XD Design Bobby Tech Anti-Theft Backpack Wireless Solar Panel Charger USB/Type C

USB-C port can not be used as a power source. When it comes to this port, electricity can flow only in one direction, from outside the backpack towards inside which is pretty much useless and this backpack stating it has an USB-C port is miss leading.Cable setup inside is complicated and messy, too many possible inputs and outputs that could be better managed using one central power bank as a middleman between solar panels and devices

It may be good backpack after some improvements. Not good as day pack for more than one day.
