iPad not charging

If your iPad charges slowly or won’t charge

Follow these steps and try again after each:

1. Make sure that your power adapter can charge your iPad. It's best to use the power adapter and cable that came with your iPad.
2. Check your charging cable and USB adapter for signs of damage, like breakage or bent prongs.* Don't use damaged accessories.
3. 
4. 18W power adapter and USB-C charging cable
5. 
6. 12W power adapter and Lightning to USB cable
7. Remove any debris from the charging port on the bottom of your iPad, then firmly plug your charging cable into your iPad. If the charging port is damaged, your iPad probably needs service.
8. Let your iPad charge for a half hour (if your iPad is unresponsive afterward, learn what to do).
9. Force restart your iPad: 

• • If your iPad has Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Top button until the iPad restarts.
  • If your iPad has a Home button: Press and hold both the Side (or Top) button and the Home button until you see the Apple logo.

1. Let your iPad charge for another half hour.
2. Use a wall power outlet and check for firm connections between your charging cable, USB wall adapter, and wall outlet or AC power cable, or try a different outlet.
3. If your iPad still won’t power on or charge, take your iPad, charging cable, and charging adapter to an Apple Retail Store or Apple Authorized Service Provider for evaluation. You can also contact Apple Support.

Yes I know. The last part got added when I pasted it in.

Did you try a Force Restart? Plug directly into wall outlet, no extension cords?

Then you will need to wait until a store opens to take it in.
