What is the difference between a USB-C hub and a Thunderbolt dock?

USB-C hubs share 10Gbps bandwidth across all ports and typically cost $30-80. Thunderbolt 4 docks provide 40Gbps dedicated bandwidth, support higher-resolution displays, and charge laptops at higher wattages, typically costing $150-400.

Do I need Thunderbolt 4 for my dock?

If you use dual 4K monitors or higher, transfer large files to external SSDs, and want single-cable laptop charging, Thunderbolt 4 is worth the investment. For basic display extension and USB peripherals, a USB-C hub is sufficient.

Can I charge my laptop through a docking station?

Yes. Most docks and hubs offer USB-C Power Delivery pass-through. Thunderbolt 4 docks typically deliver 85-130W, enough to charge most professional laptops. Check that the dock's PD wattage matches your laptop's charger.

How many monitors can I connect through a dock?

USB-C hubs typically support 1-2 monitors at 4K 30Hz. Thunderbolt 4 docks support dual 4K 60Hz or single 8K. The Plugable UD-4VPD uniquely supports quad 4K 60Hz displays.

Do docks work with Mac and Windows?

Yes. All docks in this guide are compatible with both macOS and Windows. However, Apple Silicon Macs have specific display output limitations that may restrict dual-display functionality with some docks.

What is 2.5 Gigabit Ethernet?

2.5GbE provides 2.5x the speed of standard Gigabit Ethernet (312 MB/s vs 125 MB/s). Useful for NAS storage, large file transfers, and offices with multi-gigabit network infrastructure.

Is the CalDigit TS4 worth $379?

For professionals who need maximum port density, dual 6K display support, and 2.5GbE, yes. The TS4 replaces 3-4 separate adapters with one device. For basic dual-monitor setups, the Kensington SD5780T at $249 is sufficient.

Can I use a Thunderbolt dock with a USB-C only laptop?

Thunderbolt 4 docks require a Thunderbolt 4 host port. Connecting to a standard USB-C port limits functionality to USB speeds and may not support display output or power delivery at full capacity.
