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.

The biggest selling point of a wireless charger, and also its first advantage, is convenience. It is easy to carry and store, and it is ideal for use during travels. It is also extremely easy to use. You do not have to fumble for charger sockets and wires anymore. You simply have the plug the charger itself and then place your device on top of it. Induction-a basic principle in energy-will do the rest.

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).

Fourth, another advantage of the USB wireless charger is that the technology it uses is constantly being developed. It is worth noting again that wireless chargers have their origins as novelty devices. They were developed for a specific niche.

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.
