It won't make any difference. The power of the charger is large, the charging time of the mobile phone battery is short, the current is small, and the charging time of the mobile phone is longer. The large-screen smart phone (6-inch screen) on the market now has a charger that is 4 amps, and the mobile phone battery is also 4 amps (4200 mah).
Because the mobile phone battery itself has a charging and overdischarge protection circuit (because the special physical properties of lithium batteries are determined, the protection circuit is inseparable. Overcharge and overdischarge are not safe for lithium batteries. So there must be a protective circuit)), so use any charger to charge the phone, there is no harm.
When it fully charges the phone battery, it will automatically turn off the charging circuit. When the battery power is reduced to a certain degree, it will automatically turn off the power supply circuit. That's the special thing about cell phone batteries.

The current domestic smart phone fast charging function uses private agreements, that is, each fast charging technology is different, and naturally there is no way to achieve universal. For example, OPPO's VOOC flash charge, Huawei's SuperCharge, vivo's super fast flash charge and so on. The fast charging technology used by these manufacturers is not the same, there are 40W, 44W, 65W, if the mixed charger is unable to achieve the fast charging effect
There are range, battery type, voltage and current power, suitable battery capacity, limited universal, not universal.
The fast charging device of the mobile phone, distinguish the block fast charging protocol, compatible with the fast charging protocol, fast charging is universal. High current requires charging cable charging port support.
The mobile phone fast charger can also output a common 5V2A power supply, which can be universal.
