အေျခခံ Battery Phone charger ေလးပါ ညဏ္ရွိသလိုအသံုးျပဳႏိူင္ပါတယ္...

IC 1 = 7805=5v, 7812=4.5v ,7808 =8v (Power transistor or IC)

R1 = 5 Ohm, 2 Watt,(Resistor)Current limitter အတြက္ပါ
C1, C2 = 10uF/ 25V,(condenser)
D1 = 1N4007, 1N4001(အမွားခံအတြက္)
Battery, any 12 volt 

ေအာက္ကေတာ့ Circuit Diagram ပံုေလးပါ.
