👎 Cons
- The 135W Slim Tip power adapter adds bulk to the desk setup and is not USB-C based
- 100W power delivery may be insufficient for high-performance workstation laptops that draw more under load
- No SD or microSD card reader built into the dock, requiring an external adapter for media workflows
- HDMI 2.1 port is limited to a single connection, so multi-monitor setups rely primarily on DisplayPort
