Yes once in a while I do use it when plugged in but don't use it moving around. Thanks for the advice.I’ve used Anker, RAVPower and Satechi and they all worked fine.
Have you tried cleaning out the charging port?
Also, do you ever use your iPad while it’s plugged in and getting moved around? I’ve seen more reports here of broken USB-C ports than broken Lightning ports so I’m guessing USB-C is a bit more delicate.
Thanks. I turned it off last night, plugged it in this morning and it's charging now, so still might be an idea to get an extra backup charger. Weird.I had this happen before on my Air 4. Woke up one morning and it hadn’t charged at all overnight (I use the included apple charger). Hard rebooting wouldn’t fix it either. I was ready to bring it in for service but it ran completely dead and then when I plugged it in started charging again. Hasn’t happened since.
