Advantages: USB Wireless Charger

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.

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.

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.

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

Comparatively, and in keeping with the same principle, wireless chargers are safer for use in contaminated areas. As a consequence, it is ideal for use in medical settings and for medical equipment that require wireless charging.

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.

Remember that any piece of technology have its disadvantages. No piece of tech is perfect. The key here is to be aware of these disadvantages and spend enough time to search for specific models that can offset these. This will make sure you make the most out of your wireless USB charger.
