Battery capacity calculation formula: Actual capacity (mAh) = (Nominal capacity × 3.7V × Efficiency) / Output voltage (5V).

The efficiency of a high-quality power bank is typically between 85% and 90% (0.85–0.9), with the remaining electricity converted into heat. Taking a 5000mAh power bank with an efficiency of 90% (0.9) as an example: (5000mAh × 3.7V / 5V) × 0.9 = 3300mAh.
