Expert technical article "How to ensure the safety of Qi® wireless charging?" 》

Over the past few years, the Wireless Power Consortium (WPC) has been busy updating the widely adopted Qi® standard in a variety of ways. Of course, as the world becomes more interconnected, the safety of wireless charging will always be a top concern. Version 1.3 of the Qi wireless charging specification adds secure authentication capabilities.

Version 1.3 allows Qi-enabled devices to verify the charger's identity and its compliance with the Qi specification. This determines whether the charger is compatible with the Qi standard to ensure it does not damage or destroy the product it is charging. It's essentially an extension of Qi version 1.2, but adds a layer of protection (authentication) to ensure the phone and charger can work together. Qi 1.3 defines two power configurations. The base power configuration can provide an output of up to 5W, while the extended power configuration can increase the output to 15W.
