SKU CH-76K3-5K2FH MPN HB31C3A1CME

Four-port metal hub adds 10 Gbps USB-C connectivity and Thunderbolt 3 compatibility to laptops and desktops

  • TypeInternal USB Hub
  • ColorBlack
  • 10 Gbps data transfer across four USB ports
  • Metal housing protects internal components
  • Works with Thunderbolt 3 host ports
  • Backward compatible with earlier USB devices
  • Compact design fits tight workspaces

Portable connectivity for thin-and-light devices

This four-port hub adds high-speed USB-A connections to laptops and tablets that only offer USB-C or Thunderbolt 3 ports. It targets mobile professionals and hot-desk workers who need legacy peripherals without carrying multiple dongles. The metal enclosure withstands daily transport in a bag.

10 Gbps aggregate bandwidth across four USB-A ports

The single upstream USB-C link delivers up to 10 Gbps shared among all downstream ports, so simultaneous transfers from multiple SSDs will divide that ceiling. Buyers who need sustained 10 Gbps per device should consider a multi-controller solution instead.

Bus-powered design requires no external adapter

The hub draws operating power directly from the host USB-C or Thunderbolt 3 port, leaving wall outlets free and keeping cable count low. It adds no software layer and works with any OS that supports standard USB mass-storage and HID classes.

Questions about this item

What does the 10Gbps rating mean when the hub is plugged into my laptop?

It means each of the four ports can move data at up to 10 gigabits per second, so large files transfer quickly when the host port also supports that speed.

Which interface standard does the hub use, and what does it limit?

The hub connects through a USB-C port that is also compatible with Thunderbolt 3, so the 10Gbps ceiling applies whenever the host controller allows it.

What physical space or mounting does the metal hub need?

The compact metal casing sits on a desk or travels in a bag; no brackets or screws are required for installation.
