Are power adapters unique to the their Macbook?

[LebanonDon]

Hey Guys,

I recently had my power adapter stop working and I was thinking of taking it in for repairs. The thing is that I'm not 100% sure its the adapter that came with my computer because a bunch of friends have the same laptop and we might of got the adapters mixed up.

Anyways my question is, is there a serial/unique identifier on that adapter that is paired with your computer?

Any help would be great, thanks!

what he said.

however, macbooks, macbook airs, and macbook pros all use different adaptors.

like what they say.

but...

45W adapter - macbook air
60W adapter - macbook
85W adapter - macbook pro

MacBook air - can only use 45W
MacBook - can use 60W and 85W
MacBook Pro - can only use 85W

so make sure you have the 60W adapter.

85W adapter - macbook pro

MacBook air - can only use 45W
MacBook - can use 60W and 85W
MacBook Pro - can only use 85W

so make sure you have the 60W adapter.

Or I guess you could say "make sure you have at LEAST the 60W adapter" ?

I was thinking of getting an 85W adapter to use at home on my desk. That way if I ever got a MBP or a friend brought one and needed power, I'd be covered for all scenarios.
