ASO technology, completely Made in Italy, patented by Witty Srls, was developed by a team of electronic, mechanical and management engineers following a two-year study in the laboratories of the University of Rome "La Sapienza".
The ASO is able to read the energy that the smartphone requires from the charger and disconnect the battery from the mains when the device’s energy requirement has been met. It's like unplugging the charger from the electrical outlet. Unlike all charge controllers, ASO does not read the voltage or capacity of the battery, but analyses the current flow between the device being charged and the charger.
Disconnecting the battery when fully charged prevents it from remaining at its end-of-charge voltage even after reaching 100%, a situation that is extremely damaging to the lithium cell electrodes, thus allowing the battery to lower to a more comfortable voltage and begin its discharge cycle.
It's like relaxing your muscles after an intense workout.
