Needed a US Extension Cable so I could extend my Iphone charger. (The outlet is on the floor) Now I can plug one end of this cable into the charger/outlet and leave it there, then loop the cable behind and onto my desk and plug in my charger! Now my charger could reach my phone/desk. Works perfect to extend any USB Charger! Only gripe is the price. Wish it was a tad cheaper, hence the 4 stars.
