Hi there!
Different countries use different power plug standards.
Power cords are NOT included by default.
Package Includes:
1 × Docking Station
1 × 130W Power Adapter (AC power cord is not included)
1 × Data Cable (Cable style may vary slightly by batch, all fully compatible and work perfectly with the dock)
Regarding external display connectivity:
On Mac computers, the DisplayPort of this dock only supports 4K @ 60Hz. The downstream Thunderbolt Type-C port can run at 4K @ 144Hz. This is suspected to be caused by poor DSC compatibility.
On Windows and other systems, if the host PC natively supports DSC, the dock’s DisplayPort can output 4K @ 144Hz, and the Thunderbolt Type-C port also works at 4K @ 144Hz. Due to bandwidth limitations, it should not be able to support two 4K 144Hz frequencies simultaneously.
