I got a 72W USB C power delivery adapter, better have an overhead with no-name brand chargers. It can only power the tablet, it does not charge the battery. I measured it at the wall and it’s uses 15 watts on idle and in games it can get up to 40W (!), but it still doesn’t charge the battery. It just prevents it from going down. The standard 30W round plug adapter charges and powers the tablet at the same time. I use the BIOS settings mentioned in earlier in the thread.
