Exactly how much power can the OP1-F *deliver* through USB-C? (Polyend Play+ crashing)

Does anybody know exactly how much power an OP1-Field can deliver through USB-C?

My Polyend Play+'s one and only USB-C port can transport audio+midi, which is great, but it also needs power through that port (5V/1A). I would love to connect it to my OP-1 Field via USB-C to reduce the cable mess. The Play+ will start alright that way, and I can play around both machines to enter the MIDI I/O setup, but as soon as both machines get busy playing tracks, the Play+ shuts down – I assume because of lack of adequate power, not because of a bug/crash.

I can connect the Play+ to my new 2024 iPad mini directly via USB-C for audio+MIDI, and the iPad seems to be able to power the Play+ just fine. So either the OP-1 Field doesn’t provide enough power, or there is a bug going on?

I recall @Wolfshoek went through their own personal hell already to figure something out with another piece of Polyend gear, but maybe if we figure out exactly what the power output is first, we can get that ball (re-)rolling?

Meanwhile, if this is of interest to anybody finding this post, my setup currently is:

  • the Play+ USB-C port is for power only, through a USB power-bank,
  • the Play+ MIDI in/out TRS jacks are connected to the OP-1 USB-C port via a small-ish LEKATO MIDI to USB C audio interface for MIDI notes, clock/sync, transport,
  • the Play+ audio out is connected to the OP-1 line-in so that I can listen to it and record it.
    This allows me to start the Play+ from the OP1F, send notes to the Play+, receive audio & notes from the Play+, etc. That’s a lot of cables still, and also prevents me from powering the OP1F at the same time, so I’m investigating wireless MIDI for the Play+ using a Bluetooth dongle, but that’s another rabbit hole.

Thanks
