USB-C charging

Hi @Denys_Pasishnyi! Welcome! And yes we support USB-C Charging from most chargers up to 100W. I have spent some time making sure our charging can support as many chargers as possible, and our battery buck-boost charging architecture supports any charger voltage from 5V to 20V. The Laptop is designed to operate with chargers 60W+, but we can support anything down to about 15W - We added this as kind of an “emergency use” condition, as you are likely to drain the battery while using the system…

…that the internal DC input system is a buck-boost topology capable of handling any input voltage from 5 V to 20 V, so I suspect this is a bug in the control firmware.
