Actually, I'm not sure this is even a current issue. You can safely use a power adaptor or display with higher or lower wattage than the adaptor. Find the wattage in the AC Charger section towards the bottom: If your Mac uses USB-C to charge, you can charge your Mac notebook with any USB-C power adaptor or display. And, this is only relevant to an over-current issue. Hold the Control key and choose Apple menu > System Information, then select Power. Having seen this happen (not on a computer,) I'm reasonably sure of my assumptions despite not having my EE degree. That means an 85-watt charger will supply 85-watts of power regardless of what it's connected to unless the device provides over-voltage and over-current protection that is still working. Ask Apple if they would honor a warranty under such a circumstance.Ĭurrent is supplied on an as-needed basis and that means any level of current before the supply burns out. Nor have I seen wiring diagrams so I can't say what is inside on a motherboard or a charger, but if a charger lacks over-current and/or over-voltage protection and there is a short in the computer's power circuit, then the computer could draw more power from a charger that is over-rated for the model. This is the 13-inch MacBook Air (2022) vs 14-inch MacBook Pro (2021): The battle between two powerful yet different Apple notebooks. MacBook Air (Retina, 13-inch, 2018) - Technical Specifications (UK) Languages MacBook Air (Retina, 13-inch, 2018) - Technical Specifications Display Retina display 13.

However, I've never been inside that particular model since I don't own one.
