New phones have 9V chargers while the battery for all I know of is a single 3.7V lipo.
First of all, how is it possible to charge a single cell with such high voltage and second thing is, if it is converted back to 4.2V or something and some phones advertise crazy 50W and even over 100W charge speed, then that means that the current is supposed to be huge.
How do they do that?
