Disadvantages: Wireless USB Charger

By Johny Jacson


The USB wireless charger is now enjoying well-deserved mainstream popularity, thanks primarily to its convenience. Wireless chargers only begun as a novelty innovation, but now they have carved a niche in the market. They are even being used for other applications aside from those that involve mobile phones and similar devices.

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.

Third, another disadvantage to using a wireless USB charger is the added complexity of the system. Obviously, a wireless charger's system will be more complicated than that of a traditional wired charger. While this could be seen as a good technological leap, there is a tradeoff in the sense that some maintenance issues could also come up.

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

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.

Unlike the Qi, A4WP allows you to charge multiple devices all at the same time, which is a big improvement over the former. Do take note however, that A4WP is still experimental, meaning you won't be able to buy a charger that uses it.

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.

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.
