Overview

Turn your Milwaukee M18 battery into a flexible 12V power source with the CHoiKWong 18V to 12V step-down converter. This compact adapter pairs space-saving design with rugged ABS construction, making it suitable for indoor workshops and outdoor job sites. It’s designed to stay securely engaged with Milwaukee packs while you focus on the task at hand.

Compatibility and performance

Designed to work with Milwaukee M18 18-volt Li-ion batteries, including models 48-11-1815, 48-11-1820, 48-11-1828, 48-11-1840, 48-11-1850, 48-11-1860, and more. The converter steps 18V down to 12V, delivering up to 20A and up to 240W peak power. The use of synchronous rectification improves efficiency and stabilizes the output for sustained use.
