Why is my power bank providing fewer charges than expected?

The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker Nano Power Bank offers an estimated 2,750mAh to 3,500mAh to power devices.

How can I estimate the number of charges for my device?

To estimate charging cycles, use this formula:

(Power Bank Capacity × 0.65) ÷ Device Battery Capacity ≈ Number of Charges.

For instance, charging a 3,000mAh device using a 5,000mAh power bank would offer approximately 1.08 charges.
