Chosen Solution

A charger broke inside my charger port so I took the speaker apart and got a new charging port but I have no idea how to solder it on. Any help?

Some form of magnification head magnifier, usb microscope, magnifier lamp soldering iron or hot air station (really steady hand if using soldering iron) rosin flux (recommend over and above what is in rosin core solder) solder braid for removing any solder bridges Recommend watching Youtube charger port replacement tutorials using soldering equipment Practice soldering technique on junk electronic circuit boards before actually attempting repair on your speaker unit.
