My lg g3 is not charging

[AC Question]

It is a lg g3 can you also please link the materials for me to buy from amazon or walmart if possible.My lg g3 is not charging I figured it had to do something with the charging port because I tired different chargers etc. However, still it doesn't charge so I had an idea of installing a wireless charging kit into it. Do you think this will help and cause it to charge because right now it is completely off?
