  1. That's not how it works. As voltage is constat (5v/9v/12v). If circuit is connected to 5v it will only draw current it needs. Smart chargers just figure out the voltage supply.

  2. idhr dikhta hai ke confidence se bolo to log sch maan lenge. kush bhi glt information faila rhe..

    charger me bs voltage dekhni hoti hai, usually 5, 9, 12V support krte hain phone chargers.

    Wattage ya Current agr zada hai bhi to farak nhi pdta. wo bs maximum capacity hoti hai jo force nhi kr skta charger.

    aur, aisa nhi hota ke 15W supply hota hai aur 5W me convert ho jata hai. Aisa hoga to charger pe fulke bn jayein itna garam ho jaye.
    jb device hi km wattage wali ho, to supply bhi utni hi wattage hoti hai. thodi wastage hogi, around 1-10% usually, mgr itna nhi ke 15W supply aur 10W waste ho jaye.

  3. The conclusion is correct, but the explanation is not exactly correct, there is no "conversion" happening.

    Power Wattage is the product of Voltage and Ampere. W= V x I
    For simplicity assume the charger is only capable of constant voltage supply. i.e 5 volt.

    Here only V is decided by the supply ( charger). The current I is drawn (decided) by the the mobile phone.

    Even if the charger supports 1000 Watts . ( That is 5V and 200 Amperes). You can safely connect this to any small device which has a rating of 5 V. Let's say the mobile is rated only 1 Watt. ( That is 5 V x 0.2 Amps). Still there won't be no issues. Because power is asked. Not given.

    When it comes to multi stage voltage chargers, there is a two way communication with the device to determine if any voltage other than 5V is supported. If the device replies with affirmation, then the other Voltage will be selected. But again current is not given, it's asked so is the Watt. You can supply the Wattage only as much the mobile requires.

    Also the thin wire part is misleading, if the charger and mobile both are capable of drawing higher wattage, but if the wire is not rated for that wattage, the wire will get hot and the insulation might catch fire, thin wire will not work as a resistor. It will work as a light filament temporarily.

  4. Ghanta ka smart Redmi ka charge serf redmi ka device ko fast charge Karsakta ha.Oppo and Realme ka charger serf OPPO and realme Kohi fast charge Kar sakta ha.
    But moto ka pd charger la lo laptop ko bhi fast charge kar sakta ha.
