    I have MBP 13", 15" and 17" - from 3 years old (santa rosa) to the current models. Can I share their power adapters? If buying new power adapters, am I best to buy them all at 17" power?

    It's generally recommended that you use the 85W adapter if you're going to share adapters. Using the 60W adapter on machines that require the 85W adapter can be done, but the brick will get very hot and your machine might not get the power it requires to do a task.
