The PAC cable lights up as electricity runs through it so you see the power moving, from the connector to your device.
When your smartphone or tablet has a low battery, electricity flows quickly through the cable. The more power your device accrues, the slower the electricity moves until the light eventually goes out. Reminding you that charging is complete. So you can pull out the cord. This preserves the health of the battery by not overcharging and prevents the device from continuing to draw power needlessly as well.
