Work principles
Modern devices are equipped with various cables and chargers that are not always convenient to use. Especially when traveling or on a business trip, outdoors, etc.
Today, there are new developments on the technology market that allow charging mobile devices without a wire. The charging system is built into a public place, household items, airport lounges, mobile devices, or gadget cases. Also, popular iPhones and Android models are equipped with a new function.
Does it charge without contact? at a distance of 5 cm between the charger and the gadget, taking into account the thickness of its body. Power is supplied by a magnetic field (electromagnetic induction) that a charger creates around itself. Some models of gadgets are made of glass, as it tends to pass energy through the phone. This allows it to be charged without a cord.
There are models of chargers that allow you to charge phones by placing them with the back panel on a docking station (special surface). In this case, recharging takes place in automatic mode.
Advantages and disadvantages of the contactless charging system
The new wireless power system has its pros and cons. The biggest advantage of modern inventions is time saving, which is very important in modern society.
Advantages:
- modern charging method simplifies recharging during the day;
- stable location of the power supply system, connected to the mains;
- you can recharge your phone at a convenient time;
- makes life comfortable;
- there is no cord;
- you can charge several gadgets from one charging station;
- conveniently recharge mobile devices in public places (dinner at a restaurant), bedroom, office or car;
- makes it comfortable to watch TV shows and movies, video calls while charging by placing the phone on a vertical stand;
- it is convenient to place it on an office or home desk when the gadget is not in use (a guarantee of normal phone charging);
- the detachable socket for wire recharging is kept in working condition.
Disadvantages:
- the charging process is not completely wireless (you need a charging station);
- it takes more time to recharge;
- charging systems have a slow task execution speed;
- use of different standards of combinations for powering gadgets;
- accessories for power supply must be periodically charged from the mains (or you need constant access to the mains);
- bulkiness of the system power supply;
- the charger requires a perfectly flat horizontal surface;
- the charging system consumes additional electricity;
- high price of gadgets with Qi technology.
Wireless charging standards
Qi technology, which allows you to charge gadgets from a distance without a wire, was developed in 2009. The specialists of the Consortium of Wireless Electromagnetic Energy have developed a standard for transmitting energy power at a distance of up to four centimeters. Its name is associated with Eastern philosophy and is pronounced "Qi" which means "energy flow".
This is the most widely used wireless charging standard. It is supported by popular models of smartphones and tablets (Asus, Motorola, HTS, Huawei, LG, Sony and Samsung). With its help, you can carry out more accelerated charging. In this case, the maximum power of the chargers is 15 W. You can charge gadgets from 0 to 59% in 30 minutes.
On the principle of electromagnetic induction, another standard is used - PMA, introduced since 2012 by the manufacturer Powermat. The company uses a 2-piece charger with the main focus on the transmitter. This recharging system is being implemented in US establishments. Differs from Qi technology in operating frequency (for PMA 276 - 236 KHz).
A less popular charging system is the A4WP standard, which uses Rezence technology. It makes it possible to recharge gadgets at a distance of more than 4 cm. At the same time, various household items are not an obstacle. One station can charge several devices at once. It can be used to create a “smart zone” needed for charging around the power supply.
This system uses the principle of magnetic resonance, which makes it possible to use the standard without embedding it into the gadget case. The device has a power of 50 watts (suitable for a laptop). The standard is supported by such popular manufacturers as Qualcomm, LG, Intel, HTC, etc.
Advice! Handle the power cord with care when charging frequently. Near the casing of the working surface of the device, the wires may be bent, which can lead to damage to the device for charging. After breaks, the wire cannot be restored. The charging will need to be thrown out.
Varieties of wireless chargers
There are different charging systems:
- network device - works from the network through a cable in standard mode;
- docking stations for cars - connected to a car cigarette lighter with a charging plug;
- wireless charging system.
There are two types of wireless charging, depending on the location of the mobile device:
- horizontal;
- vertical.
There is a division in the high-speed mode of charging the power supply system:
- high speed;
- standard mode.
By placing the system power supply in a convenient place, you can recharge the phone in your free time. There is always a guarantee that the gadget is ready for use. It is very convenient. Especially if you urgently need to leave, you always know that he will not let you down at the right time.
Choosing a charger: selection criteria
Currently, the sale of wireless devices is only gaining momentum. And it is quite difficult to buy a high-quality system unit. These are mainly expensive device options. But there is an alternative: a charging system from Skywy has been developed that meets all modern quality standards, but at a lower price.
When choosing a gadget with a built-in wireless power system, you must follow some guidelines:
- you should choose a smartphone with the Qi standard, which must be registered in the characteristics of the mobile device (the charger must have the inscription "Qi certified");
- check the list of phone models that support individual chargers (take into account the ability of the built-in system of the gadget to consume the energy given by the power supply);
- study the characteristics of gadgets;
- "Budget option": a charger with a power of 5 watts (with the phone's ability to consume more energy, such a charge will take more time, but will save a certain amount of money);
- when buying a charger with a power of 10 watts, you need to purchase a power adapter with increased power;
- the principle of "value for money" should work;
- availability of the "fast charge" function.
A charging system with a larger area of the stand can charge allows you to charge more devices.
Induction charging safety
According to WPC manufacturers, wireless charging does not have an ionizing effect on the human body. That is, there is no radioactive radiation when charging gadgets, since individual chargers do not create a field of increased power. Therefore, it is safe and does not threaten the lives of owners of mobile phones.
Still, powerful electromagnetic radiation can disrupt the body's work. Charging stations that allow you to recharge gadgets at a distance of 10 mm and more than meters deserve special attention. They must be treated with caution.

Errors when choosing devices for charging
Before buying a system for charging, first of all, you need to choose a model, decide on its quality, taking into account all the pros and cons, read consumer reviews, and determine the price. Sometimes you need to pay attention to inexpensive, "budget options" of the product. Inexpensive products are not inferior to the technical characteristics of fashionable branded models with high prices.
It is worth taking the device in special stores or on proven sites on the Internet. A cheap fake charger can get hot and, thus, harm the gadget that is on charge (overheating and swelling, which leads to an explosion). This is due to the fact that such products do not have "smart protection" against overheating, since unscrupulous manufacturers produce a product with poor quality wires, where there is no copper component in the transformer.
During the charging process, vibration occurs, due to which friction occurs between the turns. In this case, a poor-quality insulating layer becomes thinner, which leads to a short circuit inside the turns. Then the system overheats.
A poor-quality product can be identified by yourself by plugging it into the power grid without a telephone. If after a while the case warms up, then the charger is either faulty or of poor quality.
Modern wireless chargers are suitable for various phone models and meet quality standards, support the Android USB interface. This allows you to connect to your computer.
