Hello U.Hardegger,

I assume that you want to use the mouse with a mac? Or is this already a new USB C power connector on a Windows computer?

Unfortunately, Logitech does not yet offer a USB C-based dongle. A manual connection to the mouse is unfortunately not possible without a dongle!

Therefore I recommend the following product:

This should work without any problems in combination with the mouse.

Greetings Andreas
