    • wireless charging are the new revolution in the technological world.
    • however have an obstacle to overcome: they are slower than the standard charger.

    wireless Charging Qi

    wireless charging are the revolution of the moment. Present in Android since a few years ago, they were still by be extended to other types and ranges of devices.

    however, with the launch of the iPhone X, 8 and 8 Plus, Apple has taken the opportunity to announce that these devices will also be compatible with the load without cable. And suddenly, what until recently was passing by unnoticed, now charges great importance (though for many users it still remains a mystery).

    How is it possible to transmit energy to a mobile device without a cable? As explained in Computerhoy.

    Transforming energy: device-electromagnetic field-device

    Although these new devices they call “wireless charging”, load directly to a mobile without the need of any external peripherals is, today, impossible, wireless charging always requires a basis consistent with the same. Normally, this base does not come included with the phone once you buy, so you have to buy it separately.

    This base acts as a transformer. The power comes to it via a cable and then transfers it to the mobile through an electromagnetic field in the form of waves. The key part of all of this is the induction coil which is present in both the base and the mobile phone: that is really where it transfers and transforms energy.

    The downside of these chargers wireless is speed, since having to transform two times the energy, the speed of load is reduced in the mobile. So if you have a hurry, charge your mobile, it will be better to rely on a charger that is conventional.

    This process of loading is completely secure while it’s always recommended that you charge your mobile with a base of trusted brand.

    Types of wireless charging

    in Addition to the type of load resonance, there is also another type of charge known as electromagnetic load inductive.

    In the beginning, this type of load had several competitors: the Wireless Power Consortium on the one hand, and Power Matters Alliance on the other. Finally, the two brands decided to join the patent and was born Qi, the interface, which today support most mobile, such as the Samsung Galaxy S8 or Iphone X.

    This type of inductive load is much more secure that the resonance as it needs the mobile and its base are in contact, which reduces the risk of calambrazos. Its advantage is that as the load resonance reaches a maximum of 7 V, the inductive load provides 15 V.

    however, and although the development of these loaders is in constant evolution, still have a meta get: the quick charge. Is now available to cable and, at least in some way, also without him. However, we must be careful to qualify to “fast charge” to the wireless, as for how fast it is still slower than the wired.
