AirPods Pro case charges very slowly
Since a few months back, I began to have an issue with the charging time for my AirPods Pro charging case. I have tried a genuine Apple USB-C to Lightning cable, plugged in to the laptop USB-C port and it takes several hours to charge the case. Tried another Lightning cable from a wall adapter, same thing, hours of charging a teenie tiny case. I'm sure this isn't normal. Please advise on what the issue could be.
Thank you in advance!
