Counting the capacity and efficiency of the mobile power supply battery:
Ah data x output voltage ÷battery voltage ÷ efficiency = mobile power supply battery Ah (output voltage is typically 5V, the battery voltage is generally based on 3.7V, typically by 85-90% efficiency)
Over-voltage and Under-voltage reminding:
When the voltage is over 5.3V (less than 4.7V), the arrow ˆ (ˇ) will be flashing
