Hey guys. This is my issue. I have one device I primarily work with which is a one plus x. I love flying after work but sometimes my device's battery is too low I'm scared the phone will die during flight. Now I know what your thinking why don't I just plug in my phone it's because at my work often not able to charge my device. My question is.. Has anyone used an OTG micro USB cable from the standard Controller and plugged in a cable to their device for power? I could see advantages and disadvantages of this but I'm just curious to know of this has worked, and if you can even get power output from the controller to the phone itself. Let me know thanks.
