 18V LXT 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 Makita 18V LXT batteries.

Important charging and safety information

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