How many times can charger my phone?
Number of charges equals = (Power capacity of Power Bank* battery conversion efficiency* phone inner core conversion efficiency (80%))/ the capacity of mobile phone battery
Take for iPhone 6 for example:
Capacity of Power Bank: 30000mAh
Power bank conversion efficiency: 3.7V/5V
Phone inner core conversion efficiency: 80%
The capacity for iPhone6 battery: 1810 mAh
(30000mAh x 3.7/5*80%)/1810=9.8
So 30000mAh Power bank, the total Number of Charger for iPhone 6 is 10 times.
