Makita 18V to Chicago Electric 18V Battery Adapter

Use your Makita 18V LXT batteries on Chicago Electric 18V cordless tools, without buying into a second battery platform. Both run at 18V, so the adapter changes the fitting and not the voltage. Injection-molded ABS on the battery side, precision 3D-printed ABS on the tool side, and pure copper contacts for steady current delivery. A practical way to extend the value of the Makita 18V LXT batteries you already have.

Why choose this adapter

• Your Makita 18V LXT battery and Chicago Electric 18V tools run at the same voltage, so the adapter changes the fitting rather than converting anything.
• 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 Chicago Electric 18V compatibility

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

Important charging and safety information

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