Hub USB VALUE USB 3.0 Desktop 7 portas com fonte de alimentação

The VALUE USB 3.0 Desktop Hub 7 Ports with Power Supply is a compact USB hub designed for desktop environments. It provides seven downstream USB Type-A ports that support USB 3.2 Gen 1 (also referred to as USB 3.1 Gen 1) data transfer speeds up to 5 Gbit/s and comes with an external power supply delivering 5 V at 4 A. The hub has a plastic housing and measures approximately 85 mm × 59 mm × 15 mm, and includes a host cable with a USB 3.2 Gen 1 Micro-B connector for connection to a computer or other host device.

Advantages

The VALUE hub combines multiple ports with a dedicated power supply to support several devices simultaneously without relying solely on host power. Its USB 3.2 Gen 1 support enables high-speed data transfer for external drives and peripherals. The compact footprint and lightweight plastic construction make it suitable for placement on a crowded desk while the included cable and power adapter allow immediate use after setup.

Suitable for

• Connecting multiple USB peripherals such as keyboards, mice, printers and scanners
• Attaching external storage devices for high-speed data transfer
• Expanding USB ports on laptops and small form-factor PCs with limited built-in ports
• Charging and powering multiple low- to moderate-power USB devices that are compatible with a 5 V, 4 A supply

How to use

Place the hub on a stable surface and connect the external power supply to the hub and to a mains outlet. Use the supplied USB cable to connect the hub's Micro-B host connector to a compatible USB port on your computer. After connecting power and the host cable, the hub is ready to accept downstream devices. Plug USB Type-A devices into the hub's ports; the system will enumerate connected devices automatically according to the host operating system's USB handling. For optimal transfer speeds, connect high-speed devices to the hub while the external power supply is connected.

Recommendations

For reliable operation, avoid connecting high-current devices that exceed the combined available current of 5 V/4 A. Use the hub on a flat, ventilated surface and connect high-bandwidth devices (such as external SSDs) while ensuring the power adapter is connected to maintain stable transfer rates. Regularly update the host system's USB drivers to ensure full compatibility with USB 3.2 Gen 1 speeds.
