I highly agree. It's never that great of an idea, in my opinion to
mix-match chargers, that's only asking for trouble in the long run.
Now, if you have to products same make same model same everything, then,
that's a different story, but...

Hi all,
They will all work with each other although, electrically, there are some
things you should note:
1. If a unit is expecting a 45 watt power supply and you give it an 85 watt
power supply, you may decrease the life of both the battery and the charging
unit. consider that you're pushing almost twice the wattage into the
charging unit as it is rated for. In some cases this will burn the unit out
faster, and in some cases, it will simply burn it out immediately. Also,
consider that heat is one of the most damaging factors in battery life, if
an increased amount of power is being pushed onto the battery, it will heat
up more, thus, the battery will get hotter during charging probably reducing
its life.
2. The other direction, charging with a 45 watt when expecting an 85 watt
power supply, does not hurt anything really. It will simply make the
charging process take longer.
3. You may get away with things for a while, but I recommend that you use
the proper rated power supply, especially if you have any warranty left on
the machine.
Later…

While not quite the same setup my MacBook Pro charger works just fine in
my wife's old little MacBook and vice versa. Main thing is that her power
supply is not quite as big (physically and wattage) so it takes longer to
charge up my laptop if I'm using her power supply. I would assume similar
things with the Air and your MacBookPro where the Air uses a 45 watt power
supply:

While the current MacBookPro has an 85w power supply

So I think whomever you passed the MacBookPro along to would appreciate
getting the correct larger power supply.

It should be, the macbook pro is a higher wattage charger, so, assuming
it fits, it should work, though of course it won't charge any faster.

I am expecting my new macbook air to arrive tomorrow. Does anybody know
if the charger from the macbook pro is compatible with the 1 from the
macbook air.
If I do sell the macbook pro, if the chargers are compatible, I can
package the macbook pro with the brand new charger. Knowing my luck,
this won't work. I just wanted to check and see if anyone knew for
sure?
