You say "it" and this video is about 2 different devices. One device can charge with usb-c while the other does not have usb-c charging, only ac. If you have a larger portable powder station that has a wall plug it will work, things like jackery/anker 521/bluetti etc. But a regular USB battery bank you can fit in your pocket will not work to charge the Mars 3 Air.
You say you wish it could be powered by usb-c or power bank. All other videos I’ve seen says it can be powered by power bank.
