Features and specifications
With Qi version 2.0, WPC introduced Magnetic Power Profile (MPP), an optional part of the specification based on Apple's MagSafe for iPhone. This enables magnetic attachment and alignment with a ring of permanent magnets around the charging coil and is backwards compatible with MagSafe devices. Devices that implement MPP use a new logo and branding, Qi2 in a circle, to distinguish them from Qi devices that do not support MPP (even if they otherwise support Qi v2.0 or later). The "Qi2 in a circle" logo has previously been sporadically used for Qi2 without MPP, this usage is officially disapproved for new products. Previously Qi(1) products are to be labeled as Qi2, as use of the Qi(1) logo has been discontinued.
