USB cable DeLOCK 81221 USB 2.0 0.5 m USB A USB C Blue

The DeLOCK 81221 USB cable is a compact 0.5 m connection cable with a USB A plug on one end and a USB C plug on the other. Designed for USB 2.0 compatibility, it supports a maximum data transfer rate of 0.48 Gbit/s and features gold-plated contacts for stable signal transmission. The cable’s blue jacket provides easy visual identification and simple integration into desktop, laptop or accessory setups.

Advantages

The cable combines the widespread USB A interface with a USB C connector to enable direct connections between older host devices and newer peripherals. Gold-plated contacts reduce the risk of signal degradation and improve contact reliability over repeated insertions. Its 0.5 m length minimises cable clutter while providing sufficient reach for close-proximity connections. Constructed for USB 2.0 speeds, it is suitable for reliable data transfer and basic charging tasks.

Suitable for

• Connecting USB A hosts (PCs, laptops, chargers) to USB C peripherals (external drives, smartphones, dongles)
• Short-distance data transfer between devices supporting USB 2.0
• Cable routing on desks where a short, identifiable lead is required
• Temporary or portable setups such as travel or presentations

How to use

Insert the USB A connector into a compatible host device (for example a computer or a USB power adapter) and plug the USB C connector into the peripheral device. Ensure both ports are clean and free of debris before connection. For data transfer, allow the host operating system to recognise the connected device and follow on-screen prompts to access files. For charging, verify the connected power source provides the required current for the device.

Recommendations

Use this USB 2.0 cable for short-distance connections where USB 2.0 bandwidth is sufficient. Avoid excessive bending near the connector ends and do not expose the cable to prolonged mechanical stress. If higher transfer speeds or power delivery are required, consider a cable specified for USB 3.x or USB Power Delivery standards.
