Replacement AC adapter for Plugable UD-ULTC4K dock

This 20V 6.75A power supply replaces the original Chicony A18-135P1B unit for the Plugable UD-ULTC4K triple-display docking station. It delivers 135W output with worldwide 100-240VAC 50/60Hz input compatibility. The adapter is built with new components and carries FCC, CE and RoHS certifications. It targets users who need a direct replacement for a lost or damaged dock charger.

Thermal and electrical behaviour

Safety circuitry includes over-current protection, over-voltage protection, short-circuit protection and total power protection. An internal smart chip manages overheating protection during operation. High-quality wires and isolation materials provide anti-interference performance. The unit runs on standard mains voltage without requiring a separate voltage selector.

Included power cord and compatibility

A 10 ft power cord is integrated, giving flexible placement for the docking station. The adapter is 100% OEM compatible with the specified Plugable model and the Chicony A135A023P part. It is not suitable for devices requiring a different voltage, current or connector type. Buyers needing a higher wattage unit or a USB-C PD charger for direct laptop charging should look elsewhere.

Questions about this item

How do I install the WAWEIS 20V 6.75A adapter with the Plugable UD-ULTC4K dock, and what step is often missed?

Connect the DC plug to the dock's power input, then plug the AC cord into a 100-240VAC 50/60Hz outlet. The step often missed is ensuring the 10 ft cord is fully unwound to prevent overheating during sustained use.

What maintenance or replacement will this adapter need over time?

The adapter has no user-serviceable parts. Replace the unit if the smart chip triggers overheating protection repeatedly, or if the 10 ft cord shows insulation damage. FCC, CE and RoHS certified components are rated for long-term 20VDC 6.75A output.

What limit appears first when the adapter runs at full 135W load continuously?

The over-current and over-voltage protection circuits activate first if sustained draw exceeds 6.75A at 20V. The smart chip also enforces overheating protection, throttling output before total power protection shuts the unit down.
