Example
Connecting USB Dongle Tester With Mobile Phone:
In this example, the USB Voltage/Current meter Input is connected to the mobile phone power supply unit and on the other side (Output), it’s connected via USB Male to Micro USB cable to a Smartphone. The current displayed is 0.39A (Note: Unit is measured in ampere).
Calculating Power Bank Capacity by Counting how many times it can charge a phone
Calculation of the conversion rate power bank:
Power Bank capacity X 0.8 (20% loss) / mobile phone battery capacity = charging times
EXAMPLE:
- Power Bank capacity: 11200mah.
- Mobile phone battery capacity: 3100 mAh.
Charging Times = 11200mAh X 0.8 / 3100mAh = around 2.89 times.
Converting Amps (Current) to ampere-hour rating (Ah)
Amps x Hours = Amp-Hour
