Vision 4USB30CM-BLACK USB 2.0 Splitter 1 Male to 4 Female 30cm Black

USB 2.0 four-port splitter

This Vision splitter converts a single USB-A port into four female ports so users can attach multiple peripherals such as keyboards, mice, flash drives or game controllers to a laptop, desktop or console. The 30 cm cable keeps the hub close to the host device while adding the extra connections needed for a crowded workstation or gaming setup. It draws power directly from the host port and requires no driver installation.

USB 2.0 bandwidth and power limits

The hub operates at the USB 2.0 specification, capping combined data throughput at 480 Mbps across all four ports, so high-bandwidth devices such as external SSDs will share that single channel. Total downstream current is limited to 1 Amp, meaning power-hungry peripherals like portable hard drives may not spin up reliably without a separate powered hub. The adapter is also incompatible with automotive USB or Apple CarPlay systems.

Four ports for low-power accessories

Comfortable uses include connecting a mouse, keyboard, printer, scanner, card reader or VR headset where each device draws modest current and does not saturate the 480 Mbps link. The shared 1 Amp budget and single USB 2.0 transaction translator become bottlenecks when several high-throughput or high-draw devices are active simultaneously, so the splitter is not suited for multiple bus-powered hard drives or high-speed capture cards.
