I bought this cord as a Replacement to an outlet charger or just to use a a USB charger for my 4th Generation iPod. My kids also have 4th Generation I pods and we all love the length and durability of this charger/sync cord. It works well in a different brand outlet charger as well as with a USP port on a lap top or PC. I've had problems with other USB charger/sync cords for iPod/iPhone that when plugged in would not play sound ( also purchased through Amazon) but this cord is long and when plugged into device sound still plays. Highly recommended...for length and performance.
