How do you power the Ubercorn to the two screw terminals?
Do you cut a spare usb cable and connect GND and V in?
And then, from there how to power the Raspi?
From the product site:
If you connect a power supply to the two screw terminals, then it’ll back-power your Pi too. With a single Ubercorn and good-quality 2.5A power supply, you can connect the power supply to your Pi and it’ll provide sufficient power for Ubercorn also.
But that’s not very clear (for me).
Does someone have an image to share how s/he connected this together?
