A missed opportunity though. If it’s USB-C powered, it could be even smaller and Apple could simplify its BOM by including a MacBook Pro charger with it.
If it was USB-C powered people would be complaining about the size of the external power supply.
If it only had one USBc input, how could it supply enough power for 5 USBc outputs ? Well ok, 3xTB5 + 2xUSBc, but still ?
Does it work 24/7 or have two power sources? Can you charge the powerbank at the same time so it will rely on the battery only when the power is down?
Many power banks support pass through charging where it powers attached devices while also charging the battery
