Four-Port USB 3.0 Hub

The j5create JUH340 adds four SuperSpeed USB 3.0 ports to a computer through a single integrated cable. It works with both Windows and Mac systems and is backward compatible with USB 2.0 and 1.1 devices. One port supports fast charging for phones, tablets and iPad up to 2.1A. The hub suits users who need more ports for peripherals without installing an internal card.

Passive Cooling And Low Power Draw

The compact aluminum housing dissipates heat passively with no fan, so the hub runs silently during normal use. It operates as a USB bus-powered device for standard peripherals or can switch to DC self-powered mode for demanding accessories. The recyclable, non-toxic enclosure keeps the unit cool to the touch under typical office workloads.

Sustained Multi-Device Throughput

Under continuous load across all four ports the hub maintains USB 3.0 speeds up to 5 Gbps per port, limited by the single upstream link to the host. Bus-powered operation may throttle high-draw devices if the host port cannot supply enough current, while the optional DC adapter removes that constraint. The aluminum body prevents thermal throttling during extended file transfers or charging sessions.

Questions about this item

How do I connect the JUH340 to my computer and which port should I use for the fastest charging?

Plug the integrated USB 3.0 cable into any USB 3.0 port on the computer; the hub adds four SuperSpeed ports and one of them supplies up to 2.1 A for fast charging phones or tablets.

What power options exist and when would I need the external adapter?

The hub runs from the USB bus for low-power devices; attach the optional DC power supply when you connect power-hungry peripherals that exceed the bus limit.

What throughput ceiling will I hit first during long, heavy file transfers?

The USB 3.0 interface caps sustained transfer at 5 Gbps, so that link speed is the first bottleneck you will encounter.
