  • 5 Gb/s wired speed for rapid NAS transfers and 4K/8K streaming
  • Realtek RTL8156BG chip runs 2.5 Gb/s at low power with reduced heat
  • Aluminium housing resists wear from repeated plug cycles
  • LED indicator shows link status at a glance
  • Works with Thunderbolt 4 and Thunderbolt 3 hosts

Aluminium 2.5Gb USB-C adapter

This aluminium adapter adds a 2.5Gb Ethernet port to any USB-C or Thunderbolt 4/3 device. It uses a Realtek RTL8156BG chip for low heat and stable throughput. The rugged housing resists repeated insertion and indicator lights show link status at a glance. Ideal for laptops, tablets and phones that lack built-in RJ45.

Suits 2.5Gb network upgrades

Buyers with 2.5Gb-capable switches or routers can immediately lift older 1Gb links to the higher rate without new cabling. The adapter draws little power so it runs cool during sustained transfers. Devices without a USB-C or Thunderbolt port cannot use it.

Realtek RTL8156BG controller

The single specification that decides fit is the Realtek RTL8156BG controller, which delivers 2.5Gb speeds over standard RJ45. If your switch, router or NAS only negotiates 1Gb the link will remain at 1Gb. No other chipset or speed is supported by this unit.

Questions about this item

Which version of the Vszerda USB-C to 2.5Gb Ethernet adapter should I choose for my setup?

This single model provides a 2.5Gb Ethernet port in an aluminium housing; there are no alternative capacities or versions listed, so choose this one if your router or switch supports 2.5Gb speeds.

What does the 2.5Gb figure mean once the adapter is connected to my laptop?

It indicates the maximum wired network throughput the Realtek RTL8156BG chip can deliver when paired with a 2.5Gb-capable router, switch or NAS, enabling faster large-file transfers and smoother 4K or 8K streaming.

What interface standard does the adapter use and what does it cap in practice?

The adapter uses a Thunderbolt-compatible USB-C connection; the practical ceiling is the 2.5Gb Ethernet link speed, limited by the RTL8156BG controller and the network equipment you attach.
