Qi (pronounced /tʃiː/ CHEE;[1] from simplified Chinese: 气; traditional Chinese: 氣; pinyin: qì) is an interface standard for wireless power transfer using inductive charging. The standard allows compatible devices, such as smartphones, to charge their batteries when placed on a Qi charging pad, which can be effective over distances up to 4 cm (1.6 in).[2]
The Qi standard is developed by the Wireless Power Consortium.[1] As a universal, open standard Qi-enabled devices are able to connect to Qi chargers from any manufacturer.
Qi was first released in 2008; by 2017, it was incorporated into more than 200 smartphones, tablets and other devices.[3] As of December 2023[update], there are 351 manufacturers working with the standard including Apple, Asus, Google, Huawei, LG Electronics, Samsung, Xiaomi, and Sony.[4]
In January 2023, the consortium announced Qi2, which will update the existing standard and include a magnetic connection based on Apple's MagSafe technology.[5] On April 19, 2023, Wireless Power Consortium released the Qi2 standard.[6]
