Notebook power supply

Hello, I need a charging cable (USB-C) with a Swiss power connection (plug) for my HP Elite x360 830 13 inch G9 2-in-1 notebook PC. Which one do you recommend? It may also be one that charges faster.

Which one fits the Dell Latitude 7490 notebook?

I would like to connect my somewhat older notebook to 2 HDMI screens, the notebook has USB A ports and a USB-C port but without video transmission. Can I connect the screens using an adapter - presumably to the USB-A port?
