The battery levels have their own time of self-discharge, whether you charge up the device or not. It requires a small amount of energy to keep working. And, the battery remains charged for a while.

A durable power bank can last up to 6 months with a small loss of charge, and on the other hand, the lower quality power bank cannot retain the battery charge for a month.
