a bit confused about what is wrong here…
@NothanUmber had the wrong PSU wall plug supplied initially, I think he used an adapter until @embodme supplied him the correct but
but you then mention, type-A vs type-C. …so, I assume you are talking USB?
The Erae is not powered by USB ( * ), it only takes power from the DC psu that’s provided.
then it has a USB-C connection on the Erae for data/midi.
they supplied a USB-A to USB-C cable, but if your computer is usb-c you could use a usb-c to usb-c, but you still will need power (afaik)
probably best bet is to reach out to @embodme via email … I assume that’s their primary support channel at the moment.
( * ) well, at least that’s not what the manual/specs says, and those that have tried have not got it to power on via usb - afaik.
