Is there a way or an app to control maximum charge current?
I have an older powerbank. Connecting my Xperia10II to the 2A output port starts charging for a few seconds, with message popup on screen. About three seconds later the indicator on powerbank goes off and the charging stops. I think the internal overcurrent protection trips and turns off the output until replugging. So I think there is an incompatibility with signaling the capabilities.
Other Android phone charges without problem on same cable.
