YUHDWRE Milwaukee M12 12V Power Source Adapter with USB-C & DC Port

Overview

Meet the M12 battery charger adapter from YUHDWRE, a compact power source designed to accompany Milwaukee M12 users on the job, at a site, or during outdoor activities. The tiny module slips into tight spaces and keeps you powered when outlets are scarce, making everyday tasks a little easier. Its durable feel and low-profile profile make it a reliable companion for busy days and chilly mornings alike.

What you get is a lightweight, pocket-sized module that taps into the Milwaukee M12 12V ecosystem and provides three convenient outputs: a USB port for 5V/2.1A devices, a QC3.0 18W Type-C port for fast charging, and a 12V DC port (2A) for heated jacket charging. The combination of outputs means you can keep essential gear powered without dragging out multiple chargers.

• USB port (5V/2.1A max) powers smartphones, tablets, earbuds, and small accessories.
• QC3.0 Type-C port (18W) supports compatible devices with fast charging on the go.

Compact and safe design
