Let's build a laptop

[ThomFranken]

I do not fully understand your Ideas here - so maybe it’s pointless - but does that ZC828 mentioned here could be helpful in anyway:

Rock5 does not work on most PD power supplies

For me, RADXA POWER PD 30W is sold out right now. Since I still want to use my PD chargers, I found out that using YZXSTUDIO’s ZC828 (which uses the Zhirong SW3518S chip) as a relay (PD in, PD out, it also supports DC input) can make it work on every PD charger that I have. It can negotiate 20V very quickly and is reliable. I will use this as a temporary solution until a stable U-Boot firmware solution is available. [image]

And do I understand it right that “Let’s build a laptop” would be much easier if one would drop the feature of an external USB Type-C (data) port?

Like just using a powerbank with passthrough and one of these usb-c to dp/hdmi/vga adapters that has an aditional usb-c port where that powerbank could be plugged into.
