This reliable adaptor allows you to connect to multi-gigabit speeds instantly, perfect for network intensive workloads.

Green technology that saves energy.
Power to the adapter is provided directly from the USB Type-C port and not only supports the USB 3.0 standard’s power-saving features, but also includes an energy-saving suspend and resume function to minimise power consumption when network traffic is light, the device is idle, or when the Ethernet cable is unplugged. Good for the environment, and ever better for your device’s battery life.
