The 100W USB-C PD Compact GaN Charger reaches 100W only with an E-Mark USB-C cable and only when one USB-C device is connected. A standard USB-C cable may limit the power delivered. E-Mark cables, like the Satechi USB-C to USB-C 100W charging cable, are rated to handle up to 100W. The E-Mark cable is sold separately.

Power output adjusts automatically depending on how many devices are connected:

• 1 USB-C PD port: up to 100W
• 2 USB-C PD ports: up to 60W and 30W
• 2 USB-C PD ports and 1 USB-A port: up to 60W, 30W, and 12W

The USB-A port delivers up to 12W.
