USB 2.0 7-Port Hub Exsys EX-1177-2 with Metal Housing and 5V 4A External Power Supply

Exsys EX-1177-2 is a 7-port USB 2.0 hub in a metal housing that expands a single USB connection into seven downstream USB 2.0 ports. The device comes with an external 5V 4A power supply to ensure stable operation when multiple peripherals are connected. Its compact metal enclosure is intended for desktop or workstation environments where additional powered USB ports are required for peripherals such as keyboards, mice, flash drives and external storage devices.

Advantages

The metal housing provides improved durability and heat dissipation compared with typical plastic hubs, while the external 5V 4A supply allows simultaneous use of several power-drawing devices without relying solely on the host port. USB 2.0 compatibility ensures broad device support and plug-and-play operation with common operating systems. The seven downstream ports offer flexible connection options for multiple peripherals and accessories.

Suitable for

• Expanding USB connectivity on desktop PCs and workstations
• Connecting keyboards, mice, printers and scanners
• Attaching flash drives, card readers and external hard drives
• Small office setups that require several powered USB ports
• Temporary workstation setups, kiosks and shared desks

Key specifications

• Interface: USB 2.0 host connection and seven USB 2.0 downstream ports
• Power: external 5 V, 4 A power supply included
• Housing: metal enclosure for enhanced durability and heat dissipation
• Compatibility: supports standard USB 2.0 transfer rates and USB 1.1 devices
• Mounting: compact desktop form factor suitable for placement on a work surface

How to use

Connect the hub to a host computer using the provided upstream USB cable, then plug the external 5V 4A power supply into a mains outlet and the hub’s power input. After power is applied, attach downstream USB devices to the available ports. The hub is designed for plug-and-play operation; most operating systems will recognize connected devices automatically. For devices that require high current, ensure they are connected one at a time and confirm the hub’s power connection is secure.

Usage recommendations

For reliable operation, use the included 5V 4A power supply when connecting multiple or high-current devices. Avoid placing heavy objects on the metal housing and ensure adequate ventilation around the hub to maintain stable temperatures. If a connected device is not recognized, disconnect and reconnect that device or restart the host computer. Use USB 2.0 cables of good quality and keep cable lengths reasonable to maintain signal integrity.
