• In regards to efficiency, all our PowerCores burn 30-40% of their power when they are charging other devices.  So the PowerCore III 20000 has 20,000mah of power, but the power left for charing your device is in fact 12,000 - 14,000mah. Since your device has a battery capacity of 3687 mah, it should be able to charge 3 times with that PowerCore.
