USB Wireless Charger: What Is Wireless Charging?

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.

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.

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.

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.

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

As for the current industry standards, here are two among the many: Qi and A4WP. Qi came earlier than A4WP, and its inductive system uses a lower frequency for power transfers. conversely, A4WP is the more recent of the two, and it uses a higher frequency for power transfers.

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.

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).

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.

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.
