It may seem strange, but until just 10 years ago, the idea of ​​a device for wireless charging of mobile phones and other electronic gadgets did not have a very positive technical and economic perspective, and investors were skeptical about entering this field.
It is interesting to know that even the people of Cupertino, who in recent years are considered to be the leaders of innovation in the world of mobile phones, were not among the main supporters of wireless charging technology until last year, and recently and for the latest model of their iPhones, they support This standard has been changed and wireless charging has been considered for iPhone 8 and iPhone X !
Nevertheless, experience has proven that nothing can stop human curiosity and stop innovation and creativity, and in the end, it is always the technology lovers who impose their dream on the world in the form of an efficient and innovative product.Â
What is the Qi wireless charging standard?
Qi is an international standard method for transmitting electricity energy without the use of wires and by electromagnetic induction, which was introduced to the world by the ” Wireless Electric Power Consortium ” and is free for all manufacturers to use.

Oceanic Inspiration
This technology is a truly innovative and revolutionary method that works based on a scientific concept called the induction coupling phenomenon. In this process, a main station or charger transfers electric power in the form of non-radiative electromagnetic waves to the receiving device that needs to be charged. These waves are received by the coils in the receiving device, which are usually embedded in the back part of the device, and are converted into the electricity needed to charge the device’s battery.
In addition to the main process of electromagnetic induction in Qi-based chargers, what distinguishes this standard from other methods is its combination with the ability to amplify electromagnetic waves, because, in the absence of this ability, the charger device and the receiving device must be at a very small distance from each other. should be placed and their surface should be stuck together. However, the intensification process in Qi enables the process of wireless charging without a connection, without significant waste of energy, in short distances of a few centimeters.

Although the foundation of this technology has remained the same over the years, overall, the Qi standard has become smarter. Today, Qi-based chargers understand the presence of a compatible device around them and know when to start or stop the charging process. In fact, devices compatible with the Qi standard can interact with each other!
The strengths and weaknesses of wireless charging
Now that we know the Qi standard and how it works, we can better examine its advantages and disadvantages.
Strengths
Avoid crowding the environment
- When you use a wireless charger, only one line of wire is needed to be connected to the power, and therefore, your desk or room will be less crowded. The story becomes more interesting when you use power banks based on the Qi standard, in which case you won’t even need a single wire! Therefore, if the orderliness of the work environment is very important to you, wireless chargers are the right choice.
security
- Wireless chargers are constantly exploring their surroundings and only connect to virtual devices that feel close to them perform charging operations for authorized devices and disconnect when the charging operation is complete. They put themselves in silent mode. In addition, due to not using the wire and socket structure in this charging system, the possibility of a short circuit that may lead to fire or damage to the device or even human electrocution is eliminated.
Being inclusive
- Since the Qi standard is an open and flexible standard, it can be used for all devices based on Android and iOS, and chargers based on it can be used to charge a wide range of devices from different brands. Of course, this is if the manufacturing companies themselves are inclined to this issue and include the necessary hardware facilities in their products.
Variety of models
- Several manufacturers around the world are offering products based on the Qi standard to the market, and the variety of these products is also very good. For example, instead of buying several small charging pads for your various devices, you can get a wide and large charging pad to charge several devices at the same time. The variety of colors, materials, shapes, etc. has its place!
Wireless Charger Pad Stand Speaker TF Card RGB Night Light Lamp Alarm Clock Fast Charging Station Dock for iPhone Samsung Xiaomi Original price: EUR 24.14 Now price: EUR 9.92
Joyroom Magnetic Car Phone Holder 15W Qi Wireless Car Charger For iPhone 14 13 12 Series Fast Air Vent Charging Phone Holder Original price: EUR 30.09 Now price: EUR 10.81
Being incluThe speed of market growthsive
- With the widespread use of wireless chargers, now even in public environments such as markets or vehicles such as intercity trains, we see the installation of Qi-based wireless charging equipment, and the market for products based on this standard is also growing at a surprising speed. Therefore, in the coming years, products related to this field will certainly be available in abundance and at reasonable prices, anywhere in the world, and you will not have a problem of running out of charge on your mobile phone while traveling or when you forget your charger.
weak points
-  Not very cheap price:  wireless chargers are not offered as the main charger in the box of mobile phones and other gadgets, and their price is considered so cheap compared to the usual wired chargers. For example, the original Samsung Galaxy Note 8 charger, which is of the USB Type C type, has a price of about 70 thousand Tomans, while the original Samsung wireless charger pad should cost about 250 thousand Tomans. Anyway, if the advantages of these chargers are important to you, probably the price difference of these tools with the original charger in the box will not affect your choice.
- . Not so convenient to use: While using wireless charging seems to be much more convenient than using wired chargers, the reality is something else. Today’s wireless charging technology is not yet advanced enough that long-range wireless chargers (for example, the version that can charge your cell phone from a distance of 3 meters) can be commercialized and offered to consumers at an affordable price. For this reason, you always have to place your mobile device in the vicinity of the charger that is also connected to the outlet, and for this reason, you will still face limitations and you will not have complete freedom of action. Although the manufacturers of wireless chargers add to the features of these devices every day and include interesting features such as luxury designs, determining the location of the mobile phone, display of the charge percentage, etc., but still far from providing the real experience of a long- range wireless charger . we should wait.
