FAQ
Q1 Q:Why does my power bank only show 20,000mAh? A1 A:The actual capacity of this power bank is 40,000mAh at an output voltage of 3.7V. The labeled capacity of 20,000mAh at 7.4V is just another way to express the same energy output. There is no discrepency, so don’t worry. Q2 Q: Why is my power bank providing fewer charges than expected? A2 A: Charging energy loss from battery-cell and circuity inefficiency causes a capacity reduction between 30% to 45%. A fully charged Anker 40,000mAh power bank delivers between 22,000mAh to 28,000mAh to other devices. Q3 Q: How can I estimate the number of charges for my device? A3 A: To estimate the number of charges, use this formula: (Power Bank Capacity × 0.65) ÷ Device Battery Capacity. For example, an iPhone with a 3,877mAh battery can receive about 6.7 charges from a 40,000mAh power bank (40,000mAh × 0.65 ÷ 3,877mAh).
