You can effectively speed up charging under Misc and USB, not using a wall charger.
Oh, regarding the damn update procedure of xxTweaker: I will revive my trusty Gingerbread OTA updater and seperare the tweaker from the kernel. The app is simply too mighty now...
Charge current is physically limited to 450 mA and 650 mA steps. Actually I'm not sure if 650 mA are chosen depending on a rounded value (i.E. ((650 - 450) / 2) +1 or already if the value is above 450 mA (450 + 1).
