SKU CH-QJ5C-ZA9S0

A 20 V AC adapter with a 10 ft cord, 100–240 V input, and FCC, CE, RoHS certification for the UtechSmart D6919 docking station

  • World-wide 100-240 V input works anywhere
  • 10 ft power cord gives flexible placement
  • Over-current, over-voltage and short-circuit protection
  • FCC, CE and RoHS certified for safety
  • 100 % compatible replacement for UtechSmart D6919

What this adapter powers

This 20 V AC adapter replaces the original supply for the UtechSmart D6919 docking station. It delivers the voltage and current that the dock requires to run three external monitors at 4K 60 Hz over Thunderbolt 3 or 4 on Windows systems. The unit is sold new and is fully compatible with the specified model.

Build quality and daily use

The adapter includes a 10 ft power cord, giving flexibility for desk or floor routing. Safety circuitry provides over-current, over-voltage, short-circuit and total-power protection, while a smart chip adds over-heating and over-charge/discharge safeguards. Anti-interference isolation materials and high-quality wiring are used throughout. Certifications cover FCC, CE and RoHS.

Limits of the 20 V standard

The supply operates on 100-240 VAC at 50 or 60 Hz, so it works worldwide without a voltage converter. It is designed only for the D6919 dock; it will not power devices that require a different voltage or connector. Buyers who need a second adapter for another dock model or a higher-wattage unit for a laptop should look elsewhere.

Questions about this item

Does the 20 V AC adapter use a Thunderbolt connection to power the UtechSmart D6919 docking station?

No, the 20 V AC adapter supplies power through a standard DC barrel connector; the Thunderbolt 3/4 link on the D6919 handles video and data only.

What physical clearance does the adapter and its 10 ft cord need on a desk?

The brick itself is compact, but the 10 ft total cord length requires enough slack to reach a wall outlet without tension on the DC jack.

Which step do installers often skip when connecting the adapter to the D6919?

Plug the AC cord into the adapter brick first, then into a 100-240 VAC outlet, and only then insert the DC plug firmly into the dock's power port.
