+\subsection{Accessory Power Supply}
+This option turns the accessory power supply \setting{On} and \setting{Off}.
+The Apple accessory protocol has been partially implemented in Rockbox, and
+thus there is a reasonable chance that your favourite accessory will work.
+The accessory may require power from the \dap{} to function, and if so you should turn
+this option \setting{On}. If it is not required, then turning this setting
+\setting{Off} will save battery and therefore result in better runtime.
