Obviously, Qi wireless charge has not come to replaced wired/cable charging. However, there are more than 10 reasons why you should get yourself a wireless charging device. This post look at wired vs wireless charging vis-a-vis the benefits of using one over the other.
There are various methods of charging a phone. One method is using the cable and adapter, another method is by using the charging cable connected to a USB port, now we have wireless charging. Apparently, the only way to charge a phone without connecting the charging cable to the phone is via Qi wireless charging.
What is Qi Inductive Wireless Charging?
Qi from the Chinese word qi) is an open interface standard that defines wireless power transfer using inductive charging over distances of up to 4 cm (1.6 inches), and is developed by the Wireless Power Consortium.
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. This ranges from smartphones to cordless kitchen appliances and so on. Qi combines induction and resonance technologies to deliver a superior standard.
How does Qi Wireless Charging work?
Wireless charging is based on the principle of magnetic resonance, or Inductive Power Transfer (IPT). This is the process of transferring electrical current between two objects through the use of coils to induce an electromagnetic field.

Concepts of Wireless Charging for Smartphones
It is not surprising that 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 has steadily grown. And as for those brands which do not have wireless charging functionality, you can acquire a myriad of external charging cases which can enable wireless charging of these devices.
Currently, we have wireless charging that can fast charge your device, we have one that can share power between two phones, there is also one that can charge at least two compatible devices simultenously.
Wireless charging technology enables consistent, safe charging of single devices when placed accurately on a charging pad. This is the characteristic of inductive charging systems. The leading standard worldwide for this technology is Qi and is used by over 1000 products worldwide.

Wired vs Wireless Charging: The Benefits of Using QI Charging over Wired/Cable Charging
While I will not recommend that you substitute your wired charging for a wireless charging because each has its strengths and weaknesses. let us now compare the benefits of Qi charging.
Security of your Device
You can add some element of security while charging your phone. For example, you can be charging your phone while it is in your pocket with AirVolt.
Alternatively, if you get a very long USB charging cable like mine. You can be charging your phone on your desk while the wall adapter is plugging into a socket far away from where you are sitting or lying. This allows you to keep tab of your phone at all times. On the contrary, if you were to be using a wired cable, you may think twice before charging your phone in an insecure environment.
Charge your device wirelessly without connecting any receiver to a power source
Wireless charging Powershare popularised by Samsung is a technology that can allow you to charge any Qi-compatible device with a Samsung s10, s10e, or s10+ phone. When using this feature, you use a phone to charge a phone. In other words, you don’t need any power source or cable.
It is overall safer to charge your phone wirelessly
Especially relevant for those who love charging while in bed. It is safer(health-wise) to place your charging pad on your bedside table and charge your phone. Anything can hardly go wrong with this habit.
You can Move Around or use your Phone While Charging
A new wireless charging device in the person of AirVolt allows the user to move around while holding the mobile phone while charging. Obviously, your movement is restricted while using a wired charging.
You can Save Money by Using Wireless Chargers
We all know that the charging cables that come 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 wireless charging, you can save your original USB cable for a long time to come. remember you need this cable to also transfer data
With a QI wireless pad, you can say Farewell to USB Cables for Charging
Frustrated with messy, often incompatible cables? Qi charging technology cuts the cord for your devices – finally, they are truly wireless
It Offers you more Mobility
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 than Wired Charging
With Qi, charging you know that you can always count on it because you can test the pad to see if it is functional before you start charging. This is not always the case with cord charging. at times a USB charger will charge your 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. Generally, a Qi inductive chargers are easier to troubleshoot when not working.
Wireless charging support 3rd party charging cables and adapters better than wired charging
Currently, I am using a 3rd party cable to power my Samsung duo wireless charging pad without issues. If I try the same with my phone, I may not get the desired result.
With Wireless Chargers, you can minimize accidental damage to your phone
It is safer to pick up your phone of a charging pad with one hand. This is convenient and it gives r=little room for mistakes or accidents. On the contrary, you need your two hands to unplug your phone from the cable otherwise, you risk damaging its charging port, the cable or dropping the device.
Advantages of Wired/Cable Charging over Qi Wireless Chargers
There is nothing that has advantages without disadvantages. Here are the reasons while you may still choose to stick to your OEM cable and adapter for charging your phones.
- The secure feeling of using what your phone’s maker recommends out of the box. You sure know that nothing can go wrong using your original charger and cable.
- Cable charging faster adaptive charging is faster than that of Qi charging. Same way the fastest wired internet connection is faster than the fastest wireless hotspot.
- Mobility and portability are easier with your wired charger. Nowadays, our adapters are getting smaller while wireless charging pads are getting bigger.
- I will say the phone charging adapter can be more durable than most charging pads under the same use. I have many adapters that outlive my phones.
Types of Qi Wireless Chargers
- True wireless chargers, for example, the one by Airvolt: This device enables long-distance wireless charging with a maximum transmission distance of up to 12 meters. In other words, you can charge your phone while you use it.
- Standard/regular wireless charging pad. With standard wireless charging pad, you can charge your compatible Qi-compatible devices, without the need to plug your device into a wall charger or USB port. See below
Universal Wireless Charger Duo, Fast Charge Stand & Pad. A good example is the one by Samsung. This is the overall most powerful of them all. With this device, you can fast charge two phones at once. Pad charging also supports charging for Gear S3 and apple watch. It will also support later Samsung smartwatches
- Last but not least, we have Samsung wireless PowerShare charging technology. With the new Wireless PowerShare feature, the Galaxy S10 can share its power to help charge another phone or watch. All you need to do is place the two devices together. The image below explains this further
How to use Wireless Charging on QI Supported Phones
Using my Samsung wireless charger as an example(Note: wireless charging is not the 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:
