Specifications

Notes

Does not support audio or video transfer. USB-C port is for hub power input only — not for device charging. Please allow ±1mm tolerance due to manual measurement.

Q1: Will using multiple devices affect transfer speed?
A: It may. When multiple devices transfer data simultaneously, USB bandwidth is shared, so actual transfer speeds may vary depending on the connected devices and workload.

Q2: Why is my device sometimes not recognized?
A: Try reconnecting the hub and the device and make sure the connection is secure. Connecting multiple high-power devices may also affect available USB power.

Q3: Will the rotating joint become loose over time?
A: The rotating mechanism is designed for normal angle adjustment. Avoid using excessive force when adjusting the angle to reduce long-term mechanical stress on the joint.

Q4: Why does one USB device work while another does not?
A: Different USB devices have different power and compatibility requirements. Some high-power devices may require more power, and performance may vary depending on the connected device.

Q5: What should I do if a connected device suddenly disconnects?
A: Check that the USB connection is secure and try disconnecting some high-power devices. If the issue continues, try another USB port on your computer.

Q6: Is it normal for the hub to become warm?
A: Some heat during extended data transfer or when multiple devices are connected is normal. If the hub becomes unusually hot, stop using it and check the connected devices.
