Working of super fast Vooc charger

Jab Maine phli baar SuperVOOC charger haath me lia , the first thing came in my mind ki ye sala kaam kaise karta hai ! 🤔 I mean is qadar fast koi kaise charge krta hai bina heat hue !! Tb maine thodi si technicalities dekhi or tab smjh me aaya ki Super VOOC Ek Ampere based charger hai. ( Mostly hamre paas jo hote hai wo Voltage based hote h ) Mere paas jo charger hai wo 5V - 4A (20watt) pr operate krta hai. Ab ek mastt baat btata hu jo bhi phone SuperVOOC support karta hai uski battery cells split hoti hai ( padha hai kahi , link nh h lekin ) I mean 4000 mah battery ki cells ko 2000+2000 cells me split kar do or dono ko parallel mode pr jod do ! Ab voltage dono ko same chahiye but current jyada chahiye uske liye unhone Voltage ko 5V rakhke current ko sidha double kr dia . Isse fayda ye hota hai ki aap 2000 mah ki 2 battery ko ek sath charge krte hai. Time reduce ho jata h , yani jitne der me ek voltage based charger 2000mah charge krta h , ampere based charger 4000mah kr deta hai. Agar aap isko Qualcomm ke 18W charger se bhi compare krenge to bhi ye fast hoga. Ab baat karte hai heat kyu nh hota , simply H= I²RT , ab current jyada hai pr resistance or time dono km hai , ( R=V/I ) bs isiliye ye km heat karta.
