Calculation Method of Mobile Power Capacity:
The mobile power supply is fully charged and connected to KWS-1902C(data cleared first) and electrical appliances, and discharged until it stops output.
Method 1: Mobile power capacity = KWS-1902C Measured mAh Data x Output Voltage + Battery Voltage + Efficiency
Method 2: Mobile Power Capacity = KWS-1902C Measurement mWH: Battery Voltage Efficiency
(General mobile power output voltage is 5V, battery voltage is 3.7V, efficiency is about 85-90%)
