Charging Macbook on Qantas A380

So I'm going from Melbourne to LA tomorrow, and I'm planning to use my Macbook on the flight. There is a power source on the plane, and I was wondering if I can charge my Mac using this power. It says on their website that the "system provides 110V AC (60 Hz) power" and "the PC power is configured to provide a maximum of output of 75 watts." Will this be suitable for my Macbook (2009 white model)?
