Dual USB 3.0 Y-cable for portable drives
This BUCIER Y-cable connects a USB 3.0 Micro-B device to two USB Type-A ports using a 40 cm lead. The extra Type-A plug draws supplementary power from a second port so a portable hard drive can spin up reliably without an external adapter. Shielded twisted-pair construction supports SuperSpeed transfer up to 4.8 Gbps when both host and device are USB 3.0 compliant. Molded strain relief protects the junctions for long-term durability.
Suits owners of USB 3.0 portable hard drives
Buyers with a drive that requires more current than a single USB 2.0 or 3.0 port can supply will benefit from the dual-head design. The cable is not for devices that use USB-C, Lightning or standard Micro-USB 2.0 connectors. It also does not add power delivery negotiation or voltage step-up beyond what the two host ports already provide.
Check your drive connector
Verify the portable drive has a USB 3.0 Micro-B socket — the smaller rectangular port with a distinct step — because this cable will not fit USB-C, Lightning or older Micro-B 2.0 ports. Ensure the computer or hub offers two free Type-A sockets close enough for the 40 cm split to reach both. Confirm the host ports are USB 2.0 or 3.0; the cable works with either but achieves 4.8 Gbps only on USB 3.0.

Questions about this item
Does the 40 cm Y-cable need two free USB Type-A ports on my laptop to power a portable hard drive?
Yes, the cable has two USB Type-A plugs and draws power from both ports (2.0 or 3.0) to run the drive.
Will the Micro-B connector work with my older USB 2.0 external drive?
No, the device end is a USB 3.0 Micro-B plug, which is physically different from the Micro-B connector on USB 2.0 drives.
How can I confirm the link is running at the full 4.8 Gbps after I plug it in?
Check the host controller speed in Device Manager or System Information; it should report SuperSpeed (USB 3.0) for the connected drive.
