I needed dual voltage power supply for my lab that runs on mains
-electricity (wall power) and slowly charges attached 12V Lead-Acid
-battery. Lead-acid battery in turn provides high current when needed
-as well as power in portable situations or when mains electricity is
-not available.

-!!!WARNING!!! I use USB-A connectors for power output, but IT IS NOT
-COMPATIBLE WITH USB DEVICES AND POSSIBLY WITH EXISTING USB CABLES.

-Normal USB devices and cables should not be plugged in! It would
-damage device/cable and likely power supply.

As seen, it has dual voltage output. Additionally one wire is
-dedicated to data transmission and can be used with <a href="https://en.wikipedia.org/wiki/1-Wire">1-wire</a>
-protocol. Power supply simply passively links all data wires together
-but does not participate in communication.

+1-Wire data router/hub is really simple. Power supply simply passively
