Wireless charging technologies for electronic devices have been developed by manufacturers for a very long time. Perhaps the most familiar popular option for their actual use can be considered some models of electric toothbrushes. In this case, the advantage of this solution, in addition to the convenience of charging, is the absence of external electrical contacts, which are not very practical in a bathroom. It is also worth paying attention to the regular operation scenario of this device and the absence of the need to charge the brush in other places.
However, the smartphone market has not yet seen widespread use of similar solutions, which look very convenient. In our opinion, there are several reasons for this. The first two are quite typical for most new technologies: an increase in cost and a small number of available “response” parts - the wireless chargers themselves. But the more important reason is the significant change in the mobile device charging scenario. When using a cable, you lose only one thing - the ability to move your smartphone over a long distance. Moreover, in most cases this is not very significant (in addition, you can simply use a long cable). At the same time, you can continue to use telephone conversations, the Internet, mail, multimedia and all other applications. You can't do this with wireless charging. It necessarily requires the smartphone to be on a special stand while charging. Although, of course, you can imagine an option with a speakerphone or headset.
It turns out that in fact, wireless chargers may only be interesting in a limited number of scenarios - for example, in a docking station for charging at night or when navigating in a car. For frequent everyday or emergency use today, they are not very convenient. However, the option of chargers in cafes that are already being tested may also prove useful. Over the past few years, smartphones have received bright high-resolution screens with large diagonals and powerful multi-core processors, but the active operating time on a single battery charge has remained virtually unchanged. If they were able to guarantee that they would last more than a day, the situation would be different - the user would only need to use a wireless charger at home, placing the smartphone on it overnight. It should also be noted that for popular devices such as tablets, the use of wireless charging is less likely. In particular, they require a higher power supply than smartphones, and in addition, the stand will be too large. (By the way, it should be noted that during testing we found that in some combinations, a certain fixed position of the smartphone on the stand is required for operation.) The use of wireless charging with headsets or other accessories is also unlikely; the reason for the lack of such solutions will be the inability to use sufficiently large receivers coils in these devices.
In general, the following advantages of a wireless solution can be noted:
- no mechanical/direct contact;
- possibility of use in hostile environments;
- ease of use (in some cases).
However, there are also disadvantages:
- less efficiency;
- long-term charging;
- increase in the cost, weight and size of a smartphone;
- inability to fully use the smartphone while charging.
But we must admit that recently there have been certain changes in this area. Not every manufacturer, even the largest, has the strength to create a truly universal solution. It can be considered that standardization began in 2008 with the creation. The option they developed, called Qi, is today the only solution recognized by a large number of market players. In total, according to the consortium, at the time of writing, almost 200 companies were represented in it, and there were more than 350 products on the market that support this standard. Qi can be found in products from HTC, LG, Motorola, Nokia, Philips, Samsung and other manufacturers.
Another organization in this area is formed in 2012. Its member Qualcomm is currently offering its implementation of a technology called WiPower.
It is also worth mentioning, created in 2012, which also aims to develop and promote an industrial standard for wireless charging. Following him, a working group was organized in October of this year.
Currently, you can find Duracell Powermat products on the market, but they are not widespread and are not used by smartphone manufacturers, so later in this material we will consider Qi solutions.
Technically speaking, a wireless charger uses an electromagnetic field to transfer energy from one device to another. If we talk about the current Qi implementation, here in the low power section the following characteristics are set: distance of about 5 mm, maximum power 5 W. Let us recall that a power of five watts corresponds to the most common wired chargers with a USB interface and a current of 1 A. In addition to the coils themselves, the process involves special controllers that monitor the supply and reception of energy, and the controller is a unit installed in the mobile device.
Below we will look at three solutions of this standard from different manufacturers in terms of ease of use, charging speed and compatibility.
Nokia
Nokia offers two accessories to enable wireless charging of its devices: Nokia Wireless Charging Plate (DT-900) and Nokia Wireless Charging Pillow by Fatboy (DT-901). They differ only in design: the first is a strict device made of plastic, and the second is a soft and flexible “pillow”. Both models come in several vibrant colors to match the Nokia Lumia lineup. The remaining characteristics are the same: support for the Qi standard, an external power supply 12 V 0.74 A with a cable 1.8 m long.
In testing we used the DT-900. The stand body is made of plastic, in our case bright red. Its dimensions are relatively small - about 120x60x11 mm.
The upper matte surface has the manufacturer's logo in the center, around which there is a low rubber edge. It allows you to keep your smartphone on the charger. Note that the large dimensions of the panel roughly correspond to a smartphone with a 4.5″ screen diagonal. So modern large devices will cover it completely.
The edge and bottom surface are made glossy. On one of the short rounded ends there is a power supply input, and on the opposite side there is a white charging indicator. At the bottom of the panel there is a rubber insert that prevents slipping.
The included cable is red, but the power supply itself is white. It is worth paying attention to the parameters of this unit - it produces 12 V 0.75 A, which is significantly more than standard wired chargers produce. In particular, the standard AC-16 is designed for 5 V 1 A. It can be seen that the power losses are significant.
The list of compatible devices includes models from Lumia 720 and higher. However, only the Lumia 920 has a built-in receiver; for the rest, you will need to purchase an additional back cover, which communicates with the device through contacts located on the back of the smartphone. In particular, when working with the Lumia 1020, the cover increases the weight by 30 g and the thickness by about 2 mm. Perhaps this solution is more interesting than the built-in module in the Lumia 920. At least until such technologies are used everywhere.
The device turned out to be quite convenient to use. Its small size allows you to easily place it on a table, bedside table or shelf. The built-in indicator lights up during charging, which begins literally a couple of seconds after placing the smartphone on the stand. Please note that if you use large smartphones, this indicator may not be very visible. It is also worth paying attention to the non-standard power supply and connector. The other models reviewed in this article can be “transformed” into regular chargers and used with most smartphones by simply unplugging the Micro-USB cable from the cradle.
We conducted the first charging test together with the Nokia Lumia 920. The test showed that the wireless charger is capable of working even with a completely discharged device, which, undoubtedly, should be considered a plus of the solution. As for the time to fully restore the charge, with the DT-900 it turned out to be almost the same as with a standard wired power supply - about two and a half hours. So the charging speed in this case can be considered high, but the main thing is that it will be convenient for the user to predict the required time, since it does not depend on the option used.
Compatibility testing with the Samsung Galaxy S4, equipped with a proprietary wireless charging cover, was successful. The smartphone was able to fully restore its charge in about 3 hours and 10 minutes. It is also possible to start working with a completely discharged battery.
Note that Nokia has an unusual model of an external battery with wireless charging - Nokia Portable Wireless Charging Plate (DC-50). The cost of the Nokia DT-900 at the time of writing was about 2,600 rubles. Branded covers with receiving modules were offered for 1000-2000 rubles, depending on the model.
Samsung
Samsung chose a slightly different approach to packaging. Its S Charger Kit accessory includes a charging stand and a new smartphone cover with built-in charging circuits.
When used with the Samsung Galaxy S4, it increases the weight of the device by 20 g and the thickness by about 2 mm. It is interesting that the currents are indicated on the components: 5 V 2 A is required at the input (this is what the standard unit from this smartphone produces), but at the output you can only get 5 V 0.65 A.
The stand body is made of plastic. Its dimensions are about 161x91x12 mm. The top panel uses a gray semi-gloss material. Its concave shape helps to hold the smartphone in the desired position. The manufacturer's logo is visible in the center. However, if we talk specifically about the Galaxy S4, then it is noticeably smaller than the stand - the dotted line exactly corresponds to the size of the smartphone.
The main body is glossy white. In the center of one of the short ends there is a Micro-USB socket. To the side of it, on the upper edge, there is a green LED, which lights up when the smartphone is placed on the stand and charging begins. The location for the indicator is not very well chosen - it would be more convenient to see it on the opposite side. However, due to the large size of the stand this is not very significant. Most of the bottom is made of rubber, which allows the stand to stay firmly on the table.
The time to fully charge the Samsung Galaxy S4 is about three and a half hours. Testing the operation using a 1 A power supply showed that, in fact, the requirement for a two-amp model is not justified; a less powerful unit will be quite sufficient. This replacement does not affect the duration of wireless charging. Note that this configuration is also capable of restoring a completely discharged smartphone.
Let us remind you that when using the supplied wired charger, the charge recovery time is about two and a half hours. At the same time, up to 90% the charging speed is quite high, but at the last ten percent it decreases.
In domestic stores, this kit is offered for about 3,000 rubles.
PowerQi
The presence of a standard allows different companies, not just smartphone manufacturers, to produce compatible devices. In particular, we managed to find an almost “nameless” version of the PowerQI T-100 wireless charger for testing.
The package includes a stand, a power supply (5 V 1.5 A) with a Micro-USB cable and a special receiver unit. The last element is usually individual for each smartphone model; in our case it was the antenna and control unit for the Samsung Galaxy S4. The approximate cost on foreign trading platforms is $35 for a charger with a power supply and $10 for a receiver unit.
The stand is made of white glossy plastic and has dimensions of 150x80x10 mm. The flat top has slightly beveled edges and lacks any rubberized elements, so it doesn't hold the phone in place very well. The panel is painted in gray paint with the name of the company and model, as well as the logo of the wireless charging standard. The stand rests on four rubber feet.
The LED lights up green when there is external power, and when the smartphone is installed for charging, it changes color to blue. We also note that a sound signal sounds at this moment, which allows you to be sure that the device is recognized and charging begins.
The receiver unit consists of a flat antenna and a small board with a controller manufactured by Texas Instruments. It is supposed to be installed under the standard cover of the smartphone with connection to the contact pads present on the case.
Note that the output current indicated on the receiver is 600 mA. For smartphones that do not have this capability, there are options in the form of cases with connection via a standard Micro-USB. Interestingly, this antenna seems to be slightly smaller in size than the standard Samsung accessory; this may require more precise positioning of the smartphone on the transmitter. In our testing, this situation arose with the Nokia charger due to its compact size.
Charging time for a smartphone with a proprietary cover on a PowerQi stand is approximately 3 hours 30 minutes, so from the point of view of transmitters, these models are the same. Other combinations of receiver and transmitter give similar results, including the ability to restore the charge of a smartphone with a completely discharged battery.
Conclusion
Many companies today are showing interest in wireless charging technologies for smartphone batteries. However, no revolutions should be expected here. There are many players in the market, it is difficult for them to come to an agreement with each other, and in addition, the familiar “chicken and the egg” problem arises. So today, it’s probably not worth considering the presence of a built-in or optional wireless charging module as mandatory for top-end devices.
In this article we looked at several solutions developed according to the Qi standard. They showed good compatibility and were generally quite functional. The only cause of some concern is the relatively low possible power in this Qi modification, which does not allow for rapid charge recovery of modern devices with high-capacity batteries. However, if we consider these solutions as a night charger, they will be quite sufficient for most smartphones. As for active work scenarios, for example, navigation in a car, it is quite possible that the wireless docking station will not be able to restore battery charge while simultaneously running resource-intensive applications, but will only act as an additional power source, reducing the rate of discharge of the standard battery .
In any case, Qi technology can be considered already quite mature and suitable for use not only by enthusiasts, but also by ordinary users who find this scenario useful for themselves. Moreover, it is not at all necessary to use original accessories - solutions from lesser-known companies offered on Internet sites at a relatively low cost may also be suitable.
In short: you can take it!
The purpose of this review is to provide basic technical specifications, not to write a novel. I got B's in Russian and literature, but I didn't like essays. If you find any errors, write to me and I will correct them. And in general, as the Chukchi would say: “It’s yours to want to buy a product, mine is yours to write a review.”
Background. Order
I decided to get a wireless charger for my Chinese phone (a Samsung Galaxy Note II clone). I chose the cheapest options. As a result, I ordered separately a universal charger and a receiver with a micro USB connection. They arrived in regular bubble bags. A white USB cable, 80 cm, is included with the charging transmitter.

Testing:
First of all, I decided to measure the current during normal charging of the phone. For this I used a popular USB tester and the Ampere program. To my surprise, the data turned out different. I don’t know what to blame, perhaps the program makes incorrect measurements.
I don’t know who to believe, but I will rely on the program’s readings.
In Standby mode, the red LED glows barely noticeably, the tester shows zero current consumption (in fact it is less than 50 mA, there is nothing more precise to measure). Therefore, you can safely leave the charger in standby when there is no need to charge the phone.
When you put the phone down, charging is activated and a moderately bright blue LED lights up.
In charging mode, the transmitter consumes about 780 mA (according to the tester).
The phone receives about 540 mA (according to the program).
For my phone, the difference is not big, so it doesn’t take much longer to charge wirelessly. For those whose phone directly consumes about 1 A, for those the wireless option will take twice as long. During operation, the charger and the phone do not heat up significantly, it feels warm, about 30-40 degrees.
A few words about the receiver.
Achtung! When purchasing, pay attention to which direction the micro USB connector on your phone is facing. On aliexpress I came across the receiver in two variations.
The thickness of the receiver is not uniform. The main area has a thickness of 1 mm, at the location of the microcircuit it is 1.45 mm (measured with a caliper). Fits my phone perfectly. The lid closes tightly and nothing sticks out. True, I had to cut off the latch on the inside so as not to crush the cable. The cable is very thin, only 0.2 mm. I can’t show you photos with the phone, because the only camera is the phone itself.
At the end of the charge, the transmitter continues to glow, consumes about 600 mA and remains warm. Since the phone stops consuming energy, everything goes to the unwanted electromagnetic field.
Total:
Pros:
- Cheap
- Universal
- Quite thin receiver
- There are no problems with positioning; charging does not stop if the receiver and transmitter are slightly shifted.
Minuses
- No automatic shutdown at the end of charging
- Short USB transmitter cable, only 80 cm.
- The receiver outputs about 500 mA, instead of the stated 1000 mA.
- USB is constantly busy. To connect anything to the phone, you have to remove the cover. It will be difficult to charge your phone via cable. To transfer files you have to use Bluetooth or WiFi.
I'm happy with the purchase, now I don't need to reach for the cable and try to get into the phone connector in the twilight. I recommend it to everyone for whom charging time is not critical.
P.S. No cats, dogs, cockroaches or other pets!
I plan to buy +17 Add to favorites I liked the review +10 +23It would be great if you never had to charge your smartphone, or if it charged without any contact while connected to a Wi-Fi hotspot. Unfortunately, today no manufacturer can promise you this, but there is a way to forget about the need to connect a charging cable. We are talking about the so-called. Today, the Qi standard is actively developing, and many devices already support it. Let's figure out what it is and whether we should use it.
What is this?
So, as already mentioned, wireless charging allows you to top up your device's battery without connecting a power cable to it. However, a charging contact is still needed, and the device will not start charging until it is placed on a special charging platform or mat. Some devices natively support wireless charging technology, and the necessary elements are built into the case, and some devices can be taught to charge wirelessly using a special case, which, however, seriously increases their size.
Supported devices charge using induction, which means the element needed for wireless charging is nothing more than a coil that is charged using electromagnetic fields. This process occurs unnoticed by the human eye. The only thing you will see is a battery charge indication on the smartphone screen.
Why is this necessary?
In fact, using the charging cable is not convenient enough. Cables become frayed, tangled, and lost. It is much more convenient to have a platform that is always in one place, at home and at work. The Qi standard is widespread today, and today wireless chargers can be found in cafes, hotels and many other places. This is more convenient than looking for a socket and cable suitable for your smartphone.
Finally, the last and most unobvious advantage can be appreciated by owners of devices protected from moisture. When there is no need to connect the cable, there is no need to open the plug on the case, which wears out quite quickly and is not very convenient.
What are the disadvantages?
I would like to say that there are none, but this is not so. The main disadvantage of wireless charging technology is that it is less energy efficient. The smartphone will not charge as quickly as when connecting a cable, and the electricity will be spent less efficiently, and some of it will be lost in the form of heat. However, slow smartphone charging should not bother you if you can always place your smartphone on a mat at home or at work.
Another disadvantage is the rather high cost compared to conventional chargers. This is a more complex technology, and this leads to another nuance. Wireless charging is quite difficult to integrate into a device that is too thin.
Which devices support wireless charging?
Almost every modern device supports wireless charging, but some, like the iPhone, won't charge without an additional accessory. Devices from Asus, Google, BlackBerry, HTC, Cat, LG, Kyocera, Motorola, Nokia, Samsung, and Yota Devices support wireless charging. A complete list of such devices can be found here.
Based on materials from AndroidPit
Extending battery life is one of the most pressing issues for all smartphone owners. At the moment, some of our devices can offer up to a week of battery life, but most smartphones cannot last even a day, and charging on the go is still a reality and a challenge for all of us.
The good news is that we may no longer have to remember to remember the charger every time. The era of wireless charging is almost upon us.
What is wireless charging?
The most common form of wireless charging is often called inductive charging. It uses an electromagnetic field to transfer energy between two objects - a charging station connected to a regular outlet and a device that has a battery and associated wireless charging equipment.
When they come into contact, the battery is charged, and if the contact is broken, then charging stops accordingly.
The advantages are obvious: there are no wires and there is no need to carry a charger and look for an outlet. It's also safe: electric toothbrushes, for example, have been using inductive charging for years without fear of water and electricity coming into contact.
Now this technology has made its way to smartphones and other mobile devices, and wireless charging is becoming more and more mainstream.
Objects for installing charging stations may include places such as Airports, hotels, restaurants, cafes and others. Instead of carrying a charger and plugging it into an outlet or computer, all you have to do is set up your phone and place it on the table, and your phone's charge will begin to replenish.
But before this happens, issues with standards must be resolved so that all devices and stations do not have compatibility problems.
Wireless charging standards
Like all relatively new technologies, wireless charging has several competing and incompatible standards. While it won't be as exciting as the battle between BluRay and HD DVD 10 years ago, the result will likely be the same: one standard will win and only then will the technology be adopted into widespread use.
Qi(pronounced Qi) is the current leading standard for consumer use and is supported by McDonalds, but P.M.A.(Power Matters Alliance) provide greater business opportunities and count Starbucks among their clients.
Qi
Qi is a standard developed by the Wireless Power Consortium, which was founded in 2008 and currently serves more than two hundred clients such as Microsoft, Google, HTC, Sony and Samsung.
Qi is an inductive charging system that uses tightly twisted wires to produce and receive an electromagnetic field. The power of the Qi standard is 5 W - the same as that of a regular smartphone charger.
Qi gained popularity largely thanks to Google and Android device manufacturers.
Also recently, the furniture company Ikea announced new products: tables, lamps, etc. with built-in Qi charging.
PMA and Review
PMA (Power Matters Alliance) was founded by Proctor & Gamble and Powermat Technologies in 2012. It has more than 60 clients, including Samsung, Sony, Motorola and Microsoft.
The standard is also based on an inductive charging system, but in early 2015 the company announced its plans to merge with the A4WP standard, which uses distributed inductive charging. This means that several devices can be charged at once on one charging site. It also has the potential for long-range charging.
Future
In the near future, Apple will have to decide in favor of one standard or another in order to attach them to iPhone smartphones; it’s only a matter of time. Apple hasn't always been interested in standards, but it can tip the scales one way or the other if it makes up its mind and makes its choice. There is also a possibility that the company will offer its own solution.
The battle between standards is still ongoing, but at the moment the Qi standard is the most popular in the consumer market and this means you will encounter it more often than others.
What do you think about all this? write your thoughts in the comments.
Hello, dear readers. I'm sure you've heard, at least remotely, that you can charge your phone without using wires. Surely many dismissed it, thinking that such modern technology is only available in very expensive devices. But no.
Almost any phone supports wireless charging, although with some caveats. Branded smartphones can receive energy through the air right out of the box, but for others you will have to purchase special accessories. Today you will not only find out whether your mobile phone supports wireless charging, but also how to ditch the wires if your device is outdated.
Wireless charging – what is it?
Photo: Koolpad QiBefore considering smartphone models that are equipped with wireless charging, you need to understand its essence. In fact, wireless energy transfer is not such a complex technology as it seems at first glance. In technical terms, wireless charging is represented by two copper coils.
One plays the role of a transmitter of energy, which it receives from the electrical network. The coil is installed in the docking station (the platform on which the smartphone is subsequently placed). The second coil is the receiver. It is equipped with devices that require energy, such as mobile phones. As a rule, the receiver is hidden from view inside the case, unless it is external.
The device's battery receives energy thanks to the magnetic field that occurs when the receiver is in the field of action of the transmitter (usually about 4 centimeters). This principle is true for the Qi standard, which is most actively used in wireless charging of wearable devices.
Smartphone with Qi icon supports wireless charging
The Qi standard was developed by the Wireless Electromagnetic Energy Consortium to transmit energy over a distance of up to 4 centimeters. Scientists, when creating the standard, used developments that had already been made by many other specialists.
In general, the idea of transmitting energy over a distance appeared two centuries ago, when Marie Ampere discovered a law proving that electric current produces a magnetic field. A significant contribution was made by Nikola Tesla, who built a tower to demonstrate wireless energy transfer. Subsequently, many organizations and scientists studied technologies, but a large percentage of experiments ended in the early stages.
Until this century, wireless energy transmission remained at the testing level. So far, the technology has not become interesting to large manufacturers of portable electronics. In 2009, after the creation of the Qi standard, which became the most suitable for use in wearable technology, a number of companies began to develop concepts that support wireless charging.
The impetus for companies was the fact that the standard was free and accessible. Today, almost every flagship smartphone boasts the presence of technology, and budget smartphones boast accessories that make the function work for them.
Not a dozen companies are working on energy transmission technologies other than electromagnetic induction. For example, students at the University of Pennsylvania conducted an experiment in 2011 in which they proved that energy can be transmitted through ultrasound. And in 1945, Soviet scientist Semyon Tetelbaum described in an article the possibility of transmitting energy using microwave radiation. Subsequently, this technology was actively developed. Energy can be transmitted with a laser beam, which NASA has proven in experiments. Nikola Tesla, known for his experiments with electricity, even believed that it was possible to create a worldwide wireless system that would save people from power lines.
List of smartphones with built-in support for wireless charging (2019)
Well, you are now familiar with the theory and history of wireless energy transfer, it’s time to move on to devices that support the technology. Speaking of support, we include in the list devices that received a receiver already at the factory (you can install it separately).
To date, more than 80 smartphones have received wireless charging using the Qi standard, not counting a number of smart watch models and other devices. And this figure is growing at an enviable rate. I will try to list as many models as possible - the exact list, which is regularly updated, is presented on the Qi portal.

This is not a complete list - there are also a number of models from lesser-known companies. Don't be surprised that the popular iPhone isn't on the list. It's not a mistake. Apple has not yet officially integrated wireless charging into its products. But there is a way out, more on that below.
The smartphone models presented in the list only require the presence of a platform that is necessary for transmitting energy. As a rule, it is included with the mobile device, but not always. In this case, you will have to purchase a docking station separately.
Usually, the manufacturer produces a branded model, but you can use others - there is no special connection between the smartphone and a specific site. You can even order a cheap “noname” docking station, which in most cases will satisfy the buyer’s needs.
What to do if your smartphone does not support wireless charging
If you don’t find your device in the list of supported smartphones, don’t rush to get upset. There is an exit. More precisely, there are two of them. So, perhaps your phone is among those for which receivers (small plates with a built-in circuit) for wireless charging are specially produced. This list includes quite popular, but rather outdated models. There are exceptions, such as the iPhone 7.
Both popular and not outdated, and the manufacturer did not integrate the receiver. Receivers designed for certain models receive the appropriate designation, as well as the necessary characteristics. For example, similar receivers for the Samsung Galaxy S 5 or older solutions have unusual contacts that match those found under the device cover. Here are the most popular models that received special receivers:
- iPhone: starting with “four”.
- Samsung Galaxy: S3, S4, S5; Note 2, 3, 4, Edge.
- LG: G4, V10.
- Sony: Xperia Z3+/Z4; Experia Z5; Experia Z5 Premium.
- Huawei: Ascend Mate 7, Mate S.
The receiver for these devices usually comes with a docking station. You can buy parts separately - there is no special connection. In addition to boards (receivers), there are also special cases on the market for wireless charging of devices, which contain a copper circuit inside. For each smartphone, a correspondingly shaped case is made.
Universal Solutions
There are more and more devices that support wireless charging, but manufacturers are in no hurry to “import” the technology into the budget segment. And he is the most popular. Especially cheap smartphones are loved in China, where they came up with the idea of producing universal receivers for any model.
A docking station + receiver set costs about 500-700 rubles (you can find it cheaper), the main thing is to choose the right one for your smartphone. Pay attention to the shape and connector. A universal receiver can be found for almost any smartphone.
Docking stations

Unlike receivers, which are either hidden inside the phone or are a faceless plate, docking stations allow the user to choose the model they like. Some companies even provide original solutions that will become part of any interior.
Particularly popular is the wireless charging dock from Samsung, made in an oval shape. It is suitable not only for charging the company’s smartphones, but also for most other models.
Among the features, it is worth highlighting support for automatic shutdown when the device is fully charged, as well as light indication. The average cost is 2,000 rubles, but in Chinese online stores you can find a cheap replica for 400-700 rubles.
The Woodpuck FAST Edition Bamboo playground model, which is made of wood, is also interesting. The manufacturer, so to speak, has combined modern technologies and natural materials. The functionality is no different from other docking stations, but it looks catchy. Cost – 40 dollars.
But Aukey QI boasts compact dimensions that allow you to take the charger with you. Yes, and the price is low - $30. Fans of purchases from China have huge catalogs to choose from, in which it will not be difficult to choose a cheap and beautiful docking station.

It is made in the form of an oval platform on which the smartphone is placed for charging. It even has a backlight. Asus, following modern trends, has made the new device not only beautiful, but also useful. True, the price is steep.
Bottom line
It's safe to say that the list of devices that support wireless charging will only grow. A technology that can eliminate a lot of wires is of interest to both the user and the manufacturer, who receives additional income for its presence.
In a couple of years, every smartphone will probably support wireless charging. In addition, a dozen companies are working on developing even more advanced technology that will not be tied to a docking station. We, ordinary users, just have to wait a little to forget about the main problem of portable devices - being tied to a power outlet.
