Obviously, many people are conversant with the phrase “QI CHARGING” but the majority have not even experienced it. Maybe due to their phones not supporting it, or due to the nonavailability of the wireless charging pad itself. We have various means of charging our phones apart from using the original wired charger. We can charge via a desktop charger, via a USB port of a computer, via a power bank, vi a power case and so on. One of the methods of charging supported devices without using the default charger is via a wireless charger. In the aritcle, i will explain all you need to know about a wireless chrger using my personal Samsung QI charager as a reference point.
Essentially wireless charging (a.k.a wireless power transfer) uses electromagnetic fields to safely transfer power from a transmitting source to a receiving device for the purposes of charging (or recharging) a battery. And as the name suggests, it does so without the use of a physical connection
Simple, efficient and safe, Qi charges or powers an array of devices, from smartphones to cordless kitchen appliances. Qi combines induction and resonance technologies to deliver a superior standard.
HOW DOES IT WORK? Wireless charging is based on the principle of magnetic resonance, or Inductive Power Transfer (IPT). This is the process of transferring an electrical current between two objects through the use of coils to induce an electromagnetic field.
CONCEPT OF WIRELESS CHARGING FOR PHONES, PHABLETS TABLETS
Perhaps the most well-known application of wireless charging is for smartphones.
In recent years, the number of phone manufacturers who have offered wireless charging capabilities have steadily grown, and for even those brands which do not have wireless charging functionality, you can acquire a myriad of external charging cases and sleeves which can enable wireless charging of these devices.
The current technology enables consistent, safe charging of single devices when placed accurately on a charging pad – characteristic of inductive charging systems. The leading standard worldwide for this technology is Qi, which is developed by the Wireless Power Consortium and is used by over 900 products worldwide.
As advancements continue to be made, wireless charging will likely become more ubiquitous and convenient. The development of resonant capabilities will continue to increase the appeal of wireless charging for consumers, while integrated transmitters into tables and bench tops will make it easier than ever to recharge our phones.
WHICH DEVICE CAN USE A WIRELESS CHARGER
- Samsung Galaxy S5 (via a charging flip cover)
- Samsung Galaxy S6
- Samsung Galaxy S6 Edge
- Samsung galaxy s7 and s7 edge
- iphone 7 via a special charging kit
- Samsung Galaxy Note 4
- Google Nexus 4-7
- Motorola Droid Maxx
- Nokia Lumia 920
- Nokia Lumia 928
- Nokia Lumia 929
- Nokia Lumia 930
- Nokia Lumia 1020
- Nokia Lumia 1520
The above list is not exhaustive, to view the exhaustive list please follow this link. We have Qi integrated phones and Qi ready phones. example, of qi ready phones, are Samsung galaxy s5, galaxy note 2, nokia Lumia icon, htc incredible 2,Motorola droid bionic and so on. You need an addon to be able to use wireless charging on qi enabled phones. As for qi integrated phones, you only need to buy the charging pad and start using it. If your phone is compatible with Qi charging, all you need to do is purchase a Qi charging pad.
HOW DO I USE WIRELESS CHARGING ON MY QI SUPPORTED PHONE?
Using my Samsung wireless charger as an example(Note: wireless charging is not same as charging over wifi) It means no wired connection between the phone and the charging pad. However, there is a physical wired connection between the charging pad and the power source. In other words, you connect your charging pad to a power source and then place your phone on it. An indicator light will come up once the phone is placed correctly. I have a picture of this below:
THE BENEFITS OF USING QI CHARGING
While I will not recommend that you substitute your wired charging for a wireless charging because each has its area of specialisation. For example, wireless charging does not yet support adaptive fast charging so if you want to make use of your fast charging capabilities, you will consider qi charging second option. That being said, let us look at the benefits of qi charging.
SECURITY: Especially if you get a very long usb charging cable like mine. You can be charging your phone on your desk and you won’t thinking twice befoe picking it up when moving away from your desk no matter how much of a haste you are in. On the contrary if yu were to be using a wired cable, you may think unplugging the charger alone is one hell of a time-consuming task. You can also be free from accidental damages to your wired charger ifyou use qi charging more often
YOU SAVE MONEY: We all know that the changing cables that comes with our phones are fragile. In no time, they get ripped apart and you start looking for money to buy a replacement. if you support your original charger with wirelss charging, yu can save your origina usb cable for a long time to come. remeber you need this cable to also transer data
YOU CAN ALSO SAY FAREWELL TO USB CORDS FOR CHARGING: Frustrated with messy, often incompatible cables? Qi charging technology cuts the cord for your devices – finally, they are truly wireless
IT AFFORDS YOU MORE PORTABILITY: You can move more freely and use on hand to charge your phone when using qi charging system. you only need to pick and drop as against plug and unplug that is associated with cord charging.
IT IS MORE RELIABLE: With qi charging you know that you can always count on it because you can test the pad to see if it is functional befoe you start charging. This is not always the case with cord charging. at times a USB charger will charge you phone halfway and fail to continue charging it. other times, your usb charging port may be too loose to secure the cable. With a charging pad, you can still charge your phone even if your charging port is entirely damaged.
