There are different ways to charge wirelessly. Essentially they all start from the same basic idea of using induction coils to transfer energy, but in their practical form, they have different materializations. Among all this, the Qi standard emerges.
It is the standard that governs the vast majority of bases and devices we charge wirelessly. A standard developed by the Wireless Power Consortium (WPC) of which, among others, Apple is a member. A standard that will soon be much more versatile and precise.
The importance of the magnetic system at the heart of the new standard
During CES 2023 taking place in Las Vegas, the WPC announced the new Qi2 standard which was developed with the help of Apple. This new standard it will improve the reliability and above all the efficiency of the current system thanks to a new feature: the Magnetic Power Profile. In other words, thanks to MagSafe.
Since its presentation with the iPhone 12, the grace of the MagSafe system has been the precise alignment of our devices with the charging base. An alignment that was supported by magnets and that guaranteed the maximum possible efficiency because the coils were perfectly superimposed. Thanks to this, with MagSafe we can reach charging speeds that the Qi system does not always allow.
The new Qi2 standard was developed in collaboration with Apple, so it will be fully compatible with MagSafe. A MagSafe which is currently an Apple proprietary standard and will soon reach other brands and devices without royalty fee. Good news, no doubt, because in addition to improving wireless charging for all devices in general, from the point of view of an Apple user, we will have a much wider range of accessories and solutions to choose from
With the presentation, still awaiting official launch, of the new version of the Qi standard now at CES in Las Vegas, it is to be expected that let’s start seeing the first compatible devices before the end of the year. According to the WPC, more than one billion Qi devices will be sold in 2023, so the new standard is expected to quickly change the outlook for wireless charging around the world.
