Can I use my phone as a power source?
Yes, it is possible. The phone/tablet has to support USB OTG, you need an adaptor, and you need the USB device.

Each USB port can provide power to connected devices. This is not always necessary, especially if the connected devices have their own external power supply. But some devices need the power provided by the USB port to function or reload batteries.
What’s the lowest power output of a USB port?
Accordingly, check all the USB ports on your PC. Their number will depend on your motherboard and form factor – ATX vs. mATX vs. mini-ITX as the smallest one with the lowest number of USB ports. The lowest power output is D3, which happens when your computer enters a sleep state.
