From https://gitter.im/linux-surface/support:

@y2kbugleung_twitter: Does linux or this kernel come with any kind of thermal control during charging? I am monitoring the charge with a meter. I can see the reading jummping from 2A and then 0A and then 2A repeatedly. When I switch to Windows, the reading keeps at 1.x A to 2A.

I wonder which Surface device that measurement was done on, I couldn't reproduce those findings on my SP5/2017 (at least not with the normal charger instead of a USB-C adapter).
