Why exist this difference?
The most important reason is the conversion rate. Because most of the 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 3.75/5=74%, Also include
generated heat when the battery
voltage boosting, and various wire consumption, Electricity, and self-consumption. these points add up to account for 30%-40%
of the power of the mobile power source.
So the 20,000mAh power bank can really be used by us only about 13600mAh.
Also, The conversion rate of the entire mobile power industry is basically in the range of 60%-70%. Please kindly noted.
