Wireless chargers

Any smartphone, like other mobile devices, must be periodically recharged in order for them to work. Mains chargers, to which devices are connected via cords, are not always convenient (the wires break, get tangled, clutter up the space, etc.), so manufacturers offer other options.

One of the newest inventions is the wireless phone charger. It looks stylish, takes up little space and is equipped with additional functions, such as a signal indicating the charge level. This device is worthy of closer study.

What is wireless phone charging and how does it work?

A wireless charger for smartphones is a compact panel that transfers energy to a gadget placed on its surface. There are two types of such devices - wired and wireless portable charger.

In the first case, it is powered from the mains, and in the second, from an internal battery, which can be charged for future use. You can use a portable wireless charger outdoors, while traveling, in a car, in case of a power outage, and in other situations when it is not possible to connect to the network.

Wireless charging works on the principle of magnetic induction, which became its basis. The point is that electromagnetic radiation can transmit current over a short distance without the help of wires. To do this, there must be two coils - conducting and receiving.

The wireless charger for the phone acts as a conductor, and there is a receiver inside the gadget. When devices are close to each other, the process of transferring electricity occurs:

• alternating current enters the coil inside the charger, forming an electromagnetic field;
• the receiver coil in the smartphone picks it up;
• current passes through the rectifier, turning from alternating to direct;

As a result, the gadget’s battery receives the charge it needs.

Types of Wireless Chargers

Wireless chargers differ from each other in many characteristics, including shape and size. They should be taken into account when choosing products, since the ease of their use in different circumstances depends on this.

There are the following types of chargers from the manufacturer:

1. Puck. A round and flat wireless charger, which should lie on the surface of the table (or any other), and the gadget is placed on it;
2. A rug. They are less rigid than “washers” and take up more space (they can accommodate several devices); they are also installed in a horizontal position;
3. Stand. The gadget can be placed in a vertical position (with an adjustable tilt), which is convenient if you need to look at something in it while charging.

If you are planning to buy a wireless charger, you should decide in advance how many devices should be recharged on it at the same time, since there are models that allow you to place smart watches and headphones on one panel in addition to your phone.

Parameters of wireless chargers for smartphones

When choosing a wireless charger for your phone, you need to pay attention to the following parameters:

1. Speed of work. The speed at which the smartphone will charge will depend on the power of the device. It can be from 5 to 15 W. Energy-intensive gadgets require powerful charges to make the procedure quick and comfortable;
2. Safety. Its charger must also provide protection for devices, in particular, from power surges, overheating, overcharging, and short circuits;
3. Charging standard. There are several of them: Qi, Samsung, PMA, Airfuel. Qi is considered the most popular - it is supported by many modern phones, including the iPhone.

It’s also worth considering the device’s ability to charge the gadget through the case if you use it and don’t want to constantly take it off.

Benefits of a wireless charger

Whatever shape or size your wireless charger is, it will definitely have the following advantages:

• ease of use - you just need to “attach” the gadget to the charging surface;
• versatility – you can charge different types of mobile devices, not just smartphones;
• minimum wires - only one is needed (for the docking station);
• durability – Since there are no cords to break or break frequently, your wireless smartphone charger will last longer.

If you take an accessory with a transparent coating, then the glass should be tempered - it is stronger.

Is wireless charging dangerous for a smartphone?

Many users decide to buy a wireless charger because it is a convenient, stylish and modern device that can be used in different conditions. But can it be somehow dangerous for a gadget or a person?
Since the technology is still considered new, there are speculations surrounding it that scare people. Let's dispel the main ones:

1. Do electromagnetic waves harm human health during operation of the device? No. This type of radiation is not ionizing, therefore it is safe for the body;
2. Does contactless charging reduce battery capacity and accelerate its wear and tear? No. The reasons for shortening the battery life are different: frequent recharging, using the phone while charging, etc.

People have already appreciated the benefits of this technology, and over time it will become even more popular, therefore, even if the price of such devices seems high now, in the future they will be inexpensive as demand grows.
