    I have a problem Im looking for some help on. I have a old VW bus that is still 6 volt... I want to be able to charge my phone with it but dont want to fry it by connecting it directly to the system. I tried making a 7805 circuit with a couple 10uF capacitors (radio shack) but that only produced 4.7v or so which didnt power the phone.

    Can anyone recommend a way to do this?
