A USB charging cable is designed primarily for delivering power to devices, while a data cable can transfer both power and data. Most modern cables support both functions, although some older or specialized cables may only facilitate data transfer. For example, some USB-B cables may only support data transfer without offering power delivery.

To test the quality of your USB cable, you can perform several checks:

• Data Transfer Speed: Connect your devices and transfer a large file to see how quickly it transfers. Compare this speed to the expected rates for your cable type (e.g., USB 2.0 vs. USB 3.0).
• Charging Speed: Use a device with known charging times to see if your cable charges it within that timeframe.
• Physical Inspection: Check for any visible damage, fraying, or loose connectors.
• Compatibility: Ensure the cable works with multiple devices without issues; a good quality cable should function seamlessly across various platforms.
