Wireless charging has been around for quite some time, but as of 2017, it has finally acquired the universal standard support from all commonly available smartphones in the market produced both for IOS and Android. The key feature behind Wireless (or inductive) charging is electromagnetic fields that allow users to charge their mobile device wherever they are without having to take out their charging cable. This process of electromagnetic induction is efficient, easy and will revolutionize the way we charge our phones in the years to come.

How does Wireless Charging Work?

1. Mains voltage is converted into high frequency alternating current (AC)

2. The transmitting circuit creates a loop by sending the alternating current to the transmitter coil.

3. The alternating current flowing within the transmitter coil creates a magnetic field, which extends to the receiver coil. (The size of the coil, affects the distance of the power transfer. Bigger coils enable a greater distance a charge can travel.)

4. The magnetic field generates power within the receiver coil of the device.

5. Current generated within the receiver coil begins to flow around the magnetic field.

6. Ultimately power is converted into direct current (DC) by the receiver circuit and enables charging the battery of the device.

Fast Charging Vs. Normal Charging

There are different types of wireless charges available in the market today. The main difference between them is the output indicated in Watts. Common wireless outputs vary within the rage of 5W, 10W and 15W. Most smartphone devices until now support 5W charging but the new generation mobiles come with a built-in capacity to support up to 7.5/10W.

Higher the watts the faster your phone will charge. When using a fast charger your phone will indicate on the screen it’s enabled for fast charging.

Wireless Super-fast Charging

Devices that support Fast Charging:

• Samsung Galaxy S7 & S7 Edge

• Samsung Galaxy S6, Galaxy S6 Edge & Galaxy S6 Edge Plus

• Samsung Galaxy Note 5

• LG G4

• Nexus 6

• Moto Droid Turbo

• Nexus 5/7(2013)/4

• Nokia Lumia 1020/920/928

• iPhone X

3 Coil Charging

One often thinks that a 3-coil charger will amp up the charging speed. Surprising it does no such thing. It takes a single coil charging coil to power your phone. The purpose of a multi-coil charger is to allow your device more room on the charging pad. Extra space enables phones to connect properly make the induction efficient and provide a better wireless charging experience.

But is it safe?

With the news of harmful effects of radiation buzzing around, a concern regarding the safety of the charges is obvious. Built with features that are designed to provide safety first, all branded wireless charges are very safe to use. Here’s what you need to know:

Latest Wireless Charging

Overcharge Protection

When the battery is fully charged premium brand chargers will immediately stop charging.

Over-Current Protection

In case of a power surge or even lightning strike the charger is built to make sure you and your mobile device stay safe by sending only optimal charging current.

Short Circuit Protection

The charger shuts the device down in case of a short circuit to prevent any mishap.

A Standby Current of Maximum 0.3W When Not in Use

All premium brand wireless chargers have a low power consumption mode when not in use. Low-quality chargers consume twice as much energy when not in use, harming your pocket and our environment.

Foreign Object Detection

Most branded wireless chargers have built-in FOD (foreign object detection) to make sure that the wireless charger will only charge your mobile device. Bad quality chargers are unable to detect other metal objects like pens or coins. This could lead to permanent damage to the wireless charger.

Temperature Control

Wireless chargers have a built-in temperature control to make sure the device does not overheat while charging.

Durable A-Grade Components

All good quality wireless chargers are made with A-grade components to meet all European standards. These chargers are safer and more durable to use in the long run.

All branded wireless chargers are tested by official institutes for CE and therefore in compliance with the strict regulations set within the EU.


What is wireless charging?

Wireless charging is the process of transferring power through electromagnetic induction. Unlike traditional chargers that require the energy to travel through a cable wireless chargers receive their power from an electromagnetic field. All you need is a charging mat and a phone that is compatible with it.

Does the charger get hot?

Like any other charger, wireless chargers get warm when they charge. However, these charges are in-built with chips that protect your charger and phone from overheating.

Is overcharging possible? Does it damage my device?

It is perfectly safe to keep your device on the charger even when your phone is fully charged. Via trickle charge, a small amount of power will be charged when your phone drops below 100% for a safe charge.

Are wireless chargers waterproof or water resistant?

We learned in school that water and electricity is a bad combination. So it best to avoid putting a wet phone on the charger or getting the mat wet.

How does the charger know how much voltage my device needs?

New gen wireless chargers are inbuilt with smart chips that recognize the exact amount of voltage needed for different devices. Higher voltage only will be switched on when a higher capacity is recognized.

What happens in case of a power surge?

Wireless chargers are connected to a socket, which means they can be affected by a lightning strike or fluctuating power supply. However, they cannot transfer these increased voltages to your device. So it is actually much safer to charge your device through a wireless charger than with a cable and socket.

Is wireless charging faster or slower than cabled charging?

That depends on what wireless charger is being used and what the charging speed is of the cabled charger. In general cabled chargers are still faster as they can transfer more power in a shorter period of time. Most phones support 5W wireless charging which equals 1A per hour. The newest generation Samsung S8 and iPhone X support 7.5W wireless charging which equals 1.5A per hour.

How do I place the phone on the charger for it to charge?

The wireless charging connection is made between electromagnetic coils that are both in the charging base as in your mobile phone. The coil of your mobile phone needs to be close to the coil in the charger in order to establish the connection.

Which phones are compatible with wireless charging?

Below a list of popular models that are compatible with wireless charging:
