    Does anyone know if normal nokia 3210 chargers have a shut-off system
    on them or whether the phone does the control of charging? Seems normal
    to me that the phone would disconnect the supply when charging is
    complete - im trying to run a 3210 from a 12v source but maintaining
    its normal battery as a backup in case of power cut.
