Frequently Asked Questions
What is the best Thunderbolt 4 dock?
The CalDigit TS4 is our top Thunderbolt 4 dock. It offers 18 ports, 98W power delivery, triple 4K display support, 2.5GbE Ethernet, and a UHS-II SD card reader. Build quality and thermal management are excellent. For most users, the Anker 777 offers 90% of the functionality at a lower price—dual 4K, 85W PD, and 13 ports. Choose CalDigit for maximum connectivity; Anker for best value.
Do I need Thunderbolt for dual monitors?
Not necessarily. Many USB-C docks support dual 4K displays via DisplayPort Alt Mode and MST (Multi-Stream Transport). The Anker 565 and J5Create dock both offer dual HDMI/DisplayPort at 4K 60Hz over USB-C. Thunderbolt provides more bandwidth and flexibility (e.g., triple 4K, 5K), but for dual 1080p or dual 4K, a good USB-C dock is sufficient. Check your laptop's USB-C specs for display support.
Why does my dock get hot?
Docks generate heat from power conversion and data transfer. Some warmth is normal. Premium docks like the CalDigit TS4 have better thermal design and stay cooler. If your dock is too hot to touch or causes disconnections, it may be overloaded—try fewer high-power devices or displays. Ensure adequate ventilation and avoid stacking other items on top. Most quality docks are designed to run warm but safe.
Can I daisy-chain multiple docks?
Thunderbolt supports daisy-chaining—you can connect a dock to your laptop, then another Thunderbolt device to the dock. USB-C generally does not support daisy-chaining docks. For multiple docks, connect each to a separate port on your laptop, or use a Thunderbolt hub like the CalDigit Element Hub to expand to multiple Thunderbolt ports, then connect docks to those.
