Advantages: USB Wireless 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.

Second, another disadvantage is that wireless chargers generally come at an extra cost. Naturally, these are the most recent innovations in the industry, which makes them pricier than traditional models. This is, of course, understandable, and many are willing to pay for the better technology anyway. Still, keep in mind that you must look for a charger that is reasonably priced-do not just fork over cash thinking the expensiveness is automatically justified just because it is wireless. Price does not always equal quality.

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.

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.

This will no longer be a concern with a USB wireless charger. Some wireless chargers have their own physical wires, but the best ones, like the Vority Ki+4, have built-in AC adapters.

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.

However, it also means that wireless chargers are still being perfected, and that you can expect even better performance from wireless chargers in the years to come.

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.
