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.
Covered by a 12-month warranty from the day it arrives.

Makita 18V LXT and DeWalt 20V MAX compatibility

It works in one direction only: Makita 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 Makita 18V LXT 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 Makita 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 Makita 18V LXT battery.
