All Rights Reserved. 631 70. Apple MagSafe Charger Module 70.4 Charging Status 70.4 Charging Status To monitor charging status, accessories may use the HID report with ID 0xA1 on interface 2, consisting of HID Vendor Page (0xFF00) Usage ID 0x0011, a uint8 value representing the following charging states:
0 - Empty. 1 - Charging up to 5 W. 2 - Charging up to 7.5 W. 3 - Charging up to 15 W. The charging status report is sent once per second and can be used to determine if the module is powered. Accessories may indicate to the user when the module is powered and its charging state, using an LED or other means. For example, a multi-color LED may use green to indicate the charger is powered and other color(s) to indicate the charging state when a device is present. 70.5 Controlling Power in 9 V Mode Available power to the MagSafe Charger Module may be adjusted dynamically when using an Internal Power Supply (page 629) in 9 V PowerMode (page 635). To configure the available power, the host may send a HID report with ID 0xA0 on interface 1, consisting of HID Vendor Page (0xFF00) Usage ID 0x0046, a uint8 value for the available power in W. Charging may be disabled at any time by setting the available power to '0'. The minimum value required to enable inductive charging is 12 W. When the Charging Status (page 632) is:
'0' or '3', the value may be dynamically adjusted. 1 or 2, values are not dynamically adjustable. Charging has to be stopped before setting a new available power value. 70.6 Firmware Update Over USB MagSafe Charger Module supports firmware updates over USB-C from Mac computers.
