Imagine a life where you won’t have to walk around with four different chargers for every one of your smart devices. Where you won’t have to ransack your bag for that particular USB cable; where you won’t have to keep twisting your cable at the perfect position to ensure your phone actually charges.
It happens that even the day when you arrive at your favorite coffee shop with all your chargers, all the power outlets will have been inevitably taken. Too much stress, right?
Not to worry because technology has brought us a solution to all these woes. You must have heard the phrase wireless charging. But, what exactly is this? Simply put, wireless charging is the act of charging your smart devices without cords and outlets.
This concept has been in existence since the 19th century, when electricity explorer Nikola Tesla illustrated magnetic resonant coupling—the act of transmitting energy across the air by establishing a magnetic force between two circuits, a receiver and a transmitter.
However, this technology has been without many practical uses, except for a selected number of electric toothbrushes. Today, there is thousands of wireless charging technologies in existence, all aimed at powering everything including smartphones, laptops, kitchen appliances, and cars.
This technology is making an impingement into different industries including the automotive, healthcare, and manufacturing because it promises increased advances and mobility that could allow even tiny IoT devices to get powered while they are many feet away.
The below facts about wireless charging will help you understand this technology better.
Wireless charging technology has been around for quite some time now
As stated above, wireless charging technology has been in existence since the 19th century. In 1820, Danish physicist Hans Christian Oersted, using a magnetic compass and electric current, discovered that electric currents have the ability to create a magnetic field.
The history of this technology didn’t stop there though, ten years later, Michael Faraday, a legendary English scientist, invented electromagnetic inductive wireless charging. Later on in 1890, Nikola Tesla invented the greatest breakthrough for this technology.
Using his famous Tesla Coil, he did a demonstration on wireless electricity transfer. With a high frequency alternating current, Tesla wirelessly lit up a bulb right across the room. So, yes, even back then, people already knew the advantages of wireless charging. Check price of wireless 20000 mAh Power Bank Here
Wireless charging is friendly to you and the environment
The common misconception is that emissions from the wireless charging system are harmful to human health. But, the truth is that these emissions are not that powerful and they have a low level that is not enough to affect human beings.
The World Health Organization (WHO) has even confirmed that being exposed to tiny amounts of EMF emissions cannot harm humans. Therefore, wireless charging doesn’t really cause health concerns associated with high levels of EMF emissions such as depression, nausea, low libido, headache, and fatigue.
Also, by minimizing the emission of CO2 by thousands of tons yearly, and by reducing battery junk created by the continuous replacement of disposable batteries, this technology actually helps create a more sustainable environment.
Wireless charging has many common uses
Wireless charging can be flawlessly integrated into everyday technology, and, we are not just talking about your smartphone. There are the wearables, drones, electric vehicles, and more.
At some point, we have all left home with the wrong charger; we have had to hold our device at a particular angle to ensure it charges. Well, wireless charging allows our devices to be easily charged in one place, and yes, it’s without the mess created by tangled cords. In the current world of “connected devices,” wireless charging is quickly becoming inevitable.
Wireless charging can be divided into three broad types
David Green, an IHS Markit Research Manager, categorizes wireless charging into three broad types. There is RF (uncoupled radio frequency) wireless loading that allows gush charging at several feet distances; charging pads that utilize non-radiative or tightly-coupled electromagnetic inductive loading; and charging bowls or via-surface charging that uses radiative or loosely-coupled electromagnetic resonant charging with the ability to transfer a charge at a few centimeters away.
Both loosely-coupled resonant and tightly coupled inductive charging operate on a similar concept: a time-changing magnetic field kindles a current in a secured loop of wire.
With wireless charging, you can charge all your devices at once
Think of your Wi-Fi router and how it transfers the internet to your cellphone, computer, or wearable wirelessly. Well, that’s exactly how wireless charging, especially radio frequency (RF) works. With wireless charging, you don’t need to use five different chargers for your five different electronic devices, so say goodbye to those wires. Simply drop your device into a bowl, box, or cup, and the wireless power transfer will charge all your devices.
Wireless chargers do not hack personal information
Now that wireless charging has become readily available in public spaces including airports and coffee shops, rumors and concerns have been going round about the privacy of individuals who use this charging system in public places. It is good to note that until now, there haven’t been any reported instances of hacking of personal information through wireless charging.
Wireless charging doesn’t damage your device
Wireless charging will not cause any damage to your phone or its battery, provided you use an accredited high-quality wireless charging product at all times. However, other factors may lead to phone damage, the primary one being excessive heat due to poor ventilation (for instance charging a device in tight spaces). Also, using low-quality or fake wireless chargers could greatly harm your phone as such systems may not have gone through quality checks and strict testing.
The healthcare industry would greatly benefit from wireless charging
If you have ever tried to replace the battery of a hearing aid, then you already know that this is not an easy job. What’s more, the hearing aids market majorly caters to the elderly. Now, picture an elderly person who has to keep changing the battery of their hearing aids on a daily basis.
This seems to be an incredibly cumbersome task that this person will have to perform for the rest of his/her life. Now, instead of going through all the stress of replacing an old battery, what if the elderly person could just put their hearing aids in a box or bowl as they go to sleep and wake up in the morning to fully charged wearables?
The healthcare industry would greatly benefit from wireless charging because of how effortless it would be to charge small wearables that are utilized frequently in healthcare. Besides, drones are becoming more and more useful in the healthcare field as they help in delivering medical backing to other countries. Drones require wireless charging to remain truly autonomous!
It’s possible that you are unknowingly using wireless charging
An electric toothbrush charges on its stand through the wireless charging technology to avert probable electric shock due to the proximity to water.
Wireless charging, like everything else, has its downsides
Even with its many benefits, wireless charging has its disadvantages too. It is not possible to use your phone while it’s charging, and the charging is slightly slower when using wireless system than when the phone is plugged in. While magnetic induction charging seems to be faster compared to magnetic resonance, your two devices need to be more aligned and closer for this to work.
Don’t let the small inconvenience discourage you from using this technology, though. Once you get to use it, the extra convenience can really be satisfying. Just buy 2 or 3 pads and charge your phone, whether at home, in the car, or at the office. In case you want to check a text or take a call, you can easily pick up the phone and put it right back without pulling out a cable.
Wireless charging is not yet mainstream
Despite all the benefits that wireless charging brings, it’s shocking that this technology has not been assimilated in every part of our lives. One of the reasons for this is the lack of regulation in the market. The available technologies have been made in a way that devices cannot work with just any sort of charging station—each device requires its own charging station.
From alarm clocks to watches and earbuds, it seems like more and more everyday products are revolutionizing into smart technology. It’s true that smart technology makes our lives better; who doesn’t desire a watch that can keep tabs on your daily fitness levels and answer your text messages as well.
There is just one problem; how do you charge all your smart devices at once, without the need for more cords, more cables, and more wires? Wireless charging comes to solve all your woes. From seamless integration to convenience, wireless charging is indeed the future of all smart devices. In the future, the use of a charger may even be obsolete—it would be possible to charge your phone over the air. You will only need to be in close proximity to a charger.
