Me and my university friend just managed to make two quantities of devices, both for the same purpose to provide 12 volt, 1 ampere to dc pin out which are attached to my internet modem and tp-link router also. its working good as according And it requires following stuff mentioned below:
-- Voltage Regulator KIA 7812 ( Fixed output voltage 12V,1A)
-- 6.0A bridge rectifier KBJ608G ( low reverse leakage current )
-- Ac transformer ( output 12volt, 1A)
-- cut off circuit ( locally made in the market )
-- 6 volts lead-acid battery (4.5A)
I could get a 12 volt single battery but that was not available in the house, instead i used two 6 volts batteries, so we mostly collected stuff that was available and to get easily from any nearest electronics shop without taking an extra effort to make it more accurate project. because i am not related into this field much so i am here to discuss it more extensively and more practically in terms of electrical engineering.five Pictures of the first device are attached here,named as a1,a2,a3,a4,a5 and the second device's pictures are also attached here with names as z6,z7,z8. well the first device that we built is similar to other One . but only difference is that we attached two capacitors in the circuit board.In second device i am not really into understanding that Is there any need to wire 35v 33uf electrolytic capacitor
between positive and negative terminal of cut off circuit ? and also there is attached a yellowish film capacitor 104K in the circuit board. You can see these attached pictures here.
