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.

The biggest selling point of a wireless charger, and also its first advantage, is convenience. It is easy to carry and store, and it is ideal for use during travels. It is also extremely easy to use. You do not have to fumble for charger sockets and wires anymore. You simply have the plug the charger itself and then place your device on top of it. Induction-a basic principle in energy-will do the rest.

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.

Wireless chargers operate by using a magnetic or inductive field in between two coils, through which the electricity is transferred. Once transmitted through the coils, the energy winds up in the receiver and this will start charging your device's battery.

Fourth, another disadvantage is that some tradeoffs have to be made in relation to efficiency. While efficiency levels of 85-90% on average could be achieved by wireless chargers, there could be resistive losses on the coils or losses induced by stray couplings, among others issues.

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).

Fourth, another advantage of the USB wireless charger is that the technology it uses is constantly being developed. It is worth noting again that wireless chargers have their origins as novelty devices. They were developed for a specific niche.

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.
