Compatible with iPhone 16/15/14/13 Series, Samsung, MacBook, Dell, and More 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 Prime 20,000mAh Power Bank offers an estimated 11000mAh to 14000mAh 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 3.3 charges from a 20,000mAh power bank (calculated as (20,000mAh × 0.65) ÷ 3,877mAh). How do you calculate the watt-hour capacity of this power bank? This power bank uses four 5,000mAh cells at 3.6V. The calculation per cell is 3.6V × 5,000mAh / 1,000 = 18Wh. Multiplied by four, the total capacity is 72Wh, which is below the 100Wh limit set by airline regulations for carry-on electronics.
