Black rectangular AC adapter with 10 ft power cord

WAWEIS

WAWEIS 20V 6.75A 135W AC Adapter for Plugable TBT3-UDZ UDV

SKU CH-C4W0-6AAVP

A 135 W, 20 V / 6.75 A replacement charger with a 10 ft cord, worldwide 100-240 V input and FCC, CE, RoHS certification

  • World-wide 100-240 VAC input for travel flexibility
  • 135 W output at 20 V 6.75 A matches original specs
  • 10 ft total cord length gives extra reach
  • FCC CE RoHS certified with multiple safety protections
  • 12-month warranty on all-new components

Direct Replacement for Plugable Thunderbolt Docks

The WAWEIS 20V 6.75A 135W AC adapter is built as a direct replacement for Plugable TBT3-UDZ and TBT3-UDV Thunderbolt docks. It matches the original 20VDC 6.75A 135W specification so the dock can deliver full power to connected laptops and peripherals. The unit ships new with a total 10 Ft long power cord for flexible desk placement. It carries FCC, CE and RoHS certifications.

Thermal Protection and Efficient Power Delivery

The adapter includes over current protection, total power protection, over voltage protection and short circuit protection to guard both the dock and attached devices. An internal smart chip provides overheating protection during sustained loads. High quality wires and better isolation materials add anti-interference performance. World wide input voltage 100-240VAC 50/60Hz allows use across regions without a voltage converter.

Upgrade from Lost or Failing Original Chargers

This unit replaces a missing, damaged or out-of-specification original charger that can no longer sustain 135W output. The jump is worth it when the dock throttles connected laptops, drops video outputs or resets under load because the old adapter cannot maintain voltage. It is not for buyers who need a higher wattage unit for newer docks requiring more than 135W, or for docks with a different voltage or connector polarity.

Questions about this item

How do I connect the adapter to the Plugable TBT3-UDZ dock and what is the step people often miss?

Plug the barrel connector firmly into the dock's DC input until it seats, then connect the 10 ft power cord to a 100-240VAC 50/60Hz outlet. The step people miss is verifying the dock's LED confirms 20V 6.75A 135W delivery before attaching Thunderbolt devices.

What maintenance or replacement will this adapter need over time?

The 10 ft cord and barrel plug are the only wear items; inspect them periodically for fraying or loose fit. The internal smart-chip protections (over-current, over-voltage, short-circuit, overheat) are non-serviceable — if any trips permanently, replace the entire unit.

What limit appears first when the adapter runs at full 135W load for long periods?

Thermal protection activates first; the smart chip will throttle or shut off output if internal temperature exceeds safe limits, so keep ventilation clear around the brick during sustained 20V 6.75A operation.
