Q: My ipad mini is not charging

my ipad mini is not charging. i tried main wall but nope. 0% battery left help

i live in the UK and i dont think theres any apple store near me

I didn't find any authentic and good solution to charge and make it ON my iPad mini device so writing here to get a reasonable solution. My iPad mini charging drained out last week and I charged it for like 3 hours with charger 'input 100-240V~50/60 Hz 0.15A', while charging, the device heated up(too hot when hold it) and device remained OFF and not turning ON now. i tried many other power charger to charge it but now it's not charging and even not turning ON. Please let me know what can be the issue and how can I solve it.

Looking forward a healthy solution.

thanks
