Compatible MacBook Air models

This 45W MagSafe 1 AC adapter fits MacBook Air 11-inch models from 2008 to 2011 and 13-inch models from 2010 to 2011. It matches Apple part numbers A1237, A1244, A1304, A1369, A1370 and A1374. The charger is supplied new and ready for use.

Input and output ratings

The unit accepts 100-240V at 50/60 Hz and delivers 14.5V at 3.1A. These figures match the original specification for the listed MacBook Air models. No other voltage or current ratings are provided.

MagSafe 1 connector constraint

The adapter uses the original MagSafe 1 connector, so it will not fit MacBook models that require the MagSafe 2 or USB-C interfaces introduced after 2012. Buyers with later MacBook Air or MacBook Pro models must choose a different charger.

Questions about this item

Will the 45W MagSafe 1 adapter power my 2010 13-inch MacBook Air without damaging the original battery?

Yes, the 14.5V 3.1A output matches Apple parts A1237 A1244 A1304 A1369 A1370 A1374 used in 2008-2011 MacBook Air models, so it charges the lithium-ion battery exactly as the original supply did.

How can I confirm the charger is delivering the correct 14.5V 3.1A to my MacBook Air after plugging it in?

The MagSafe connector LED shows amber while charging and green when full; macOS System Report under Power lists the adapter as 45W with 14.5V output, confirming correct operation.

Does the box include the AC wall cord or only the 45W MagSafe 1 brick with fixed cable?

The package contains the 45W MagSafe 1 adapter with its attached output cable; the detachable AC wall cord (duckhead) for 100-240V 50/60 Hz input is not included and must be sourced separately.
