CalDigit TS4 vs Anker 777 – Which Thunderbolt Dock Should You Buy?

The CalDigit TS4 has 18 ports vs 13 on the Anker, including triple 4K display support (vs dual), 2.5GbE (vs 1GbE), and a UHS-II SD card reader. The TS4 also delivers 98W vs 85W. The Anker is more compact and costs about $100 less. For most users, the Anker covers dual monitors, Ethernet, and USB adequately. The CalDigit is for power users who need triple displays, faster Ethernet, or more ports.

If you need triple 4K displays, 2.5GbE, or more USB ports, yes. The TS4 also has superior thermal design and build quality. If you're fine with dual 4K and 1GbE, the Anker 777 is the better value. The extra $100 buys you headroom and future-proofing—if you might add a third monitor or upgrade your network, the TS4 pays off. For a fixed dual-monitor setup, save the money.

Yes. Both are Thunderbolt 4 docks with broad compatibility. They work with MacBook Pro, MacBook Air, and Windows laptops with Thunderbolt 4 (or Thunderbolt 3). Driver support is usually plug-and-play on Mac; Windows may need Thunderbolt drivers from your laptop manufacturer. We've tested both with Mac and Windows laptops with no issues.

The CalDigit TS4 has a slight edge—heavier, more premium feel, and a reputation for long-term reliability. The Anker 777 is well-built but lighter and more plastic. Both are stable and durable. For a permanent desk setup, the TS4 feels more substantial. For a dock you might move between home and office, the Anker's lighter weight is a plus.
