Compact USB-C hub for laptop expansion

The Rocstorage Y10A200-A1 adds four ports through a single USB-C connection on a MacBook, PC laptop or Chromebook. Its aluminium charcoal-grey enclosure is small and light enough to stay in a laptop bag or briefcase. The hub draws power directly from the host device so no separate adapter is required. It suits users who need quick access to both USB-C and USB-A peripherals while travelling.

Build integration and port layout

One upstream USB-C port links the hub to a Thunderbolt 3 or USB-C host, instantly providing three USB-A ports and one extra USB-C port. All four ports share a 5 Gbps bandwidth pool, so total throughput is divided among connected devices. The slim form factor leaves adjacent ports on the laptop free and does not block neighbouring connectors. Bus power means the unit adds no cable clutter beyond its short integrated lead.

Included accessories and software impact

No separate cables, drivers or configuration utilities are supplied in the package. The hub operates on the standard USB 3.0 class drivers already present in macOS, Windows and Chrome OS, so it works immediately after plugging in. The absence of an external power brick keeps the kit minimal but limits the hub to low-power peripherals such as mice, keyboards, printers or portable hard drives. High-draw devices will need their own power source.
