When you go to plug in an eGo battery with the usb adapter included that sets a limit of what the battery can draw fromthe 3.3v pc or 5v ac adapter provides.
The part I put a line through, I understand. I figure in one part you are talking about the 5VDC output from the AC-USB adapter.
What do you mean by '3.3v pc'? The changing output from the internal charge circuit?
