New Charger - What Wattage?

[player1146]

My sister just got a MacBook Air (Mid-2011) with the Model number A1370 EMC 2471.

From the pictures she sent me, there's no indication of the wattage your charger should have.

When I google the model number + "charger" it lists chargers of different wattages.

What wattage of laptop charger should this MacBook use?
