Both powerbanks use micro USB connectors, but they are fairly substantial, and also slightly recessed which protects them from being lifted off the board to some extent. The youtube user bigclivedotcom in the video earlier in the post tears down both the Poundworld and Poundland powerbanks.
You could possibly remove the 18650 LiPo and put in a smaller one *and* squeeze the mm in to the case at the same time.
14500 cells are approximately the same size as an AA battery, and the charger PCB would work with these too, since these powerbanks charge with a pretty modest charge current and use some less than spectacular capacity cells.
If you squeezed all that in to the case and stuck one of those tiny OLEDs on the front you would have the ultimate laptop.
