you won't get 2 amps without a transformer, at most you can get 200mA with a X1 capacitor that is as big as a transformer ...
what size do you have for your power supply ?
take a look at this one : **broken link removed**
7.0 cm x 3.8 cm x 3.1 cm
if i used a two charger output connected in parallel
then voltage same current increase it is possible or not.......
and if i connects 5v 2amp to microcontroller what happen then what happens ......damage or not....
