Powering a USB hub? 5v options?
Okay let's see here. I guess I'm trying to clean up my USB cables. If I get a 4-port hub for my center console I can run 1 cable to it and have my Lilliput and Powermate on it with no problems and still have extra ports for a card reader, OBD-II reader, whatever. Sounds good to me.
This is the one I like. Now, how do I power it?
I suppose I could run a 12awg wire off the 5v line of the Opus, but that would draw even more of it's very limited power. I'm pushing it's limits as it is. And it would also be annoying to run another wire (isn't this what I'm trying to avoid?).
I could tap into the cigarette adapter's 12v line with a 12v->5v adapter. Think it could handle 2 amps for the hub (500mA x4) ? I could also use the 12v from my headunit's wiring harness. Where do I get one of those adapters anyway? I couldn't find it at radioshack. It has to be a regulated 5v right?
