The charging read-only property of the BatteryManager interface is a Boolean value indicating whether or not the device's battery is currently being charged. When its value changes, the chargingchange event is fired.

If the battery is charging or the user agent is unable to report the battery status information, this value is true. Otherwise, it is false.
