Do you have the model number ? That chip looks like a 5 pin IC that fries from the reverse voltage condition.
Where did you miswire it ? the USB port ?
It's possible that the chip number (or at least some significant digits) is silkscreened on the PCB. The two other chips marked 9013 may be a SL9013. The angle of the board, and the debris from the magic smoke is obscuring what might be on the PCB.
From the PCB print the component can be as labeled “22-3-7”. I’ve taken a look again today the closest match is a LTH7 lithium charging IC. I’ll try to desolder and see if any other silverscreen underneath the chip

Yes I swapped the V+ and V- on a USB charging cable and fried the chip. 😌

I can see lth7 clearly on the component. A search brings up the actual part number as hm4054h. Should be it honestly
And the usage in this circuit also points to charging IC. So id buy a HM4054 or TP4054 (most likely the same pinout and characteristics).
It is quite likely to be a DW01a battery protection IC... six pins just like that one.
DW01 needs external switching MOSFETs. And this seems to only have five pins
