standby-power is ultra-low.
So How Does Wireless Charging Work?
The principle to charge your smartphone or smartwatch wirelessly is
simple: just put your phone on a charging pad or wireless charging sweet
spot and it starts charging. Very convenient, no need to connect a cable
first. But how does wireless charging actually work?
How can energy be transferred through air from one part to the other?
The way wireless charging works is by something which is called magnetic
induction. Firstly discovered in the 1830’s by Michael Faraday, he
discovered that when you move a permanent magnet in and out of a single
loop of wire, it induces a voltage. Linking electricity with magnetism.
Let’s explain by conducting an experiment...
Seeing is believing, do try this at home:
Take a permanent magnet – like the ones you stick on your fridge;
Connect a light bulb to a simple loop of copper wire;
Move the magnet quickly back and forth, bringing it closer and further
away from the loop;
The bulb will start lighting up a little!
So what just happened? Why did the bulb light up? By bringing the magnet
back and forth, you change the magnetic field experienced by the loop,
which induces a voltage in the loop. The voltage created is in some way
comparable to the voltage of a battery.
How does wireless charing work with induction?
Basically, wireless charging your toothbrush, smartphone or any other
device works similar as we just showed with the light bulb. In practice,
we don’t have a moving magnet but we do have another loop of copper wire,
a so-called induction coil, which will carry a changing current at high
This changing current generates the changing magnetic field. This part
of the wireless charging system is called the “transmitter”. The part
inside your phone, smartwatch or toothbrush is called the “receiver” and
is charged in the same way as the light bulb.
Wireless charging versus cabled charging
Is wireless power just as fast as power through wires? Well, it’s all
about power. A 5W wireless charging system can deliver up to 5W of power
to your phone battery. This is like a 5V/1A USB outlet and therefore it’s
just as fast as wired charging.
Latest developments in wireless charging enable to charge even faster:
up to 15W of power can be delivered to your phone. This will significantly
reduce charging time and “battery anxiety”.
Does your smartphone support wireless charging?
Most modern popular mobile phones will support wireless charging but you
will need to check with your device manufacturer to make sure your model
