Wireless Charging Technology: Better Choice for Phone charging?

Nowadays, wireless charging is becoming more and more common. You can buy phones with wireless charging coils inside them, purchase wireless charging mats from tech stores, and businesses like Starbucks are beginning to roll out wireless chargers. There will be no worry about changing your cables, breaking the port of your phone, or troubled by a twining cable. Without any annoying and fragile USB cables, you can simply charge your mobile phone while working.

Why is the technology so cool and powerful? Unite Cable Enterprise Co., Ltd will have a how it works and why it is so popular. 

      What Is Wireless Charging?

Wireless charging (also known as "inductive charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electric current to charge the battery. The two induction coils in proximity combine to form an electrical transformer. 

      Different Competing Standards

“The great thing about standards is that there are so many of them to choose from.” – Grace Murray Hopper

As the saying goes, the development of wireless charging is also diversified. That’s because there’s one problem: The companies involved haven’t settled on a single standard for wireless charging.

The standards are designed to ensure that devices and wireless chargers from different companies can work together. There are three standards: Qi, PMA (Power Matter Alliance),

Powermat, and A4WP (Alliance for Wireless Power).

While current devices overwhelmingly use the Qi standard, it looks like the PMA standard may be the most popular one in the future — which means that current devices may be incompatible with most wireless chargers in the future. It’s also possible that another standard may take over.

Smartphones That Support the Technology

However, that’s not a kind of technology that can be enjoyed as long as you download a certain App or something else. That’s to say, not all smartphones support that cool function. To use wireless charging, of cause you’ll both need a smartphone that supports wireless charging and a wireless charging mat to place the device on.

Popular smartphones that support wireless charging:

       * Nokia Lumia 920

       * Nokia Lumia 820

       * Google Nexus 4

       * Samsung Galaxy S4: You’ll need  an official “wireless charging cover” that replaces the Galaxy S4’s back panel.

       * HTC Droid DNA: Other HTC phones, like the new HTC One, do not have wireless charging support.

       * Apple iPhone 5: Wireless charging is not included in the iPhone 5, but you can buy a Power mat case that adds wireless charging capability to your iPhone.

All of the above smartphones use the Qi standard, except from the Apple iPhone 5 case made by Powermat, which uses Powermat’s own standard.

You need to be careful when purchasing a wireless charger mat to ensure it works with your smartphone. While wireless chargers are supposed to work with all certified smartphones supporting the standard — a Nexus 4, which uses the Qi standard, is supposed to work with all Qi chargers — some users have been dismayed to find that their Nexus 4 doesn’t work with certain Qi chargers.

It appears the standards still have some kinks to work out. As for the technology, there is still a long way to go. Also, after a series of survey, Unite Cable Enterprise Co., Ltd has found that wireless charging has its demerits as well as attractions, as every coin has its two sides. So, will wireless charging take the place of wired charging in the future? The answer is, undoubtedly, NO.
