Actually i think it wont charge faster on PC USB port as that only delivers 500ma. However if u use a USB wall charger in some cases it is detected as Pc USB port and thus enable slow charging mode despite the charger could deliver more power. In this case enabling fast charge helps u charge faster as it will be forced to AC mode. But sideeffect is that fast charge will disable USB data transfer.Thanks. Without any negative Character? Means charging in car and pc USB ports? It does not affect the charging with original Samsung Chargingdevice?
