The Manhattan IUSB3-HUB3SDM connects to a single USB-A port and expands it into three SuperSpeed USB 3.2 Gen 1 ports plus a dual-slot memory card reader. Data transfer reaches up to 5 Gbps on USB 3.0 devices, while backward compatibility with USB 2.0 and 1.1 ensures older peripherals also work without adapters.

The hub draws its power directly from the host USB port — no separate power supply is required. An LED power indicator confirms the hub is active. The integrated SuperSpeed USB-A cable is 13.5 cm long, keeping the hub positioned conveniently close to the laptop or desktop without tangling.
