Brand new Pinecil v2 won't boot on PD

[jhutch]

G'day folks.  I was excited to receive the pinecil v2 (direct from main store) and it will start on a 5V source but I can't get it to start at all on higher voltage PD supplies.

I've got a pinecil v2 that I expect to support "USB type C: PD and QC 3.0 12V-20V 3A" running v2.18 (I can see a 2.19 but the changelog doesn't reference PD fixes)

The main one I expected it to work with is a Zendure Supertank which has USB C ports that supply 5V/9V/12V/15V/20V @3A (for 60W) or 20V @5A (for 100W) and works well with my laptop.    I've also tried a Dell D6000 dociking station that supports PD up to 65W  (5V/9V/15V@3A and 19.5V@3.25A).  No sign of life from the pinecil on either.

I've tried using both the red usb-c cable I bought with the pinecil and an existing high quality one I bought for 100W PD charging of my laptop from the supertank.

I've tried changing the "PD Timeout" right up to 50.   

Any suggestions on what I haven't tried?   Maybe I've got a dud?

Thanks.
