USB 3.0 to Micro B Y-Splitter HDD Power & Data Cable

USB 3.0 to Micro B Y-Splitter Cable with Dual Power Supply

Keep your external hard drive powered and running smoothly with this USB 3.0 Male to Micro B Male Y-Splitter Cable by OULLX. Designed specifically for high-capacity HDDs, this cable features a dual USB-A design — one connector for data transfer and one dedicated to extra power — ensuring your hard drive always gets the current it needs for stable, uninterrupted performance.

Why You Need This Cable

Standard USB 3.0 ports deliver only up to 500mA of current. If your external hard drive demands more than that, a single-port connection may cause disconnections or slow transfers. This Y-splitter solves the problem by drawing supplemental power from a second USB port, keeping your HDD running at full capacity without the need for an external power adapter.

Key Features

• Dual USB-A to Micro B Design: One USB-A plug handles data transfer while the second USB-A plug provides auxiliary power to support high-capacity HDDs.
• USB 3.0 Standard: Supports high-speed data transfer so you can move large files quickly and efficiently.
• High-Quality Insulation: Built with polyethylene (LDPE) and PVC internal insulation for strong anti-interference protection and reduced signal attenuation.
• Versatile Power Head: The extra USB power connector is compatible with other Micro USB interfaces, giving you added flexibility.
• 20cm Secondary Line: The auxiliary power cable measures a convenient 20cm, keeping your desk tidy without excess cable clutter.
• No Assembly Required: Ready to use straight out of the package — simply plug in and go.
• Plug & Play: No drivers or software installation needed. Compatible with Windows, Mac, and Linux systems.

Frequently Asked Questions

Q: What is a USB 3.0 Y-splitter cable and why do I need one for my HDD?

A: A USB 3.0 Y-splitter cable features two USB-A connectors on one end and a single Micro B connector on the other. One USB-A plug handles data transfer while the second provides extra power. This is essential for high-capacity external hard drives that require more than the 500mA a single USB 3.0 port can supply, ensuring stable connections and preventing data transfer interruptions.

Q: Is this cable compatible with my laptop or desktop computer?

A: Yes. This USB 3.0 Y-splitter cable is universally compatible with any computer or device that has standard USB-A 3.0 ports, including laptops and desktops running Windows, macOS, or Linux. It requires no additional drivers or software — simply plug in both USB-A connectors and connect the Micro B end to your HDD.

Q: Can the extra power USB connector be used with other devices?

A: Absolutely. The auxiliary USB power connector on this cable is compatible with other Micro USB interfaces beyond just hard drives. This gives you added flexibility to use it as a supplemental power source for a range of Micro USB-compatible devices.
