The charger supports the following USB-C Power Delivery outputs:

• 5V up to 3A (15W)
• 9V up to 3A (27W)
• 15V up to 3A (45W)
• 20V up to 5A (100W)
• 28V up to 5A (140W)*

*28V operation is only for devices capable of USB-C Power Delivery Revision 3.1 with Extended Power Range (EPR).

Note: For Apple Silicon based Macs with 140W charging it will be required to use the Apple USB-C to MagSafe cable to achieve the full 140W. (These systems cannot support past 100W when using USB-C to USB-C as their USB-C ports do not support EPR.)
