It is possible to charge faster, but I prever not too, It produces more heat and can damage your device.
NX-Kernel by Neo allows you to do that.
I think this only works with the 230V/115V charger, computers can't charge faster than 500mA, US...
I'm following this thread for quite a while, thanks for making this more active.
I don't know how to port such a thing, my developer skills are zero.... I own a GT-N7000, I do know a lot about rooting, S-off, CWM and stuff. I've got basic skill...
