The circuit above is a simple circuit to charge phone battery . Charge battery uses an output transformer secondary voltage fast-flowing with 9 Volt 350 mA. First voltage 220/110/120/240 VAC 50/60 Hz , will be reduced to 9 volts,then rectified by 4 diodes 1N4007 and then flowed to light Led voltage power resistor 1 kOhms inhibited. + directly to the battery volltage and voltage - across 47 Ohm resistor and Led charge indicator which is inhibited resistor 100 Ohm then directly to the phone battery.
