What is Wireless Charging, and How Does it Work?

Technology keeps on evolving day by day. Many new changes are brought in the technical field; as these changes come, we are always curious to know everything about it. Nowadays, everyone is talking about the new wireless charging feature that phones and smartwatches are coming up with. We all have inner hate for wires. Wires are prone to get torn off, tangled, and whatnot. That’s why the amazing technicians have brought wireless charging, and we feel so blessed, finally something to understand our feelings, the thing which we dreamt of for our phones.  

By now, you will be wondering what is wireless charging, and how does it work? Well, we’re going to answer these questions right away!  

What is wireless charging?

In simple terms, wireless charging refers to a charger with no wire, just a direct charger. It could be in the form of a stand or an electronic stick-on or a wireless device on which you have to keep your electronic device. The wireless charger is inbuilt with the phone’s mainboard and attached while its PCB Assembly is done. 

How does wireless charging work?

This is the most asked question by people, almost everybody knows what is wireless charging, but most people don’t know how it works?  

In Wireless charging, the concept that is used is electromagnetic induction. It means a transfer of energy occurs when the electronic device is kept near or on the wireless charger. The wireless charger consists of an induction coil, the induction coil transfers the energy onto the device’s battery, and that’s how wireless charging occurs.  

You must be wondering if having electromagnetic waves is okay, but how does the electronic device gets attached to the wireless charger?  

The answer is through magnetic resonance and electromagnetic waves. The wireless charger generates a magnetic wave. The electronic device remains connected to the wireless charger without the help of any wire. The bigger the coil is of the wireless charger, the more energy it will produce. The statistics show that more than 200 million chargers have been shipped for electronic devices.  

Other than generating magnetic waves, QI wireless charging is used for charging smartphones. In this, the current’s energy is directly transferred from the charger to the phone’s charging outlet with electromagnetic induction. An induction coil is used for this purpose. The induction coil is responsible for generating an electromagnetic field. The charging outlet in the smartphone converts it into electricity; thus, your phone gets charged by this procedure. Knowing the dynamics of wireless charging is so cool. Now you can flaunt your knowledge about Wireless charging out there!

Devices that offer wireless charging 

1. Smartphones such as the latest iPhone 13 offer wireless charging, other than this Samsung Galaxy S21 and Galaxy Z Fold 3, some variants of LG phones, Google Pixel, etc. 

2. Smartwatches such as the apple watch, high-end fit bits also offer wireless charging.  

3. Wireless mouse that is used for laptops has wireless chargers.  

4. Some parts of cars also get charged by wireless chargers, specifically the electronic parts.  

Disadvantages of wireless charging  

1. The major disadvantage of wireless charging is that it is super expensive. Generally, the wireless charger has to be brought separately when you buy the electronic device. Since the wireless charging technology is super fresh and new, it will remain an expensive affair for two-three years. After wireless charging becomes a common thing, then there is a chance that it may become affordable or comes completely free with the electronic device.  

2. Another disadvantage of wireless charging is that it generates a lot of electromagnetic waves. It directly affects your brain. Research studies say that excess usage of mobile phones and wireless chargers causes the brain to shrink, lowering your attention span, resulting in loss of concentration. Not even human beings but also animals get affected by these electromagnetic waves and magnetic waves. Birds such as sparrows have become endangered because these waves harm them a lot. Wi-fi is also a wireless internet device and is said to cause many harms to these birds. 

After reading these disadvantages, you must be against wireless charging but don’t feel bad about it because it also has many advantages. Inventions and improvements keep on occurring; everything is possible in the field of technology. It keeps on evolving to have a more sustainable approach towards saving the environment.  

It may be possible that we can have eco-friendly wireless charging in the future that generates fewer electromagnetic waves than usual and does not harm living beings.  

Advantages of wireless charging 

1. If you are a person whose wire charger gets torn off or tangled, then a wireless charger will prove to be very advantageous for you. It gives us the best alternative to carry the coil or the stand.  

2. The major advantage of wireless charging is that it is super handy and portable, very easy to carry. Charging is fun! Wireless charging no need to worry about plugging your phone for charging or connecting it with a wire. 

3. You don’t have to deal with broken cables anymore. This itself sounds so good. Bye, bye cable bites.  

Some facts about wireless charging  

1. You don’t even know it, but you may be using some of the electronic devices that have wireless charging. A great example of it is an electronic toothbrush.  

2. Wireless charging helps us create sustainable development- yes, you heard it right, in the case of cars that get electronically charged. It is said that wireless chargers reduce a lot of carbon dioxide emissions. Isn’t it amazing!  

3. Wireless charging was invented back in 1831 by Michael Faraday. He was a genius scientist but wasn’t able to popularize this technology at that time. 

The best gift was given to us in the 21st century, and the future is here. Who thought charging your electronic items would be so easy! By reading all this now, you must be fully aware of wireless charging. So will you prefer using wireless chargers in the future for your electronic items? According to us, it’s the best choice you can make!
