My chuwi lapbook plus is not charging. No chargers available on the market help

It does very rarely and after long break begin to charge but port starts overheating like crazy and after a while it stops charging and will not charge again no matter how i position or what charger will use. Also it happens that battery will show 2-15% but if I remove the charger it will shut off and not be able to turn on or turn on for short time until it drains all charge… it was defected from beginning but have gotten worse quickly.
