I tried everything but iPad won’t charge.

Battery? Charger? Cable? We, just users like you, cannot diagnose that kind of issue remotely, sorry.

If you already tried (to no avail) ALL the steps provided here:--> If your iPad won't charge - Apple Support, contact Apple Support directly, using this link:--> Get Support , or make an appointment and have your device inspected at an Apple

Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector

After checking it out, they'll give you all the available options.

Regards

Giulio
