While I have definitely done this a few times, one of my MacBooks could draw more power than the power supply could deliver and there was a particular computer game that I discovered I could “only” play for about five hours before the laptop shut itself off. Because it was having to draw supplemental power from the batteries to keep up.

IIRC the next generation of MacBook was the one that came with the larger power brick, which didn’t at all surprise me after that experience. Then they switched to GaN to bring the brick size back down.
