Mini Mobile Power Capacity Tester KCX-017, USB Voltage-KCX-017 White

1. Mini mobile power capacity tester

2. Test content: battery voltage, current, discharge capacity

3. Voltage: 3 - 7V / 50mA - 3500mA

4. Capacity: 0 - 19999 mAh

5. Mobile power capacity test: The first mobile power is fully charged, the electricity meter measured data is cleared. Mobile power connected to the load (or phone) discharge (divided into multiple discharges) after the tester discharge displays the output capacity value (in mAh), then by the following formula: mobile power capacity (mAh) = output capacity mAh x output voltage 5V / mobile power efficiency (default 0.85) / mobile power Battery voltage 3.7V.

6. Mobile power Battery capacity is calculated according to the following formula: Mobile power efficiency = Output capacity mAh x Output voltage 5V / Mobile power Battery capacity mAh / Mobile power battery voltage 3.7V

7. Test method: First the phone battery runs out, then to charge the phone using a mobile phone charger connected to the tester, the tester after charging displays the output capacity, and can be calculated by the following formula Battery capacity: discharged, the battery capacity = tester display capacity; start charging, tester display capacity of the mobile phone battery capacity of about x0.9
