So I guess you set the Voltage on the powerbank. My understanding of PD is that there’s a negotiation between compatible devices so that you don’t send 12v to a phone expecting 5v
Anyway this raise a question in my mind, given that USB C plugs are reversible, how do you ensure correct polarity … i guess one way won’t work, but I am unfamiliar with the usb C plug pinot and how ‘smart’ it is when inserting in compatible devices.
The way I remember it is Voltage is pushed and Current is drawn, so a device will consume what it needs.
The Syntakt doesn’t need 2A it just needs 1.2ish Max at boot iirc … the digitakt will draw less current , so the spec of 1.67A is fine for both cases … however, let’s assume e.g. the AR draws more so it may not be safe to power that with that powerbank (if needing >1.7A) even though both are specifying 2A 24W PSUs on the rear chassis
I’d be nervous thinking about the solution as power delivery though as it conveys a certain negotiation happens, which can’t with the DT … so taking a laptop supply which can run at 20v 12v 9v 5v and plugging that in could be an issue, it works with my laptop and phone as they are proper PD setup to prevent any issues
