Hello lel4355.
Welcome to Apple Support Communities. We understand that you are not able to charge your iPad using the Anker charging cable. We are happy to help.
Let’s try the steps here: If your iPad won't charge - Apple Support
We also recommend trying an Apple branded charging cable or another charging cable to see if your iPad charges. Are you able to charge another iPad or Apple device using the Anker charging cable? Let us know the results.
If you are still unable to charge your iPad with the Anker charging cable, we recommend contacting Anker here: Anker Support -message
