UGREEN USB-C Audio + 60W Charging Adapter (25837)
The UGREEN USB-C Audio and Charging Adapter (25837) gives a USB-C phone, tablet or laptop a 3.5mm headphone jack and a USB-C charging port at the same time. A Hi-Res DAC decodes up to 32bit/384kHz for clean, detailed sound, and the second port passes up to 60W PD fast charging, so your wired headphones, car AUX and charger can all share one USB-C port.
A separate 32bit/384kHz DAC chip handles your music while a PD 60W charging chip manages power, so audio and charging run side by side without fighting over one port.
Hi-Res Audio decoding and a signal-to-noise ratio above 110dB keep music, podcasts and calls clear and free of background hiss on your favourite wired headphones.
Plug your USB-C charger into the second port and the adapter passes up to 60W to your device, with PD 3.0/2.0, PPS, QC 4.0/3.0, AFC and SCP support, so a long playlist or game never drains the battery.
A nylon-braided cable, aluminium alloy shell and reinforced strain relief are tested to more than 20,000 bends, so the adapter lives happily in a pocket, bag or car.
Keep your favourite wired headphones on a phone that has no headphone jack.

The built-in DAC is listed up to 32bit/384kHz and the charging path up to 60W. These are different paths: the 3.5mm port handles analog audio, while the female USB-C port accepts charging input only.
The defining functions of this SKU are separated from headline marketing so connector roles, power, data, length and battery limits remain clear.
Headline watts and gigabits are negotiated maximums, not universal results. Plan around every device, port, cable, charger, battery state and protocol in the path.
The DAC ceiling describes supported PCM conversion, not a promise that every phone, app, operating system or track will output 32bit/384kHz. The host audio stack, source file, application settings and connected analog equipment determine the actual format and audible result.
The charging path is pass-through. The adapter draws operating power and the receiving device negotiates with the external charger, so device-side power may be lower than the charger’s printed 60W or the adapter ceiling.
A 60W-capable USB-C charger and cable do not force 60W. Phones normally request far less; some laptops may require more than 60W or may not accept charging through an audio adapter.
Listening while charging can reveal noise from a poor-quality charger, earth loop, vehicle AUX system or sensitive earphones. Test audio without the charger, then add a standards-compliant charger to isolate the source.
The product page explicitly says no data transfer. The USB-C female port cannot connect storage, a keyboard, an Ethernet adapter or a monitor.
These practical examples keep the connector direction, supported protocol and safety limits in view.
Wired listening while charging. Connect 3.5mm headphones and an external USB-C charger so a compatible one-port phone or tablet can play audio and receive power together.
Calls and meetings. Use a compatible CTIA-style headset for calls or conferencing; verify microphone and inline-button behaviour before an important meeting.
Vehicle AUX connection. Feed analog audio to a vehicle 3.5mm AUX input while charging the USB-C phone. Keep cables clear of controls and troubleshoot any ground-loop noise.
Laptop or handheld audio. Add a 3.5mm output to a USB-C laptop or handheld that supports digital USB audio, while optionally feeding compatible USB-C charging power.
Use this sequence for a controlled first connection. Follow the connected-device maker’s stricter instruction whenever it differs.
A connector that fits is only the first check. The host, accessory, operating system and power source must support the requested function.
These are the supported functions of this product when the complete connection is compatible.
These exclusions distinguish this SKU from visually similar cables, chargers, hubs, audio products and power stations.
Choose by function: If the required task appears in this exclusion list, select a purpose-built cable, charger, adapter or power product with the needed interface and rating.
These habits support reliable charging, data, audio and battery use while reducing avoidable connector strain.
Avoid these common mistakes even when the plug appears to fit.
Review these electrical, thermal, transport and physical limits before connecting valuable equipment.
Stop and recheck: Disconnect power if a connection becomes loose, wet, damaged, swollen, unstable or unusually hot. Never keep reconnecting equipment that shows a safety warning.
Confirm connector direction, required protocol, power profile, cable length and package needs before choosing by appearance.
Disconnect power before inspection and change one variable at a time when diagnosing a connection.
Model specifications are consolidated below. Maximum values remain conditional on the complete negotiated connection.
Only components supported by the model record or an official model package list are included here. Scene devices and props are excluded.
It accepts charging input only and can pass negotiated power to the host up to 60W. It does not carry USB data, video or peripherals.
No. It is an audio adapter with a charging pass-through path. A separate compatible USB-C charger and cable are required.
No. this product specifically excludes data transfer through its USB-C charging port.
No. The female USB-C port is charging-only, so storage, hubs, Ethernet and keyboards are unsupported.
No. It does not support DisplayPort Alt Mode, HDMI, Thunderbolt or USB4 video.
It is the DAC’s maximum listed PCM decoding capability. The host, operating system, app, source audio and headphones determine the actual format.
It can with compatible USB-C iPhone models that support digital USB audio and charging through the adapter. Lightning-only iPhones do not connect directly.
It can with a compatible CTIA headset and host/app. Microphone and button behaviour must be tested on the combination.
Only if the charger, cable and device support the required profile. The device negotiates its input and the adapter itself has operating loss.
The charger, vehicle AUX ground, speaker power or sensitive earphones may introduce noise. Test audio without charging, then add a reputable charger and cable.
No. It is a physical design/coupling feature, not MagSafe, Qi or a wireless power path.
