Pencil at 3% plugged into tablet, shows it’s charging fast, but @3%?

Pencil stopped charging via the cable and adapter, which I had to buy! Tried to charge by plugging it into tablet and it worked fine for awhile. Could be a coincidence, but upgraded to 13.4.1, now pencil says 3% of battery life. When plugged into tablet , it charges extremely fast, but it’s not charging at all. It still says “pencil is at 3%” , so I’m debating buying another one. I tried to unpair the pencil and repair it to my iPad Pro, it didn’t want to pair . I finally got it to pair after restarting the tablet! Still charging super fast , but it’s not actually charging !
