I have a few systems on my bicycle that I would like to integrate into my battery, like: My headlight, the ability to charge my phone, and the ability to charge other USB items on the bicycle.... Has anyone used a step down transformer to turn something like 48v-52v down to 5v and used it to charge their phone on the go? Or power their headlamp?

I have bicycle wheel lights that also use batteries, but i think the voltage is 3.6v, is there such a thing as a single converter with several outputs, or would I simply have to get multiple converters?

A link to any guides would be helpful, or if you've already done it then a link to the actual converter would be awesome!
 
I searched for the word "walwart".

Some of the switching ones can work off of DC.
