Hello all. I am new here and did a little searching around before deciding to post this. I am attempting to create converter that will allow me to charge my cell phone (android) from my bike (12v power). I was hoping to be able to create my own instead of just hacking apart a cigarette lighter plug.
My first attempt was with using a 7805 regulator (bench testing with a 12v power supply). In my tests the phone would go into charge and then stop. I had my meter plugged in and was checking the amp pull and when it went into charge it was hitting 1.55A and then it would stop and my meter would go into OL (overload). Then would start up again for about half a second. I presume I am hitting a maximum with the regulator. Here is the circuit I was using for this:

Does anyone have any suggestions as to what I can do to either the circuit or which regulator I can use to get this working?
