    I'm using one right now - have been for a month since my 85W broke. No problems so far.. and it's much smaller.
    Might take longer to charge but haven't noticed any problems performance wise.

  • Not really. You might find that it doesn't charge, or doesn't charge well. MacBook Pro takes a higher wattage adapter (85W I believe?).
