Here Are Three Ways to Stay Safe While Using Wireless Charging

Wireless charging

Charging a smartphone nowadays can be done without having to be connected to a device that is directly connected to an electric current. Currently, smartphone charging can be used simply by bringing the smartphone device closer to a device, without any connecting cables at all. This technology is called wireless charging.

A tool to support wireless charging is called a wireless charger. This tool is now widely found in the market. This is in line with the number of smartphones that already support wireless charging technology. As for now, wireless charging is still not a common thing, it’s exclusively limited to high-end devices.

So, if you have a smartphone that supports wireless charging, be happy because you can charge the device without being connected to a cable. Now, if you still couldn’t grasp the whole idea of wireless charging, no need to worry because we’ll talk you through it. But before that, let’s get acquainted with the wireless charger first.

About Wireless Charging

As previously mentioned, a wireless charger is a device that allows a smartphone to be fully charged without using a cable, or wireless charging. As the name implies, which means charging without using a cable, or wireless.

Even without a cable, charging must still be done close together or at a short distance between the smartphone and the wireless charger. This can be done because the wireless charger has a working principle of delivering electromagnetic induction to smartphones.

Inside the wireless charger, there is at least one coil whose function is to present an alternating electromagnetic field. The receiving device, or smartphone, will receive the electromagnetic field and convert it into an electric current so that it is possible to charge the battery.

Inside a charging pad, there are several components as follows.

  • LED light that functions to detect foreign objects
  • Non-slip surface for safety.
  • Transmitting coil section for wireless charging
  • The design section is fanless so that during operation it is not noisy
  • The working part of the wireless charging chipset incorporates various features
  • Thermal protection sensor
  • Circuit section for foreign object detection

Not all wireless charger pads have the exact same design and components. But in principle, wireless chargers generally have several of these parts.

Wireless charging technology has two technologies. The first is magnetic field induction and the second is magnetic field resonance technology. The presence of these two technologies resulted in several wireless charging standards depending on the particular consortium. The following is an explanation of the standard wireless charging technology.

Although it doesn’t have any relation with wireless charging, keeping your device safe is also important. With the rapidly growing technology, the risks of cybersecurity are also rising. And to counter them, you can buy and download VPN for all your devices. Look for a VPN service that may support more than one device to make it more practical and affordable.


The first consortium was born by the Wireless Power Consortium. This consortium came up with a standard called Qi (pronounced “Chee”). This technology presents wireless charging with a magnetic field induction standard. In further developments, Qi also applies magnetic field resonance technology.

The Qi standard itself is the most popular standard because it is supported by various leading mobile phone manufacturers. There are several companies that are using this consortium, including Google, Apple, LG, Huawei, and many more.


The second standard is Powermat. This Powermat was initiated by the Power Matter Alliance or PMA. This standard applies magnetic field induction technology.

Despite adopting the same technology as Qi, PMA is not Qi-compatible. So, mobile phones that support Qi wireless charging cannot be charged using a wireless charger pad that supports PMA technology. However, there are several smartphones that also support these two technologies, namely Qi wireless charging and PMA wireless charging.


The Alliance for Wireless Power or A4WP is an alliance that issues wireless charging standards with Rezense technology. This standard uses a resonant magnetic field to transfer power.

The advantage of this standard is that the phone does not need to be directly above the wireless charger pad. In fact, one wireless charger pad can charge several smartphones at once.

Air Fuel Alliance

Air Fuel Alliance is a standard created by A4WP and PMA collaboration. This collaboration is intended as a challenge for Qi technologies. Why? Because in the market, Qi technology is a popular wireless charging technology.

In the market itself, there are indeed many smartphones that support wireless charging technology, both Qi and others. An example is the high-end mobile phone Samsung Galaxy S10 series, which already supports Qi and PMA wireless charging standards.

Indeed, most phones that support wireless charging technology are high-end phones. Middle and lower-class smartphones can actually use wireless charging technology. It’s just not built-in like high-end phones.

Smartphones that do not support built-in wireless charging require a receiver or case that contains a receiver or you can also use a universal adapter. With the use of a universal receiver or adapter, even ordinary cell phones can change to support wireless charging technology.

The Three Ways to Stay Safe While Using Wireless Charging

After knowing the ins and outs of wireless chargers, then we will discuss how to use wireless chargers. Take a good look at the tutorial below!

1. Prepare Smartphones and The Proper Wireless Charger Devices

The thing that needs to be prepared, of course, is a smartphone or smartphone that supports wireless chargers and wireless charger devices. For this tutorial, as an example, the smartphone used is the Samsung Galaxy S8. This smartphone supports wireless charging. The tools for the wireless charger are as follows.

If the wireless charger used turns out to already support fast charging or it already supports fast charging. This tool itself is a wireless charger which is a purchase bonus when you first bought the Samsung Galaxy S8. Although the wireless charger types can be different, they basically work in a similar way.

2. Carefully Connect the Wireless Charger to Mains

This wireless charger is a type of wireless charger that requires power. So, it’s not a type of wireless charger that works like a power bank, it’s charged first, then it can be used to charge a smartphone. Therefore, this wireless charger requires an electric current using an adapter or smartphone charger. Other types of wireless chargers on the market are also more or less the same.

3. Keep the Phone above the Wireless Charger

After connecting to electricity, keep the smartphone above the wireless charger and position it properly. If stored properly, there will be a sign stating that the smartphone is being charged.

Fix iPhone Battery running out quickly

Not only when the smartphone is standing when the smartphone is positioned in landscape form, but the phone battery can also be charged with this wireless charger. The important thing is the right position.
