Wireless Chargers

Wireless charger (CCD) can not be called a new invention, but many still have not had time to get to know him. It is designed to simplify the life of owners of electronic devices and eliminate the need to get confused in wires, trying to find the right one to plug into the connector.

Therefore, almost everyone who has used it for a long time no longer wants to return to their usual network adapter. And everyone who wants to buy such a device should figure out in advance what it is and how to use it correctly in order to avoid mistakes in the future.

What is wireless charging

Wireless charging refers to a special device that allows you to charge electronic gadgets. The electric charge is transferred without the use of a wired connection, which has become the main advantage of the invention.

This type of charging was created using a special standard called Qi. Translated, this word means "energy flow." Specialists developed it in 2009. Then it had to transfer energy at a distance of up to 4 cm. The existing developments, which did not receive successful development earlier, helped to create this standard.

Interesting! The first commercially available wireless type was launched by Powermat.

What does her device look like?

The BZU may look different. Most often, it is a small flat device on which you need to lay the gadget horizontally. Usually it has the shape of a rectangle or circle. There are also models in the form of a stand. This solution allows you to use the gadget even while charging, without bending to it at an unnatural angle.

Wireless charging is pretty simple. It includes only three main components: receiver, transmitter and electronic circuit. The first two are special coils through which current flows. And one of them is installed in the gadget whose battery you want to charge.

How Wireless Charging Works

The technology of charging without the use of wires is based on the effect of electromagnetic induction. First, the mains voltage is converted to alternating current, which passes to the coil, then a magnetic field appears.

If a receiver appears in the radius of the transmitter, they are paired. This happens as follows: when exposed to magnetic flux, the coil in the gadget begins to receive alternating current, then it becomes a constant voltage. The result is charging.

Most of these devices require an electrical connection. At the same time, during the transfer of magnetic flux, the gadget should be positioned so that the transmitter and receiver are as close to each other as possible to eliminate current loss. When the battery is fully charged, a sensor will work, which will turn off the formation of a magnetic field.

What devices can be charged

Most modern premium gadgets support wireless charging. This applies to all the latest Apple iPhone smartphones, as well as flagships and some mid-range models from Samsung, Huawei, Sony, HTC, Nokia, Motorola.The introduction of technology is also expected by other manufacturers of Android phones.

Attention! If the gadget does not support such charging technology, then you can purchase a special case or a separate module to help solve the problem.

Charging wirelessly is not only a mobile device. Many smart watches with a special module are designed for this. Also, without using a wire, the headset is charged, and with it the case inside which it is stored. Compatibility with the wireless charging method can be determined by the presence on the device of a special marking Qi.

How to use wireless charging

Using wireless charging is very simple. In most cases, you can figure out and connect everything yourself. But it is more correct to refer to the instructions in order to exclude any errors.

Charging Usage:

1. Connect the charger to an electric current source - to a wall outlet or computer.
2. Place the charging station on level ground.
3. Turn on charging by placing your gadget on the central part of the BZU.
4. Wait for the charge to end, remove the gadget.

After use, it is recommended that you turn off the device. Some models do not automatically stop the conversion of the magnetic field, which can result in a waste of energy.

Advantages and disadvantages of technology

Wireless chargers have advantages and disadvantages. It is they who often become the cause of the fierce desire to acquire such a thing or abandon such an idea forever.

Benefits:

• lack of need to stick a wire into the gadget;
• maintaining connector integrity and minimizing wire wear;
• most BZU are universal and suitable for all smartphones;
• the ability to choose from several types of charging.

The main disadvantage of such a charge is the cost. It is 3-5 times more expensive than a regular network adapter. Also conditionally present is another minus. If you use a station without the quick charge function, the gadget's battery will require more time until it is fully charged.

Is wireless charging harmful

There is still a myth that the use of BZU has a negative effect on human health. It is associated with the erroneous opinion that magnetic radiation is ionizing. This is not true.

The health effects of such charging are no worse than those of transmitting a signal over a mobile network or using Wi-Fi. If we consider the issue from a theoretical point of view, then only 120 watt devices could do harm. Now their power is limited to 5 watts.

Does not cause much harm to the BZU and the gadget itself. It can slightly reduce battery life, but by a small percentage. Much more battery wear comes from fast charging.

Varieties and types of memory

Wireless chargers come in many varieties. This allows the buyer to choose the most convenient model that meets all the requirements. Functional characteristics are practically unchanged.

Typically, the choice depends on the type of intended use of the device. Most often, only one specific variety is considered by the buyer.

Tabletop

It is a classic version used at home. It can be a horizontal station or an inclined stand. Some models combine both options, and the owner can switch them.

Such devices can be distributed throughout the house. This will allow you to charge the gadget where its owner is located. Such a solution will create more convenience and may become a necessity when creating a “smart home”.

Automotive

Charging your gadgets while traveling can be especially difficult. Wires are a big deal if you use your mobile as GPS. They cause a lot of inconvenience during everyday trips, when it becomes necessary to charge the device.

Touch holders with BZU solve all problems.They have reliable clips that make it easy to secure your gadget. While it is inside the device, its battery will be full.

Power bank

Portable BZU can be even more convenient. You can always carry them with you. For modern smartphones, this is extremely important, because many of them turn off before the owner’s working day ends.

Before use, the external memory must be charged from the network or gadget that allows this to be done using a wire. After that, it can be fully used.

With quick charge function

The presence of a quick charge function significantly speeds up the process of filling an empty battery. If it takes 2 hours with a conventional adapter, then new technologies will halve this time.

Before buying, it is worthwhile to clarify whether the fast charging of the necessary devices is possible. Some may not support it. Also, some gadgets can use this function exclusively when using the original memory.

Important! If the power adapter is too weak, fast charging will not work.

What to look for when choosing

Choosing a BZU is not as easy as it might seem at first glance. Before buying, you need to consider the compliance of the selected models with the main criteria. Some of them may not have much significance, but it is still worth considering them.

Criterias of choice:

• power, fast charging - it is advisable to purchase a device that has more than 5 watts of output;
• appearance, form - BZU should be as convenient as possible and combined with the home interior, if it is a desktop model;
• moisture protection - the presence of liquid protection can be very relevant, but most often this point is not so critical;
• the working area of ​​the station - if the coil is too small, then it will be difficult to place the gadget so that it is charging;
• the number of simultaneously connected gadgets - some models have more than one coil, which allows you to charge multiple devices at once.

It is also worth considering the thickness of your cover. It may not let the magnetic flux through, preventing it from filling the battery. This happens when the thickness of the cover exceeds 4 mm, or the presence of a metallic impurity in its composition.

Which manufacturers deserve special attention

It is recommended to purchase the original device, which is produced by the manufacturer, under whose brand other gadgets were purchased. But they are all universal. Therefore, if there is a desire, it is permissible to purchase any BZU. You just need to choose the right manufacturer.

Noteworthy are: Skyway, Mophie, Belkin, Moonfish, Rock, Momax, Nillkin, Samsung, Xiaomi and Hoco.

A quality BZU costs at least 2.5 thousand rubles. The cost factor also needs to be considered when buying. In the case of well-known brands, exceptions are possible.

Wireless charging is a very convenient thing that makes life easier for owners of modern gadgets. Using it is very simple. Therefore, it should be purchased by anyone who is tired of tangled wires and constant attempts to plug them into the desired connector. For a successful purchase, it is enough to correctly approach the choice, limiting yourself to the assortment of the most famous manufacturers.
