An ONTEN 10-port USB 3.1 hub is a device that expands one USB port into ten, offering fast 5Gbps (USB 3.1 Gen 1) or 10Gbps (Gen 2) data transfer for peripherals, often featuring an aluminum body for heat dissipation, individual switches and LEDs per port, and external power for multiple drives, making it great for expanding ports on laptops/desktops with stable power for hard drives and fast file transfers, with modern versions supporting USB-C connections.
