Milwaukee 18V to Makita 18V Battery Adapter

This adapter lets you power Makita 18V LXT cordless tools with the Milwaukee M18 batteries you already own. Both run at 18V, so the adapter changes the fitting and not the voltage. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. One battery platform across more tools means less spent on batteries and less to keep charged.

Why choose this adapter

• Your Milwaukee M18 battery and Makita 18V LXT 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.
• 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.

Milwaukee M18 and Makita 18V LXT compatibility

It works in one direction only: Milwaukee 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 Milwaukee M18 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 Milwaukee 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 Milwaukee M18 battery.
