When charging a 16" MacBook Pro, the required cable depends on the chip model. For M1 and M2 models, only use a USB-C to MagSafe 3 cable; for M3 and M4 models, you can use either an EPR (140W / 240W) USB-C to USB-C cable or a USB-C to MagSafe 3 cable.
Charging power also changes with battery level. When the battery exceeds 80%, charging power decreases automatically to protect battery health.
