FQA:
Q:Power bank has two regular standard of capacity , one is the battery capacity, the other is the rated capacity. The 20000mAh power bank being labeled 20000mah/3.7v but the rated capacity is 13000mah/5V. Why?

A:The most important reason is the conversion rate. Because most of power bank's battery voltage is 3.7V, and power bank needs to increase the voltage to 5V when charging the mobile phone, which making the power bank's conversion efficiency only 3.7/5=74%. Also include generated heat when battery voltage boosting, and various of wire consumption, Electricity and self-consumption.
These add up to 30% -40% of the power of the mobile power supply, so the 20,000mAh mobile power supply can actually only be used 13000mAh by us.
