Setup
Follow these steps to connect your Kircuit 24V AC/DC Adapter to your compatible UGREEN docking station:
- Identify the Power Input Port: Locate the DC power input port on your UGREEN Revodok Max 313 or Revodok Max 208 Thunderbolt 4 Docking Station. This is typically a circular barrel-type connector.
- Connect the Adapter: Insert the barrel connector of the Kircuit 24V AC/DC Adapter firmly into the DC power input port of the docking station.
- Plug into Power Outlet: Connect the AC power cord of the adapter to a standard electrical wall outlet. The adapter is designed for worldwide input voltage (100-240VAC, 50/60Hz).
- Verify Connection: Ensure all connections are secure. The docking station should now receive power.

Maintenance
Proper maintenance helps prolong the life of your adapter:
- Cleaning: Keep the adapter clean and dry. Use a soft, dry cloth to wipe off dust. Do not use liquid cleaners.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Cable Inspection: Periodically inspect the power cord and connector for any signs of damage, such as fraying, cuts, or bent pins. If damage is found, discontinue use and replace the adapter.
- Avoid Stress: Do not bend or crimp the cables excessively, especially near the connectors, as this can cause internal damage.
Troubleshooting
If you encounter issues with your adapter, refer to the following common problems and solutions:
- No Power to Docking Station:
- Ensure the adapter's barrel connector is fully inserted into the docking station.
- Verify the AC power cord is securely plugged into both the adapter and the wall outlet.
- Try plugging the adapter into a different wall outlet to rule out a faulty outlet.
- Check if the wall outlet is receiving power (e.g., by plugging in another device).
- Adapter Overheating:
- Ensure the adapter is placed in a well-ventilated area and not covered by objects.
- If the adapter feels excessively hot to the touch, unplug it immediately and allow it to cool down. Discontinue use if overheating persists.
- Docking Station Not Functioning Correctly:
- Confirm that your docking station model (UGREEN Revodok Max 313 U709 25085 or Revodok Max 208 U708 25053) is compatible with this 24V 5.83A 140W adapter.
- Ensure the docking station itself is not faulty. Test it with its original power supply if available.
If these steps do not resolve the issue, please contact customer support.
