BitBrick K1: USB-C Power Delivery voltage

Hi,

Did I understand it right that the BitBrick K1 will not do Power Delivery negotiation when powered via USB-C but simply use power at the default 5V?

And, the SBC itself will peak around 5-6W. Additional power allocation should be made for the M.2 boards and USB accessories connected, which may go up to 15-25W (= 3-5A)?

Thanks
