Final answer:
Docking stations are more feature-rich than port replicators, usually including their own power supply, additional video outputs, extra ports, options for additional storage devices, and security features which are not commonly found on port replicators.
Step-by-step explanation:
When it comes to the features that most docking stations will have that most port replicators don't, it boils down to a few key differences. Docking stations generally include additional functionality such as their own power supply, and additional video outputs, and might even have extra ports beyond what the laptop offers. On the other hand, port replicators tend to be simpler devices designed mainly to duplicate the existing ports on the laptop without adding substantial new features. Furthermore, docking stations can also include features like drive bays for additional storage devices, and built-in security locking mechanisms, and are typically designed to have a more robust and heavier construction to securely hold the laptop in place.
