 How does wireless charging technology work?


 Wireless charging means charging without connecting wires. It has changed the method of powering devices. Whether at home or in the car, you can charge various gadgets without cables. This feature is available in flagship phones and smartwatches that have recently come into the market. Today we are talking about how wireless charging works.






How does wireless charging work?


It's been more than a decade since wireless charging came into daily use. But since most of the gadgets in the market have provided this feature, wireless charging has started to be seen everywhere. With the help of this technology, it is enough to charge the device by placing it on the charging sand or pad. No need to search for a physical cable and connect it to the phone.


Copper coil is used in this technique. A transmitting coil (a coil that can transmit electricity) is placed on the charging sand or pad, while a coil that can receive the charge is placed on the device.


When the charging pad or sand is connected to a power source, an electromagnetic field is generated through the transmitting field. Generally speaking, when you plug in the charging sand or pad, there is a kind of invisible force field created.


That area is like a bridge. Which receives energy from the main source of electricity and creates an electromagnetic field around it. The electromagnetic field generates an electric current in the coils of your device. This charges the battery in the phone.


Depending on the device, the coils placed inside it may be different. In the case of smartphones, the coil is placed in the middle part of the back. A coil is placed behind the watch face in a smartwatch. The coil is placed on the bottom of the earbud.




Types of wireless charging technology


Generally, two types of wireless charging technology are in use, inductive (inductive) and resonant (resonant). For inductive charging, the charger and the device need to touch. Most wireless chargers are using this technology. So you have to keep the device on a charging pad or sand for this.


Resonant charging is another technique of wireless charging, where the device to be charged and the charger do not need to be connected or touched. But it works only at a very short distance. Putting the charger in one corner of the room and not connecting the phone to the other corner does not magically charge it. It can only work at a distance of a few centimeters.




Wireless charging standard


The devices we use or see, from earbuds to smartphones, support wireless charging. However, not all devices use the same wireless charging standard. The standard of the charger varies depending on the device you use and the brand. The most commonly used wireless charging standards are discussed here.




1) Qi wireless charging


Qi (also pronounced Chi) wireless charging was developed by the Wireless Power Consortium (WPC). Nowadays, this charging standard is the most widely used. Especially Apple, Samsung, Belkin and other brands have been using this standard.


The new generation of this charging standard is called KuiTu. It was released in 2024. Electricity is also kept in this charging system. This makes the charger more efficient. QI and QI Two are powered by inductive charging. That is, the device of this standard needs sand or a charging pad to charge it.


These chargers support 5 to 15 watts. Today, Honor's Magic Six Pro is said to support wireless charging up to 66 watts. Recently, the field of wireless charging is also developing rapidly. Fast charging is also being worked on.


Apple has introduced a premium version of Qi charging called MagSafe. Which works like QI2. Apple initially provided the feature on Macbook laptops and later started providing it on iPhone as well. The iPhone 8 is the first iPhone to feature wireless charging. The iPhone 12 is the first iPhone to feature MagSafe charging.




2) PMA (Powermat) wireless charging


PMA is another standard for wireless charging prepared by the Power Matters Alliance. This is also similar to the QI standard. Where inductive charging technology is used. But the communication protocol used in it is different. Devices that support QI charging cannot be charged on Powermat. Such a charging system is placed in public charging stations.




3) AirFuel wireless charging


In 2015, the PMA merged with the Alliance for Wireless Power (A4WP) to become the AirFuel Alliance standard. These two companies had prepared a new standard charging system by combining radio frequency and electromagnetic resonant charging technology. Due to this, even when the user is using the phone, the phone can be charged through wireless charging.




Advantages and disadvantages of wireless charging


Wireless charging 

Although it has been in use for years, it has some advantages and disadvantages compared to wired charging systems. Which is discussed below.




easy


The wireless charging system is much easier than the wired charger. You don't have to bother looking for a separate cable for this. All you have to do is place the device on the wireless charging stand. By placing it on the sand or charging pad, the device starts charging automatically.


Different devices can be charged on the same wireless charging sand or pad. For example, devices such as phones, smartwatches, earbuds, etc. can be charged simultaneously in the same sand. It helps to charge the device in an orderly manner.




durable


In wireless charging, there is no need to insert and remove cables like wired charging. Even if you place the device in the sand, it starts charging. This makes your cable and device's charging port more durable. You can use a wired charger if there is no wireless charging feature. As there are both facilities, you can use whichever is suitable according to your needs.




But the charging speed is low


There is no doubt that wireless charging is very easy to use. However, charging through this takes more time than a wired charger. That is, the speed of wireless charging is reduced. The more coils on the device and the alignment of the sand and the phone during charging, the faster the charge. However, it is not as fast as a wired charger.




ease


Most of the flagship devices available in the market these days support wireless charging. In entry level devices, traditional chargers are required. If you have any device that supports wireless charging then this is easy. Because there is no need to carry different chargers for different devices. However, there are some that support wireless charging and some that don't.




What to consider when buying a wireless charger?


If you are buying a wireless charger, keep the points mentioned below in mind.


1) Charging speed


Wireless chargers have different charging capacities. The higher the wattage of the wireless charger used, the faster your device will charge. So it is best that you buy the highest wattage wireless charger that is compatible with your device.


2) Purchase a wireless charger that is compatible with all devices


You may have various devices that support wireless charging. So, while buying a charger, make sure to buy a charger that is suitable for all devices.


3) Design


There are some technical specifications. Apart from that, the design is also an important aspect. Make sure that the design of the charger you buy is suitable for you.
