Silver rectangular dock with multiple ports on both sides

Kensington

Kensington AD220S3 12-in-1 Triple Video Dock 85W

SKU CH-2A3F-4GCAK MPN AD220S3

Connects up to three external displays, adds five USB ports, card readers and gigabit Ethernet while delivering 85W pass-through charging for MacBooks and USB-C laptops

  • Triple-video support for MacBook M1, M2 and M3 via Silicon Motion driver
  • 85 W pass-through charging keeps laptop powered while docked
  • 12-in-1 connectivity includes 5 USB ports, 3 video outputs, card readers and Gigabit Ethernet
  • Professional aluminium design matches modern MacBook Air and Pro workstations
  • Works with Thunderbolt 4, USB4 and USB-C Alt Mode laptops on Windows 10+ or macOS 11+

Universal USB-C docking station

The Kensington AD220S3 adds twelve ports through a single USB-C connection and supports any MacBook with M1, M2 or M3 silicon plus Thunderbolt 4, USB4 or USB-C Alt Mode laptops running Windows 10 or macOS 11 and above. A Silicon Motion driver enables dual or triple external displays on Apple silicon that normally limits external outputs. The compact aluminium chassis matches modern workstation aesthetics while remaining portable for travelling professionals.

Replaces single-port dongles

Instead of juggling separate video adapters, card readers and power bricks, this dock consolidates everything into one device. The upgrade is worthwhile when you regularly connect two or three monitors, need wired Ethernet and want to keep the laptop charged without a second cable. If you only ever use one external screen and have enough native ports, the extra connectivity will sit idle.

Triple video and peripheral headroom

Two HDMI ports and one VGA port drive up to three displays simultaneously while five USB ports handle peripherals at 5 Gbps. The UHS-I SD and microSD reader transfers media cards and the Gigabit Ethernet jack provides wired networking. Pass-through charging delivers up to 85 W to the laptop; a 100 W adapter is recommended when high-draw devices such as external SSDs are attached. Without that larger adapter the dock will draw from the laptop battery under heavy load.
