smartphones offer a useful wireless charging feature. For some users, such a function is really necessary, while others consider it to be of little use. Very often, one question remains unanswered: how can energy be transmitted without a cable?

1.Fast charge and electromagnetic induction

To fully understand how wireless charging works, you need to get an idea of ​​the electromagnetic field, and more broadly, of electromagnetic induction, which you have already dealt with if your kitchen has an induction stove for cooking. 

And what can be the connection between the induction cooker and the smartphone, you ask. Electromagnetic induction is a system of energy transfer, and this means that such energy can be stored or used.

So how can energy be transferred? In this case, it is a question from the field of the use of force. Imagine two people holding opposite ends of the rope in their hands: if one person decides to shake the rope to make waves in the form of a wave, then the rope in the hands of the other person will also begin to oscillate in the form of a wave. 

This is a very generalized example of explaining electromagnetic induction: a force sends energy from one point to another. The base unit (powered by electricity) transfers energy to the smartphone using an electromagnetic field. The sensors on the smartphone convert the incoming energy and transmit it directly to the battery.


2. How is charging speed calculated?

Here again, the whole point is valid. Since energy is transmitted through an electromagnetic field, the speed depends on such a field. In other words, the larger this field, the faster the charging speed. The problem is that the electromagnetic field is small because the smartphone (in particular, the material from which it is made) imposes certain restrictions. Because of this, your smartphone has a limited power transfer rate, for which the manufacturer indicates the optimal voltage.

3. What is Qi?

Qi is the most popular wireless charging technology. This technology is not limited to a specific manufacturer - theoretically, all manufacturers can use it on their devices. Samsung and Apple are among the best-known brands using Qi technology.
In general, I must say that Qi seeks to standardize wireless charging technology, which implies several safety rules necessary to comply. These rules include such a moment as the power of the devices, which plays a role in the charging speed.
Thanks to Qi, wireless charging technology has made significant progress: charging speeds have increased, and electricity no longer causes noticeable heating of the device. Qi uses not only electromagnetic induction charging technology, but also magnetic resonance technology.

4. Is my device compatible with the charging?

You probably made the decision to abandon wired charging and use wireless charging instead. The question arises: is your device compatible with such technology? the smartphone from Samsung (for example, from the S or N line), then, in this case, your device will most likely be compatible, and a branded charger will go to it.

 The new iPhone 8 also supports wireless charging, although if you have an older iPhone model, you can also use this type of charging, first, you will need to buy a special receiver, such as the inside Qi2001.


Some Lumia, Motorola, Xperia, and HTC smartphones are initially compatible with Qi technology, as well as Nexus smartphones (Nexus 4, Nexus 5, Nexus 6, Nexus 7, Galaxy Nexus).
By the way, if your phone is not compatible with wireless charging technology, you should not worry too much - there are some spare options. For example, just connect the smartphone to the adapter, it will receive energy and transfer it to the smartphone with a cable. Check out the video below to find out how it works.
