SKU CH-A64E-1BEZ4

  • World-wide 100-240 V input works anywhere
  • 10 ft cord reaches distant outlets easily
  • Over-current, over-voltage and short-circuit protection
  • FCC, CE and RoHS certified for safety
  • 125 W output powers Thunderbolt 3 dock reliably

Replacement Adapter for Thunderbolt 3 Dock

This WAWEIS AC adapter replaces the original power supply for Belkin F4U109 Thunderbolt 3 Dock models. It delivers 20V at 6.25A for 125W output, matching the dock's required input. The unit is new and built with 100% new components.

Upgrading from a Lost or Damaged Unit

The adapter serves as a direct replacement when the factory charger is lost, damaged or no longer holds a stable voltage. It supports a 19.0V to 20.0V range and handles up to 6.75A for 135W peak capacity. The jump is worth it when downtime costs more than a spare unit.

Limits of the 100-240VAC Input Standard

The power supply accepts world-wide input voltage from 100VAC to 240VAC at 50Hz or 60Hz. A 10 ft power cord provides reach, but the brick itself is sized for the dock's 125W to 135W envelope. It cannot power devices that demand higher wattage or a different voltage rail.
