I have some news.
I made some measures on the Argus energy consumption. I have posted them here:
Regarding the use of an usb power bank I have come to the conclusion that they are not suitable for this purpose. Some power banks auto shut off for the low energy flow of the Argus camera in stand by mode (Orico 20.000 mAh, TeckNet PowerZen P3 16750mAh).
The only one that I find to keep powering the cam is the Anker Powercore 20100 but I noticed the duration of the battery is poor (about 8 days with an average 15 min/day of usage). I can't explain that. I suppose the circuitry of the power bank has a self consumption that is low but not insignificant when you consider a 24/7 usage.
Personally at the end I chose to use the usb powered mode with a mini ups as bakup. If someone is interested I used this mini ups (you can find it also in some china retailers):

To be clear, I meant the cam is connected through the usb cable to the electricity grid.
Thanks for the idea here.
I also have hooked up to the usb input.
I connected the usb power lines to a cheap solar powered light I got from Banggood. I simply opened the solar powered light, disconneced the light and connected the usb power lines directly to the 3.7V lithium battery.
