The 1x4 USB HUB HBO4 is a versatile and compact device designed to expand a single USB port into four additional ports. Whether you need to connect multiple USB storage devices, input devices like a mouse and keyboard, or printers and scanners, the HBO4 USB hub ensures that you have enough ports to get the job done. It is the perfect solution for users with limited USB ports on their laptop or desktop computer who need to manage multiple devices simultaneously. The USB 2.0/3.0 compatibility ensures that the 1x4 USB HUB HBO4 can provide adequate speeds for most everyday tasks. While USB 3.0 can provide faster transfer speeds (up to 5Gbps), the hub will also work with older USB 2.0 devices (which typically support speeds up to 480Mbps). The hub is also typically backward compatible with USB 1.1 devices, meaning you won't run into compatibility issues when connecting older USB gadgets.
