This Glowing Charging Cable Varies in Light Speed According to Battery

You'll never lose your phone in the dark again with this glowing charging cable. The LED-lit USB to Micro USB cable from AllPuter charges or syncs your smart phone with sparkling convenience. It also lets you visualize how charged your phone is: the cable's lighting runs like a current that flows faster when fully charged and slow flow means still charging.

The concept here is to visualize electricity. Essentially, you can see electricity flowing into your device with a tangible current flow of how much energy is actually flowing into your device. The LED strip along the cable and its lighting varies in speed to match the battery level of your phone. The smart cable shuts off power when the phone is fully charged.
