+               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.
