How the charger works

All mobile phone chargers are actually composed of a stable power supply (mainly a regulated power supply, providing a stable working voltage and sufficient current) plus necessary control circuits such as constant current, voltage limit, time limit, and overshoot.

The output parameters marked on the original charger (refers to the line charger): such as output 4.4V/1A, output 5.9V/400mA, refer to the relevant parameters of the internal regulated power supply. For example, output 4.4V can be used for 4.5V equipment, and 5.9V can be used for 6V equipment.
