The boost system of the mobile power supply:


The boost technology basically adopts the DC to DC boost mode. The efficiency of technology conversion in China is generally low, generally in 50-70%. Taiwan is in 75-80%. The United States is relatively high. There is also a high efficiency, but a high demand for the consistency of the core, so it is rarely used.


Calculate the power output according to the conversion efficiency of the product:

Actual output capacity = (mobile power capacity 7800mAhx3.7Vx conversion 85%) /5V=4906mAh
