    Hi ! Random one ! I got a cute cell phone fan for my birthday, and it only has a micro-usb plug. I've bought a micro -> usb-c adapter, but when I plug it into the phone nothing happens.

    I've tested the fan on another device which has a micro-usb port, and it works perfectly.

    Anything I need to do to enable the usb-c port to power the fan? Or potentially a faulty adapter ?

    Thanks !

    I once tried an OTG adapter to PRIV for a WD Passport external HDD and it worked. I tried an OTG dongle that allowed for power input from a USB source, but that was a failure. Then the USB of the PRIV died and was replaced twice by a shop but died again shortly. never tried it on KEYᴼᴺᴱ…

    Too much voltage drawing from the phone's USB port will burn it. Try it on your own risk.

    thanks guys.. in this case it's meant for cell phones, so not worry about the voltage.. I just can't tell if the failure is in the adapter or in drawing the voltage at all

    I would assume the adapter. Do you have another USB-C phone to try it on?

    Thanks ! Not personally, sounds like phone a friend time.. I did have a phone that takes micro-usb and the fan worked there. Will check if the adapter works on one of my old chargers (though again that's still input not output)

    will report back if I test it on another android, but looks like this adapter doesn't explicitly support OTG and that may be the issue.. incidentally the adapter worked with my old bb micro usb cable plugged into my laptop, for both charging and data.
