It has become apparent to me that charging via USB-C only works properly (fast) when the PBP is on.
The suspicion is that this has to do with PD negotiation failing when the device is powered off. This results in slow standard USB charging.
The graph below shows the charging pattern with the device on (orange boxes) and off (between the two boxes).
I'll talk to the relevant people and ask about what can be done. In the meantime, if you want your PBP to charge at its optimal using USB-C, make sure that its turned on.
This doesn't affect charging via the barrel jack.
It may be a issue specific to the default Debian MATE or other OSs too - haven't checked. Please report below if you've got experience with other OSs.
