When I had a Nexus S, there was an option to enablele which said USB Fast charge. What it did is, it made it possible to charge your device fast like you're charging it via a power cord, only thing was, it would have been connected to a computer via USB. You couldn't transfer files or anything, but it would charge much faster. For those that don't have a charger, it's great, because your device is charged fast, like it was connected to the regular charger.
Thanks for your help, I will try to ask in the kernel threads.
