Purpose and Audience

This USB-C adapter lets you charge a compatible phone and use 3.5 mm wired headphones at the same time. It is aimed at owners of LeTV Mole handsets that lack a dedicated audio jack. The 13 cm cable adds minimal bulk for daily carry.

Thermals Noise and Power

Passive circuitry draws power only from the host device and generates no audible noise. The aluminium shell helps dissipate the small amount of heat produced during simultaneous charging and audio playback. No external power supply or active cooling is required.

Build Integration

The reversible USB-C plug inserts either way and connects directly to the phone’s port. A single 3.5 mm socket accepts standard analogue headsets for calls and music. The short TPE-jacketed tail keeps the setup tidy without needing extra adapters or dongles.

Questions about this item

How do I plug the 13 cm cable into my phone so it charges and plays audio at the same time?

Insert the USB-C plug either way up — it is reversible — then connect your 3.5 mm headphones to the jack; the adapter handles charging and audio together.

What part of the 13 cm adapter is most likely to wear out first?

The TPE cable jacket and the aluminium shell protect the internal wiring, but repeated bending near the connectors can fatigue the cable over time.

How much power can the 13 cm cable pass through while I am listening to music?

The adapter supports standard USB-C charging currents for the connected phone, so charging speed matches the phone’s own limit during audio playback.
