Wireless charging for phone: how does it work, how to use it?

This article will tell about the wireless charger on the QI standard

In this article, you will learn what is a wireless charger for mobile phones, and how to use it.

Wired chargers lose their relevance every day, and high-tech wireless charging devices come to replace it, and some are charged with their gadgets using PowerBank. Thus, it can be said that only yesterday you were pleased with the wired charging of your smartphone, and now go to innovate the wireless transmission of electricity.

What is the BZU and what does it look like?

Once only dreamed about it. But today you can meet a rather huge amount of technologies that allow you to transmit electrical energy by air flow. It is worth considering that this procedure is in any case occurs either with a laser or through sound waves, as well as through any other physical phenomena.

But still, such a large-scale number of transmission technologies, makes an employee and practiced only one, which is actually used only in the production of these devices. Explain this technology works on the basis of studies Teslas and Faraday, Interest in the implementation of electricity transmission by air flow using electromagnetic induction.

Therefore, the studies that were conducted by them made a huge contribution to the technology of transmission of electrical energy, which was improved, as a result, a wireless charging for your smartphone can work now, and many devices that use electricity transmitted by air.

What standards have this technology?

Of course, each sphere has norms and denominations that are customary to call standards. The most common of them is the standard, the development of which is happening for 7 years, the company WPC (Wireless Power Consortium). The name of the standard is customary to call the Chinese word. "Qi"that if pronounce in Russian will be like "Qi".

Once this standard is distinguished by the fact that it is supported by almost all modern smartphones manufacturers. Now many airports, cafes, restaurants, clubs and other places practice wireless charging cell phones.

What is the principle of working wireless charging?

It should be assumed that the answer to this question is interested in all the inhabitants of mobile phones. It should be noted that the principle of its work is pretty simple and more or less understandable. The WPC standard assumes that the charging will occur only in the presence of special magnetic coils at the smartphone and the charging station.

Each coil has its own role, but nevertheless, one of them is a receiver of electrical energy, and the other is a transmitter of electrical energy. The exercise of charging for this standard is allowed at a distance of no more than 5 cm between the smartphone and the charging station.

Thus, if we talk about the efficiency (efficiency), then with wired charging it is 100%, and with wireless charging, if the phone will lie on it, it will be 75-80%.

What is the advantage and disadvantages of wireless charging?

Of course the biggest advantage It is that you will no longer need to insert and remove the cable from your phone. Despite the fact that this device is referred to as "Wireless", attach it to the outlet still have to charge the station itself.

Concerning disadvantages, they actually rest in the price range between wired and wireless charging, as well as charging the phone using a wireless charger takes place 2-3 times longer.

Does harm with health Wireless charging?

It should be noted that manufacturers of wireless charging devices according to WPC standard state that they do not carry any health hazard.

For clarity, you can bring the waves that radiates the sun, and by the way, the same waves are available in wireless charging devices, so worrying for their health when using wireless charging, it is at least paranoia.

What wireless chargers are popular to date?

Now wireless charging is very much, and they produce their huge number of companies under a different brand. Let's still consider which of them are tremendous and relevant to date.

Samsung Wireless Charging Pad

This device is the most recent model from the discharge of wireless charging. Charging is pretty universal, as it allows you to charge the phone regardless of how it lies on the panel itself. It also supports other technology standards, including WPC, AW4P and PMA.

PowerBot.

If you look viewing on the Amazon reviews, this device is the best wireless charging, which has many advantages at relatively with others, has a small whole. The price of this device on the Amazon website is about 10-15 dollars.

Nokia DT-910

Manufacturer Nokia MiG deserves confidence, including products from this company. The Nokia DT-910 wireless charger has a fairly affordable price, and at the same time has several advantages and additional functions, which makes the job better and better.

Decision to use or not to use wireless charging remains yours. But still some believe that this type of charging is worth using, since this option is much more convenient, and for it - future.
