From Wikipedia
Qi ( CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium. It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). Devices that implement the optional Magnetic Power Profile, based on Apple's MagSafe wireless charging technology, using magnets for better device attachment and alignment to a charger may be labelled Qi2. Qi version 1.0 was released in 2010; by 2017, it had been incorporated into more than 200 models of smartphones, tablets, and other devices. In December 2023, 351 manufacturers were working with the standard, including Apple, Asus, Google, Huawei, LG Electronics, Samsung, Xiaomi, and Sony. The Qi specification version 2.2, released in April 2025, supports charging speeds of up to 25 watts and aims to improve compatibility across devices from various manufacturers. The current version 2.2.1 released in July 2025 includes Qi2 25 W branding for the 25-watt charging mode.
