USAMS AU11 2-in-1 USB-C Adapter with 3.5mm Audio Jack, USB-C Charging Port, and Ring Holder - Black

The USAMS AU11 adapter solves the modern smartphone dilemma: how to charge and listen to wired headphones simultaneously when your device has only one USB-C port. This compact 2-in-1 adapter splits a single USB-C connection into a 3.5mm audio jack and a USB-C charging port, both active at the same time. Built with an aluminum alloy shell and TPE strain relief, it’s rugged enough for daily use yet small enough to slip into a pocket. A built-in ring holder doubles as a kickstand, adding convenience for media viewing or video calls.

Overview

Designed for USB-C devices including smartphones, tablets, and laptops, the AU11 supports Power Delivery charging so your device keeps its battery topped up while you enjoy music, podcasts, or calls through wired headphones. The 3.5mm jack delivers stereo sound and supports inline remote controls and microphones, so play/pause, volume, and call management remain at your fingertips. No drivers or software are needed—just plug and play.
