45W one on a MB Pro), there won't be enough current to charge the battery, although you can run it off AC power while plugged in. In the reverse case, if you use too low a wattage adapter (e.g. Your MB Air will just draw the same amount of current whichever adapter is used, as long as the minimum wattage is provided. Some of the models require the higher current to charge their batteries, therefore those machines ship with higher wattage chargers. The voltage of these adapters is all the same (I think around 18.5volts? ), so it simply means the higher rated adapters are *capable* of providing higher current if necessary. See this KB article from Apple: the power rating of the adapter is simply the maximum power that it can supply. Here's the definitive answer: YES, you can use a higher rated power adapter with your MBA (or whatever) with no ill effect.

Suck it and see some mac are different to other - i would not suck it an see id get a 60W as you dont want find it kills your mac if you try it its at your own risk. Well i have an old MBP needing 85W that will NOT work with 60W i dont think that as mine is not backward compatible that the same mba - mac book air - of the same era would also not be compatable - it may work here n there temporarily but then damage the internal(s) of the machine as its designed to take less w-age - less wattage - NOT more or not 25W more then normal, however the only realy way to know is. (I know the 60w and 85w Magsafe power adapters have a different form factor and that the MacBook Air can't sit flat on a surface if you use them - I'm just curious if it's safe to use them on my MacBook Air.) Thanks! Just curious if anyone can definitively confirm that it is indeed safe. But I can't find any official statement from Apple confirming that this is so. I've seen internet postings on various sites saying that it's safe to use the 60w and 85w Magsafe power adapters with the MacBook Air (which comes with a 45w Magsafe power adapter).

RIGHT NOW JUST TRYING TO GET ANY KIND OF ELECTRICITY TO GO THROUGH IT AT ALL. NOTE: (not yelling) YES I KNOW THE NEXT STEP IS TO HAVE THE LOGIC BOARD PROFESSIONALLY CLEANED AND/OR REPAIRED BY A COMPONENT LEVEL REPAIR SHOP.
