 Description:
 		Represents the type of charging currently being applied to the
-		battery.
+		battery. "Trickle", "Fast", and "Standard" all mean different
+		charging speeds. "Adaptive" means that the charger uses some
+		algorithm to adjust the charge rate dynamically, without
+		any user configuration required. "Custom" means that the charger
+		uses the charge_control_* properties as configuration for some
+		different algorithm.
