Replacement adapter for Anker 777 docking station

This WAWEIS AC adapter supplies 22V at 5.45A and is built as a direct replacement for the Anker 777 A8397 Thunderbolt 4 docking station. It accepts a worldwide input range of 100-240VAC at 50/60Hz so it can be used in multiple regions. The unit carries FCC, CE and RoHS certifications and includes multiple safety protections. It is intended for owners who need a spare or replacement power supply for that specific dock.

Installation notes and common issues

Connection is straightforward: plug the IEC mains lead into the adapter and the barrel connector into the dock’s power input. The total cord length is 10 ft, giving flexibility for desk routing. Built-in protections cover over-current, over-voltage, short-circuit and total power events, which helps prevent damage from mains irregularities. Buyers who need a different voltage or a higher current rating for another device cannot use this adapter.

Limits of the Thunderbolt dock power interface

The adapter is rated to deliver 22V at 5.45A, which matches the original specification for the Anker 777 dock. It cannot supply more current than 5.45A, so docks or devices that draw a higher load will not operate correctly. The fixed output voltage means it is not suitable for hardware requiring a different DC level. Users should verify that their dock matches the listed model before connecting.

Questions about this item

How can I confirm the adapter is delivering the correct 22V 5.45A output to the Anker 777 A8397 dock after connecting it?

The dock should power on and charge connected devices normally; the adapter includes over-current, over-voltage, short-circuit and total-power protection that engage automatically if output deviates from specification.

What comes in the box with this WAWEIS replacement adapter and is there anything else I need to purchase separately?

The package includes the 22V 5.45A power supply with an integrated 10 ft AC cord; no extra cables or parts are required to operate the Anker 777 A8397 Thunderbolt 4 dock.

Which version of this adapter matches the Anker 777 A8397 Apex 12-in-1 Thunderbolt 4 Docking Station?

Choose the model rated 22V 5.45A (S120FO2200545) with 100-240VAC 50/60Hz input — it is the only variant listed as fully compatible with that dock.
