My external battery (AC or USB out) powers other devices (i.e., Anker bluetooth speaker) but with the same USB → 5v cable, it does not power up my new UR12.
This is related to my other (possibly hopeless) issue: getting a signal from my Audio Technics Pro 35 phantom mic → UR12 → lightning adapter → iPhone8 camera app for VIDEO. The 3rd party “ProCamera” app says it recognizes external mics, but it won’t recognize the signal from the UR12.
Anyway, first things first. Why doesn’t the battery pack power up my UR12? Is it that USB → 5v cable is not the answer? Does it instead have to be an actual DC (from the wall plug) to 5v ??
