USB hub UGREEN CM219 4-port USB-A 3.0 with 1 m USB-A 3.0 cable - black

UGREEN CM219 is a compact 4‑port USB hub that expands a single USB‑A 3.0 host port into four USB‑A 3.0 downstream ports. The hub integrates a 1 m USB‑A 3.0 cable and supports plug‑and‑play connection for data transfer between a computer and multiple peripherals. Its black finish and lightweight construction make it suitable for desktop setups and mobile use where extra USB‑A ports are needed for external drives, input devices and printers.

Advantages

The UGREEN CM219 provides four USB‑A 3.0 ports delivering high‑speed data transfer rates compatible with USB 3.0 devices while remaining backwards compatible with USB 2.0 and 1.1. The built‑in 1 m USB‑A 3.0 cable avoids additional adapters and helps keep the setup tidy. The compact housing offers portability, simple plug‑and‑play operation requires no drivers, and the hub’s black finish integrates unobtrusively into most workstation layouts.

Suitable for

• Connecting external hard drives and SSDs for file transfer and backups
• Attaching keyboards, mice and other input devices to a single USB‑A port
• Connecting printers, scanners and other office peripherals
• Expanding ports on laptops or desktops with limited USB‑A connectors

Key specifications

• Number of downstream ports: 4 × USB‑A 3.0
• Host connection: integrated 1 m USB‑A 3.0 cable
• Compatibility: USB 3.0 speeds with backward compatibility to USB 2.0/1.1
• Data transfer: supports high‑speed USB 3.0 rates (theoretical maximum per device depends on host and peripheral)
• Color and finish: black, compact enclosure
• Power: bus‑powered from the host USB‑A port (no external power supply included)

How to use

Connect the integrated USB‑A 3.0 cable from the UGREEN CM219 hub to an available USB‑A 3.0 or compatible USB‑A port on your computer. Plug USB‑A peripherals into any of the four downstream ports. The hub operates in plug‑and‑play mode; the operating system should automatically recognize connected devices. For power‑hungry devices such as some external drives, use a host port with sufficient power output or connect devices one at a time if the host cannot supply enough current to all ports simultaneously.

Usage recommendations

For optimal performance, connect high‑speed storage devices to the hub when the host supports USB 3.0. Avoid using multiple high‑power devices simultaneously if the host port has limited power output; consider a powered USB hub or a direct connection for devices that require sustained high current.
