+Description:
+		Identical to charge_type but reading returns a list of supported
+		charge-types with the currently active type surrounded by square
+		brackets, e.g.: "Fast [Standard] Long_Life".
+
+		power_supply class devices may support both charge_type and
+		charge_types for backward compatibility. In this case both will
+		always have the same active value and the active value can be
+		changed by writing either property.
+
+		Note charge-types which contain a space such as "Long Life" will
+		have the space replaced by a '_' resulting in e.g. "Long_Life".
+		When writing charge-types both variants are accepted.
