The j5create JUH340 is a high-performance 4‑port USB 3.0 hub in a black aluminium housing that enables connection of up to four USB devices with SuperSpeed data transfer up to 5 Gbps. It is backward compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps) devices, and uses a USB 3.2 Gen 1 (Micro‑B) host interface with four USB 3.2 Gen 1 Type‑A ports. The hub supports high‑bandwidth peripherals such as external drives, high‑resolution webcams, video surveillance cameras, digital video cameras and multi‑channel audio devices, and also provides fast charging for smartphones, tablets and iPad® devices. The unit is powered from AC and features a durable black aluminium enclosure.

Advantages

The aluminium casing offers durability and helps dissipate heat during continuous operation. Four USB 3.0 Type‑A ports deliver SuperSpeed transfers up to 5 Gbps while maintaining full backward compatibility with USB 2.0 and 1.1. AC power support ensures stable operation with bus‑powered or high‑power peripherals, and the hub also supports fast charging for mobile devices.

Suitable for

• Connecting external hard drives and SSDs for fast data transfer
