Apple's mobile phone charging interfaces are not all the same.
1, Apple iPhone4s and before used a 30-pin large interface, which is a three-in-one data cable. Need to distinguish between positive and negative, the charging head is wide, and the charging port on the mobile phone is also large. The 30 pins can support iPhone 4S/4/3GS/ 1, iPad 3/2/ 1, iPod touch 4/3/2/ 1, iPod nano 6/5/4/3/2/ 1 and iPod classic.
2.iPhone5 and later models adopt 8-pin (Lightning interface) lightning interface, which supports forward and backward insertion and is compact and beautiful. Apple High-speed Multifunctional I/O Interface 201September 212nd. Apple has released a brand-new Lightning Dock interface, which can be translated into "Lightning" interface in Chinese.
(1) The line length is about105cm; Double-sided USB design, plugged into the USB interface of the computer, can be used on both sides, and an adapter IC is added to match the double-sided USB design.
(2) In addition to the most intuitive advantages of both parties, it can also increase the metal contact area of the USB intermediate layer. Not only can it be compatible with the existing 12W adapter of iPad, but it is also expected to realize the patented technology of 20V extremely fast charging that Apple has not yet released.
Extended data
1, three-in-one data line:
(1), also known as multifunctional data line, adds a combination scheme on the basis of the original data line, and is equipped with a combination PCB, which can support a variety of devices and avoid the trouble of frequently looking for data lines.
(2) Integrated with Lightning, 30-pin interface and MicroUSB port, it is compatible with various devices and can be connected to any smart phone or tablet computer, including iphone, ipad, Samsung, HTC and other products. For example, the Micro USB cable can support smartphones from Samsung, Blackberry, HTC and other manufacturers.
(3)30 pins can support iPhone 4S/4/3GS/ 1, iPad 3/2/ 1, iPod touch 4/3/2/ 1, iPod nano 6/5/4/3/2/ 1 and iPod classic. Applicable to all products such as IPHONE4, IPHONE5 and MICRO USB interface.
2. Lightning interface:
(1) 8-pin contacts on both sides can work normally no matter how inserted. So don't worry about inserting it backwards. Apple also officially claimed that the new interface is not only easier to use, but also more durable. At the same time, it is pointed out that the new Lightning interface is an "all-digital" interface with "adaptive function".
(2) "Adaptive" actually means that specific signals required by accessories can be transmitted through the interface according to different accessories. Like the previous 30Pin Dock interface, the new Lightning interface also supports video output. It is precisely because of this feature that Apple can launch the Lightning-to-HDMI/VGA converter.
(3) 3) The advantage of Lightning interface lies in its size. It is 80% smaller than the original 30-pin connector, which means that the space you need to reserve for the connector on the device will be at least 80% smaller. Not to mention the related circuit complexity is reduced from 30 pins to 8 pins.

How many aces is the charging head of Apple's mobile phone?
The charging plug current of Apple mobile phone is 1440 mA.
Specific content:
1.iphone5s output voltage 5V, current1a. The battery capacity of the iPhone5s is r 1440mAH. Theoretically, the iPhone 5S can be fully charged in about 2.5 hours, and the best time for the first charging of the iPhone 5S is to continue charging after being fully charged 10 minutes.
2. The input voltage of 2.iPhone 6S is 100-240V to 50-60Hz, and the output is 5V and1a..
3.iPhone 6 original charger with charging voltage of 5V and current of1a..
4.iphoen7 is 2900mAh, which is 150mAh higher than the previous generation. According to official data, its service time is longer than that of iPhone 6s Plus 1 hour. Unfortunately, for this battery close to 3000mAh, Apple still has no plans to equip it with fast charging function, and the official standard charger is still 5V-1A.
Why does the plug heat up when Apple's mobile phone is charging?
During the charging period, the electronic components in the charger are working at full load, and the heat dissipation of the shell is not good, so it is normal to generate heat. As long as it is not overheated, there is no problem. After charging, the temperature of the charger will naturally drop until it is close to room temperature. If you encounter this phenomenon, then everything is normal and you can use it with confidence.
When the mobile phone is charging, it is normal for the charger to generate heat, which is related to the current intensity output by the charger and the ambient temperature. The following is the solution to the overheating of the charger.
1. Don't put your mobile phone on clothes or quilts to charge it, which is not conducive to heat dissipation.
2. If the mobile phone charger is overheated, it is best to charge it in a cool environment in summer, such as an air-conditioned room. This way, the mobile phone charger will not overheat.
How to distinguish iPhone charging head
The official approval of charging iPhone4/4S with iPad charger.
Apple's official reply: The iPad charger is 10W, which is true and designed for iPad devices, but you can also use it to charge iPhone and iPod series models.
That's right. Apple said no problem. Charge. Without much explanation, many people still feel that it is not "transparent". Well, let's see why Apple agreed. Let's start with the chapter on junior high school physical and electrical. Remember P=UI?
Why can I?
Power is determined by voltage and current. Now we are talking about the adapter, so the rated voltage has been fixed at U=5V, which is decided by the adapter itself, and the constant voltage is 5V (let's just press an integer). Then what can determine P is the current I, which can be considered to be determined by the equipment. The impedance of your iPhone and iPad determines how much current you need to output.
Or go back to the parameters of the two adapters just now:
IPad charger: 5. 1V 2. 1A, rated power10.71w.
IPhone charger: 5V 1A, rated power 5W.
What is said here is that the iPad with 10W( 10.7 1) is used to charge the iPhone with a 5W charger, so how should it be understood?
We all know the knowledge of physics. Before we discuss it, we have to let you know the nominal parameters of the two adapters.
5V is the rated output voltage set by the two adapters at the factory, and this will not change (know you have something to say, don't be serious). As for whether the iPhone4/4S charger is 1A or the iPad charger is 2. 1A, these are the maximum currents allowed to pass, that is, the highest iPhone4/4S charger provides 5W output power and the iPad charger provides 10W output power.
In other words, whether you connect the iPhone or iPad or not, the adapter has a voltage output of 5V.
Can Apple's mobile phone be charged with other plugs?
It is best to use the original Apple charger. Otherwise, it will charge the phone.
Supplement:
Generally, the voltage of a mobile phone charger is 5V, which is the same as that of the original iPhone6 charger. Therefore, if you must choose other brands of chargers, it is best to use a current of around 1A, so that although the charging speed is slow, at least it will not burn out the mobile phone because of too much current.
When the iPad or iPhone is connected to the charger, the different voltages on these two pins can distinguish which charger is currently used, and adjust the load accordingly, thus charging safely. This design can also prevent ordinary chargers from charging Apple devices.
The charging current is not only determined by the maximum output current of the charger. The charging current of mobile phones and tablets is controlled by PMIC. After inserting the charger, the software should judge the voltage of D+ and D- and analyze the type of charger. If it is a 2. 1 charger of the IPAD, the IPAD will set the maximum charging current to 1.5A, and also check the voltage of the charger. If the charger is charged with a charging current of 1.5A, the voltage of the charger will not be reduced. The system is a closed-loop system.
In addition, if the iPhone6 is damaged due to charging in the process of using other brands, Apple will not be responsible for after-sales maintenance, so it is necessary to be cautious when using chargers of other brands. It's best to buy big-name products with quality assurance, and don't buy fake chargers of unknown origin.
What's the use of unplugging the iphone charger?
The charger is in a split state. After unplugging, you can insert the power extension cord here and then connect it to the AC power outlet.
The advantages of this method are: firstly, the length of the charging line is indirectly extended; Secondly, it provides other solutions for the power socket that is inconvenient to plug the charger directly.
Different countries use different plug specifications. Apple charger is made of the same part, and the plug is made of several different parts. Finally, I want to put them together. The charger is the most complicated part, so there is no need to redesign the charger and re-manufacture the production line. This can reduce the cost.
Extended data
This portable power adapter is easy to use and can easily charge the iPod at home, office and on the road.
This universal design means that as long as you have the Apple Travel Power Adapter Kit (which needs to be purchased separately), you can use it all over the world.
