Technology makes life easier for the modern user mobile devices in a variety of aspects. Until recently, the main competitive positions were concentrated in the devices themselves, but today manufacturers are paying more and more attention to accessories and peripheral components.
One of them is how it works this device and how it can be useful to the modern user? The answers to these questions lie in the very concept of communication, which excludes a wired connection. Wireless contact is designed to save people the hassle of inconvenient connectors. In many ways, this idea was realized, but there were some shortcomings of such devices.
Features of wireless chargers
In the early years of the spread of telephones for cellular communication manufacturers had to make reservations when positioning such gadgets as mobile. The fact is that they were and remain mobile only conditionally, since there is a dependence on the charger cable. Wireless charging allowed to remove all the conventions of such designation of mobile phones and smartphones.
How does this device work? All the technologies on which such charging is based are based on the principles at a distance. It is important to note that the spread of technology wireless communication and the transfer of information is not something new and surprising for a long time. Radio signal modules, Bluetooth and Wi-Fi sensors, network access points - all this, to one degree or another, allows you to transmit information signals.
However, the novelty and fundamental difference with wireless principle actions are precisely in the possibility of transferring energy at a distance to power batteries.
Principle of operation
The most common design of such devices provides for the presence of induction coils in the filling. In fact, they perform the function of receivers, as well as translators of electrical signals. When the charging itself is connected to the mains, a voltage is formed, after which a magnetic field is formed around the transmitting coil. Actually, after entering this field of the phone, wireless charging is also activated.
How does recharge work? Through the transformation electromagnetic waves, which are transferred to the battery already as electricity. In this case, the target object for power can be not only a phone or smartphone. The developers are guided by the broad standards of batteries and batteries, which also cover some models of tablets, cameras, players and other equipment.
Depending on the model of the device and its characteristics, different conditions for maintaining charging are possible. For example, to understand how it works, you should familiarize yourself with the Qi power transmission standard. Such a transmitter is capable of replenishing the battery capacity at a distance of 3-5 cm, that is, practically a mobile device must be in contact with the charger.
Wireless Charger Safety
The ability of chargers to transmit energy over distances rightly raises questions about their safety for users, who in any case will be in the area of \u200b\u200binduction coils. However, manufacturers claim that such devices do not cause any harm to health.
Examples are electric shavers and brushes that operate on the same principle of electromagnetic fields as wireless phone chargers. How does the charging panel work in contact with other equipment and does it harm it? This issue is also raised, but the manufacturers deny such a danger.
The fact is that the maximum power at which such devices operate is no more than 5 watts. This is not enough to have a negative impact even on devices that are sensitive to electromagnetic fields.
Devices from Samsung
One of the most successful developments in the Korean wireless charging segment is the Wireless Charging Pad. This is an optimized version of the base family that has fixed common issues with most similar devices first generation. One of the main advantages of this model is the ability to interact with the phone's battery, regardless of its position relative to the functional area.
In the commercial form, this version is represented by wireless charging for which supports the WPC standard. This technology differs in that it is suitable not only for Galaxy smartphones, but also for most other Samsung phones. In addition, according to the manufacturer, charging can replenish energy to half the capacity in just a few minutes.
Apple devices
It must be said right away that “apple” products do not support wireless charging technology. However, the manufacturer is looking for alternative ways provide this opportunity to its users.
In particular, he recommends using accessories in the form of covers from Duracell. Therefore, the question of whether wireless charging works through a case, in the case of iPhones, will have a positive answer. If this method does not suit you, then you can use the iQi format receiver card. It connects via a special Lightning connector and is also hidden under a standard smartphone case.
Devices from Cota
Interesting proposals are also developed by Cota employees. They are not just mastering the concept of specialized charging pads for mobile devices, but are striving to expand the range of their field of action as much as possible. For example, in addition to phones and tablets, wearable electronics can be filled with energy with such a device. Moreover, for this it is not necessary to bring the device close to the active panel.
A small device the size of a bread box works at a distance of 10 m. The question arises: "How does wireless charging work with such a radius? Is it efficient enough?" And here it is worth returning specifically to wearable equipment, among which: smart watch, bracelets and wristbands, since it is in working with these gadgets that the device shows the most impressive performance. Obviously, it takes more time for phones and smartphones.
Disadvantages of Wireless Charging
Like all technologies that radically change approaches to the use of technology and electronics, wireless devices for charging have a lot of disadvantages. Of course, the user gets a significant advantage, since he does not have to fiddle with wires and connectors, but the efficiency of filling the power supply with this method is noticeably reduced.
Most devices provide a charge in a longer period of time compared to the classical method. In addition, there are ergonomic inconveniences that modern wireless charging cannot yet get rid of. How does a wired charging system work? It requires connection to the device, after which it can be used for the very 30-60 minutes required to replenish energy. However, in the case of wireless technologies, not only does the charge time increase, but the possibility of using the device during this period is also excluded.
Directions for further development
Actually, all directions of development of chargers that work without wires are focused on eliminating the above disadvantages and, in general, improving the basic characteristics.
Also a big problem is the considerable weight of such devices. In the middle segment, an ordinary device is a platform that can hardly be called mobile. However, here it is worth noting how the Samsung S6 wireless charging and devices for younger versions of the smartphone from the Charger Kit line work. These are panel charging accessories that are fixed to phones like protective devices and covers. This interface configuration minimizes the size of the charging infrastructure, but is not very efficient either.
Conclusion
This is not to say that the advent of wireless chargers has caused a stir in the market of accessories for mobile devices. Despite the novelty of the concept, the distribution of these products is hampered not only by ergonomic flaws, but also by the cost at which wireless phone charging is sold.
You can make a similar device with your own hands at a lower cost. To do this, it is enough to organize a blocking generator with the function of an energy transmitter. As experienced craftsmen note, such a circuit will require only a home-made copper-based coil and one transistor with an accompanying wire infrastructure. Another thing is that in terms of reliability and security, such a device will noticeably lose to the same branded models from Samsung.

When it comes to products that support wireless charging, you need to understand at least a little what it is. Let's just say - no, the current is not transmitted through the air. The charger itself must in any case be connected to the mains.
Wireless charger- this is a way to charge your device without using wires, but the smartphone must be placed on a special plate. Instead of plugging a cable into the appropriate jack, you simply place your phone or smartwatch on a dedicated stand and it instantly starts charging.
A dedicated charging platform is a very important part of this process. In wireless charging, a mandatory part is a magnetic coil of wire built to transfer energy from a source to a receiver (smartphone).
When both coils line up in parallel and as close as possible to each other, energy is transferred to battery through a process called magnetic induction. Once the coils are no longer in contact, the power transfer stops and the phone no longer charges. Everything is pretty simple.
A phone with wireless charging, budget or top, in any case, will meet the following principles:
How wireless charging works
Wireless charging phones have become very popular in 2018. The technology uses two resonant inductive connections to transmit low power signals between two devices. They are specially designed to transfer electricity without touching each other, while charging the device in the same way as a wired power supply.
The base station, which is connected to the electrical network through its own cable, has a transmitter coil, and your phone has a receiver coil. The source regularly sends out a signal, and when the receiver coil is close enough, there is a change in resonance ( base station changes the amplitude of its oscillation, a wave resonance is provoked), electromagnetic induction occurs. Next, the waveform is modulated (changed so that the coil in the phone "knows" that power is being sent to it), and inductive charging of the smartphone battery begins.
Fun fact: Wireless charging uses the same electrical theory as an electric generator: mechanical energy creates electrical energy.
Inductive charging uses these two specially designed electromagnetic coils to create magnetic field between two devices. Next, a more complex process occurs that allows the magnetic field to generate electricity through potential differences and oscillations. An oscillation is a temporary repeating variation, and in the case of an electromagnetic coil, you may encounter this concept in another interpretation - vibration, which in fact will not be a distortion of meaning. Now the coil on your mobile device, connected to the battery charging circuit, is being charged using the energy caused (generated) by the magnetic field.
Electromagnetic induction occurs only in the spiral axis of the coil, and if you start moving the coil or winding (one, relative to the other), in the presence of a magnetic field, electrons are formed on the winding, i.e. current. Electromagnetic induction is also used in transformers and current meters.
Android devices with wireless charging
This technology has existed for several years, but, unfortunately, it is still not very popular. But time is ticking and various big companies are starting to build new wireless charging standards though regular user believes that only the iPhone 8 and iPhone X have this. But this is not so.
Many popular phone manufacturers are starting to embrace this technology, and if you're considering buying your next gadget with this feature, here's a list to help you figure out which phones support wireless charging:
If your phone is on this list, you just need to buy a wireless charger. Which Samsung models support wireless charging is indicated above.
note
You do not need to purchase a wireless charger from the same company as your phone, such as a gadget for Samsung devices Works great with iPhone X too.
Which iPhone models support wireless charging?
Wireless charging is one of those features that Apple technology developers have only recently added to their devices. Now you can buy an iPhone, Apple Watch and Qi-enabled AirPods.
Although Apple launched a very powerful campaign to advertise its iPhone with support for wireless charging, in fact, there are not so many models that support this feature from the brand:
- Apple iPhone 8
- Apple iPhone 8 Plus
- Apple iPhone X
- Apple Watch
- AirPods
That being said, wireless charging is generally not as fast as a traditional wired power supply. But the advantages of using this feature become visible immediately after purchasing the phone.
Are all wireless charging systems the same?
No, and this is where things get a little more complicated. Phones with basic wireless charging have been around for a long time (again, it wasn't invented by Apple), and there are now many standards that govern how wireless charging works for a particular smartphone model. The two most prominent developers of this technology are the Wireless Power Consortium and the Power Matters Alliance. These organizations maintain specifications called Qi and PMA.
Apple has designed all of its wireless charging technologies around the Qi standard, but not all devices from this company work in a single version. Some of Apple gadgets devices that include wireless charging, such as the Apple Watch, use a special version of the Qi standard that allows Apple-approved chargers also use Apple Watch.Apple: iPhone 7, iPhone 7 Plus, iPhone SE, iPhone 6S, iPhone 6S Plus, iPhone 5S.
This is a list of the most popular models that are most frequently asked about Qi support. Does the iPhone 7 (Plus) support wireless charging - as you can see from the list, no. If your phone is listed or not listed above, then you need a universal adapter to be able to use Qi technology. You can connect them to your smartphone using the Micro-USB port (for example, for Android smartphones) or using the Lightning port, (for example, for iPhone).
Of course, you have the choice of an internal adapter that fits under the case cover, directly on the battery, or on the case itself, under the phone case. In this case, a small adapter plug will hang outward, which is connected instead of a cable to the charging connector.
Here are two of the most common and sought after external wireless charging adapters for any phone: Micro USB(Android) KSIX aircharge and Lightning (iPhone) Choetech aircharge combine. Once you've installed an external Qi-enabled adapter on your phone, all that's left to do is buy the charger itself.
Do you want to know which Samsungs support wireless charging and whether your smartphone has this capability? Let's take a closer look at which Korean company phones support this wireless feature.
This company was the first to offer customers to charge their devices wirelessly, over the air. First this technology from the Koreans appeared at various exhibitions a couple of years ago and still Samsung does not change itself. However, not every device of the company boasts the function of replenishing the battery charge by air. In this article, you will learn about all the models of the company with the implemented technology for transmitting energy through the air.
Samsung Wireless Charging Support: How Does It Work?
After looking at the main competitors from Apple Corporation, Samsung engineers decided to implement their own Qi interface.
In total, the company's smartphones have support for two standards - Qi and PMA. The first is newer and has a faster battery charge rate. However, it is found only in flagship devices that many users cannot afford.
What else is there besides Samsung - you will learn from another article.
Samsung Wireless Charging Supported Models
Let's highlight the list of phones that support wireless charging from Samsung:
- for the first time, Qi support appeared already in the fifth generation of the Note phablet;
- galaxy S6 generation;
- extended version of the Galaxy S6 Plus;
- version with a curved screen galaxy S6 Edge;
- the latest generation of the galaxy S7;
- galaxy version S7 edge.
Now you know what Samsung phones support wireless charging and you can choose the device that suits your needs and capabilities. However, all the listed phones are flagships and their price tags differ slightly.
In the next section, you can read material about how well Qi works and much more.
Technology does not stand still. If earlier the ability to charge a device wirelessly seemed like a fantasy, now it is a reality that will be present in all smartphones in the near future. But today the number of mobile devices that support this technology is extremely small. In order for you to get acquainted with the best of them, we present to your attention a rating in which we have collected the best phones with wireless charging.
