Dual-laptop KVM for two monitors
The SMA C212H lets two laptops share a pair of displays and four USB 3.0 peripherals through a single USB-C connection per computer. It supports video up to 4K at 60 Hz and 2K at 144 Hz or 120 Hz, with automatic fallback to lower resolutions. A wired remote and all necessary cables are included for immediate setup.
Sustained operation with 80 W power delivery
The unit draws operating power from the attached laptops and requires no separate supply, while its USB-C PD port delivers up to 80 W to keep a host charged during long sessions. USB 3.0 ports maintain 5 Gbps throughput for storage or input devices without throttling, and the switch remains stable when left running continuously.
Compact metal enclosure with front switching
The housing measures 3.94 by 2.76 by .79 inches and fits unobtrusively on a desk, with push-button and remote switching for quick host changes. Three USB-A ports and one USB-C port on the front provide easy access for keyboards, mice, drives or printers. Note that macOS limits output to mirror mode only, so extended desktops are not possible on Mac systems.

Questions about this item
Does the 80W PD charging port generate noticeable heat when both laptops stay connected all day?
The unit draws power from the 80W PD port to run the switch and charge the active laptop; it has no fan and relies on its metal casing for passive cooling, so it stays warm but not hot during continuous use.
What type of USB-C port must each laptop already have for video, data and 80W charging to work through the C212H?
Each laptop needs a full-featured USB-C port that supports DisplayPort Alt Mode for video, USB 3.0 data and Power Delivery up to 80W; a USB-C port that is data-only or charging-only will not drive the dual 4K@60Hz outputs.
Will a Windows laptop running MST and a MacBook running SST share the two monitors without re-cabling when I switch between them?
Yes — the switch passes whatever signal the active laptop sends; Windows can drive two independent 4K@60Hz streams via MST while macOS mirrors the same image on both screens via SST, and the front push-button swaps sources instantly.
