The Kindle Fire HD 7” is quite an intriguing device. Technically it uses its own operating system, “FireOS,” which is essentially a skinned variant of Android 4.2.2. Of course, it was only a matter of time before fully fledged Android was ported to this device. Actually, lots of development related activity has happened since September 2012, when the device was made public.
One of the latest development projects for this tablet comes from XDA Senior Member SafinWasi, who compiled a new kernel for this device with fast charge enabled. Fast charge itself isn’t a new concept, and you can find it in various projects since 2011. This modification enables charging with the full power of your AC or USB charger, enabling devices to be fully charged much faster than using the throttled current.
Installation of this kernel is pretty straightforward. All you need to do is reboot your Kindle into the fastboot mode, flash the kernel, and reboot the device. The magic can be done within terminal or by using one of the popular applications able to control the kernel.
If you own a Kindle Fire HD 7”, you may try to boost up the speed of its charging. To do so, head over to the FastCharge kernel for the Kindle Fire HD 7 thread and give it a try. Keep in mind that this kernel is described as an alpha, so there might be some flaws available here and there.
