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 charges, use this formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, an iPhone 15 with a 3,877mAh battery can receive about 0.8 charges from a 5,000mAh power bank (calculated as (5,000mAh × 0.65) ÷ 3,877mAh).

Is it normal for the power bank to get slightly warm during use?

Yes, it is normal. The product meets safety standards with a maximum temperature rise of 118°F (48°C).
