CalDigit TS4 18-Port Thunderbolt 4 Dock

Pros

  • +18 ports including 3x TB4, 3x USB-C, 5x USB-A, DisplayPort, 2.5GbE, SD + microSD, audio
  • +98W sustained upstream charging holds MacBook Pro 14 at full CPU/GPU load with margin
  • +Native dual 6K@60Hz over two downstream TB4 ports with zero DisplayLink drivers
  • +2.5GbE Ethernet measurably faster than gigabit for NAS transfers and wired video calls
  • +Brushed-aluminum chassis with documented 3+ year owner reliability

Cons

  • $379.99 is overkill for a basic two-monitor setup
  • No HDMI port — HDMI-only monitors need a DP-to-HDMI adapter
  • Front USB-C ports are 20W/7.5W data ports, not full-power TB4 charging
  • Larger desktop footprint than slim hubs
