Many children’s mobile phones just find a charger when they run out of power. It doesn’t matter what model it is or whether it is suitable for use. As long as it can be connected to the data cable, it doesn’t matter if it is charged first. You are so casual, have you ever considered the feelings of your mobile phone?
Will the iPad charger charge the iPhone faster?
The nominal "2.4A" on the bottom of the iPad charger refers to the maximum current of 2.4A, and our mobile phones also have power conversion circuits inside, which will limit the charging current. So the maximum charging rate is ultimately determined by the mobile phone.
After testing, the maximum charging current of the iPhone is about 1.3A, so it is only 30% faster at most. It's just that the original charger cannot draw the maximum current of the iPhone, but the iPad charger can.
In other words, the iPad charger cannot fully utilize the maximum charging rate of 2.4A on the iPhone.
Summary
1. Using an iPad charger to charge your iPhone does make the charging rate slightly faster (by about 30%).
2. Using an iPad charger to charge your iPhone will not have any adverse effects on it.
3. iPad can achieve the fastest charging rate only when used with an iPad charger.
