Charging our gadgets is a necessary part of life, but the ugly charging wires, scurrying to find a charger, and aggravation that comes with neglecting to plug in your phone are all things we could do without.
Wireless charging is a method that transfers power between a battery or other gadget and a charger by using magnetic fields.
Inductive charging is the most prevalent method of wireless charging. The power transmitter and receiver are built into the same unit in inductive charging, which is commonly attached to or located near the charged device.
Inductive chargers emit a magnetic field, which generates a current in the receiving device. This current is responsible for charging the battery or powering the device. Wireless chargers exist in various shapes and sizes, but they all work on the same premise.
What’s Fueling The Demand?
Wireless charging using a wireless charging pad can alleviate all of this. As the future of charging signs progress, the latest smart devices will no longer require a little wire to be plugged in.
Wireless chargers come in a variety of styles and sizes. It’s convenient, quick, and simple to use. Simply place your phone on a wireless charger, and it will begin charging as soon as it comes into contact with the surface.
Both Android phones and iPhones may absorb a charge by just setting them on a specific mat, also known as a “charger pad” or “charging surface.”
Wireless charging may even be achievable simply by being close to a charger, eliminating the need to pull your device out of your pocket to charge it.
However, the technology isn’t quite there yet. A University of Warwick study discovered that charging phones through induction could shorten their battery’s lifespan.
The researchers said that wireless charging necessitates energy transmission through an air gap, which generates heat. Because the phone’s and charging pad’s surfaces must be in such proximity, the heat exposure will shorten the phone’s lithium-ion battery life over time, as they are susceptible to temperatures exceeding 30 degrees Celsius.
Misalignment, i.e., when the coils in the device and the charging station are not directly on top of one another, exacerbates the existing problem; the charger boosts the transmitter power to adapt, resulting in even more heat and possibly battery damage.
It’s difficult to escape this trap because the coils’ locations are rarely made clear. As the researchers conclude, the latest evidence suggests that consumers must decide whether the simplicity of wireless charging is worth lowering the lifespan of their smartphone.
What is Wireless Charging, and How Does It Work?
Wireless charging entails picking up the phone and placing it on a charging dock without the need for a wire to be plugged into a device.
Wireless charging isn’t truly cordless because the charger still needs to be plugged into a power outlet. A wireless charger is typically in the form of a stand, mat, or pad. Qi, pronounced “Chi,” is the most commonly utilized wireless charging method today. This standard is used in various devices, including the Samsung Galaxy, iPhone, and others.
Are Wireless Chargers Safe to Use?
Wireless charging, contrary to popular assumptions, is completely safe to use. It will not harm your smartphone’s battery because it carefully manages the procedure.
Undoubtedly, wireless phone chargers create electric and magnetic field radiation, although only to a limited extent. Wireless chargers will not endanger human health in their current condition.
Advantages of Wireless Charging
It’s difficult to argue against the ease of having a wireless charger. After all, wireless charging has brought about numerous positive developments by alleviating several issues and inefficiencies caused by cable charging. The following are some of the most notable benefits of using a wireless charger:
-
Hassle-Free
If you’ve ever spent 5 minutes untangling a tangle of wires and cords, you understand the allure of wireless charging. The first benefit that immediately springs to mind is that you’ll never have to deal with irritating cables again.
Consider the convenience of not having to plug and unhook the cord when users need to charge your phone. They have to charge it and then pick it up when you’re ready to leave.
-
Charge Multiple Devices At Once
A few wires are all it takes to make your table look sloppy, but five or more wires are a recipe for disaster. Another obvious advantage of wireless charging is that most wireless chargers can charge many devices simultaneously.
If more than a few devices have low batteries, place the phone, watch, or wireless earphones on the wireless charger and allow the electricity to flow.
-
Portability
A wireless portable charger is a miracle for individuals who are constantly on the road. In addition to charging wirelessly at home or work, they can charge while on the road to stay productive. Attach the wireless charger to the back of your phone to give it a power boost with no other attachments necessary.
-
Wear and Tear
Many cables break quickly and deteriorate, leading to buying replacements for these sub-standard parts. There’s no worry about changing wires every six months with wireless phone chargers.
-
Aesthetic
Many users prefer wireless chargers due to their aesthetic appeal. Many of the new wireless charging devices are very sleek in design and can be easily put in any location near a power outlet inconspicuously.
Future Trends
The major players in the market are moving to capitalize on the demand in the global market by offering a diverse product offering.
For instance, Dell’s new laptop dock includes a Qi wireless charging stand that allows you to see and charge the phone while connecting the laptop to monitors and accessories.
The Dual Charge Dock can power PC with 90W via USB-C and phones with 12W via the fabric-covered wireless charger.
Dell claims in a press release that the charging coils in the Qi portion of the dock are widely spaced, which means you can charge your phone when it’s in portrait or landscape mode, and you can even use the charger to charge a set of wireless headphones.
