that is not really helping the only info there is that it charges faster on AC than on direct USB, but no word on if it is usable during AC-Charge -.- I just though someone could confirm it with say a 200Ohms phone charger or something, that it does NOT actually turn into UMS mode as the D2/D2+...

does anyone know if it is possible to charge the C2 while using, which would be essential to in car usage, the D2(+)s AC port seems gone
