Using this cable is a breeze. First, connect the USB - A end to a power source or a device with a USB - A port. Then, plug the Type - C end into your mobile phone or controller board. You can start charging your device or transferring data right away. When using, make sure the power source is stable to avoid any potential damage to your device. For maintenance, keep the cable away from sharp objects to prevent cuts. Also, don't bend the cable too sharply or pull it forcefully as it may break the internal wires. If you're not using the cable, store it in a cool and dry place.
