- 1. What is Qi wireless charging
The world is becoming mobile and "wireless".
In the modern world, all file transfer manipulations using a smartphone happens "over the air". Internet access via wi-fi - at home, at work, in a cafe is taken for granted, and rarely anyone has difficulty using it. The time has come forwireless power transmission.
In 2008 was founded " Wireless Electromagnetic Energy Consortium" (Wireless Power Consortium, WPC), which brought together manufacturers from Europe, Asia and America. The goal of the "Consortium" is to develop a single standard for wireless charging technology.
Already in 2009 the company Palm provided the first phone to support wireless charging. Later, in September 2012, Nokia introduced 2 smartphones to the market - Lumia 820 and Lumia 920 also with qi standard support. Next, major smartphone manufacturers pulled up - Samsungg, Google Nexus(Asus, LG), Sony, etc.
Since 2014, our company Zaryadqi has been developing and distributing wireless chargers in Russia. Our store has the largest selection of wireless chargers and we are constantly monitoring new products and expanding our range. You will definitely find the right charger for you in our store.
- 2. Working principle
In plain language:
- The charger is connected to a power source.
- A magnetic field is created.
- The smartphone must support wireless charging - have a built-in receiver or the receiver is installed additionally.
- The phone is placed on the charger.
- Smartphone charging starts automatically.
From a technical point of view:
Energy is transferred from the transmitter to the receiver-receiver through an interconnected magnetic field generated by the flow of alternating current through the transmitter coil.
If the receiver coil is in close proximity, a significant portion of the transmitter's power lines will pass through the receiver coil, creating an alternating current in the receiver, which is then converted to a DC voltage. - 3. Benefits
Just. Put your smartphone on the Qi wireless charger and it will start charging automatically.
Modern. All major IT companies are already developing their devices according to the Qi standard.
Universal. Any device with a Qi receiver-receiver is charged by any Qi wireless charger.
Safely. The generated electric field is safe for humans and extends only 1 cm from the device.
Comfortable and convenient. There is no need for a bunch of wires that later get tangled or simply lost.
- 4. Phone models that have a built-in receiver-receiver and support wireless charging out of the box
More and more smartphone manufacturers are starting to integrate receivers into their top models: Apple iPhone XS, XS MAX, XR, X, etc., Samsung Galaxy S9/S9+/Note 9, Xiaomi Mi Mix 2S, Huawei Mate 20 Pro and etc.

- 6. How to use wireless charging
- 7. Types of wireless chargers
We conditionally divide wireless chargers into several types according to their functionality:
- . Standard charging stations in the form of a small "platform" on which the phone is placed, or charging built into the equipment - a lamp, clock, weather station, etc.
- . Wireless charging for use in the car: with special holders and brackets for the phone and adapters for the cigarette lighter.
- . Wireless chargers with stand function, i.e. The phone is at an angle during charging for convenient viewing of video, mail, social networks.
- . Wireless chargers with a built-in battery differ among themselves, in addition to design, in the number of additional usb ports and battery capacity - from 4000 mAh to 10000 mAh.
- . Wireless chargers for embedding in tables, cabinets, bar counters. They have a special design and protection against moisture and dust.
And also by scope or place of use:
- Home / office
- In the car
- On the road
- 8. There are receivers
- Embedded- already installed in the smartphone by the manufacturer.
If the manufacturer of your phone has not provided for the possibility of wireless charging, it can be easily adapted to this charging! For this, a special receiver film is used - there are several types of them:
- In the form that is installed under the cover of the smartphone. To do this, the phone must have special contacts.
- , which connects to the lighting power port on Apple and micro-usb on Android smartphones.

Description
The film is attached under the cover of the phone, the functionality of the phone is not reduced. The standard cable can be used at the same time as the receiver film is installed.
Such receiverqifor phones with special contacts Suitable for phones with dedicated wireless charging contacts: Samsung Note 4, Samsung Note 3, Samsung Note 2, Samsung Galaxy S5, Samsung Galaxy S4, Samsung Galaxy S3 and more.
The film is attached to the back of the phone. At the same time, it can be closed with any standard cover: made of leather, plastic, silicone - this will not affect the charging process. The connector, which is inextricably linked with the film, must be in the Lightning connector for Qi charging. The presence of a film receiver does not cause inconvenience.
Such Apple-receiverqi Suitable for Apple devices with Lightning connector: Apple iPhone 5, 5s, 5c, 6, 6s, 6Plus, 6SPlus, SE, 7, 7 Plus; iPad Air 2, iPad mini, and more (Apple does not currently support wireless charging without accessories)
Such universal receiverqi Suitable for any phone equipped with a USB connector for classic wired charging. The film is attached under the cover or case of the smartphone. The plug, inextricably linked with the film, for charging according to the Qi standard must be in the Micro-usb connector. The presence of a film receiver does not cause inconvenience.
On phones with a Micro-USB port, the connector can be one of three types, depending on its appearance, when you put the phone on top of the screen.
Connector type "C" appeared relatively recently - it can be found on a few devices. So, type "C" is equipped with MacBook 12", Samsung TabPro S, Google Nexus 6P, Microsoft Lumia 950 XL, ZUK Z1, Google Pixel C, Google Nexus 5X, One Plus 2, Acer Aspire Switch 10 V and other devices.
In addition to the above receivers, depending on the location of the connector in the phone, such film receivers may be suitable - they are called lateral or offset:
Accordingly, each type and position of the connector needs its own Universal receiverqi. By identifying the correct type of Micro-USB connector in your phone, you will buy the right receiver for wireless charging and allow yourself to forego wires!
- There are also: the receiver is already built into the case, so just put the case on your phone and it will be able to charge wirelessly.
You can always tell the manager of the online store your phone model - we will select the best receiver for you!
- 9. Difference between wired and wireless charging
Wireless charging produces a current of 1 ampere and a voltage of 5 volts. The standard power adapter that comes with the smartphone gives out from 1 to 2A. And when charging the phone from a computer (USB port), the phone is charged with a current of 0.5A (USB 2.0) to 0.9A (USB 3.0).
In this regard, you will not even feel the difference in charging time, or it will not be significant.
- 9. Energy efficiency
The energy efficiency of Qi wireless chargers is approximately 80%. It should be understood that it is simply impossible to achieve 100% energy efficiency; for standard wired chargers, this figure ranges from 75% to 95% at best.
- 10. Safety
Wireless chargers use non-ionizing frequencies that have no harmful physiological effects on humans. The Qi 1.2 standard includes the detection of foreign objects in the field of action of the charger, providing additional safety of use; Charging is only possible with Qi-compatible devices. Also, our chargers and smartphones have built-in safety mechanisms based on thermal control.
Do you have any questions?
Extending battery life is one of the most pressing concerns 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 need to remember to remember to leave 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 referred to as inductive charging. It uses an electromagnetic field to transfer power between two objects - a charging station plugged into a conventional wall outlet and a device that has a battery and related wireless charging hardware.
When they come into contact, the battery is charged, and if the contact is broken, then, accordingly, the charging stops.
The advantages are obvious: there are no wires and no need to carry around a charger and look for an outlet. It is also safe: for example, electric toothbrushes use inductive charging for many years, without fear that water and electric current will come 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 the installation of charging stations will probably be places such as Airports, hotels, restaurants, cafes and others. Instead of carrying around a charger and plugging it into a power outlet or computer, all you need to do is set up your phone and put it on the table and the phone's charge will start replenishing.
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 outcome is likely to be the same: one standard will win and only then will the technology be adopted into mainstream use.
qi(pronounced Qi) is currently the leading standard for consumer use and is supported by McDonalds, but PMA(Power Matters Alliance) provide greater business opportunities and include Starbucks among their customers.
qi
Qi is a standard developed by the Wireless Power Consortium, which was founded in 2008 and currently serves over two hundred customers 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 conventional smartphone charger.
Qi has gained popularity in large part 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 Rezence
PMA (Power Matters Alliance) was founded by Proctor & Gamble and Powermat Technologies in 2012. It has over 60 clients, including Samsung, Sony, Motorola and Microsoft.
The standard is also based on the inductive charging system, but in early 2015 the company announced its plans to merge with the A4WP standard, which uses diffuse inductive charging. This means that several devices can be charged at the same charging site at once. It also has the potential to charge over a long distance.
Future
In the near future, Apple will also have to decide in favor of one or another standard in order to tie 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 a decision and makes its choice. There is also a possibility that the company will offer its own solution.
The battle between standards is still going on, but Qi is by far the most popular standard in the consumer market, which means you'll encounter it more often than others.
What do you think of all this? write your thoughts in the comments.
Today, it is already hard for us to imagine our life without mobile gadgets. This has led to the fact that a huge amount of wires accumulate near household outlets, among which it is not so easy to find the necessary “charging”. In this case, a wireless charger will help solve the problem. The principle of its operation is very simple - just place the gadget on a special panel to charge it. The accessory is based on the principle of operation of the induction coil. This technology is called Qi. It has become very popular lately. In 2015, the globally popular brand began selling furniture that will have a built-in wireless charging module. Today, all flagship smartphones support Qi. It is expected that soon transmitters or, in other words, modules can be found at airports, restaurants, cinemas, fast food, shopping centers, which will allow charging phones and tablets at any time. In fact, this will make life easier for users of mobile gadgets. We are entering a new era where it is not necessary to carry around with you everywhere for all the devices we use.
Wireless chargers for Qi-enabled gadgets
The wireless power standard is called Qi. In Russian, the word is pronounced as "Qi". The standard bears such a name in honor of the term of Eastern philosophy. It is developed by the WPC Wireless Electromagnetic Energy Consortium. This organization brings together world electronics manufacturers and sets itself an important task - to standardize the process of charging gadgets using the induction method.
In the near future, all devices can be charged without being connected to the network. It's incredibly convenient. Each of us at least once faced with a situation where. We urgently need to find a way out. Soon, wireless charging modules will appear in all public places, as well as at every user's home. At home, you can simply place the module in a convenient place, and it will never get lost, unlike wired "charging". It is enough just to place a gadget on it and wait a bit until the battery capacity is replenished.
The principle of operation of wireless "charging" is based on the properties of an induction coil to transmit electric current. In the school physics course, we were taught that when an induction coil is connected to a power source, a magnetic field arises in it, perpendicular to the turns of the coil. Thus, if you place two coils within the range of the magnetic field and at the same time connect one of them to a power source, then voltage will appear in the second coil. In this case, it is important to take into account the fact that two induction coils should in no case be in contact with each other. Such a simple principle lies in the operation of wireless chargers that support Qi technology.
There are two varieties of the Qi standard. The first involves charging at low power - 5 watts, and the second - at high power - 120 watts. Qi high power is not currently produced by manufacturers due to objective factors. With Qi at 120 watts, you can charge your laptop. Qi at 5 watts is used to replenish the capacity and phones. It should be noted that different current strengths are required for a tablet and a smartphone. A wireless charger for a phone creates a current of 1 amp, and for a tablet computer - 2 amps. When choosing an accessory, be sure to pay attention to such characteristics.
Qi Energy Efficiency
A modern wireless charger consists of two components. One of them is built directly into a gadget that supports Qi and is called a wireless charging receiver. In fact, it is a receiver that conducts electrical current to the battery. The second component is called the transmitter. If the purchase of wireless “charging” is meant, we are talking about the transmitter. They come in a variety of shapes and sizes. The most common are round and rectangular transmitters.
To better understand how wireless charging works, it should be noted that the magnetic field is capable of transmitting not only electric current, but also data on bytes and bits, which was taken into account by the developers of the Qi standard. The interaction between the coils will only occur when the gadget with the built-in transmitter is close to the transmitter.
If the accessory for charging the gadget works in the background, then the pulse sent every 0.4 seconds by the transmitter will not change the voltage in the coil built into the transmitter. We can conclude that a modern accessory can recognize in which mode to function. As soon as a smartphone is nearby at a distance of several centimeters, the voltage in the induction coil will drop sharply, and the device will switch to active mode. As soon as the smartphone's battery is charged, the corresponding signal will put the charger into the background. It can be concluded that modern wireless accessories for battery replenishment are energy efficient.
Is Qi technology secure?
Some users mistakenly believe that the Qi wireless charging function can be harmful to health. The fact is that magnetic radiation is not ionizing. In its effect on the body, it is similar to a mobile communication signal, a radio signal. At the same time, the signal of the mobile network that comes from the tower is stronger and has a continuous character, while electromagnetic radiation disappears immediately after charging the smartphone battery.
The power of wireless chargers is 5 watts. It is not enough to have an effect on the human body. We can talk about a negative impact only if the power of such devices is 120 watts. But such models are not produced on an industrial scale. This explains the lack of wireless chargers for laptops. It is important to know that wireless battery charging technology has long been used in many models of electric shavers and electric toothbrushes, which once again proves its safety.
Which smartphones support wireless charging?
First of all, we want to note that not all gadgets today support the wireless charge function. Apple intentionally places products on the market that are not compatible with Qi. In this case, we recommend purchasing a special case with a built-in telecoil.
Flagship devices basically always support Qi technology. These include such popular smartphone models as Samsung Galaxy S6, Sony Xperia Z4v, Samsung Galaxy S6 Active, Google Nexus 6, Motorola Droid Turbo, Nokia Lumia 930, Samsung Galaxy S6 Edge. Already, dozens of models from various manufacturers can be charged using a wireless accessory, which provides maximum convenience for users.
Can you make your own wireless charger?
Wireless chargers are quite expensive, given that they are a conventional induction coil. The question arises: "How to make a module with your own hands?". In principle, if you have knowledge of the basics of physics and special equipment for measuring the strength and power of an electric current, this will not be a big problem. Fans of radio electronics are able to assemble devices that are not so simple, but we do not recommend ordinary users to conduct such experiments.
On aliexpress.com, you can find separately wireless device receivers for some smartphone models, including the Google Nexus line. It's easy enough to install on your phone. Under the cover of the device there are two contacts, which provide for a positive and negative pole. It is enough to buy and connect the receiver, after which you can conduct a wireless charging test. This solution is optimal if you somehow got a wireless charger, for example, you were presented with a gift, and your gadget model does not yet support the Qi function.
Wireless battery charging technology is gaining more and more popularity in the modern world. In the future, in many public places it will be possible to replenish the battery capacity. It is expected that stadiums, parks, restaurants, cinemas, fast foods will be equipped with wireless chargers. When buying smartphones, we recommend paying attention to the support for the Qi function, which is present in all flagship models in 2015.
Finally, you can get rid of wires once and for all: a new generation of mobile devices supports QI wireless charging technology. CHIP will tell you how it works.
Smartphone Nokia Lumia 920 on a QI wireless charger Smartphones, e-readers, tablets - many of us have been owners of these devices for a long time. Their batteries require regular charging, and this is quite troublesome. In many cases, this is a problem, since most smartphones run out of battery in one day. Therefore, it is long overdue to find a solution that takes into account both our forgetfulness and the constant need of mobile devices for electricity. Ideal would be a device, upon contact with which the gadget would immediately begin to receive a charge. To do this, the Wireless Power Consortium, which unites more than 100 IT companies, including Sony and Panasonic, has developed a single standard for wireless chargers. It is called QI (pronounced "chi"), which means "energy flow" in Chinese. The first version of the standard appeared in 2010, but the implementation of the technology was slow. It wasn't until mid-2011 that American provider Verizon began offering QI-enabled smartphones, including Samsung's Galaxy models. In 2013, the situation will change, which will be facilitated by the appearance of QI-smartphones in Russia: the new top model Lumia 920 from Nokia has built-in QI support, and for the Lumia 820, a back cover for wireless charging is optionally available.
Quick recharge for smartphones
According to the QI standard, the charging current for a mobile device should be no more than 5W. The standard does not provide for a specific method of energy transfer, but induction charging is currently implemented, while both the transmitter and receiver are equipped with coils. In the transmitter coil, which is supplied with alternating current, an alternating magnetic field arises. As soon as the receiver coil is affected by a magnetic field, an alternating current also appears in it. For the most efficient transfer of energy, it is necessary to ensure the best interaction of the receiving coil with the magnetic field. In this case, the optimal distance between the transmitter and receiver depends on the diameter of the coil. The size of the transmitter coil provided by the QI standard, depending on the design features of the transmitter, ranges from 30–80 mm. The required distance is approximately a tenth of this value, that is, both devices should be located close to each other. With increasing distance, the efficiency of energy transfer decreases catastrophically - from more than 70 to several percent. In addition, for optimal transmission, it is also necessary to choose a good position of the coils in space. According to the QI standard, this task will be performed by a magnetic core in the center of the transmitter coil, which will be attracted to the magnet in the receiver.
Magnetic field as a means of communication
The magnetic field, in addition to energy, also transmits information in the form of bits and bytes generated by phase modulation of the field. Communication between the transmitter and receiver is established at the moment when the mobile device, such as a phone, is on the surface of the charger. The transmitter sends a pulse every 400ms. If the voltage does not change, this means that no energy is being transferred. A voltage drop indicates the presence of a QI-enabled receiver. After detecting the last one, the transmitter sends out a stronger pulse to "wake up" the receiver. He, in turn, "negotiates" with the transmitter on the conditions of charging, that is, the required amount of electricity, strength and frequency of the current. After that, the power transfer phase begins, the effectiveness of which the receiver reports to the transmitter every 32 ms, sending him data packets with information about errors, which can be corrected if necessary. After the battery is charged, the receiver sends an “End Power Transfer” packet and the transmitter stops working.
The new version of the standard (1.1), which appeared in April 2012, provides for the use of more efficient chargers than the base standard. Version 1.1 has a good chance of success, but not all companies are involved in the development and implementation of technology: Apple does not support QI at all, and Samsung and Qualcomm are developing their own standard. Next year, Intel intends to launch ultrabooks with support for wireless chargers. To do this, the company will use not induction, but a resonant method, but it is still unknown whether it will be compatible with QI or not.
A technology has now become available that allows you to charge phones without using a cable. Its advantage is that this procedure is faster and easier, and you do not have to connect your smartphone to the network every time - just place the device on top of the wireless charging pad.
There are various competing standards for this technology. The most popular of these is Qi, which is today backed by companies such as Samsung, Google, and Nokia. However, more and more manufacturers are starting to use it in one form or another.
Which phones support wireless charging?
Some smartphone models have a built-in wireless charging function (their rating is presented below). Other devices will need to replace the back cover or case for this. Components for Qi are produced for specific phones, so if you connect them yourself, you should make sure that you select a compatible model.
If a dedicated wireless charging cover is not available for your smartphone, you can use a universal adapter that allows you to use this technology even for older devices.
What do you need to know about wireless charging?
As noted above, the current leader is the Qi standard, which is currently used in most Android devices. The technology works by using magnetic induction to allow energy to be transferred from the platform to the phone's battery. The Qi standard, whose name in Chinese means "air" or "spiritual energy flow", was created in 2008 and began to be developed simultaneously with the participation of 206 companies, including Microsoft, Samsung and Sony.
Speaking about which devices support wireless charging, we should also remember about the less common PMA standard. It also works due to magnetic induction, but its distribution area is somewhat lower. In June 2014, the developers of the PMA standard partnered with Duracell to place charging platforms in some public places in the US to promote the technology. If this idea proves viable in the future, it is possible that more smartphone manufacturers will start using this standard.
If we talk about which phone models support Qi-standard wireless charging, then the choice will be very large. Even if your Android smartphone doesn't have this technology built in, you can get a universal Qi receiver that only costs about $15. Despite the bulkiness, it will add significant convenience to you when using the gadget. The device attaches to the back of your device, which can then be placed on any Qi-compatible charging platform. Regarding the question of which phones support Qi wireless charging, it is worth noting that there is a receiver for the iPhone (5, 5s and 6 models) on sale, which also receives positive reviews. Its cost is about 30 dollars.
Which phones support wireless charging (list of gadgets)
Those who are interested in the new technology will find it useful to know the rating of devices that have built-in Qi standards.
The best known model in this regard is the one which is currently available for around $200. According to user reviews, this is one of the best Android devices in general. Also, this device is a leader in the use of wireless charging. The smartphone is compatible with both Qi and PMA technologies. With its elegant design, good performance and large 16-megapixel camera, this phone outperforms the iPhone in some ways. Commercially available Qi memory has a good long cable for connecting to the network. Its edges are illuminated with a light blue tint during charging and turn green when it is completed.
Among the devices that can charge wirelessly are the following:
- Samsung Galaxy Note Edge.
- Samsung Galaxy Note 4.
- Google Nexus 6.
- Motorola Droid Turbo and others.
Other Samsung models
Analyzing which Samsung phones support wireless charging, one cannot help but remember about this model. This model also simultaneously supports both standards - both Qi and PMA. The attractive curved shape of the case and the convenient screen allow owners to instantly access messages and other important data, and the built-in adapter does not impair the use of the device in any way. If the gadget itself can be purchased for about $300, the cost of the Pad to charge would be about $40.
Also belongs to this category of devices. This smartphone with an innovative curved screen offers very strong graphics performance on a bright display. Its screen size is much larger than other devices, so the battery consumption is correspondingly faster. In this model, the wireless charging capability is not integrated directly into the back of the phone, but a special Samsung Qi-enabled cover is available for sale that replaces the standard back of the device. This component costs approximately $25 and is available in two colors: jet black and snow white.
If you ask which phones support wireless charging in general, you will notice that this technology mainly affects gadgets with high hardware capacities, for which the ability to quickly charge them is especially important.
Based on this, it is not surprising that it is also equipped with the described technology. This gadget is characterized by high multitasking, fast and high-quality camera and high brightness of the screen, which has a size of 5.7 inches. In order to carry out its wireless charging, you will need a special case. It's available for around $30 and comes in two colorways.
However, Samsung is not the only manufacturer to massively use this technology. Which phones from other brands support wireless charging? Consider below.
Other brands
Google Nexus 6 has a nearly 6-inch screen and is equipped with a high-powered processor, so it especially needs the ability to quickly and quickly recharge. Qi technology is built in from the start, so there is no need to buy an additional cover or case. This gadget is quite expensive - about $ 500, but fans highly appreciate its hardware power along with Android 5.0. All this offers users a high level of comfort. Although there is no dedicated wireless charging platform, a universal accessory will do the job just fine.
Speaking about which phones support wireless charging, one cannot but touch upon a model such as the Motorola Droid Turbo. This smartphone with a screen of just over 5 inches has a camera with a resolution of 21 megapixels and many built-in features. Its battery life is approximately 9 hours under active use, so the built-in Qi technology is very useful. There is also a special charger for this model, which places the phone in a vertical position. This means that while charging, you can continue to use the device.
Sony brand
As already noted, the most actively new technology is used by manufacturers such as Samsung, Google and Sony. Which Sony phones support wireless charging? First of all, this is the Sony Xperia Z3 - a waterproof gadget that, with active use, works up to 12 hours without recharging. Its screen is high brightness, and the speakers provide loud chic acoustics. Despite the fact that its cost is about $ 400, the device is very popular. The wireless charging cover will have to be purchased separately and costs over $100.
Can you adapt your smartphone?
What phones support wireless charging without built-in technology? If your device does not natively support Qi, you can separately purchase and install an adapter on it and use the universal wireless charger. Depending on the brand of the gadget, you can connect the adapter via the micro-USB port (on the Android platform) or lightning (on the iPhone).
Universal wireless charging adapters
If your phone is not listed above, then you need a universal adapter and wireless charger. You can get them for phones with micro USB ports (like Android) and lightning ports (like iPhone). Thus, you can update and improve almost all devices available for sale. If we talk about, for example, which Xiaomi phones support wireless charging, then with the above method you will be able to charge even 5-year-old models without a cable.
Universal charger
Once you've made sure your phone supports wireless charging (by built-in functionality, using a special cover, or by connecting an adapter - it doesn't matter), you need to purchase a wireless charger.
Currently, there are many such Qi devices available in various sizes, shapes and colors. You can buy such a component not only for use at home or in the office, but also for a car, and even a Qi portable battery. If you have purchased a smartphone that supports wireless charging, it is advisable to choose a charger specially designed for it. If there is none, or you have updated your gadget yourself, finding a universal device is not difficult.
