One is very right - if you blindly apply max power without proper fusing / control chips and signaling, you will damage your cables and Mac hardware. I’m not going to vote either way until an edit makes it clear what Chris is saying here. | |

A charger's rating in watts describes only the amount of power the charger is capable of delivering. An 85w MacBook charger, if plugged into a fully charged MacBook, won't deliver 85w of power — it will only provide what the computer asks of it, only the very small amount of current necessary to keep the internal battery fully charged. There's nothing electrically wrong with using a charger with a smaller rating, save that (as you point out) the computer battery may run at a deficit if the computer's being used. | |
