Charging issue

Hi team,
Not sure what can be the issue but when i connect my Asus 6z for charging at first it shows charging in the lock screen instead of fast charging as a result it charges slow after connecting for two three times it shows fast charging.
Can someone please explain why this is happening.
Regards
Rahul.

have you recently changed charging port from regular point ? or do you use spike buster / extension card with other plugs in ? if so try at regular port where you use to charge everytime
check with adaptor/cable quality once
