Can I use it as a 510 5V passthrough power source? Sounds like the perfect amount of voltage and power based on what I've read about USB passthroughs. I have a Totally Wicked branded inline 3.7V battery passthrough that I could use as a connector (sans battery) unless I have reason to be concerned about damaging it / melting wires or whatnot...or could cut my teeth with RCA connectors...
