If you already tried different cables and adapters, then it is possible that the charger port is damaged. So first, before it runs out of charge, you should backup all your data online. On your phone, open Settings > Accounts and Backup. Then choose Backup and do a backup there.
Now, try cleaning the port and see if it charge. To clean, please see the instructions here --> https://www.youtube.com/watch?v=zK8H1B5Sq3g
