A simple utility that reads/writes to force_fast_charge on devices that have kernel support for it. I wanted to make an easy to use application for this so I didn't have to manually change the file every time I wanted to use fast charge.
Fast charge allows for a faster charge when charging from a PC (USB 3.0 only) or a car.
To see if you can use this feature, use a root explorer and navigate to /sys/kernel/fast_charge. If there is a file named force_fast_charge in that directory then you can use this app! If you are unsure if your kernel has fast charge support, look up the features. I'm sure they are listed somewhere online.
