Mi power bank disassembling required a semi-soft and flat prying tool for back plate removal and Phillips #0 and Phillips #000 size screwdrivers. You can use a metal spudger to slide in the internal frame if needed. iFixit Essential Electronics Toolkit includes all of the essential tools.

The nut driver in the photo isn’t usually required. I used it to press the bent aluminium case corner back into shape when the internals were pulled out.
