Wireless charging is already around for some time now but even so, it’s not as widely spread as one would expect. Some say that it is a normal thing considering that we’re talking about fresh technology that still needs a lot of pushing towards customers. Also, things are about to change since the new iPhone X is seen as a perfect opportunity to properly promote wireless charging. But what is wireless charging and how does it work?
Pretty straight-forward as the name speaks for itself, charging the phone wirelessly is being able to replenish your battery without connecting it to a socket through a charger and cable. Some models of phones that allow wireless charging to have a built-in pad that interacts with the pad that transmits power and some of them deliver it separately and it needs to be connected before charging.
How does it work?
The principle behind wireless charging is inductive charging or the flow of electricity through coils to generate an electromagnetic field between them. When the magnetic plate that built-in the phone gets in the specified range, the magnetic field generated between the coils has electrical current as a biproduct. This generated current is converted inside the phone to direct current that fuels the battery.
Wireless Charging Standards
At the moment there are a few standards when it comes to wireless charging. As mentioned above, as the technology will become more and more popular, the number of these standards will increase, and we will have the same diversity as with everything connected to gadgets and smartphones. The most-used one is QI and it was developed the inductive charging method for distances of 40 mm. Qi functions with three power specifications:
- Low Power – up to 5W – mostly used for charging smartwatches or other mobile devices
- Medium Power – goes up to 120W – and it is perfect for your laptop on which you can check for top rated online casinos
- High Power – 1kW – that can power other, more powerful electronic devices in your home
The Qi standard for wireless charging was already implemented by a lot of international phone manufacturers like Samsung, LG, HTC, Sony, Huawei, Blackberry or Motorola.
The other standard for charging wirelessly is PMA. It’s also about inductive charging, however, they closed a deal with the A$WP to start developing some magnetic resonance charging methods instead. So far, there was no announcement regarding a new method being developed.
What phones work with wireless charging?
Currently, there are a lot of phones that already can be charged wirelessly. The Samsung S6, S6 Edge and Blackberry Priv are phones that support both the PMA and Qi standards with the technology built into their framework. A lot of models from the above-mentioned producers will work just fine with wireless technology, however, if your model is not compatible, there’s no reason to worry. You can simply attach an adapter or a special case that will make it compatible with Qi charging. Simple and efficient!
