I see in charger adapter its shows 5v 2amp, isnít the USB capable same amp? Please advice. Thanks
The charging current (which you can check with Galaxy Chargin Current / Galaxy Chargin Current Lite) is around 450 mA over PC-USB (or unknown chargers without problems or good chargers + unknown cables) and up to 1800 mA with original charger over the original cable. If you divide 3100 by 1400 (which is average on original set since the charging algorithm tries to minimize heating) you get slightly over 2 hours, but when you divide 3100 by 450 you get over 6 hours on "classic" USB.
That being said I always favor the slowest charge (and I charge at 450mA over night) - the cooler the battery stays the more cycles it will survive.
