I'm baffled about if it is possible to use a 60watt apple charger for a Macbook Air 11 mid 2011 without any harm to the Air or battery.
Quote from below linked article from Apple.
"Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. Although you should always use the proper wattage adapter for your Apple notebook, you can use an adapter of a higher wattage without issue."
