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 the number of charges: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, a 5,000mAh power bank gives an iPhone 15 (3,877mAh) about 0.8 charges, and an iPhone 15 Pro Max (4,852mAh) about 0.64 charges.

How can I charge an iPhone 14 Pro Max with this power bank?

To charge iPhones prior to the iPhone 15 series, an additional USB-C to Lightning cable is required (not included).

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).
