Does anyone know if I can safely use an MBA 13" power brick on an MBA 11" system? I recently took advantage of the Best Buy sale (actually the Amazon price match on the Best Buy sale) to purchase an MBA 11". I have several power cords laying around for my old MBA 13" (2010 model) and am thinking of buying the Magsafe converter to use the old(er) power cords for the new MBA 11".

Will this adversely affect my new MBA 11"?

I'm using an old 13" MBP Magsafe with the converter for my 11" Air right now.

No problems.

I think issues arise when you try to use the smaller ones for the bigger computers, or something like the HUGE 17" brick for the little guys, but I can't confirm that.

Anyway, my 13" MBP brick, which is larger than the one that came with the 11" Air, works fine.

Yes, they should work fine. I believe the chargers are actually identical for the 13" and 11" models. In any case, you can use a more powerful charger than the one your Mac is designed for. It will draw only the level of power that it needs. The bigger issue is if you try to use a charger from a MacBook Air with a MacBook Pro (or a 13" Pro charger in a 15", etc.). In that case, it's possible that the charger won't be able to keep up with the power demands of the Mac and still charge the battery.

I've used my 15" MBP charger (same as the 17") with my wife's 11" MBA with no problems. I haven't tried the other way around, but I expect it would be able to charge the battery (slowly) but not keep it charged when in use.

Thanks all! I figured as much, but wanted to get feedback from the community.
