My charger port pin got broken

@merlinprince not much you can do other than to replace the charging port. Since iFixit does not yet have a specific guide for that, use something like this video Replacement charging ports are available at many online places like this Example only and not an endorsement of the seller

While you work on your PSP, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
