Working principle:Charger All mobile phone chargers are actually composed of a stable power supply (mainly a stabilized power supply, providing stable working voltage and sufficient current) plus necessary constant current,Charger voltage limiting, time limiting, overshoot and other control circuits.
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,Charger output 4.4V can be used for 4.5V equipment, and 5.9V can be used for 6V equipment.
