Devices that support qi technology. Qi wireless charging - what is it? what for? how is it used? and how to quickly charge your Galaxy S7. ➕ Benefits of wireless chargers

They have the ability to charge wirelessly: the flagship model charges over the air "out of the box", and for the Lumia 820 you need to purchase a replacement case with wireless charging capability.

The world has already been shown devices with wireless charging, for example charger Touchstone for Palm Pre, Powermat for iPhone, Energizer induction chargers. But unlike these chargers, created according to our own specifications, and therefore incompatible with other devices, we use the Qi standard - the only globally accepted wireless charging interface for devices created by the Wireless Power Consortium, which consists of more than 100 different companies.

Qi standard designed to transfer energy various devices using magnetic induction. It is technically very similar to the solution used to charge electric toothbrushes.

How it works?

In simple terms, the base station consists of an induction coil that generates an electromagnetic field when alternating current... The device to be charged contains a similar coil capable of trapping this field, converting the received energy into direct current, which is used to charge the battery.

If we consider the process in more detail, then in wireless charging the transmitter ( transmitter) consists of a current transformer ( ac-dc power converter), master devices ( drivers), transmitting coil ( transmit coil), potential and current sensing ( voltage and current sensing) and controller ( controller). Receiver ( receiver) contains a receiving coil ( receive coil), rectifier ( rectification), voltage regulator ( voltage conditioning) and controller ( controller).

Energy is transferred from the transmitter to the receiver through an interconnected magnetic field that occurs when alternating current flows 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 direct voltage.

You can watch an interactive presentation with a detailed description of the technology on the WPC website.

The charger can consist of several transmission coils that are activated depending on the position of the device to be charged on it.
The Qi standard supports the data transfer protocol between chargers and rechargeable devices at a speed of 2 kbps. Now, via this protocol, information about the required level of electricity for a full charge is transmitted from the device being charged, as well as messages that the device is charged.

Energy efficiency

The energy efficiency of Qi wireless chargers is approximately 80%. It should be understood that it is simply impossible to achieve an energy efficiency of 100%; for standard wired chargers, this figure ranges from 75% to 95% at best.

Safety

Regarding the safety of wireless chargers, we can declare that we use non-ionizing frequencies that do not have any harmful physiological effects. Qi 1.1 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.

The future of wireless charging

Following the publication of the low-power (five-watt) Qi specification in August 2009, in 2011 the Wireless Power Consortium began work on expanding the specification to medium power, allowing power to be increased to 120 watts. Despite the fact that the first specification is enough to charge phones, new standard Qi will be able to provide not only charging smartphones, but also, for example, tablets requiring more power.

Thanks to the Wireless Power Consortium, the wireless charger ecosystem is growing at a very fast pace. So, we have signed agreements with Virgin Atlantic and The Coffee Bean & Tea Leaf, where soon all tables will be equipped with built-in chargers: the phone will be charged just lying on the table while you are drinking your coffee. In Russia, we are also negotiating cooperation with various businessesto introduce the same tables with wireless chargers in their establishments as soon as possible.

Besides the main charger -

Idea wireless transmission energy appeared in the 19th century, and for the first time it was demonstrated by the Serbian genius Nikola Tesla in 1893 at the World Columbus Exhibition in Chicago. The seemingly miraculous technology has now become firmly established and is found everywhere, from funny but useless levitating bulbs to really convenient things like wireless chargers for mobile devices.

The technology of transferring energy to a smartphone battery without using a connector and cable appeared a long time ago, back in 2008, that is, just a year after iPhone presentations and the emergence of the smartphone market as it stands today. Device and component manufacturers have formed the Wireless Power Consortium to unite different manufacturers to create universal wireless charging technology. Thanks to this cooperation, the Qi technology appeared - it is read "Qi" (less often "Chi") and means "energy" or "life force" in Chinese philosophy. Thanks to the work of the Consortium, the requirements and principles of operation of devices and charging stations supporting the Qi standard were determined, as a result of which users today can use induction mats without regard to the smartphone brand and not change accessories after purchasing a new device.

It cannot be said that after the approval of the Qi technology standard and the start of its use, all other companies curtailed development. Research is constantly being carried out to ensure a significantly faster charging speed or an increase in the distance between the mat and the device - but none of this is ready for mass production and in the absence of worthy revolutionary ideas, more and more smartphone manufacturers are beginning to implement support for the Qi standard. Even Apple and Sony “gave up” by adding support for wireless charging to the 2017-2018 smartphone lineup, and the list of outsiders so far includes only inexpensive Chinese brands that are trying to save on components or do not want to change the streamlined production of the same type of aluminum cases. However, the situation may soon change, for example, according to rumors, the flagship Xiaomi Mi7 will support charging according to the Qi standard.

The accessories market is also constantly evolving. Wireless stations for public spaces begin to be shipped, induction pads are found in cars or sold as optional accessories for cars, and many solutions for home use are emerging. And most importantly, most often the prices for wireless chargers are not so high as to deny themselves the convenience of using them. Branded accessories from manufacturers can be sold at a very high cost (4-7 thousand rubles), but there are always alternatives from third-party manufacturers that are not inferior in design, quality and technology. For example, now we are testing the Expert NBE-WC-12-01 model (1890 rubles) with support for an extended version of the Qi Fast Charge standard and a current strength of 1.2A.

This Nobby model is a compact round platform. The manufacturer uses high-quality and pleasant-to-touch black plastic, there is also a luminous ring that changes color at the moment the smartphone starts charging. The accessory does not take up much space on the table, and most importantly, it has a classic flat surface. This is true for smartphones like Sony Xperia The XZ2 has a curved back that can roll off some charging stations but rests on Nobby accessories. There is no risk of putting the smartphone in a wrong way and then finding it next to the rug uncharged.

We tested a Nobby device with an iPhone X, Samsung Galaxy S9 and Sony Xperia XZ2 - in all cases it was very convenient, because you do not need to look for a wire, connect and disconnect it, but you can put your smartphone on the platform at any time. In terms of speed, the Expert NBE-WC-12-01 works as advertised and really quickly charges the smartphone.

As for the principle of operation of wireless chargers, everything is quite simple with this. Base station consists of an induction coil that creates an electromagnetic field when an alternating current is supplied. The device contains a similar coil capable of trapping this field, converting the received energy into direct current - and transferring it to the battery for recharging. However, this explanation is for the average consumer, techies know that in reality the system is more complex and it also uses current converters, rectifiers, controllers, voltage regulators and other circuit components. But is it so important to know ordinary consumer? Other questions seem to be much more interesting: health effects, safety of use and restrictions.

Despite the appearance of an additional source of radiation in the house, there is no need to worry about this. Qi chargers use non-ionizing frequencies that are guaranteed to have no harmful effects on health. Moreover, both humans and small pets. Over the ten years of the Consortium's work, many studies have been carried out, and all of them have confirmed the possibility of using charging stations without restrictions. As for safety, there is also complete order: charging is possible only with Qi-compatible devices, there is a temperature control system in case of sudden heating. Even if a foreign object gets on the charging mat, there will be no problem.

As for the restrictions, the only thing that manufacturers cannot yet "beat" is metal cases... From the first devices like the Lumia 920 to the iPhone X, smartphones have to experiment with materials. Previously, it was plastic, which was used even in the premium segment, but now it has been replaced by more spectacular glass. Perhaps this is why iPhone owners have been deprived of the ability to charge smartphones on rugs for so long. During the Quartet era, Qi was not yet so popular, and after that the company relied on metal for a long time. Now, partly because of the desire of manufacturers to implement the wireless charging function and partly because of the eye-catching design, the most popular material for rear panels the flagships were glass. All current iPhone lineup, Samsung Galaxy flagships, latest sony Xperia XZ2 and XZ2 Compact, LG V30 ThinQ and Nokia 8 Sirocco - these and other top-end devices support Qi technology.

As a result, we cannot think of a reason to stop using Qi chargers if the smartphone supports this technology. A wireless mat is very convenient because you can just put the device on it, and not look for wires and a connector. The accessories are inexpensive, harmless and safe. We have already mentioned the Nobby brand and decided to talk about how we use it in the editorial office. The Expert model was chosen as the best option for office use - at work most often we only charge one device and a higher speed is very important to us. For example, if you need to urgently get together for a meeting. However, in lineup Nobby accessories have other wireless chargers. For example, the Nobby Practic NBP-WC-10-01 model has an output current of 1A (that is, it charges slower), but it is equipped with two uSB ports for wired connection of devices. This solution is well suited for home use, since it allows you to take up only one outlet, and charge your smartphone wirelessly and other devices such as smart watches or headphones.

Wireless chargers seem like a panacea for those mobile device users who hate to mess with wires. However, they should not rush to buy wireless storage devices - first you need to make sure that the gadgets they possess are equipped with the technology Qi and can interact with charges such as Wireless... In this collection, we will tell you about modern smartphones that support wireless charging - perhaps our recommendations will help you choose a gadget that will not make you constantly search for an outlet.

According to the characteristics, this Chinese smartphone supporting wireless charging is also at its best. It received a high-performance Snapdragon 801 chip with 4 cores at 2500 MHz, as well as an Adreno 330 video accelerator. In addition, Mi Note has 3 GB of RAM in its arsenal, thanks to which the mobile phone works incredibly fast. The sensor works smoothly and supports up to 10 touches.

Samsung Galaxy S7

Today, many people want to buy a phone with wireless charging and two SIM cards. The largest manufacturer Samsung gives its fans this opportunity. The Galaxy S7 is the best smartphone to date, no matter how you look at it. Its superiority begins, of course, with the design: a thin aluminum body, tempered glass, a function button. As for the display, the 5.1-inch AMOLED screen with 2560 × 1440 resolution offers an incredibly rich and clear picture. The battery is also okay: lithium polymer battery at 3000 mAh it can work up to one and a half days, thanks to a well-optimized OS.

Mobile phone with parameters better Galaxy S7 cannot be found. The top 8-core Exynos 8890 processor with a frequency of up to 2300 MHz with the Mali-T880 MP12 video chip in combination with 4 GB of RAM is fantastic performance and incredible smartphone speed, which is objectively hard to find equal. The only thing that, in our opinion, was not taken into account by the manufacturers is the installation of a microUSB connector, which, in our opinion, should be replaced with a more modern Type-C.

Conclusion

Our rating of the best smartphones with wireless charging in 2017 gives only a brief idea of \u200b\u200bmodern devices with such technology. Every year there are more and more such devices, the choice is wider and wider. Options are offered for every taste, so only an electronics lover can choose which smartphone to buy, taking into account his own requirements for the gadget and, of course, the budget. It is also worth noting that this technology is only developing and has not yet been fully developed, so it will take much longer to charge your gadget than if you were using conventional wired charging.

Today, a person without a smartphone is a person cut off from life. It is hard to imagine that a few years ago a mobile phone was used only for communication. Now this little assistant gives us access to the Internet and a variety of applications, and wakes us up in the morning. The list of benefits provided by a smartphone is endless. It is not surprising that a large number of gadgets have been invented for modern phones. One of them is a wireless charger, which we would like to talk about in more detail.

How can I tell if my phone supports wireless charging?

From the name it is clear that this is a gadget that allows you to charge your smartphone without using wires. It is a small stand connected to the network. Inside is an induction coil that creates a small magnetic field around itself. If there is a smartphone within the radius of this field, then it will receive electricity in the literal sense of the word through the air. But there is one caveat - an induction coil must also be built into the smartphone. It will serve as a kind of energy receiver from the charger.

The goal of creating this device was to rid modern smartphones of the charger connectors, and also to allow all devices in the house to be charged from one platform. The idea was a success, but why then do we not see this technology in every home and do not use it ourselves? The answer is simple - despite all the advantages, this miracle device also has disadvantages.

Pros and cons of a wireless charger

Wireless charging has enough pros, but they all have their cornerstone.

Lack of wires

Without a doubt, this is a big plus. Wires have always been a weak point in charging. With frequent bends, the wire was easily damaged and tangled. Frequent recharging would loosen up the USB port on the phone, and sooner or later, repairs were required. But there is also a downside to the coin. The rejection of wires reduced the efficiency (efficiency) from 90% to 60–75%. Simply put, when using wireless charging, your smartphone will charge approximately 2-3 times longer.

Range of use

It would seem that there are no wires - there are no restrictions, and you can charge the phone simply while in the apartment. But no - the range of use of the wireless charger is very modest (3-5 cm) and the phone will have to be placed on the stand. Another significant drawback will be the inability to use the smartphone while charging.

Price

The cost of the charger is quite variable, but it will always be more expensive than the usual charging.

Standards

I would like to talk about the standards thanks to which the use of technology for the transmission of electricity by air has become possible.

Qi ("Qi", after the term of Eastern philosophy) was developed by the WPC (Wireless Power Consortium - Consortium of wireless electromagnetic energy). It is the most widespread and supported by such giants of the mobile industry as Asus, Motorola, HTC, Huawei, LG, Nokia, Samsung, Blackberry, Sony and others. You can find out more about the standard and the list of supported devices on their official website.

The PMA standard also uses the principle of electromagnetic induction, but cannot boast as many manufacturers that support their technology as Qi. It was developed by Powermat, which is currently trying to fight unhealthy competition from Qi.

This standard uses Rezence technology, which is fundamentally different from PMA and Qi. The strange thing is that the most unpopular standard has many advantages over its competitors. The pluses include:

the ability to charge through interference (if you put the book between the smartphone and the charger, nothing will change);
one platform can power multiple devices;
work in close proximity to metal objects, etc.

For a complete list of smartphones that can use wireless charging right out of the box, visit the official website https://www.wirelesspowerconsortium.com. I would like to note that most of the manufacturers have made sure that their product supports the use of this technology.

What if your smartphone is not on the list of supported devices, but you need to use wireless charging? If you have such a question, then most likely you are a happy user of Apple products. The iPhone is not yet capable of receiving electromagnetic signals. However, there is an alternative - the purchase of an auxiliary accessory that will do this for your phone. It fits under a standard case and does not cause any discomfort.

Is wireless charging harmful to health

Like any new technologyThe wireless charger raises many questions. One of the most acute is whether it is harmful to health. Let's dispel this far-fetched myth right away. It will do you no more harm than an electronic razor using the same technology. The developers of the WPC standard assert the same.

We hope our article was useful and helped to understand the compatibility of your smartphone and wireless charger.
