A USB-C dock is popular to many people for many benefits:
Expanded Connectivity: Most laptops, including Dell laptops, have a limited number of built-in ports. A USB-C docking station allows you to expand your laptop's connectivity options significantly.
Single Cable Solution: A USB-C docking station offers a convenient single-cable solution for connecting your laptop to multiple devices and peripherals, reducing cable clutter.
Multiple Monitor Support: Many USB-C docking stations like the Anker Prime Thunderbolt 5 Docking Station (14-in-1, 8K) support multiple monitor setups, allowing you to connect several external displays to your laptop to improve your productivity.
