Hetai Tech USB C 2-in-1 Audio Charging Adapter 12cm

What this adapter does and who needs it

The Hetai Tech USB C 2-in-1 Audio Charging Adapter adds a 3.5 mm headphone jack and a charging port to phones that only have a USB-C socket. It is aimed at owners of listed models such as the Mi 6, Mi Note 3, LeTV 2nd and 3rd generation, Hammer Nut Pro, HTC U11 and HTC U Ultra who want to listen through wired headphones while the battery recharges. Buyers whose handset is not on the compatibility list should check before ordering.

The specification that decides fit

The connector is a reversible USB-C plug that carries both analogue audio for the 3.5 mm jack and up to 2 A of charging current. If your phone requires a digital audio dongle or does not support audio accessory mode over USB-C, this cable will not deliver sound. The aluminium-alloy and TPE body measures about 7 mm thick and the cable is 12 cm long.

Installation and common issues

Plug the USB-C end into the phone, connect headphones to the 3.5 mm socket and attach a charger to the second port; no drivers are needed. The short 12 cm tail can strain the phone's port if the handset is used while lying flat, and the 2 A charge rate may be slower than the phone's native fast-charging standard.
