Harbor freight jump pack, broken input jack, repairable?

I received a harbor freight Cen-tech battery jump pack as a gift. It got knocked over when I took it camping to charge my phone and inflate my bed. Now the input jack (the part with the prongs) is loose and won’t attach to the charging cord easily and doest seem to be charging when it is. Is it fixable? Lots of videos on how to swap out the battery inside but nothing on fixing that part. I was assuming on how easily it broke there would be more about it.
