Guys,
I have a 2015 MacBook Pro 13" and with it I use a mains power plug with MagSafe connector rated with an Output of 16.5V and 3.65A Max.
The thing is I have been given another MacBook Pro connector only this one is from an earlier 2014 model which has a higher Output of 20V and 4.25A Max.

My question being:- Is it safe to use the higher charge rating from the 2014 MacBook Pro's 20V at 4.25A with the 2015 MacBook Pro?
