For wireless charging products, the magnetic design will become the best design at this stage.
In September 2020, when Apple announced the design of the back magnetic wireless charger named "Magsafe" at the launch of the iPhone 12 series, the first reaction of many people and our LANTAISI, was undoubtedly all are "Apple has opened a new accessory market."
Whether it is from the many Magsafe accessories displayed by Apple at the press conference or from our own evaluation experience, the iPhone 12 series has indeed greatly improved the loading and unloading accessories (such as protective shells) after adding the magnetic back design. ) Time experience. However, because of this, we have overlooked a key message.
In addition to the attractiveness of the back magnetic wireless charging, does it really have practical value in a technical sense? The answer is yes, not only that, but also professional tests:
We have designed three charging scenarios. The first is ordinary wired charging, the second is to carefully place the mobile phone in the center of the wireless charger for wireless charging, and the last is to "set it away" to make the mobile phone slanted in the center. Wireless charging is performed on the wireless charging base.
The results show that for wireless chargers and mobile phones without magnetic structure, even if the mobile phone and wireless charger are carefully aligned with the coil position, the conversion process of electricity-magnetism-magnetism-electricity still makes wireless charging better than wired charging. 39% more electricity is consumed. Since this part of the electric energy is not actually charged into the battery of the mobile phone, it is equivalent to pure wasted.
However, this is not the most scary. Because the experimental results show that even if the wireless charging coil inside the mobile phone is not aligned with the coil position of the wireless charger a little bit, this kind of energy waste will suddenly increase. So to what extent will it increase, it is almost 180% of wired charging!
Nevertheless, the problem is that for a wireless charger without a magnetic structure, no matter how the shape of the charger is used to guide the user to "righten", it is actually difficult to accurately position the charging coil every time.
Not only that, but friends who have used this kind of non-magnetic wireless charger know very well that although wireless charging looks convenient on the surface, in fact, in order to maintain the charging state, the mobile phone must always be placed on the charger. This also means that if you are using the kind of large wireless charging base on which the phone is placed, you can say goodbye to the "charging and playing" experience.
However, if you add a back magnetic wireless charging structure to your mobile phone, then the two major problems mentioned in the previous article can be solved instantly. On the one hand, the coil alignment problem between the mobile phone and the wireless charger can be solved directly with the help of the magnetic structure, without the user needing to carefully adjust the placement position, as long as one "suck", 100% coil alignment can be naturally completed, thereby reducing Energy waste, and effectively accelerate the speed of wireless charging.
On the other hand, as demonstrated by the previous iPhone 12 series and the new realme machine exposed this time, for the magnetic-attracted wireless charger, because the coil can be very accurate, the volume of the coil can also be made. It is very small, so it can be connected to the power supply and the charger through a long cable to realize high-speed wireless charging through the small charger attached to the back while playing games, which perfectly solves the problem of the traditional large wireless charging base that cannot "play while charging ".
