Hi everybody.

Is there a difference between the Apple chargers. I mean the white block ones that get smaller all the time. First Apple made them bigger but as time passed Apple reached to make them smaller. But does their voltage change?

It depends on the output power, all mag-safe voltages remain the same as do the USB chargers.

Uh, do you realize what you just said???

Yes, there are differences between the power adapters.
There are 40W, 60W and 85W power adapters available for the Air, Macbook and Macbook Pros respectively.

An 85W power adapter will work on the air (if you plug in on a slant), or the Macbook.

The 60W will let the Macbook Pro run, but not charge the battery or fully charge the Air.

The 40W will let the Macbook run, will work perfectly on the Air, and will not power a Macbook Pro.

Yes, these adapters have shrunk in physical size and weight, but they are still identical in function.

Ok. Thank you but also what about iPod chargers?

iPod chargers? they are probably the same unless they specify that some ipod (such as the new shuffle?) may use a different charger

( If i'm correct the new shuffle charges thru the headphone jack)
