Did you buy it from Anker directly? Or via Amazon?
If not it could be a rip of cable trying to be Anker - maybe @AnkerOfficial could check the serial number and see if it matches their records.
If you bought from Anker directly or from amazon (depending on when you bought it) it may be covered under warranty and I’m sure they will give you a replacement.
The good thing is though that it happened at a time when she was able to quickly notice it and not when she was sleeping for example.
Hope you get sorted soon
