Inductive charging – how does it work? The advantages and disadvantages of such a solution

What is the most significant advantage of portable electronic devices? Their mobility, of course! You don’t have to worry about cables limiting you when using your smartphone. Well, maybe only when the phone needs charging. In such a case, using it becomes difficult, and the convenience comes to an end. That is precisely why inductive chargers have been created. Is it worth using them? Discover all the advantages and disadvantages of such a solution!

Here’s what you’ll find out from this article:

• how inductive charging works,
• what are the advantages and disadvantages of wireless charging,
• how to check if your phone is ready for wireless charging.

How does an inductive charger work?

Wireless chargers are based on the principles of electromagnetic induction. A coiled wire inside the device acts as a transmitting coil. When alternating current flows through it, an electromagnetic field is created. Both the number of coils and the parameters of the current itself have an impact on its strength.

The mobile device must include a proper receiving coil for wireless charging to be possible. It is located about half the height of a smartphone. When it comes into contact with the electromagnetic field, the coil induces a current that is used by the phone to charge the battery.

Due to electromagnetic field interference, the phone should be located as close to the charger as possible. Even a slight change in its position may weaken the current flowing into the battery.

You can come across various types of inductive chargers:

• flat – simple pads on which smartphones are placed in a horizontal position,
• standing – these are models in the form of stands on which phones are placed at an angle (this makes using the smartphone during charging easier),
• car – built into the holders in which smartphones are mounted while driving.

Advantages and disadvantages of wireless charging

At first glance, an inductive charger may seem like a very functional device that increases the comfort of using a smartphone. One cannot deny its numerous advantages. However, before purchasing such a device, it is also worth getting acquainted with its disadvantages. So what are the pros and cons of inductive charging?

Wireless charging and its benefits

• Charging convenience – no need to worry about tangled cables.
• Convenient access to the phone – you do not have to connect the device to a source of electricity located in hard-to-reach places or remember to unplug the charger.
• Compact size – despite its functionality, the wireless charger does not take up much space.
• High safety level – all cables are inside the charger, and the power cable does not need to be disconnected each time it is used.
• Compatibility – unlike ordinary power supplies, an inductive charger can power up any phone battery (which includes this function) regardless of the type of used port (USB-C, Lightning, micro USB).
• Attractive design – the inductive option looks more interesting than a regular corded charger.

Wireless charging and its disadvantages

• Longer charging time – due to energy losses, the speed of inductive charging is usually lower than using a traditional charger.
• Less freedom to use the phone when charging – you can conveniently pick up your smartphone from the charger and put it back, but you have to consider that the charging process will be halted.
• A high temperature – the created magnetic field generates large amounts of heat, unnecessarily heating the battery. For this reason, models with active cooling are also available, but their fans may turn out to be quite noisy.

Does my phone include inductive charging?

If you want to take advantage of a wireless charger, you first need to ensure that your smartphone includes this feature. To do this, check whether your device supports the QI standard. It is a shared technology that has been developed to unify various methods of inductive phone charging.

If it turns out that your smartphone does not support the QI standard, nothing’s lost! You need a special adapter that connects to a power socket and slides under the flap or phone case. It is a small and very convenient device in the form of a thin bag with a receiving coil. When it is within the range of the electromagnetic field, it starts to transfer power to the smartphone battery via a traditional connector.
