The iVOOMi Nexus 400 4 Ports USB Aluminium Hub is a compact USB expansion device designed to help users connect multiple USB peripherals through a single USB port on a laptop, desktop, or tablet. With 4 USB ports, this hub allows you to connect devices such as keyboards, mice, flash drives, external hard drives, printers, and more simultaneously, helping to overcome the limitation of having only one or two USB ports on modern slim laptops or PCs. Its aluminium body gives it a sturdy feel and makes it more durable than basic plastic hubs, while its compact design ensures easy portability for students, professionals, and travelers. Most USB hubs of this class support USB 3.0 high-speed data transfer, enabling file transfers at up to 5 Gbps — up to ten times faster than older USB 2.0 speeds — though exact specifications for this model are dependent on the manufacturer’s configuration. This high speed is useful for quickly moving large files between external storage devices or syncing mobile devices. The plug-and-play nature means there is no need to install drivers; simply connect the hub to your device’s USB port and it becomes instantly usable — ideal for users who want hassle-free connectivity.
