Thanks for the quick reply! There are several possible issues with IOIO and fast charging (fuse, trace widths and contact resistance etc.) but as you said, the main thing is to signal to the device that it can pull more current. Maybe it's a question to other users - has anyone used the IOIO with Galaxy Tab while charging it?
