Universal USB-C Audio & Charge Cable

This 12 cm adapter adds a 3.5 mm headphone jack and simultaneous charging to USB-C smartphones. It suits owners of devices such as the Xiaomi Mi 6, Mi Note 3, LeTV 2 and 3, Smartisan Nut Pro, HTC U11 and U Ultra that lack a built-in analogue port. The reversible Type-C plug inserts either way up for quick connection.

Passive Design with 2 A Charge Support

The cable draws power from the host port to deliver up to 2 A charging current while audio plays, so the battery replenishes during listening sessions. No active electronics or external power supply are involved, meaning no fan noise or additional heat beyond normal phone operation. The aluminium-alloy shell and TPE jacket dissipate warmth from the connectors.

Plug-and-Play Simplicity

No driver installation or companion app is required; the adapter works immediately on the listed handsets. Its 7 mm slim profile and 10.9 g weight keep pocket bulk minimal, and the 12 cm length avoids cable tangle at a desk or in a bag. The package includes only the adapter itself, leaving software EQ or DAC settings to the phone’s own audio menu.

Questions about this item

How do I connect the 3.5 mm plug and the USB-C end so charging works while I listen?

Insert the USB-C connector into the phone with the reversible side facing up, then plug the 3.5 mm jack into your headphones; the cable draws 2 A for charging while passing audio simultaneously.

What part of this 12 cm cable is most likely to wear out first?

The TPE jacket near the aluminium alloy housings and the 3.5 mm plug see the most flex stress, so inspect those points regularly for cracking.

At what point does the 2 A charge current become the limiting factor during long sessions?

When the phone requests more than 2 A the cable caps the flow, so charging slows while audio continues uninterrupted.
