New Qi2 wireless charging standard unveiled, based on Apple's MagSafe. Best wireless charging
5Somebody check up hell has frozen, because iPhones are getting USB-C ports while Android is officially getting MagSafe... sort of!
The WPC (Wireless Power Consortium), the body behind the Qi wireless charging standard, has unveiled a second revision that hopes to bring all the current major wireless standards under one umbrella. As per the WPC, Qi2 is expected to be introduced later this year, with Qi2 chargers and phones reportedly expected just in time for the 2023 Holiday shopping craze.
"Consumers and retailers have been telling us they’re confused concerning what devices are Qi Certified and those that claim to work with Qi but are not Qi Certified. This confusion can lead to a poor user experience and even safety issues," announced Paul Struhsaker, executive director of the Wireless Power Consortium, in a press release. “Our standard assures consumers that their devices are safe, efficient, and interoperable with other brands. Qi2 will be the global standard for wireless charging and provide consumers and retailers with that assurance.”
Dubbed Qi2 and pronounced "chee two", the new standard is built around Apple's MagSafe wireless charging solution, which utilizes magnets to make sure the charging coils are. always aligned perfectly. Conversely, Qi2 scores the so-called Magnetic Power Profile, which basically utilizes the magic of magnets to make sure your phone never moves away a few millimeters to the side, thus interrupting the charging process. This would also cut down energy loss in our current world where energy efficiency is under the utmost scrutiny.
Though numbers aren't mentioned, Qi2 also promises faster wireless charging "for some devices", but also lays the groundworks for even faster Qi-certified wireless charging solutions in the future.
“Energy efficiency and sustainability are on everyone’s minds these days,” Paul Struhsaker also revealed. “Qi2’s perfect alignment improves energy efficiency by reducing the energy loss that can happen when the phone or the charger is not aligned. Just as important, Qi2 will greatly reduce the landfill waste associated with wired charger replacement due to plugs breaking and the stress placed on cords from daily connecting and disconnecting.”
Does Qi2 mean that you will be able to charge your future Android phone with a MagSafe charger, or vice versa? Given that you can currently charge an iPhone with any Qi-enabled wireless charger, and use your MagSafe charger to top up Android devices even though it wouldn't snap in place, we are mostly certain that there will be much greater interoperability and flexibility in the wireless charging space than before.
The first iteration of the Qi inductive wireless standard was introduced back in 2008, and after a brief scuffle with Power Matter Alliance's competing PMA standard, became the de facto go-to standard for wireless charging as it garnered better industry and consumer support, but probably the most important reason was Apple joining the WPC and backing up the Qi standard. The main differences with PMA were the wavelength that were utilized for the inductive charging (100-205kHz for Qi, 277-357kHz for PMA), otherwise the two solutions were pretty much similar in how they function.
