Prototype of Kleptocharger for Android device

Power bank is a device used to support charging up a device battery, especially a mobile phone's battery. Since design of common power bank contain of battery cell and power controller, it will have some empty space to create a modified power bank. We could implement a tiny Micro controller named teensy. Teensy will create power bank detected as a storage media and all the selected data will be copied into media card in the power bank. Beside of teensy implement, we could also implement SD card shield for storing all the captured data. This concept is a proof concept that modified power bank could be implemented. The results of this research prove that a modified power bank only works one mode at a time.
