Power aggregation?

I’m wondering if there is a way to aggregate power from multiple power banks. It strikes me as a possibility if a usb power hub could be employed in reverse (i.e., turn input into output). This would however, in theory be “in series”.

Curious if any others have explored this?


In theory you could daisy chain from one power bank output to another input though I wouldn’t recommend doing it because you would be using up cycles and stacking inefficiencies of converting from wall electricity to storage for each chained item.

Thanks Arthur. I understand I think that daisy chaining would be, at best inefficient due to the fact that the cells that make up the pack are non-contiguous. That being the case, the concept of an expansion port would be interesting in lieu of a power manager that could normalize the draw in a bus like distributor - if you will.
