Create a mobile workstation wherever you work

Transform a single USB-C port into a mobile workstation with 4K 60Hz HDMI, 140W USB-C PD passthrough, USB-C and USB-A connectivity, and integrated SD/microSD card readers, with ports on both sides for easier access and a 8-inch (20.3cm) braided tethered cable for flexible, durable use in shared workspaces and travel setups.

Keep High-Performance Systems Powered

Support demanding workflows with up to 140W USB-C Power Delivery passthrough. Keep AI-ready laptops, mobile workstations, and power-hungry systems running at full capacity while maintaining display and peripheral connectivity through one compact adapter.

Connect More Devices Without Giving Up Ports

Add three USB 10Gbps ports for high-speed storage and accessories, plus a USB 2.0 port for keyboards, mice, or other essential peripherals. Ideal for thin laptops, 2-in-1s, and MacBooks where port availability is limited.

Easy Card Access Anywhere

Integrated SD and microSD 4.0 card readers support simultaneous file transfers to streamline media handling across cameras, mobile devices, and external storage. Eliminate extra adapters and reduce setup time for content creation, field work, and mobile IT environments.
