A USB Power Delivery charger plugs into 1× USB 3.2 Gen 2 Type-C (DisplayPort/power delivery/G-SYNC), 1× Thunderbolt 4 (DisplayPort/power delivery).
The manufacturer states no minimum USB-C charger wattage for this model. A charger rated below the 250 W it lists may charge more slowly, or may not keep up when the laptop is under heavy load. The manufacturer's manual is the authority on what a lower-wattage charger does.

- A charger with high advertised wattage but no USB Power Delivery support may not charge this laptop at all — wattage alone doesn't determine compatibility.
