Verify your laptop charges via USB-C PD at 100W

Confirm that your device accepts 20V 5A over its USB-C port before ordering. The adapter also negotiates 90W, 65W, 45W, 30W, 29W, 27W and 15W profiles for compatible hardware. Check the connector is USB-C and not a proprietary barrel jack.

CE and FCC certified with multi-voltage input

The charger operates on 100-240V 50-60Hz mains worldwide. GaN construction keeps the 6.77 by 5.55 by 1.93 inch enclosure compact while maintaining efficient thermal performance. No fan is fitted so operation is silent under normal load.
