Compact silver aluminum four-port USB 3.0 hub with short attached cable and external power adapter

LORDWORLD

LORDWORLD 4-Port USB 3.0 Hub 15W Adapter (JUH340)

SKU CH-EK4M-CCZ98

Adds four USB 3.0 ports with 5 Gbps transfer speed, 2.1 A charging and a 15 W power adapter

  • Adds four USB 3.0 ports from a single connection
  • 5 Gbps transfer rate, ten times faster than USB 2.0
  • Fast-charges phones and tablets at up to 2.1 A
  • Compact aluminium housing, non-toxic and recyclable
  • Works bus-powered or with the included 15 W adapter

Four USB 3.0 ports from one plug

This hub adds four USB 3.0 ports to a Mac, MacBook, Windows laptop, Surface, XPS or PC using a single upstream connection. It delivers SuperSpeed transfer at 5 Gbps and remains backwards compatible with USB 2.0 and 1.0 devices. The 15 W power adapter enables fast charging for phones, tablets and iPad up to 2.1 A.

Aluminium housing and 2 ft cable

The compact aluminium enclosure is non-toxic and recyclable, keeping the hub cool during sustained transfers. A 2 ft extended cable gives flexible placement on a desk or in a travel bag without straining the host port. The hub supports both bus-powered and DC self-powered peripherals so external drives and accessories stay operational.

Replaces single-port dongles

Users who currently rely on a single-port adapter gain four simultaneous connections for storage, input devices and charging. The upgrade is worthwhile when multiple USB 3.0 devices must run at full bandwidth or when fast charging is required alongside data transfer. Builders needing more than four ports or a different host interface will need a larger hub.

Questions about this item

What is the maximum data rate of the USB 3.0 ports on the JUH340 hub?

The four ports run at USB 3.0 Super Speed, giving a 5 Gbps transfer rate that is ten times faster than USB 2.0, while remaining backward compatible with USB 2.0 and 1.0 devices.

Does the JUH340 hub require an external power adapter to operate?

A 15 W power adapter is included and lets the hub run in self-powered mode for demanding devices; it can also function in bus-powered mode when the adapter is not connected.

How is the JUH340 hub installed and what is the common mistake to avoid?

Connect the supplied 2 ft cable to a host USB port, plug the 15 W adapter into mains power for self-powered operation, then attach peripherals; the frequent error is skipping the adapter when charging tablets or multiple high-draw devices, which then fall back to limited bus power.
