Using this cable is easy. First, connect the USB - A end to a power source like your computer's USB port or a wall charger. Then, plug the USB - C end into your device, such as a Samsung Galaxy phone or a digital camera. You'll see the LED readout showing the charging current. When it comes to using it for data transfer, just connect your device to the computer and you're good to go. As for maintenance, keep the cable away from sharp objects to avoid cuts. If it gets dirty, you can gently wipe it with a dry cloth. Remember, since no software is included, some operating systems may need drivers to recognize your device. Make sure to check if your system requires them before using the cable.
