Why choose this adapter

• A Battery Management System inside the adapter cuts power before the battery is drained too far — protection your battery may not have on its own.
• 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.

Makita 18V LXT and MATRIX 20V compatibility

It works in one direction only: Makita batteries powering MATRIX tools. For the opposite pairing, see adapters that run on MATRIX 20V batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Makita 18V LXT platform and that your tool takes MATRIX 20V batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge Makita or MATRIX 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 Makita 18V LXT battery.
