I bought those of these shiny "GAN chargers" (Baseus, etc.), I tried multiple brands and it seems like this is constant across this type of charger: it cannot be used to charge a X2100.

I don't know if this is a:

I plugged some USB tester in-between and it is losing power every second, I can see on the first bootup of the device there's some 20V and some current going through and then it dies.

I am willing to experiment / patch my EC / spend time on Ghidra to reverse this, but I wanted some input from the community if they ever experienced this. :)
