Product Info

The chassis is made from post-consumer recycled (PCR) aluminum, and the packaging is FSC-certified. It ships with a Thunderbolt 4 cable (approx. 0.8m), power adapter, and quick-start guide.

Best Use Cases

Video editors and creative pros: Users running M4 Pro/Max MacBook Pros who need multiple 4K monitors for timeline editing, color grading, and preview. Thunderbolt native mode minimizes latency. Data analysts and traders: Multi-monitor setups for data visualization, plus 2.5GbE for fast network transfers and SD card slots for quick data ingestion. MacBook users with desk setups: Those who keep their laptop in clamshell mode and want a single-cable solution with 100W charging and off-host device power. Windows DisplayLink users: Laptops without Thunderbolt can still drive multiple displays via USB-C DisplayLink, though performance may not match Thunderbolt-native connections.
