- Prices typically range from $15 to $75.
USB-C docks: creating a powerful desktop workspace
USB-C docks offer a comprehensive solution for creating a fully-fledged desktop setup from a laptop. They provide significantly more ports than hubs, including multiple video outputs (HDMI, DisplayPort, and even Thunderbolt), multiple USB ports (USB-A and USB-C), Ethernet for a stable wired network connection, and audio in/out jacks. High-end docks can even support up to 100W of power delivery, enabling charging of power-hungry laptops while simultaneously supplying power to other connected devices. Docks are available in portable and desktop configurations, offering a balance between portability and functionality.
- Support multiple high-resolution video outputs, commonly up to 4K or 8K
- Offer robust power delivery (often 60W or more) for charging and powering peripherals.
- Include a wide array of ports, including USB-A, USB-C, HDMI, DisplayPort, Ethernet, and audio jacks.
- Prices range from $50 to over $200, depending on features and capabilities.
USB-C adapters: simple solutions for specific needs
USB-C adapters provide a straightforward solution for connecting a single device to your USB-C port. For example, a USB-C to HDMI adapter allows you to connect to an external display, while a USB-C to Ethernet adapter provides a wired network connection. These adapters are cost-effective and ideal for users with specific, limited connectivity needs. Their simplicity is their strength, but they generally lack the power delivery and multiple-port functionality of hubs and docks.
- Affordable and easy to use
- Ideal for single-device connections (e.g., HDMI, Ethernet, USB-A)
- Typically do not offer power delivery capabilities
- Prices usually range from $10 to $30
