Can you use a macbook air charger on the macbook pro? our pro charger snapped today
Yes, but it will charge slower and during CPU intensive tasks, the battery will be drained, as the MBA charger does not have enough power.

I had a look on the Apple site and people have suggested that you can use the higher wattage (85 W) of the MacBook Pro charger on a MBA, but not the other way around.
Personally I would not want to take the risk either way.
This thread just made me realize that I don't have the right wattage. I have 2 and both are 60w. They have been okay but charging to full takes about 3 hours. I have AC, I wonder if this is an issue.
ur macbook pro ddid not come with a charger? LOLLOL
although you would not, doesnt mean you couldnt right? you could but it would charge slow or not charge at all(when turned on)?
i think it will charge when its shut down though.
Yes, you can, but it will take longer to charge.
Even for my MacBook Air, I buy the 85W adapter. Sure it's bigger, it works better since the 85W adapter can adjust it's output for the 45W and 60W use on the MacBook Air and MacBook, respectively.
I have occasionally used the 45W adapter from my MacBook Air on my 15" MacBook Pro; it works for browsing the web if I fire up a flash site or whatnot, my battery starts draining and it doesn't really charge.
btw, some older United Airline planes only have max 75 watt plugs in the seats--so if you have an 85 watt charger it doesn't work. i carry an older 60 watt when i travel..for my macbook pro.
would not reccomend
I have MBP and my wife has an MBA...I noticed problems with my battery not taking a charge. Battery was bad and the genius said that using the MBA charger could have lead to that. I took a sharpie and marked the chargers so i dont mix them up again...
Apple does not recommend it and you can get some odd behaviors by doing so. Generally, an SMC reset will clear up the behavior if you experience anything.
You like Apple KB articles, yeah?
Apple is fairly non-descript about the potential issues. In my experience it has amounted to some of the following:
1. Not recognizing the higher watt adapters when subsequently used.
2. Improper charging status on the recommend adapter when subsequently used.
3. The obvious, and has been noted, the computer may not charge when in use.
4. As I am sure you are aware, SMC handles a number of functions related to power, including sleep, fans, video and more. Given the complexities of the SMC and how tightly coupled it is with power you could experience a number of issues with other functions it handles.
Apple says don't do it, so you probably shouldn't. The impacts may be temporary (SMC reset can likely fix any symptoms), but only Apple knows if there are larger implications.
Hence, my question. Thanks for some details. As I indicated in my first post, Apple doesn't recommend it (nor do I), but they're vague about any potential problems, beyond not having enough power to charge.
Thank you everyone
