The wireless revolution started in the 1980 and is gradually starting to come of age. A huge landmark of this revolution is Wireless Charging. Before now, when most people think about charging, wires always come to mind. Not anymore. Wireless charging has come and it is here to stay.


What is Wireless Charging?

Wireless charging can be defined as charging a device without having to physically plug it to a charging cable.


How it works?

Wireless charging works by using inductive charging. Inductive charging means using one electrically charged body to create (induce) electricity in another body, inside an electromagnetic field without the two of them touching.

Here is how it works. Inside the charger, there is a magnetic loop antenna (copper coil wound around a magnet). When electric current is supplied to the charger, it creates an electromagnetic field that induces current in a receiver coil on the phone.

There are three types of wireless charging:


1. Tightly coupled electromagnetic inductive coupling (non-radiative charging)
2. Loosely coupled electromagnetic resonant coupling (radiative charging)
3. Uncoupled radio frequency wireless charging (trickle charge)


1. Tightly coupled electromagnetic inductive coupling (non-radiative charging)

This type of wireless charging requires that the phone be placed exactly over the magnetic loop in the wireless charger. If it is not placed properly, the device won’t charge properly and sometimes not at all.


2 Loosely coupled electromagnetic resonant coupling (radiative charging)
Electronic magnetic resonant coupling means the addition of capacitors to both the magnetic loop antenna on the charger and the receiver coil on the phone. This increases efficiency and power delivery during charging. In this case, you do not have to place the phone at a particular spot so it can charge. You can place it anywhere on the wireless charging pad and it will charge just fine.
Radiative charging is better (i.e. faster and more efficient) than non-radiative charging.


3. Uncoupled radio frequency wireless charging (trickle charge)

This type of charging does not require the phone to be anywhere near the charger at all, but only within a certain range. This type of charging is very convenient but it is also very slow.


Wireless Charging Standards

There were three main standards for wireless charging. They were Alliance for Wireless Power (A4WP), Power Matters Alliance (PMA) and the Wireless Power Consortium (WPC).

The Wireless Power Consortium (WPC) which is made up of Google, Apple, Verizon and other big manufacturers became the dominant force in the market and put out the Qi (pronounced as ‘Chee’) standard. Qi is the most widely used charging standard in the world today.

In order to challenge WPC’s Qi, the A4WP and PMA decided to combine and form an entirely new standard. This standard is known as the Air Fuel Alliance (AFA). It is made up of big names such as Dell, Duracell, Samsung, Qualcomm etc. The charging standard known as Powermat was pushed by the AFA as a challenger to the Qi standard. The two charging standards are not compatible with one another.

Qi remains the main charging standard in the smartphone world. WPC also allows different OEMs to modify their Qi technology. This has given birth to the rise of several proprietary charging technologies that play well with one another. A lot of different charger and powerbank manufacturers have taken advantage of it. There are now different types of wireless charging pads as well as powerbanks in the market today.

Xiaomi have also taken things further with their Air charge technology which guarantees 5W wireless charging from every part of your home.

They're still struggling with fast charge, you wan come add wireless charge join?

You're weeeeeked

as in ehhn there gadgets are just quack... In this age when companies are introducing new features Transsion are still lagging behind..

But their diehard fans said they have flagship without neither water resistance or wireless charging.

What can I say?

it still baffles me on how there flagship don't support water resistant not to talk about using snapdragon processor in building there flagship gadget

Have you bought the phone and soak it inside waater to know that?

Well have seen reviewers do that

This is nice and am seeing only one brand in Nigeria that can develop this just a matter of time...

Can never? You be their engineer?

I wish brands can all adopt this technology

what are you even saying the ones they have built were you the one that built it for them?

lol, funny enough i wouldn't be shocked if they are one of the first to launch that feature.
