From that link:
At the end of the day we are all tired. You turn off the lights and go to bed. You realize you have to charge your phone, and you have two choices: you either fight for a minute or two trying to plug in the phone in the dark, or you get up and turn the lights on to do it. Annoying, isn't it?
This cable is the solution: it has a built-in light that powers up with the click of a button.
Anyone else see the flaw in this logic?
