Why is my power bank providing fewer charges than expected?

The decrease in charging capacity is attributed to an energy loss of 30% to 45% in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) can provide approximately 11,000mAh to 14,000mAh to power your devices.

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

You can estimate the number of charges using the formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity = Number of Charges. For example, charging a 3,000mAh device with a 20,000mAh power bank would give you approximately 4.33 charges.

How long does it take for the power bank to recharge?

The recharge time depends on the power of the charger and the ambient temperature. Using a 30W PD charger at 77°F (25°C), the A1383 model takes around 4.5 hours to recharge.
