The LEDs on the cable move from the wall adapter towards your phone as if to make it look like the lights are actually the power moving through the cord. But the coolest feature about the LED cable is that as your phone charges and fills up its battery, the animation of the LEDs begin to slow down. This allows you to simply look at the speed of the LED lights on the cable instead of having to turn on your phone to see how full your phone's battery is.
The LED lights on the charging cable are blue in color, but you can find other colors available on Amazon here. The cable has a standard USB connection on the opposite side of the phone charging side which can be used to charge your device on a laptop, in your car, or using any standard wall charging adapter.
