Nice design ![:-)]( "Smile")
One thing is there I would have done in an other way. Probably half your energy is used for the DC->AC->DC-conversion. Even if there is no power bank that can give enough amperes at 5V, there are power banks that can deliver 45, 60 or even more watts. There are little PCBs or even moulded cables, that trigger USB-C PD outputs to give a certain (higher than 5V) voltage. Using one of those, you can power the system by e.g. 20V. Inside your machine, you can have one or more DC/DC-converters which step down the 20V to the needed voltage. The whole setup will become far lighter, less bulky and more power efficient![:-)]( "Smile")
