sorry I don't know, don't have any of these mini consoles. maybe the adapter you are using to power the psc is just enough for the console itself?
Then why does it sometimes work?
EDIT: I get the PSC to blink (so, it recognizes AutoBleem) with the external HDD connected to the OTG cable and with the latter connected to the PSC's Micro USB port by taking the OTG cable from the PSC's Micro USB port and putting it back. Since I sometimes have this problem, I have to do this process when it happens but I'm worried if this messes up the external HDD since for some reason the external HDD automatically turns on as soon as it's connected to the OTG cable and with the latter connected to the PSC's Micro USB port even with the PSC turned off but what choice do I have? Since the external HDD automatically turns on if connected to the OTG cable and with the latter connected to the PSC's Micro USB port, I only connect it to the OTG cable and with the latter connected to the PSC's Micro USB port when I want to run AutoBleem. Also, the external HDD doesn't turn off even after turning off the PSC and the PSC's adapter makes a noise when turning off the console with the external HDD connected to the OTG cable and with the latter connected to the PSC's Micro USB port, so one more reason to connect the external HDD to the OTG cable when wanting to run AutoBleem. Maybe the power supply doesn't provide enough energy to power the PSC and its external HDD so that makes the PSC to not recognize the external HDD, but if so, why does it sometimes work?
@esmith13 said there was nothing to worry about as long as the power supply was 5V only, not QC (like my previous power supply, which I didn't even try). Maybe it's not a decent power supply?
EDIT 2: Now, when turning off the PSC with the external HDD connected to the OTG cable and with the latter connected to the PSC's Micro USB port, the PSC turns on immediately afterwards. Also, the external HDD stopped working for good because the PSC doesn't blink (so, it doesn't recognize AutoBleem) when turned on with the external HDD connected to the OTG cable and with the latter connected to the PSC's Micro USB port and even two PCs say to insert a disk when double-clicking it in File Explorer on Windows. I find it odd that this external HDD stopped working when I bought it April last year.
EDIT 3: I bought another 2.5" 1 TB USB 3.0 external HDD and when connected to the OTG cable and with the latter connected to the PSC's Micro USB port, the PSC always blinks when turns on (so, it recognizes AutoBleem) unlike with the previous one so I don't have to take the OTG cable from the PSC's Micro USB port and put it back (maybe the previous external HDD was faulty from the start, which is odd).
This external HDD turns off some seconds after turning off the PSC unlike with the previous one (again, maybe the other external HDD was faulty from the start, which is odd) but since it still automatically turns on if connected to the OTG cable and with the latter connected to the PSC's Micro USB port and the PSC's adapter still makes a noise when turning off the console with the external HDD connected to the OTG cable and with the latter connected to the PSC's Micro USB port, I only connect the external HDD to the OTG cable and with the latter connected to the PSC's Micro USB port when I want to run AutoBleem.
Also, when turning off the PSC with the external HDD connected to the OTG cable and with the latter connected to the PSC's Micro USB port, the PSC no longer turns on immediately afterwards.
I just hope this external HDD lasts longer than the previous one since the latter didn't even last a year.
