Is it OK to charge iPhone with iPad charger? Some people connect the iPhone directly through the lightning cable. At this time, the iPhone screen also shows a charging prompt. This seems to prove that the iPad charger can give iPhone charging. However, the output current of the iPad charger is 2.1A, while the iPhone is only 1A, will this cause damage to the iPhone?

 

In fact, the current on the charger is only the maximum current that the charger can provide. However, this does not mean that the charger will charge at the maximum current when charging the appliance.

 

The current output of the charger mainly depends on the mobile phone charger itself. Now there are special charging circuits in the regular mobile phone charger. They can be limited according to the situation, so no matter how much charger you use, you won’t have any problems.

 

Is it OK to charge iPhone with iPad charger?

 

This means that when you charge the iPhone with a 2.1A iPad charger, the iPad charger will not charge with a current of 2.1A, so don’t worry. In addition, if you use the iPhone charger to charge the iPad, there is no problem. At this time, the iPhone charger will charge the iPad with the maximum output current, which is 1A current, but only compared to the 2.1A charging time. It’s longer.

 

In addition, Apple’s charger can also tell if your device is an iPad or an iPhone. The general USB interface will have four pins, 5V power, GND ground, D+ data cable positive signal and D-data cable negative signal. The Apple charger will test the voltage of the charging device through the D+ and D- pins in the USB interface. The voltage on D+ corresponding to iPhone or iPod is 2V, and D- is also 2V. The 5V/2.1A charger used in the iPad has a D+ voltage of 2.7V and a D-voltage of 2V. Therefore, the charger can determine which device is currently being used by testing the different voltages on the two pins, and can also adjust the current accordingly.

 

In addition, whether the iPad charger can charge the iPad has the corresponding answer on Apple’s official website. Apple’s official website said, “The iPad USB power adapter is a 10W charger. But you can still charge all iPhone and iPod devices through it. But you’d better use the original Apple charger.”
