USB 3.0 Y‑Cable for 2.5" Portable Hard Drives

This is a USB 3.0 Y‑shaped cable, recognizable by its blue jacket, which is the typical color‑coding for USB 3.0 cables.

Interfaces

• 1 × USB 3.0 Micro‑B male connector (connects to your portable hard drive / HDD enclosure)
• 2 × Standard USB‑A male connectors (blue plastic inserts for USB 3.0)
  • Main USB‑A: handles both data transfer and basic power supply
  • Auxiliary USB‑A: extra power‑only branch for supplementary current

Function

Many older computer USB ports cannot supply enough current for 2.5‑inch external hard disks.

• Plug the main USB‑A port for data communication.
• When the hard drive fails to be detected, disconnects randomly or has unstable read‑write performance, plug in the second auxiliary USB‑A connector to get extra power.

Specifications

• Protocol: USB 3.0, theoretical transfer speed up to 5 Gbps, backward compatible with USB 2.0
• Cable material: PVC outer sheath, oxygen‑free copper conductors with shielding for anti‑interference
• Application: 2.5‑inch portable hard drives, external HDD enclosures, disk docks

Usage Notes

1. Connect the Micro‑B end to your external hard drive.
2. Normally only the main USB‑A needs to be plugged in if your USB port delivers sufficient power.
3. Use rear motherboard USB ports on desktops for better power output; front‑panel ports often have insufficient power.
4. Not for mobile phone charging. It cannot connect two computers to each other.
