85watt supply on macbookair - is it safe?
I have an 85watt magsafe power supply that outputs 16.5 - 18.5volts. My new macbookair uses a 45watt adapter on 14.85volts. Will the macbookair be ok if I use a magsafe2 adapter on the old 85watt supply, as I would like to use it as a second charger.
MacBook Air (13-inch Mid 2013), OS X Mavericks (10.9.1)
