Keep in mind that some manufacturers of power banks exaggerate their devices’ capacity. As a result, the calculations are not accurate and are merely estimates. Another factor to consider is that the capacity of power banks reduces after 100 to 500 charge/discharge cycles. Thus, the charging time will substantially differ from what you calculated if you think you’re close to or have passed this number. The thing with batteries is, they have a 'memory'...

Many modern power banks are designed to automatically stop charging when they reach full capacity, but it’s still recommended to disconnect them to extend battery life.
