Fast charging issue in S20 FE 5G

[dops]

Hi community. I own a S20 FE 5G. Sometimes what happens is when I connect it to the provided charger and my realme power bank, fast charging doesn't happen. When when I reconnect phone to the power source, it starts fast charging again. What's the issue I can't understand it. Please help
