Three-in-one USB-C adapter

The Vszerda UC-155-TC004 adds a 3.5mm audio jack and a USB 2.0 Type-A port to laptops, tablets or phones that only have USB-C. It also passes through up to 15W of PD charging so the host device stays powered while peripherals are in use.

Thermals noise and power

The copper construction and passive design produce no fan noise and negligible heat during typical audio playback or data transfer. Power draw is limited to the 15W PD pass-through rating and the 480Mbps USB 2.0 bus limit.

Build integration

The compact white dongle plugs directly into a USB-C port without blocking adjacent sockets on most devices. It frees the single port for simultaneous wired audio, legacy USB-A accessories and charging, removing the need for separate hubs or splitters.

Questions about this item

How do I plug the UC-155-TC004 into my laptop and start using the 3.5 mm jack and USB 2.0 port?

Insert the USB-C male plug into the host port; the adapter draws power from the host, so no external supply is needed for audio or data — only attach a PD charger to the adapter's USB-C port if you want up to 15 W pass-through charging while using the other ports.

Will the copper conductors or the USB-C receptacle wear out and need replacement?

The adapter has no moving parts or batteries; the copper wiring and USB-C connectors are rated for normal insertions, so no scheduled maintenance or user-replaceable components are required.

At what point does the 480 Mbps USB 2.0 link become the bottleneck during a long file transfer?

Sustained transfers are capped at the USB 2.0 maximum of 480 Mbps, so any single large file or continuous stream will hit that ceiling first, regardless of the host's USB 3.1 capability.
