Makita 18V to Ryobi 18V Battery Adapter

This adapter lets you power Ryobi 18V ONE+ cordless tools with the Makita 18V LXT batteries you already own. Both platforms are rated 18V, so torque and speed on the Ryobi 18V ONE+ tool stay where they should be. Built with a durable injection-molded ABS housing and pure copper contacts for steady current delivery. It is a cost-effective way to get more from the batteries you have, with no second charger to maintain.

Why choose this adapter

• Your Makita 18V LXT battery and Ryobi 18V ONE+ 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.
• Covered by a 12-month warranty from the day it arrives.

Makita 18V LXT and Ryobi 18V ONE+ compatibility

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

Important charging and safety information

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