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 5500mAh to 7000mAh to power devices.

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

To estimate charges, use this formula: (Power Bank Capacity × 0.7) ÷ Device Battery Capacity. For example, an iPhone 15 with a 3,877mAh battery can receive about 1.92 charges from a 10000mAh power bank (calculated as (10000mAh × 0.7) ÷ 3,877mAh).

How can I charge an iPhone 13 Pro Max with this power bank?

To charge iPhones prior to the iPhone 15 series, an additional USB-C to Lightning cable is required.

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

Slight heating due to efficiency losses in the conversion circuit is normal. The temperature of this Anker Power Bank meets the temperature limits of the IEC62368 certification standard.
