Everything About Wireless Charging

Wireless charging, as you can guess, is cable-free, modern, and the most convenient way of charging electronic devices. It is also known as Inductive Charging, and it requires only two things:

• A wireless charger usually comes in the form of a mat, stand, or puck that connects to a nearby power source.
• An electronic device, compatible with wireless charging. This may include your smartphone, smartwatch, or any other device.

With these two things in hand, you’re all set to charge. Just place your smartphone or another device onto the wireless charger and let it do its work. The charging will start immediately, and your device will be fully charged within the stipulated time.

Why Wireless Charging

Wireless charging is getting rapid popularity among smartphone users. Let’s take a look at some of the reasons behind its growing popularity:

Convenience

Wireless charging allows you to connect your device to a charger more quickly and easily. With a wireless charger, you can connect your device within a second, even without freeing up your other hand to find a cable and set it in the right direction before plugging it in.

Moreover, wireless charging protects your smartphone from damage caused while connecting and disconnecting a cable. Wireless chargers last longer than cables and make you save your money on buying new charging cables that wear and tear.

Stay Charged

Smartphones have become an integral part of our personal and professional life. Due to the increased use, we often have low or empty battery issues. But wireless charging ensures our phones stay charged all around the clock as it offers a convenient way of giving our phones a little battery boost every time we put them down.

Speed

A myth prevails among users who basically fear change that wireless charging is slow. That’s not true.

So, don't believe in myths or false information. Wireless chargers charge your phone as quickly as the conventional chargers that usually come with your smartphone and are known among users as a ‘genuine charger.’

Multiple Utilization Scenarios

Car

We all know how troublesome and risky it is to connect a car charger to your phone. In fact, this is one of the main reasons behind so many road accidents that the driver, while trying to plug in the cable to their phone, loses attention and bangs.

With a wireless car charger, you can keep your battery levels up while driving and without any risk.

Desk

Wireless charging gives you the freedom of charging while you’re at work. Just place the charging pad on your desk, and stay charged without going through the trouble o16f reaching out to a wall socket and plugging in the cable.

Nightstand

You can put your wireless charging pad on your nightstand and keep your phone connected to power. When you need to use your phone while you're in bed, pick it up, and place it again on the charging pad after using it.

On The Go

When you’re on the go, you don’t have the time to charge your phone using a cable charger as it will need you to sit near the phone. On the other hand, a wireless portable charger or a wireless power bank allows you to charge up even if you’re on the go.

Case Compatibility

If you’re using a case for your smartphone, you may not be able to connect standard cable chargers. To be able to charge, you’ll have to remove your phone from its case first. A wireless charger doesn't require that, as wireless chargers work through most plastic phone cases up to 4mm.

How Does Wireless Charging Work

To understand how wireless charging works, we have to look into the types of wireless charging.

Shop Wireless

Inductive

This type of wireless charging requires you to build a physical connection between your phone and the wireless charger. To start the charging, you’ll have to connect and align the charging coils inside your phone and wireless charger.

Resonant

Resonant wireless charging provides you the freedom of keeping your phone away from youra wireless charger. It doesn’t require the two to be touching each other, but keeping them within a specific proximity.

How Inductive Wireless Charging Works

Inductive

Wireless charging works by simply creating an electromagnetic field. This electromagnetic induction works in the following way:

The charging pad contains a transmitter coil that sends out signals.
These signals look for receiver coils encased in your smartphone.
Upon connection between the signals and receiver coil, electromagnetic induction begins.
Electrons in the transmitter coil start to flow around.
This flow of electrons creates a magnetic field.
Upon sensing the magnetic field, electrons in the receiver coil start to flow around.
This flow of electrons in the receiver coil is basically the electricity that charges up your phone.

Safety & Qi Wireless Charging

Qi is a popular wireless charging standard developed by the Wireless Power Consortium. This standard -- that fastly charges iOS and Android devices over distances of up to 4 cm -- is supported by 215+ popular leading companies, including Apple, Evolved Chargers, Philips, and many others. Qi aims at delivering wireless charging with utmost ease and safety while ensuring compatibility for all devices.

Foreign Object Detection

Inferior chargers may not be able to detect whether foreign objects (such as keys or coins) are on the mat under the smartphone. This may cause the charging plate to continue to discharge, which will not only damage your device, but may also melt foreign objects on the charging plate.

This is why it is important to look for a charger with a foreign body detector. It will turn off the charging and remind you—usually with an LED light—that something other than a compatible device is in contact with the charger. This will help prevent unsafe charging.

Overcharging

It's absolutely safe to leave your phone on the charging pad or mat overnight or for an extended amount of time because most charging pads will safely trickle charge your phone battery to keep it fully charged at all times.

When the battery drops below 100 percent while remaining on the pad, trickle charging occurs, and a little amount of current is delivered to the battery to maintain it fully charged at all times.

Overheating

There is no such charger that doesn't create some heat while charging a device. Every charger -- cable chargers, docks, portable power banks -- loses a certain amount of heat. Wireless chargers are no exception. They too create heat.

However, this heat doesn’t imply that the charger will get really hot. During the process of charging, wireless chargers, like other chargers, lose some energy in the form of heat. But it's important to choose a trusted manufacturer of wireless chargers to stay on the safe side. They pass wireless chargers through safety and efficiency testing that ensures that a minimum amount of energy is lost in the form of heat to bar the charger from getting hot.

Overvoltage

Intelligent microchips, sometimes known as smartchips, in chargers will only give the exact amount of power that your smartphone demands. While they may be capable of giving more power, this feature will only be enabled for phones and tablets that have a larger charging capacity.

Wireless Charging is The Future of Charging

Encapsulating Everything

Wireless charging has gained in popularity in recent times due to the convenience and efficiency it offers. It is the new normal that is quickly making its space at homes and offices. People are switching to wireless charging solutions to bring more ease to their lives.

If you haven't tried on a wireless charger yet, it is advised to go for a trusted manufacturer to buy a wireless charger.
