Why can't the 733 Power Bank be recharged via USB-C2 port?

The 733 Power Bank has 2 USB-C ports:

 
  • USB-C 1 port is an input&output port. It can recharge the Powerbank and charge other devices.
  • USB-C 2 port is just an output port. It can charge other devices.

 

Therefore, the 733 Power Bank can’t be recharged via USB-C 2 port.
