Question about Microsoft Surface Book 2

Can I charge my Surface via the USB-C port?
Although Surface Studio 2 has a USB-C port, it does not receive incoming power through it. Please use the power cable that came with your Surface Studio 2 to power it.

Normally, you can charge your Surface through the USB-C port. However, we strongly recommend using the power cable that came with your Surface, as charging speeds can be very slow with a USB-C cable (depending on which power adapter and cable you use).
