iPad Pro charging

Some PowerBank devices support the USB-C Power Delivery (USB-PD) standard.

An iPad Pro with a USB-C port can either be charged via its USB-C connection from an external power source - or can supply power to external devices. USB-C PowerBanks that can both supply or receive charge via single USB-C port often have a button or switch with which to change its mode of operation.
