USB Wireless Charger: What Is Wireless Charging?

By Johny Jacson


Ask around and you will discover that the wireless USB charger is very nearly a staple for all mobile device users, regardless of whether they are always on the go or not. Primarily, this is due to the high level of convenience that wireless chargers provide. However, as in all devices, wireless chargers also have their set of cons, which will be discussed in this article.

First, most wireless chargers are physically lightweight. While it is true that this provides convenience, it can also be easily worn and damaged. That is one tradeoff that you would have to make when buying a wireless USB charger. The key here, then, is to find a brand and a model that will provide you both perks of light structure and durability, like the Vority Ki+4, the first combined 4-usb-port and wireless charger.

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.

Because of this, wireless chargers are in vogue among many users of portable devices like smartphones and tablets. Aside from prevalent use among mobile phone users, wireless chargers have also been tapped for use with other cordless devices when the use of traditional charging methods is impossible or counterproductive.

Second, and in relation to the first one, the extremely simple method of charging means you get to do away with cables. It reduces the damage to plugs and sockets as well. Many phone users complain how quickly charger cables and connectors get damaged today.

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.

However, keep in mind that for their light structure and their advanced and convenient technology, the issue regarding lessened efficiency is easily compensated.

The important thing to highlight here is that wireless chargers are still part of a developing technology. One cannot expect the same stability of performance that comes with the traditional wired chargers. Some see this as a disadvantage, because it means that the technology could be unreliable at times.

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.

The few pieces of information tackled here are important not only to help you understand your wireless charger. These are also important because these can help give you an idea on how to maintain and take care of your wireless charger. Keep in mind however, that this is just a basic guide of sorts. You can easily find other relevant information online, or from your nearest local supplier of wireless chargers.
