Bought this as a gift for our (18 year old) nephew to add length to his iPhone charging cord (his specific request).  When we couldn't find an actual iPhone cord in the length he wanted, I found this extender.  He was actually so happy to open it that he plugged it in right away.  When we saw him next, we were told by his mother that he had called her to his room that same night to show her the range he now had with his iPhone while charging it!  Think we won coolest aunt/uncle award for that night ;).
