Chargers for iPhone and iPad, are they all the same?

The day is running out and our mobile's battery is in reserves. We are going to arrange to load it but ... we remember that we had lost the charger, we had left it in a friend's house, we had problems and burned, etc.

With so much cable, adapter and charger loose in the drawer, although there are excellent ways to organize them , we do not know what combination is ideal to charge our mobile.

Are all the chargers the same? What advantages, disadvantages and dangers are there when we use the charger of another device with our smartphone? Today, we are about to open the trunk of the shippers to review all the differences, advantages and disadvantages of the different models available.

USB and charger
Let's see a little theoretical lesson to put ourselves in situation. Except for some compact chargers, we will need two components when charging our iPhone: a USB cable and the charger itself . The USB cables consist of 4 small threads that have the following function:

Thread 1: Voltage of 5V
Thread 2: Data -
Thread 3: Data +
Thread 4: Mass
That is, through wires 1 and 4 passes the electrical current and through pins 2 and 3 the data, thanks to which we can synchronize our iPhone with the computer.

IPhone chargers are responsible for providing a constant voltage to our mobile, which absorbs the current you need to complete the charge . The chargers that the manufacturers supply work converting the alternating current of our electrical network -230V- to direct current with smaller voltages, for example 5V. Once seen this comes the big question.

Is any charger useful?

Having reached this point and having the basic knowledge of the operation of the cables and chargers, we will see that as long as the plug corresponds the answer could be yes, but we could have fatal consequences. For them we are going to see the three points that the loader must fulfill in order for it to work properly:

Output voltage
We look at the section that says "Output" in our charger and check that the voltage is 5V, the standard for iPhone and iPad . If it were 5.3V, nothing would happen since it is within an acceptable range. The problem is that it is a difference of 0.5V because it can destroy our battery.

Load speed

This characteristic is indicated to us just after the output voltage. This data tells us the speed at which our device will load. For example, a 1000 mAh -1A-out charger will charge twice as fast as a 500 mAh one . Could this burn the mobile? The answer is no. This data is the maximum load speed, if the mobile needs less, it will give less and will be more relieved. The problem in this section comes when we connect a device that requires 1A to a charger that only gives us 500 mAh, since this will require more to the charger overheating and, of course, charging slower.

Smart charger
We already have the two previous sections in order, but we need the last and not least. Some manufacturers, Apple among them, have designed the USB charging ports of their devices so that if they do not receive signal through the data ports, they also disable the load ports . In this way they make sure that it can only be loaded from the USB port of a PC or from its official chargers.

These last ones bring a chip that, through the data wires of the USB connector, enable the charging mode . Without this component, we jump on the screen the well-known message "the accessory is not compatible with this device" At Apple this system is recognized as an MFi certificate. Does it mean you have to buy an original one? no, there are compatible cables and chargers that are MFi certified and work perfectly.

If you have read and understood all the steps, you will understand better the operation of the chargers and you will have a better choice when choosing a substitute to the current charger. What chargers do you usually use for your iPhone and your iPad? Have you ever had problems with your device's battery for using third-party chargers?
