Quick guide from the manual

The Techly USB-C 12-in-1 Docking Station is a multifunctional hub designed to expand connectivity for computers, tablets, and mobile phones. Key requirements for full functionality include:

  • Charging: Your device must support Power Delivery (PD) or Thunderbolt 3/4.
  • Video Output: Your laptop must support DP ALT mode on the USB-C port.
  • MST (Multi-Stream Transport): Functionality depends on your graphics card, operating system, and monitor. Use only passive VGA/HDMI cables (without chipset/signal converter).
  • Simultaneous Use: SD and TF cards cannot be used at the same time.

  2. Connect the docking station to the computer's USB-C port; it will be automatically recognized (Plug-and-Play).
  3. Connect your peripherals to the docking station ports one by one.
  4. For stable operation, especially when reading large capacity hard disks, connect a charger to the PD port.
  5. Note: If the charger is disconnected during use, connected devices may temporarily disconnect.
  6. When using HDMI and VGA simultaneously, the resolution for both is limited to 1080p.

Safety Indications

To ensure safe operation, please observe the following:

  • Keep the device away from children as it contains small parts.
  • Avoid environments with high temperatures, humidity, water, dust, or smoke.
  • Do not install near air conditioner openings or in areas subject to vibration.
  • Do not modify the product or use damaged parts.
  • Ensure sufficient space around the device for ventilation.

Practical help

Common problems

SD and TF cards not working together

The device does not support simultaneous use of SD and TF cards; use them one at a time.

Video output not working

Ensure your laptop's USB-C port supports DP ALT mode.

Device disconnects during use

Ensure the power charger is connected to the PD port, especially when using high-power peripherals or hard disks.

Resolution is lower than expected when using multiple monitors

When connecting two video output interfaces simultaneously, the resolution is capped at 1080p for both.

Before use

  • Verify your laptop supports DP ALT mode on the USB-C port.
  • Ensure your device supports Power Delivery (PD) or Thunderbolt 3/4 for charging.
  • Use passive VGA/HDMI cables without chipsets for MST functionality.
  • Connect the power charger to the PD port for optimal performance.
  • Check that your graphics card and OS support MST for multi-monitor setups.
