IPhone chargers and IPAD chargers are universal.
iPad and iPhone chargers are designed differently for a reason. The iPhone's battery capacity is small, requiring only 1A charging current to complete the charge in a reasonable time. Although the larger charging current can greatly shorten the charging time, it will bring more heat, and high temperature is the number one killer of lithium battery life reduction, so the maximum output current of the iPhone charger is designed to be 1A.
The charger of iPad is marked with 5V 2.1A, which means that the maximum output current of the charger of iPad can only be 2.1A. When using the iPad charger to charge the iPhone, although the iPad charger can provide A maximum of 2.1A current, but because the iPhone can only accept 1A current, the iPad charger only needs to accommodate it.
The iPad's battery is designed to charge at a current of 2.1A for the best charging time. If you use the iPhone charger to charge the iPad, because the iPhone charger can only provide a maximum current output, the entire charging time will be 2.1 times. Since Apple has a mark on the USB port data pin, the iPad knows that this is an iPhone charger, so it will not \"require\" more than 1A charging current, and will not overload the iPhone charger and cause damage.
As for the excessive current may lead to the breakdown of critical capacitors, it is completely illogical. The most basic function of the capacitor is \"through AC, separate DC\". The output of the charger is direct current, and no matter how much DC current, it can not pass through the capacitor, and can not cause the capacitor \"breakdown\". It is the high DC voltage that can break down the capacitor, that is, the \"breakdown voltage\".
Therefore, regarding the issue of using the iPad charger to charge the iPhone, the conclusion is that it is perfectly feasible, and neither the iPhone nor the charger will be damaged. The iPhone charger can also charge the iPad, but it will take a little longer to charge.
The charger is not universal, in this case you can only replace the corresponding charger, because the charger voltage is not the same, you have to replace the corresponding charger to stable use replacement solution
It can be universal, because the rated voltage used is 12 volts, universal voltage, so the voltage is the same, can be charged normally, and can be charged normally when it is used in normal life
The answer to whether the iphone and ipad data cable can be used is as follows:
1. The product data line of the same period is universal.
2, Apple's early iphone and ipad data cable is Apple 30P plug, he can not only support charging data transmission, and very friendly support for multimedia playback. However, because there are more pins, there will be a lot of inconvenience in the operation and use process.
3, now can only look at the model of the Apple phone and the model of the Apple tablet to get whether the data cable is common, because if it is the iphone4 series of Apple mobile phone data cable is not common with the ipad, because the physical interface can not be plugged in.
4, using the iPhone charger to charge the iPad is completely feasible, it will not damage the iPad and the charger.
5, iPad uses a 10W power charger, rated voltage is 5V, the maximum output current is 2A; iPhone charger specifications are 5V, 1A. In theory, both chargers have the same rated voltage and can be universal.
