USB Wireless Charger: What Is Wireless Charging?

By Johny Jacson


More and more mobile device users have turned to wireless chargers for their needs, and this is easily understandable. Since its inception as a small novelty device, the wireless charger has since then grew to carve out its own market niche.

Before joining the USB wireless charger craze, however, there are several things you have to know first about wireless charging. This article will discuss the principle behind wireless charging, the current industry standards when it comes to wireless chargers, and several other basic concepts.

Wireless chargers provide a means of transferring electrical energy without using the traditional physical wires. Also called inductive charging, it manages to do away with the traditional physical design by using a mat or the charger's surface to charge up your mobile devices.

The ease and simplicity with which you can charge is a big draw for many. If you remember multiple frustrating episodes of you scrambling to find your adaptor, cable, and phone socket in the dark, then perhaps trying wireless charging is the best way for you.

Since the device is more complicated, addressing these issues could also be more difficult as a consequence.

As for the current industry standards, here are two among the many: Qi and A4WP. Qi came earlier than A4WP, and its inductive system uses a lower frequency for power transfers. conversely, A4WP is the more recent of the two, and it uses a higher frequency for power transfers.

Third, another advantage of wireless chargers is that their structure is very compact. You can easily store such a device anywhere, and you will find it easy to fit it into your desk or shelf. The compact structure means is it more impervious to dirt as well, especially as compared to traditional wired chargers; the latter are more exposed to dirt.

Since you're going to look for one that's equipped with Qi technology, it'd be advantageous to pick one that comes with additional ports (such as the popular Vority Ki+4).

A USB wireless charger works as a flat transformer, and its shape allows it to be used with a very wide variety of items. The transformer has two sides: the primary side and the secondary side. The former is hooked to the energy source, and the latter will be inside the equipment which requires charging. The other parts include the two flat coils, as mentioned earlier, plus a pad or mat that will be linked directly to the device for charging.

However, they eventually became popular in industries outside mobile phones and tablets, even competing to harness the wireless charging technology. The point being: the pace with which it is being developed overtakes that of traditional wired charging technology. This simply means that you can expect even more developments and innovations on the wireless charging front.
