I'm using yoobao 11200 obviously OEM one.. Buying for my frenS too c'ze of attractive the simply way to charging when you outing... Can charge 5 time for IP4 but cannot charge for IP4S... Just rarely yoobao can charge IP4S using IP4S original cabel... Other thing, you must have soft hand c'ze their plug is soo easy broke.. It just pop-inside n to claim waranty like take forever to claim...
