USB cable Renkforce 1421511 — USB Type A (male) to Micro-USB Type B (3.0), 30 cm

Renkforce 1421511 is a 30 cm USB 3.0 cable with a standard USB Type A (male) connector on one end and a Micro-USB Type B (3.0) connector on the other. It is intended for short-range connections between computers, external storage devices and mobile devices that use the Micro-USB Type B 3.0 interface. The compact length reduces cable clutter and is convenient for use with laptops, docking stations and portable drives where a full-length cable is unnecessary.

Advantages

The cable supports USB 3.0 data transfer rates when both host and device are USB 3.0 compatible, allowing faster file transfers compared with USB 2.0 micro variants. Its Micro-USB Type B (3.0) connector provides the wider plug profile required for many external hard drives and certain mobile devices. At 30 cm length the cable offers a tidy connection with minimal slack, which is useful for portable setups and close-proximity device arrangements. The cable is fitted with standard USB Type A (male) for broad compatibility with computers and chargers.

Suitable for

• Connecting external hard drives and enclosures with Micro-USB Type B (3.0) ports to computers
• Short data-transfer connections between laptops and compatible mobile devices
• Charging and syncing devices that accept Micro-USB Type B when used with appropriate power sources
• Portable workstations or travel setups where a short cable reduces tangling

Key specifications

• Connector A: USB Type A (male)
• Connector B: Micro-USB Type B (3.0) (male)
• Length: 30 cm
• Standard: USB 3.0 compatible (backward compatible with USB 2.0)
• Primary functions: data transfer and device charging

How to use

Insert the USB Type A (male) connector into a compatible USB port on a computer, laptop or USB power adapter. Insert the Micro-USB Type B (3.0) connector into the device’s Micro-USB Type B port. For best data transfer speeds ensure both host and device support USB 3.0; if either side is USB 2.0 the connection will negotiate to the lower speed. Handle connectors by their housings and avoid bending the cable sharply at the ends to maintain connection reliability.

Recommendations

Use the cable for short, direct connections; avoid routing it through high-traffic areas or pinch points. When connecting external drives, connect power to the drive (if required) before data transfer. Store the cable coiled loosely to prevent strain on the connectors and prolong service life.
