Hetai Tech 2-in-1 USB-C to 3.5 mm audio & charging cable

SKU CH-QCTT-FX4JE

A 2-in-1 adapter adds a 3.5 mm audio jack and charging port to USB-C devices lacking a headphone socket

  • Connector TypeMicro USB to USB A
  • Enjoy music while charging via single USB-C port
  • 5 mm jack works with existing headphones instantly
  • Plug-and-play design needs no drivers or setup
  • Metal-and-plastic build resists wear for long service life
  • Lightweight cable slips into pocket or bag easily

What it is and who it's for

This Hetai Tech adapter connects a 3.5 mm headphone plug and a USB-C charging cable to a single USB-C port on smartphones that lack a headphone jack. It works immediately without driver installation and lets you listen to audio while the device charges. The compact metal-and-plastic build is light enough to carry in a pocket or bag.

Thermals noise and power draw

Passive circuitry means the adapter generates no audible noise and adds no measurable heat during normal use. It draws only the tiny current needed for the audio signal path while the USB-C port negotiates the phone's standard charging rate. No fan, no active components, no thermal throttling concerns.

What it replaces and when to upgrade

This cable replaces the need to carry a separate USB-C to 3.5 mm dongle and a dedicated charging cable when you want wired audio and power at the same time. The jump is worth it if you regularly listen through wired headphones while charging and want one lightweight accessory instead of two. It does not serve devices that require volume controls on the cable or that use a Micro USB port for charging.

Questions about this item

How do I connect the 3.5 mm headphone plug and USB-C charging cable in the right order?

Insert the 3.5 mm headphone plug into the adapter first, then connect the USB-C end to your device for simultaneous audio and charging.

What part of the 3.5 mm audio jack or USB-C connector is most likely to wear out first?

The 3.5 mm jack and USB-C plug are built with metal housings and painted contacts for durability, so no specific component is singled out for early replacement.

At what point does the USB-C charging current limit performance during long listening sessions?

The USB-C interface supports a higher current level to speed up charging, but no maximum amperage or thermal threshold is specified for sustained use.
