Phone Battery Charger circuit

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.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


Hi is great that u hav come up with ths wonderful circuitry and simple way to make and repair phone battery chargers. I do appreciate your work, keep it up.

Ok , the abve crcuit is smple , but still hav qualty, hhe
thnx also for visit.,.
