SKU CH-R2BJ-0RZVC MPN HB31CM4CPD3

Four USB 3.2 Gen 2 Type-C ports at 10 Gbps with 100 W PD pass-through for laptop charging and peripheral power

  • Product typeInternal USB Hub
  • Add four 10 Gbps USB-C ports to a single USB-C or Thunderbolt connection
  • Charge a laptop up to 85 W while using three peripherals via 100 W PD pass-through
  • Hub draws 15 W for itself leaving up to 7.5 W per downstream port
  • Fast Role Swap on PD 3.0 keeps data flowing when power source changes
  • Lightweight bus-powered design works without an external adapter

Four USB-C ports at 10 Gbps

This StarTech hub turns a single USB-C or Thunderbolt 3/4 port into four USB 3.2 Gen 2 Type-C ports running at 10 Gbps. It is aimed at laptop users who need more high-speed connections for external SSDs, docks or video-capture devices. The unit draws power from the host but can also accept a USB-C PD adapter to charge the laptop while peripherals stay connected.

For users who need four 10 Gbps Type-C ports

Suits anyone whose laptop has only one USB-C or Thunderbolt 3/4 port and wants to attach several fast peripherals at once. Not for buyers who need Type-A ports, video outputs such as HDMI or DisplayPort, an Ethernet jack, or SD-card slots. Also not for setups that require more than 85 W of pass-through charging power for the host.

100 W PD pass-through with 85 W host share

The hub reserves 15 W for its own operation and delivers up to 85 W to the laptop and downstream devices when a USB-C PD 3.0 power adapter is connected. Fast Role Swap prevents data interruption when switching between bus power and the external adapter. Without an adapter the hub runs on bus power alone.

Questions about this item

Does the hub come with a power adapter for the 100W PD pass-through?

No, a USB-C power adapter is not included; the hub works on bus power alone or you can connect your own USB-C charger to the PD port to enable up to 100W pass-through.

When should I use the PD port instead of running on bus power?

Connect a USB-C charger when you need to charge the host laptop and supply up to 7.5W to each of the three remaining ports; bus power alone cannot charge the laptop.

What does the 10Gbps rating mean for devices I plug in?

Each of the four USB 3.2 Gen 2 Type-C ports can transfer data at up to 10Gbps, so high-bandwidth peripherals such as fast SSDs or docks run at their full rated speed.
