I discovered that my phone will power up the Raspberry Pi. But I needed this Micro USB to Micro USB OTG cable. This will power-up my Raspberry Pi directly from my mobile phone.
I purchase most of it from Adafruit. Now the Micro USB to Micro USB OTG cable, I purchased from HakShop. https://hakshop.com/products/micro-to-micro-otg This matched Nintendo's colors.;)
