How to use

Connect the hub to a device with a USB‑C port and allow the operating system to detect connected peripherals and memory cards. Insert SD or TF (microSD) cards into the corresponding slots to access files via the system file manager or media applications. Attach USB devices to the USB-A ports as needed; most standard peripherals will operate immediately without additional software. Remove cards and disconnect the hub using the operating system’s safe-eject or unmount procedure where applicable to avoid data loss.

Usage recommendations

For reliable data transfers, avoid removing SD/TF cards or disconnecting the hub while files are being read or written. Use the hub on a stable surface and keep the USB‑C connector and card slots free of dust and debris. When connecting high-power devices, verify that the host device can supply sufficient power to external peripherals; if not, use externally powered options for those devices.
