Build a cleaner, faster, more capable workstation with the AV Access KD-S03 — a premium 12-in-1 USB-C dock designed for multi-display productivity, ultra-fast data transfer, wired networking, and full-power laptop charging through one streamlined connection
One Dock. A Complete Workstation.
AV Access KD-S03 is a premium 12-in-1 USB-C docking station built for users who need more screens, more ports, and more speed from a single laptop connection. Designed for modern workstations, it transforms a USB-C, USB4, or Thunderbolt 4 laptop into a complete desktop-style setup with display expansion, fast data transfer, wired networking, charging, audio, and card access in one refined hub.
Its biggest advantage is productivity. The KD-S03 is designed to support up to three displays, making it ideal for multitasking, creative work, analysis, coding, operations, and hybrid office setups. AV Access positions it for triple extended display on Windows, while macOS display behavior remains subject to Apple’s system limitations. For high-quality visual output, it supports configurations including dual 4K@60Hz and additional display expansion depending on the connected host and mode.
Beyond display flexibility, this dock is built for serious everyday performance. It supports 100W laptop charging, USB 3.2 Gen 2 data up to 10Gbps, 1GbE wired Ethernet, and SD/TF card reading, helping you connect storage, accessories, networks, and content workflows without juggling multiple adapters. It is also described by AV Access as compatible with Thunderbolt 4 and USB4 computers.
