The j5create JCD403 USB4 8K Multi-Port Hub is a USB Type-C hub that combines a USB4 controller with compatibility for Thunderbolt 4 and earlier USB standards. It supports up to 40 Gbps total throughput with dynamic allocation of data and display bandwidth, enabling connection of high-definition monitors with resolutions up to 8K (7680 x 4320). The hub includes HDMI, RJ-45 Ethernet, one USB-C SuperSpeed+ 10 Gbps port, two USB-A SuperSpeed+ 10 Gbps ports, and a USB-C Power Delivery pass-through port that supplies up to 100 W to charge a connected laptop while powering peripherals.

Advantages

The hub delivers high aggregate bandwidth (up to 40 Gbps) suitable for demanding display and data tasks while remaining backward compatible with older USB and Thunderbolt 4 devices. With dedicated SuperSpeed+ 10 Gbps ports and a 100 W USB-C Power Delivery passthrough, it supports fast data transfers, external device connectivity, and laptop charging through a single USB Type-C connection. Its compact grey enclosure provides multiple interfaces—HDMI, RJ-45, USB-A and USB-C—reducing the need for separate adapters.

Suitable for

• Connecting one or more high-resolution external monitors (up to 8K)
• Expanding laptop ports for peripherals such as external drives, keyboards and mice
• Providing wired network access via RJ-45 Ethernet
• Charging a laptop while using multiple USB devices (up to 100 W pass-through)

How to use

Connect the hub to a host computer via the USB Type-C (USB4) host cable. Use the HDMI port to attach an external monitor, and configure display settings on the host operating system as needed. Plug network cable into the RJ-45 port for wired LAN access. Attach peripherals to the USB-A or USB-C SuperSpeed+ ports for data and charging. If charging the laptop, connect a USB-C PD power adapter to the hub’s USB-C Power Delivery port to provide up to 100 W pass-through power to the host.

Recommendations

For optimal display performance when using high resolutions (4K/8K) and multiple peripherals, use a host system and cables that fully support USB4 or Thunderbolt 4 and connect a high-wattage USB-C PD adapter (up to 100 W) to the hub’s power input.
