So I had this issue last night. Fell asleep and iPad dropped on floor, snapped the end of charger off inside the iPad port.
I have zero patience and I thought this was going to be a nightmare, but……
After reading everyone’s comments I grabbed a thin scribe type tool and a decent magnet. Seriously took less than 10sec to dislodge.
The broken piece was in as deep as it could possibly go, but all sorted and charging fine.
Thank you to everyone for the info and tips!
