If I recall correctly, at a show last November, the Maestro battery compartment had two cables. One microUSB to charge the battery pack (automatically from the Maestro when plugged in), and one standard USB to power the Maestro from the battery pack. Now there is only one cable in my Maestro battery compartment. So it looks like I need a separate charger and will need to remove the battery every few hours for charging. Is that right? Am I remembering correctly?
