    Im looking to make a converter that will have an input voltage of 12 v (have not tested for input amperage yet) and an output of 5v @ either 3 amps or 4.2 amps (current has still undetermined currently).

    I would like to make it from scratch but will settle for modifying a prefabricated curicut. With the prefabricated circut the only thing I can think of is using an old usb car charger but im unclear on how to increase the output amprage.

    If Its possible I will then build the curcits (~ 10 total units) and attach them into specific locations throughout my car.
