USB hub helos HUB 4in1 USB-A 3.0 s 3x USB-A 2.0 portami

The helos HUB 4in1 USB-A 3.0 is a compact USB hub that converts a single USB-A 3.0 port into three additional USB-A 2.0 ports. The device is intended to provide extra legacy USB-A connectivity for laptops and desktop computers, enabling connection of keyboards, mice, flash drives and other low-power peripherals. It uses plug-and-play operation with no additional drivers required and features a lightweight, portable housing for easy transport.

Advantages

This USB hub expands one USB-A 3.0 connection into three USB-A 2.0 ports while maintaining backward compatibility with older devices. Its small footprint and low weight make it easy to carry with a laptop or keep on a desk without occupying much space. The hub supports straightforward plug-and-play use, so peripherals are recognized immediately on most operating systems. The product offers a practical and economical way to increase the number of available USB-A sockets when working with multiple peripherals.

Suitable for

• Connecting keyboards and mice to laptops or desktops
• Attaching USB flash drives and external storage for occasional file transfer
• Adding legacy USB-A peripherals where built-in ports are limited
• Mobile use with notebooks, ultrabooks and small form-factor PCs

Key specifications

• Input interface: USB-A 3.0 (host connection)
• Output interfaces: 3 × USB-A 2.0 ports
• Data transfer: USB 2.0 data rates on output ports (up to 480 Mbps)
• Power: bus-powered from host USB port (no separate power supply)
• Form factor: compact, lightweight hub housing
• Compatibility: works with operating systems supporting standard USB HID/Mass Storage devices

How to use

Plug the hub's USB-A 3.0 connector into an available USB-A 3.0 host port on your computer. Connect keyboards, mice, flash drives or other USB-A peripherals to the three output ports. The host system should detect connected devices automatically and install any required standard drivers. If multiple high-power devices are connected, verify that the host port can supply sufficient current or use devices with separate power sources.

Recommendations

Use the hub mainly for low- to moderate-power peripherals such as input devices and flash drives. Avoid connecting several high-current devices (for example, multiple external hard drives) simultaneously without external power, as the hub is bus-powered and current per port is limited by the host USB port. Keep the hub in a well-ventilated area and avoid placing heavy objects on top to prevent connector stress.
