Wireless Charging: How it Works and the Benefits

There are many accessories for mobile phones, from mobile phone screen protectors, mobile phone cases, to mobile phone wireless chargers, power banks. 

What if you could charge your devices without wires? This may sound like something from science fiction, but wireless charging technology has already reached the market and you can use it to recharge your phone or other devices as you move about the room. 

From the basics of how wireless charging works to its benefits, here’s what you need to know about this innovative technology that’s gaining traction.

General Overview

Here’s a quick overview. Wireless charging technology has been around for over 40 years, but it’s only recently that the tech has become small enough to be used in consumer electronics. 

What Is Wireless Charging?

Wireless charging is a method of powering electronic devices without the use of wires or cables. The most common form of wireless charging uses electromagnetic induction to transfer energy between two coils. 

How does wireless charging work? 

An inductive charger uses an electromagnetic field to transfer energy between two coils. When the primary coil is connected to an AC power source, it creates a magnetic field. 

The secondary coil, which is located inside the device being charged, picks up this magnetic field and converts it into electrical current, which charges the battery.

The Difference Between Inductive And Conductive Charging

Inductive charging uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging pad and a compatible device. Conductive charging, on the other hand, uses direct physical contact to transfer energy. 

The most common type of conductive charging is USB charging. The device is plugged into a power source, which then passes energy through wires and into the battery. 

Mention how inductive charging pads are powered by electricity or plugged into outlets. Point out that they can be plugged in anywhere in your home or office without having to take up any space on your desk or floor; many companies offer them as options for their employees’ desks or conference rooms. 

Add that inductive chargers work best when there’s little interference from metal objects like coins, keys, jewelry and cell phones – which you would need to remove before placing your phone onto the charger pad so that these items don’t interfere with the electromagnetic field generated by inductive chargers – though some models have more than one coil to ensure compatibility.

Advantages of Wireless Chargers

The chief advantages of wireless chargers are that they’re much more convenient than wired chargers—you don’t have to fumble around with cables in the dark, and you can use your phone while it’s charging. They’re also great for public places like coffee shops, where people are constantly coming and going. 

Wireless chargers are also becoming increasingly affordable, making them a great option for budget-minded consumers. Finally, wireless charging is becoming more widespread, so it’s likely that your phone will be compatible with a wireless charger even if it wasn’t when you first bought it.

How to Choose Wireless Chargers

When choosing a wireless charger, you’ll want to consider a few factors such as price, compatibility, convenience, and design. 

First, check to see if your device is compatible with Qi wireless charging. 

Most newer smartphones are compatible with Qi, but there are a few holdouts like the iPhone. If you have an iPhone, you’ll need to get a wireless charger that’s compatible with Apple’s proprietary system. 

Second, think about how convenient you want your wireless charger to be. 

Do you want something that you can just drop your phone on and walk away, or do you want something that’s more hands-on? 

Third, consider the price. Wireless chargers range from around $10 to $100 or more.
