An 8-in-1 USB-C hub adding dual HDMI displays up to 8K at 30 Hz or 4K at 60 Hz, three USB 3.1 ports, dual SD and microSD card slots and 100 W pass-through charging

  • 100 W pass-through charging keeps your laptop powered
  • Dual HDMI outputs drive two 4K displays at 60 Hz
  • Three USB 3.1 ports deliver 5 Gbps data speeds
  • Built-in SD and microSD slots read both cards at once
  • DisplayPort 1.4 Alt mode enables 8K video at 30 Hz

Connectivity for Type-C devices

This 8-in-1 hub adds two HDMI outputs, three USB-A ports, dual SD and microSD card slots and a USB-C pass-through to laptops and tablets equipped with a single USB-C or Thunderbolt 3 or 4 port. It is designed for professionals who need multiple displays, legacy peripherals and card readers from one compact adapter.

Build integration and port expansion

The adapter draws power from the host USB-C connection and delivers up to 100 W pass-through charging so the host stays powered while all ports are active. Two HDMI ports free the user from a single internal display, three USB-A ports accommodate existing keyboards, mice or drives, and the dual card slots allow simultaneous SD and microSD access without extra dongles.

Thermals, noise and power draw

The unit has no moving parts and operates silently, with heat dissipated through the aluminium housing during normal multi-display and data-transfer workloads. Host power delivery of up to 100 W is negotiated over USB-C, and the hub itself consumes only the overhead required for DisplayPort 1.4 Alt mode video and USB 3.1 5 Gbps data signalling.

How much heat or fan noise does the 100 W power delivery generate during continuous charging?

The aluminium enclosure passively dissipates the 100 W charging load with no fan and stays warm but not hot.
