It'll be fine. When my current adapter catches fire (the way they all do), I plan to replace it with an MBP adapter, in the hopes of procuring a slightly longer lifetime from its slightly thicker (though equally defective) wiring.
uhm....they all do?
okayyyyyy then, no more leaving it plugged in over night or when im not home....![]()
Well, maybe that was a slight exaggeration :^)...but yeah, keep an eye on that Magsafe--particulary where the cable connects to the laptop. That's where they tend to fray/fry.
