I've had some success with using an Anker Astro3E USB battery with a few phones using USB Audio Recorder Pro. Using a USB HDD split power cable to connect my Dacport LX to the battery and to my Galaxy Nexus, the battery provides full power to my Dacport LX which is exactly what I wanted! I tried this with my Galaxy S III and to my surprise the battery actually charged the S III while providing power to the Dacport LX as well. Cool! I wonder if that's a hardware or kernel feature..?
CM10.1 ROM on both phones. I sure hope that USB Audio Recorder Pro service app comes out sometime soon. The basic playlist feature isn't fond of my music folder structure.
Anyways, over at my college people have been eyeing me down, some with a look of panic on their face I'd say. It's only a matter of time before someone yells "BOMB!!!" - but hell, maybe they have. Not like I'd hear them anyway
Using that JKase USB OTG cable at the moment, waiting for a different brand one to arrive... I'd stay away from the JKase if you guys are buying OTG cables, this thing started to bend (and randomly cut out, crashing the phone while playing music) in the micro USB jack area immediately after I got it, and it likes to fall out of the jack too.
