This article covers サンワダイレクト Type-C ドッキングステーション HDMI 4K.

Overview

The Sanwa Direct Type-C Docking Station, model 400-DKM2BK, is an 8-in-1 mobile dock that connects to a laptop through a single USB-C cable. It provides HDMI output, wired LAN, SD card readers, and USB ports in one compact unit. The plastic body keeps the price accessible, positioning this as an entry-level model despite its eight ports.
Its compact size fits easily into a pouch or bag pocket, making it convenient for users who move between home and office. At the desk, one USB-C cable connects the laptop to an external display and peripherals; when leaving, simply unplug the cable and go. The HDMI port supports up to 4K/30Hz output via DP Alt Mode, and no driver installation is required.

Connectivity & Compatibility

The dock offers eight ports: HDMI×1, USB-C×1, USB-A×2, a PD charging-only Type-C port, SD card slot, microSD card slot, and wired LAN. The USB-A ports consist of one USB 2.0 and one USB 5Gbps port, while the USB-C port also supports 5Gbps data transfer.
USB PD charging is supported with up to 100W input and up to 85W output to the PC, so you can charge your laptop while working. The wired LAN port provides a stable network connection through the single USB-C cable. The built-in SD and microSD card readers make it easy to transfer photos and video files.
This dock works with laptops that have a USB-C port, and video output requires DP Alt Mode support. The plug-and-play design means no driver installation is needed, which helps in a wide range of environments.

Product Info

This is a Sanwa Direct product with model number 400-DKM2BK. It is sold as an entry-level model that combines eight functions in a simple plastic design at an affordable price. The warranty period is one year from the date of purchase.
In the market, this dock targets first-time docking station users and those looking for a portable secondary dock. It stands out by offering eight ports while keeping the price within reach of budget-conscious buyers.

Best Use Cases

  • Remote workers who dock a laptop daily: one cable handles display, network, and peripherals, and unplugging is all it takes to move to another location. Not ideal for users who never leave a fixed desk setup.
  • Frequent presenters who give slideshows at meetings or client sites: HDMI output supports up to 4K/30Hz, and the SD card reader makes sharing documents and photos straightforward.
  • Laptop users short on USB ports: two USB-A ports and one USB-C port accommodate a mouse, keyboard, and other accessories, while PD charging keeps the laptop powered during work.
