As an electronics designer myself, I would find it hard to trust the AliExpress board.

Without the design files, running a failure modes and effects analysis on the board is difficult.

There's also no guarantee that each board you get is built identically. Some parts or the whole design could be changed between orders.

If I was designing a power bank board professionally, I'd be putting it through the ringer - environmental, mechanical, component level short circuit, load short circuit, load power injection, input over-voltage, input transient, RFI/EMI susceptibility, etc. Do you trust that all that has been done on a board that is representative of what you've received?
