This USB charging hub can power a Raspberry Pi stack. Make sure to use a USB cable that supports USB 2.0, at least a thick one, otherwise the Pi will show low power when booting up. The Pi requires around 5VDC at 2.5A and a suitable USB cable to work well. I plan to use the QuickCharge and PD connectors for a pair of Rock Pis. The display is a great tool to see how much power your Pi is using for development purposes. Let's see how long this hub lasts and update later.
