UGREEN-OS USB-C to 3.5mm DAC & 60W PD Adapter | Model 90518
The UGREEN CM230 (item 90518) is a 2-in-1 USB-C adapter that adds a 3.5mm headphone jack and a USB-C charging port to a phone, tablet or laptop with a single USB-C port. A built-in DAC chip handles the audio, so you can listen with wired headphones and charge at the same time.


Listen and charge together: Plug a USB-C charger into the adapter's USB-C port to keep your device charging while you listen. The charging port supports Power Delivery of up to 60W, and the adapter is rated for 5–20V, 3A max.
Built-in DAC: The adapter has its own DAC chip that converts the digital audio from the USB-C port into an analog signal for the 3.5mm jack. This is what lets wired headphones work on devices that have no headphone jack.
Microphone and in-line control: Headphones with a microphone and in-line buttons work through the 3.5mm jack, so you can take calls and control playback. A switch on the side (Mic 1 / Mic 2) chooses between the adapter's built-in microphone and the headset microphone.
Aluminium shell and braided cable: The body is made of aluminium and the short cable is braided, which makes the adapter sturdy for daily use in a pocket or bag.
