Dual Function Adapter for USB-C Devices

This adapter connects 3.5mm headphones while simultaneously charging a USB-C device. It serves users whose phones or tablets lack a dedicated headphone jack but still want wired audio during charging.

Aluminium Shell and Integrated Audio Chip

The TPE and aluminium alloy housing protects the internal high-tech audio chip that handles both sound transmission and power delivery. This construction enables charging and listening at the same time without signal interference.

3.5mm Jack with USB-C Passthrough Charging

The single specification that determines compatibility is the combined 3.5mm audio output and USB-C charging input on one cable. Buyers whose devices require separate ports or proprietary audio protocols cannot use this adapter.

Questions about this item

Will the aluminium-alloy shell or the 3.5 mm jack wear out first?

The aluminium-alloy shell resists physical wear better than the 3.5 mm jack, which is rated for roughly 10 000 insertion cycles before contact degradation may appear.

What limits continuous use — the audio chip temperature or the pass-through charging current?

The pass-through charging path is the first limit; the adapter only forwards the host’s standard 5 V / 3 A profile, so sustained high-current charging will throttle before the audio chip reaches thermal limits.

How warm does the adapter get and does it add audible noise when charging and playing music all day?

The aluminium-alloy body stays near hand temperature during combined charging and playback, and the integrated audio chip introduces no measurable hiss or hum at the 3.5 mm output.
