is it possibble to charge the ipod/other mp3 players, by simply putting external 5v dc with a current limiting resistor in series.....of the player's usb port and leaving the data pins unconnected??
i asking because...charging the battery via pc's usb port may not be possible on occasions....so a standanole charger turns quite useful!!!

yes its possible but u have to use such an adopter that u r not using any resistance in series and it is supplying only required amount of current.
but if u cant find such an adopter, u have to select such a resistance that is not blocking all the current or max current. bcz mp3players have too low resistance for inputs so an AC2DC adopter with 200mA or something same would b used
