Can iPad charger charge cell phone?

It is entirely possible to use an iPad charger to charge an iPhone, and the iPhone or charger will not be damaged. The iPhone charger can also charge the iPad, but it takes longer to charge.

The main reasons why iPad chargers can charge cell phones are:

There is a reason why iPad and iPhone chargers are designed differently. The iPhone battery capacity is low and requires only 1A of charging current to complete charging in a reasonable time. Although larger charging current can greatly reduce the charging time, it will generate greater heat, and high temperature is the main cause of shortening the life of lithium battery. So the maximum output current of the iPhone charger is designed to be 1A. The iPad charger is marked 5V 2.1A, which means the iPad charger can only output amaximum current of 2.1A. When using an iPad charger to charge an iPhone, although the iPad charger can provide a maximum current of 2.1A, since the iPhone can only accept 1A of current, the iPad charger must accept it. It's like driving on a 4 lane highway. When you encounter a toll booth, only one toll booth is open, so there is only one car passing through the toll booth at the same time.

The iPad battery is designed so that the charging time is optimal when the charging current is 2.1A. If you use an iPhone charger to charge an iPad, since the iPhone charger can only provide a maximum output current of 1A, the total charging time will be about 2.1 times longer than before. Thanks to Apple's little tricks on the data pins of the USB interface, the iPad knows that it is the iPhone charger, so it will not "require" a charging current greater than 1A, et will not overcharge the iPhone charger or cause damage. It's also like being on a highway. Although there are four toll booths in the toll plaza, due to construction work there is only one lane actually open to traffic, so there is still only A maximum of one car passes through the toll booth. at the same time.

General solutions for iPad cannot be turned on:

1 When iPad freezes, cannot be turned on and does not there is no response, you can try turning the device on and off. Simultaneously press and hold the Home button on the home screen for more than 10 seconds. See if you can force a restart.

2. If the force restart is successful, you will see an Apple logo on the screen. After the reboot is successful, you can use it normally.

3. Of course, sometimes this can be because the battery is dead.rearranged, which causes it to automatically stop. No matter how you use it, it cannot be turned on. When this happens, please log in. First connect the iPad to the AC charger.

4. If it turns off automatically due to low battery, a battery icon will appear on the screen.

5. Additionally, the iPad battery must be charged more than 5% before it can be turned on normally. If the battery is extremely low, let it charge first, then turn it on.

6. If the above methods are ineffective, it may be a hardware failure of the Apple phone. It is recommended to send it to an Apple authorized service store for testing.
