The manual states that the USB amperage is a setting in EScribe. What I'd like to know, is if we can go over that 1A rating. Granted, 1A is a fair amount of juice, however, I have many devices (like my VC4 battery charger that draws 2.1A) and my anker batteries/5-port wall charger capable of pushing upwards of 2.4A. These packs are looking at 10A for the limit of charging. Obviously that's not going to happen here, but what exactly -can- we charge at?
