The voltage required to charge that battery from the DC input on the laptop might be more than twice the battery voltage. Unless you want to remove the battery to charge it, look at the DC OUTPUT of your AC adapter. That will have to match when you charge the laptop.My white MacBook has a 10.8V battery. My 2010 MacBook Pro has an internal battery, but both machines use the same Apple Magsafe Charger. It's a good bet that the MacBook Air also has a 10.8V battery.
There's a small switching power supply inside the Apple power brick, and as I say, it prolly deals fine with inverter input. The big problem with the damn thing is the output cord. The strain relief does not do a proper job. YouTube is loaded with videos about how to fix the cable. Most start with a dremel tool. The thing was not designed to be serviced.
Or look to see if the input voltage is mentioned on the laptop itself.
