@idonthatevests Some devices can power on SSD via USB-C OTG with power delivery. Fairphone 5 with Fairphone OS can do it, I use it with a sandisk extreme SSD 500Go, it works very well. On the other way, if I want to use an HDMI dongle with SSD attached, for example to play a movie with my FP5 from the SSD, I have to power the dongle with external power because FP5 can't deliver enough power to SSD and dongle with HDMI/audio output in use for a stable playback. Now I still don't have a FP5 with UT on it so I can't test with this OS for now (will come).
