What we all expect in a few years, it is difficult to predict, since technological progress is developing incredibly fast, walking not by leaps and bounds, and rushing at an incredible speed. In the minds of engineers, fantastic ideas are born that after a short period of time come true. Charging phones, excluding any wires, is now quite realistic. However, many users still can not figure out how the wireless charger for the phone, considering that such manipulations are in the same row with the fantastic acts.
Now you can charge your smartphone using a wireless device.
If you are tired of unraveling the cords every time you need to charge your smartphone, then it is really useful for you to consider an alternative kind of energy transfer. To consciously approach this process, eliminating any doubts, it is useful to understand what the principle of the direct operation of wireless charging is.
The operation of alternative recharging
Hearing for the first time that there is a wireless charging for the phone, many smartphone owners begin to fantasize themselves, convincing themselves that the distribution of energy will occur at any distance. Of course, this is an incredible fallacy. In no case can not compare the wireless charger for the phone with Wi-Fi.
Trying to figure out how wireless charging works, it is useful to familiarize yourself with additional information, from which it will become clear that charging, excluding the use of wires, is a kind of magnetic induction charging.
If you decide to acquire wireless charging, begin to actively use it, it will not hurt you to understand the principle of wireless charging for your phone.
Wireless power transmission technology
Scientists are actively seeking innovative technologies that expand the capabilities of users who are focused on the constant use of modern gadgets. In particular, modern researchers are ready to say that electricity can be distributed successfully using a laser, sound waves, and many other physical phenomena. However, most of these technologies are still under active development.
Among them there is one technology that is already actively used at the moment and is used with great success for commercial purposes. It is the transmission of electricity using electromagnetic induction that formed the basis of modern innovative developments that made it possible to practically implement the principle of wireless charging for a telephone.
In any technical field there are certain standards, which are important to consider when inventing or improving devices aimed at maintaining the performance of modern gadgets.
The Wireless Power Consortium developed a standard seven years ago that focuses on the transmission of electricity wirelessly. This standard is called the Chinese word Qi.
Most manufacturers of smartphones not only actively welcome such a unique standard, focused on charging the gadget without using wires, but also use the Qi standard in the manufacture of their products.
For this reason, being at bus terminals, railway stations, airports of economically developed countries of the world, a person gets the opportunity to charge his smartphone without burdening himself with the search for free sockets. In such crowded places, special charging stations are installed, allowing all those in need to use wireless charging.
How wireless charging works
If you figure out how wireless charging works for your phone, it becomes clear that they are equipped with special induction coils to ensure contact between the receiving and radiating devices. Of course, no matter how you try to recharge your old-fashioned mobile phone, being in close proximity to such a distributing station, you will fail, because the gadget was not directly equipped by the manufacturer with such coils.
The principle of the wireless phone charging is the formation of a magnetic field. In particular, after connecting the charging station to the mains, the induction coils inside it create a magnetic field. If a device that supports the Qi standard enters this magnetic field, it begins to actively absorb electromagnetic waves and then convert them into energy using the built-in induction coil, ensuring a confident charging process for the battery.
It is important to understand how to use wireless charging. Suppose that you can charge your smartphone, while at a decent distance from the charging station, you can not. It is recommended to place the discharged gadget at a distance not exceeding five centimeters.
Even if you put the smartphone directly on the wireless charger itself, then the efficiency of such a charge will be about 80%. Of course, the one who is used to getting the maximum of useful manipulations, will easily notice that charging the phone with a wire still has a higher efficiency.
If you conduct a practical experiment and calculate how different the charging time is when using traditional and alternative charging, it becomes clear that in order to fully charge the battery when using wireless technologies, you will have to rely on additional time of about one hour.
Quality characteristics of the device
If you have studied the question of how to use wireless charging for your phone, it doesn’t prevent you from becoming familiar with its advantages and disadvantages, its impact on human health. Armed with this knowledge, it will be much easier to make the final decision.
Advantages and disadvantages
The main advantage is that you will not have to connect the wires to the smartphone itself, which are often lost, twisted, fall into the hands of pets, and therefore are seriously damaged.
Unfortunately, completely forget about the wires still does not work. Wires are excluded only with respect to the smartphone, but the charger itself is still connected to the outlet with wires and an electrical plug.
Another drawback that can cause frustration for the acquirer is the sufficient duration of charging the mobile device.
If you decide to purchase such an innovative device, you will also have to tune in to the fact that the cost of wireless charging is several times higher than the wired analog.
Health effects
Each working mechanism emits electromagnetic waves. A modern person who cares about his state of health is concerned with the question of how harmful such radiation is, whether the risk of occurrence of pathological changes in the body is eliminated when being in close proximity with a wireless charger in operation.
The anxiety is quite understandable, since from time to time articles appear in the mass media that emphasize the reader’s attention to the dangers that modern technical means provoke. However, experts claim that this is nothing more than myths, because the danger to human health is completely excluded.
IMPORTANT. Electromagnetic waves involved in the wireless charging process are accompanied by a low frequency, so any negative effect on humans is excluded.The same waves pass through a person every day, but technical progress has nothing to do with this. Exactly such waves in strength and frequency radiates from the sun.
In addition, it is important to understand that it is unlikely that anyone will constantly stand near the charger throughout the entire cycle of its operation. For this reason, engineers, doctors and other specialists confidently refute the myth about the harm of memory to human health.
Varieties of Wireless Storage
After reviewing the advantages and disadvantages of chargers, excluding the use of wires, many users have an active desire, despite the high cost, still become its owner.
Currently, manufacturers are ready to offer several options for such devices, so before making a purchase, it is useful to understand their distinctive features in order to understand which model can be rightly considered the best.
Popular Charges
The Samsung company, accustomed to surprising consumers with interesting smartphones, did not ignore the issue of creating a wireless charger. The result of the company's work on such a technical problem is the Samsung Wireless Charging Pad.
Many users welcome it, because it allows you to charge your smartphone, which can be in any position relative to the top surface of the charge itself.
Samsung Wireless Charging Pad provides charging for smartphones that support not only the WPC standard, but AW4P and PMA.
Highly popular is accompanied by another device - PowerBot. It is welcomed by the consumer because:
- itself can be connected not only to the mains, but also to a laptop;
- has an acceptable cost;
- accompanied by a high level of reliability;
