CalDigit TS4 (Thunderbolt 4 / 18 Ports / 98W Host Charging / Dual 4K@60Hz / Mac/Windows/Chrome / ~$300) Review
The CalDigit TS4 is a Thunderbolt 4 dock with 18 total ports, 98W host charging, dual 4K@60Hz or single 8K@30Hz display support, and Mac/Windows/Chrome compatibility for ~$300.
Independently named the best USB-C docking station in 2026 for most WFH setups and the definitive Thunderbolt 4 dock for serious professionals — the only Thunderbolt 4 dock that delivers 98W charging, dual 4K-60Hz output, and 18 ports without thermal throttling under sustained load. 98W of host charging is specifically sufficient for both 14-inch and 16-inch MacBook Pro models under sustained load, a genuinely demanding real-world benchmark this dock meets reliably. Flawless Mac/Windows/Chrome compatibility with no driver installation required makes this the gold standard for universal compatibility across different office environments and personal device choices. Packs all 18 ports into a compact vertical dock design, a genuine space-efficiency advantage over sprawling horizontal docks with comparable port counts. Specifically recommended as the safest pick for unknown requirements, since its broad port selection and universal compatibility cover the overwhelming majority of real-world use cases without needing to guess at specialized needs in advance.

Comparison to Alternatives
Versus the CalDigit TS5 Plus — that steps up to Thunderbolt 5 with more ports and higher charging wattage for a real price premium, worth it specifically for buyers with Thunderbolt 5-equipped laptops. Versus the Razer USB4 Dock — that matches Thunderbolt 4 dock performance at a lower price for buyers without a Thunderbolt-certified laptop port.

Expert rating9 / 10
Best USB-C dock for most WFH setups — 98W charging, dual 4K@60Hz, 18 ports, and flawless Mac/Windows/Chrome compatibility.
Best for
- Most WFH and professional setups wanting the safest, most broadly compatible pick without overthinking requirements.
- MacBook Pro M3/M4 users specifically, since most current MacBook Pro models still use Thunderbolt 4 rather than Thunderbolt 5.
Not for
- Buyers with Thunderbolt 5-equipped laptops wanting to use the full available bandwidth — the TS5 Plus is the right choice for that.
