USB kábel DELOCK 81521 — USB 2.0, Micro-USB B na USB A, 5 m, čierny

DELOCK 81521 is a 5 m USB 2.0 data cable with a Micro‑USB B male connector on one end and a USB A female connector on the other. It supports USB 2.0 transfer speeds up to 480 Mbit/s and features gold‑plated contacts for reliable connectivity and improved corrosion resistance. The reversible EASY USB design on both connectors makes plugging simpler by eliminating the need to align top and bottom sides.

Advantages

The cable provides a long 5 m reach for connecting Micro‑USB devices such as smartphones, tablets, cameras or external drives to computers or chargers. Gold‑plated contacts help maintain a stable connection and resist corrosion. The EASY USB reversible connectors reduce fumbling when connecting devices and are twist‑proof to allow insertion from either side.

Suitable for

• Connecting smartphones and tablets with a Micro‑USB port to a computer or USB power source
• Connecting external hard drives or memory sticks with USB A to Micro‑USB devices
• Data transfer at USB 2.0 speeds (up to 480 Mbit/s) and charging at standard USB current

When it may not be suitable

This cable supports the USB 2.0 standard only; it does not provide USB 3.x transfer speeds or the higher power delivery capabilities of newer USB standards. It is not intended for devices that require specific proprietary charging protocols or faster data rates beyond 480 Mbit/s.

Key specifications

• Cable length: 5 m
• Connector 1: Micro‑USB B (male)
• Connector 2: USB A (female)
• USB version: USB 2.0 (up to 480 Mbit/s)
• Contact plating: gold‑plated contacts
• Colour: black

How to use

Connect the Micro‑USB B male plug to the Micro‑USB port of your device and plug the USB A female end to a USB A male cable or adapter that goes to a computer or power adapter. The EASY USB reversible connectors allow the plug to be inserted without checking top or bottom. Ensure both ends are fully seated for reliable data transfer or charging.

What to consider before purchase

• Requires Micro‑USB on the device and USB A on the host or adapter
• USB 2.0 speed limit (up to 480 Mbit/s) — not suitable for USB 3.x throughput needs
• Length of 5 m may affect charging speed on some power sources due to voltage drop

Recommendations

For reliable performance, connect directly to a powered USB port or a quality charger and avoid sharp bends or heavy strain on the cable near the connectors. If you need higher transfer speeds or USB Power Delivery, consider a cable or adapter that supports newer USB standards.
