Here’s How Wireless Charging Becomes Possible

Charging any electronic devices means helping them regain their energies. Doing the same for mobile phones means making your mobile phones more sustainable in the long run. These days, you do not even need wires to charge your mobile phones. Thus, this article introduces you to the wireless charging method.

Mobile Phone Charging – The New Way

True to its name, wireless charging means charging mobile phones without needing to plug the wires into electrical sockets. People from many parts of the world use power banks to connect their mobile phone’s USB directly to the devices while charging the battery.

The Electromagnetic Spectrum

We can explain the ways power banks and other similar wireless charging methods through understanding the ways the electromagnetic spectrum works.

It is when the power banks (or other wireless electrical sources) go in contact with the mobile phones that it generates some kinds of electromagnetic powers. The USB cables act as the power connectors between the two elements depending how new or used the cables are.

Transmitter Designs for Mobile Phone’s Wireless Charging Interfaces

The circuit always comes on top of the current when it comes to the essential mobile phone’s wireless charging transmitter design interfaces. Bus, DC and AC machines, are three elements that should be present in the current settings that the circuits become the top of them.

At least, such transmitter designs can charge 3,000 mAh for a single mobile phone device. Even though there are no exact measures on the minimum and the maximum charging values, the 3,000 number is considered close to the minimum mobile phone charging values.

What is Rectannae?

Generally, rectannae is the abbreviation of a rectifying antenna. It is a specific receiver antenna to transform electromagnetic energies into one-way current electrical resources. Any wireless charging methods will involve these antennas since these antennas transmit electrical power sources through a radio wave.

How does a Rectannae work?

You know both AC and DC machines are parts of how a Rectannae works in charging the mobile phones without wire connections when you read the whole machines. More specifically, the diodes in a Rectannae fixes the AC to produce DC outputs. In return, those outputs power the connected loads across the devices.

You can witness the process of a working Rectannae in RFID tags, proximity cards, and contactless smart cards. Those three cards and tags have the circuits placed on top of the current boards. Even so, these wireless charging methods often have lighter weights, yet with more power capacities in mAh to charge mobile phones.

All about the Receiver designs you should know

Sometimes, a mobile phone has an attached receiver. This tool’s purpose is to let you charge the mobile phone without having to plug the charging cables into any sockets. This tool may resemble the conventional power bank at a first glance.

Yet, you should attach the receiver to the back part of your mobile phones to execute their functions. Additionally, making sure that the Wi-Fi-like images face upfront instead of being flipped back inside the mobile phone’s battery part.

Why do many people prefer Schottky diodes?

Lower turn-on voltage uses, faster recovery times than the rest of the diodes, and the fact that they rarely lose their energies, make Schottky diodes become some of the most considerable alternative solutions for charging mobile phones without using wires.

Radio frequency mixers, detector diode applications, power rectifier applications, power or circuit applications, solar cell applications, and clamp diode applications, are some Schottky diode subtypes that we often see. Most of these Schottky diode types have high current densities that they can charge the mobile phones for a long time.

All about sensor circuits in the wireless charging technology

Sensors in the wireless charging technology act as the reminders for the “chargers” and the mobile phones to charge without using any wires. Sensors connect to the circuits that transmit the electromagnetic energies and become the “mediator” for the sensors, chargers, and the mobile phones.

So, the wireless charger will be faster to transmit, connect, give, and receive electrical energies when the sensors are working. The same thing applies for the circuits that are attached to the sensors.

Can you convert a phone to wireless charging?

Absolutely, yes. There are two ways you can do in converting your mobile phone to be able in performing the wireless charging functions:

  1. Use a power bank. Many people in developing and Asian countries use this method. Then, again, there are power banks with NFC stickers for charging. You can place your mobile phone on top of the NFC surface to perform this task.
  2. Use your phone case to hold the receiver. Do not forget the charging pad to help charge the phone when you use this #2 way.

Is there an app for wireless charging?

Yes. Aircharge Qi has launched the official wireless charging app that connects to over 5,000 global Qi charging hotspots since at least two years ago. Many Apple users use this charging application, even though Aircharge Qi is also available through the Play Store.

Aircharge Qi works as long as your installed application works well and you’ve found the charging venue. Follow the step-by-step directions from there on, and you will be fine to go.

What is the cheapest phone with wireless charging?

Given Samsung Galaxy series’ expensive price ranges (compared to Xiaomi and other Chinese brand competitors), it is surprising that Samsung Galaxy S9 and S10E become two of the most economically-priced smartphones with the considerable wireless charging technology.

WPC and PMA are the two wireless charging technologies that Samsung Galaxy S9 supports. On the other hand, the slightly newer version, Samsung Galaxy S10E, has the reverse charging feature. Such an additional feature lets you use your S10E phone to charge another device. You can even charge your microwave with your S10E phone.


The wireless charging technology applications in mobile phone products do not stop in using power banks. Even when you do, the power banks should have some sort of NFC stickers.

The NFC or contactless technology becomes more crucial as these sensors can transmit the electromagnetic energies to the mobile phones even without any plugged cables.
