Baseus BS-OH080 UltraJoy Series 4-Port USB HUB

The Baseus UltraJoy Series 4-Port USB HUB (BS-OH080) is a compact and practical USB hub that expands a single USB-A port on your laptop or PC into four USB 3.0 ports — ideal if your device has limited USB slots and you need to connect multiple peripherals simultaneously. Designed for convenience and portability, the hub is small and lightweight, making it easy to carry around for work, school, travel, or everyday desktop use. Despite its compact size, it delivers solid performance: the USB 3.0 ports support data transfer speeds up to 5 Gbps, allowing fast file transfers — for example moving a 1 GB file in just a few seconds. The hub’s internal circuitry uses independent chips per port to ensure stable signal and power delivery even when multiple devices (like a mouse, keyboard, external HDD/SSD, flash drive, or other accessories) are connected. Safety mechanisms such as short-circuit protection, over-voltage protection, and over-current protection increase reliability and protect connected devices from electrical hazards. Thanks to its “plug-and-play” nature and wide compatibility across major operating systems (Windows, macOS/AppleOS, Linux, etc.), no extra drivers are needed — making setup instant and hassle-free. Overall, the UltraJoy 4-Port HUB is a simple yet powerful accessory to significantly expand connectivity and make peripheral management much easier for everyday computing tasks.
