How critical is the output voltage of a mobile phone charger in determining the charging current?
For example, if we were to use a well-regulated power supply as a charger with a low output impedance and no current limiting, will it make a significant difference if the voltage is set at, say 4.8, 5.0 or 5.3, all other thing being equal? Or will the phone's internal circuit compensate for the differences as long as the voltage is above a certain minimum value?
