Please Make Sure You Know Little much about current and voltages. I strongly recommend to make this under some supervision. \r
\r
220 AC (as input)\r
5v DC (as output)\r
\r
I used 4 chargers because i needed 2A max current output, you can use 3 or 2. depends on you.\r
\r
Use any kind of charger but make sure it is not more then or less then 5v. My chargers were 0.500amp each. so i got 2a from 4 of them.\r
\r
Hope you will like this project.\r
Thanks
