Q: Can a MacBook Air charger  charge a MacBook  (white)?

The power available from the MagSafe adapter intended for a MacBook/Air

likely would be insufficient for a MacBook or MacBook/Pro. They vary due

to output specification, provide inadequate power and likely could be unsat-

isfactory in performance.

While you may be able to charge the battery in a MacBook whose original

adapter was higher output than a that from a MacBook Air, you may not

be able to run the MacBook from MB/Air adapter whilst charging its battery.

Other considerations should be followed, but general specification and well

intended design for correct power to the battery and computer needs have

to be met by the power adapter.

•Intel-Based Apple notebooks: Identifying the right power adapter and power cord

•Apple Portables: Troubleshooting MagSafe adapters

•Mac notebooks: All about batteries

You should try & match the correct spec adapter, or nearest. May be of higher

output than the one originally shipped with the notebook, but check all the spec

to make sure that, too, can be a workable match and not cause undue damage.

Depending on the build model identifier of the MacBook (these, made between

2006 and 2010) the power requirements changed; however a current working

replacement Magsafe 60w adapter is available from Apple, or quality vendor such

as OWC, see example: http://eshop.macsales.com/item/Apple/MC461LLA/

Hopefully this helps somewhat

Good luck & happy computing!
